Summary of personal work in textile mill

Textile industry as a flammable industry, its cotton, cotton yarn, cotton cloth and so on are flammable, and its safety is directly related to people's life safety. The following is a summary of my personal work in the textile mill. If you like, you can share it with your friends around you!

Summary of personal work in textile mill 1

In order to make the long summer vacation full and meaningful, I regard the cultivation of ability as another theme of college life. This summer vacation, I conducted a social practice. The specific situation of this practice is now reported as follows:

Practice time:

20 August to 25 August 200818;

Practice unit:

Jinan Cotton Textile Factory;

Actual goal:

Have a deeper understanding of Yongjing cotton yarn textile factory, increase your knowledge and improve your ability in all aspects;

Practice process:

August 20-2008 18, I came to the cotton yarn textile factory and started my one-week social practice. On the first day of internship, Li Shifu, an old employee, gave us an overview of the cotton yarn textile factory. Then explained the whole process of clothing making for us, which is convenient for our next practical study. The following is a summary of what I have learned these days.

First, the process of yarn metamorphosis

Clothing fabrics are all made of yarns after preliminary processing. Under the arrangement of the factory, we were divided into three groups. Under the leadership of the workshop master, we first visited the yarn processing workshop.

1, raw yarn → colored yarn

Generally, companies go outside to buy raw silk and process it after entering the factory. Raw yarn is generally pagoda-shaped. In order to dye the yarn conveniently, the bobbin loosening machine is usually used for reversing, so that the original yarn is wound on the straight bobbin. Or use a more direct method-twisting yarn to wind the original yarn into loop yarn.

According to the workshop master, no matter what form of raw yarn is inverted, each bobbin is almost 850 grams. The main purpose of this process is to keep the yarn loose and make the later dyeing more uniform. After processing to a certain amount, it can be transported to the next process for processing.

The next process is yarn dyeing, which adopts pre-wetting or pre-drying to keep the warp yarn basically the same water content before sizing. Put the yarn into the designated container for boiling and soaking. Dyeing vats vary in size, and one vat can dye 60 straight cylinders at a time. The bath ratio of the small sample should be consistent with that of the large sample, and should be controlled around 1: 10 as far as possible, and not more than 1: 15 at most. Dyeing adopts full outflow, the pump speed starts from small to large, and gradually moistens to ensure uniform water droplets on the upper end of the shaft.

Squeeze water for 4 times after dyeing for about 60s each time, and control the water content at about 100%. The interval of sizing on the shaft should not exceed 24 hours to prevent color stratification. For some special yarn counts and sensitive colors, the next process must be carried out after hot air drying. The process of hot air drying has also become pumping, and dyeing has basically ended after this process.

In order to make it easier to warp the yarn into cloth in the later stage, the enterprise will change the dyed yarn back to pagoda shape. At this time, a winder or a winder grooved drum machine is used, and the straight drum or twisted yarn is changed back into an inclined drum shape by the machine. Prepare to warp.

2, warping → sizing

The so-called warping is to wind the core-spun yarn into warp beams in parallel according to the number and length required by the warp knitting process under certain technological conditions for use by the warp knitting machine. Warping has three clock forms, namely sectional warping, axial warping and sectional warping. Generally, the warping temperature is controlled at 20~26℃ and the relative humidity is 60~70%. And the long fiber and the short fiber must be separated.

As an important preparation process before weaving, especially with the rapid development of high-speed looms, the requirements for warp beam quality are getting higher and higher. The main purpose of sizing is to make the sized yarn have the following characteristics:

1) has enough wear resistance;

2) Uniform tensile strength and tension;

3) Good slurry coating to reduce hairiness.

Sizing machines are widely used for sizing all kinds of warp yarns, including single-fiber warp yarns and blended yarns that can make fabrics show unique styles in elasticity or other aspects, such as Lycra, polyester and viscose blended yarns. Therefore, starch or other binders should not only be used to make the yarn tensile and smooth, but also ensure the yarn to pass through healds, reeds and other parts smoothly in the weaving process. At the same time, sizing can reduce fabric defects and ensure fabric quality. Before sizing, yarn characteristics, loom type and fabric structure (plain weave, twill weave, satin weave, etc. ) must be considered. At the same time, attention should be paid to the selection of slurry variety, slurry concentration and proportioning method to avoid adverse effects on subsequent production. For example, if the fabric is to be dyed, biodegradable size must be used to avoid affecting the color of the fabric or producing stripes on the surface of the fabric.

In addition, the output and quality of looms can be improved by sizing. Therefore, the sizer must know all the information related to the yarn, including its physical properties, pre-treatment and post-treatment processes, loom types and final production processes. Therefore, sizing is to use unused size, equipment, post-treatment technology and processing methods according to each fiber and yarn.

At present, the sizing of cotton yarn or blended yarn has been greatly developed and improved. However, for twisted yarn, bobbin yarn or multi-mesh yarn, sizing is generally not needed. Small companies generally use cheap sizing combinations to size warp beams, and rely on adding grease or other components to improve weaving quality. The development of new technology and the restrictions on pollution and industrial waste urge people to constantly study and improve various sizing processes.

Second, the origin of fabrics

1, threading and knitting

Fabric is made of yarns, so the warp yarns must be determined first. The workshop supervisor passes each yarn through the eye of the needle for weaving. This process is called threading. After the yarn threading is completed, the master will put the finished yarn on the machine for knitting.

Usually, yarns are used as warp and weft to form fabrics according to various fabric structures. Comprise three parts: warp beam formation, package preparation before weft weaving, weaving and grey cloth finishing. Weaving is an important part of textile industry production. According to the types of raw materials used, it can be divided into cotton fabrics, wool fabrics, silk fabrics and hemp fabrics, and their products are collectively called woven fabrics. Woven fabrics have a wide range of varieties and uses. According to different requirements, choose suitable yarn raw materials and suitable fabric structure.

2. Fabric finishing

This kind of fabric needs a series of finishing before it can be used to weave clothes. Post-finishing is a technical treatment method to give fabric color effect and metal effect (smooth, suede, crisp, etc.). ) and practical effects (waterproof, non-felting, non-ironing, heat resistance, etc. ). Finishing is a process to improve the appearance and feel of fabric, improve its wearability or give it special functions by chemical or physical methods.

3. Cloth inspection

Cloth inspection is the last process of fabric production, including various physical structure inspections, such as weight inspection, width inspection, length inspection, color difference and color fastness inspection. Common fabric defects are: printing stains on the back: in the printing process, there is often a layer of pad cloth on the back, which makes the printed fabric have printing marks on the back. Twill track: Knitted and woven fabrics, the grain is not straight or right-angled, forming a twill track. Bow yarn: Bow warp or bow weft (weaving and knitting), often caused by uneven tension. Roving: coarse weft or bow weft caused by the exhaustion of weft in weaving process, and warp hanging caused by other factors: the tension of loom fabric is too high, exceeding the normal requirements, and the weft usually shrinks due to broken ends; The weft yarn of shuttleless loom is not straight after entering because of lack of tension. Less yarn: the yarn is broken and the loom and knitting machine are still running. When there is a similar situation in general fabrics, a small part can be corrected by hand needle or automatic cloth inspection machine. What cannot be corrected should be regarded as rework, and continuous defects must be cut off. Only qualified fabrics can enter the garment workshop for garment cutting, sewing and other processes.

4. Evolution of fabrics

After a series of processing and finishing, the fabric enters the production workshop for garment cutting and sewing. The cutting department is equipped with two sewing machines, one sewing machine, one cutting bed and two employees. General companies have their own printmakers who specialize in printing. The production of sample clothes has a guiding role for customers and workshop employees. After the sample clothes are approved by customers, they will enter the typesetting work. There is a master in the typesetting room, and the bed is about 139 times 563. The main job is to draw all the patterns on typesetting paper with the smallest area or the shortest length according to the cutting scheme and specifications. Use two pairs of movable cross bars with sharp hooks to cut the fabric. The equipment can change the length of the fabric at any time, then reasonably pull the fabric to a certain thickness, then fix the fabric around (in order to keep the fabric tidy after moving), move it to the cutting machine, then punch a single layer of manual cloth, and finally batch, bundle and stack it.

The production department has a workshop: garment sewing workshop. The workshop has 15 sewing machines and 10 double-thread sewing machines. At the same time, each sewing machine is equipped with product sewing process requirements and production processes of some processes, such as hidden thread, open thread, needle distance of 65,438+03-65,438+04 stitches, 3-point sewing and open thread of 65,438. Grade 8, the factory adopts assembly line, throwing parts and operating in different categories. The sewing machine is equipped with specialized personnel, which can be adjusted in time according to the production situation. The workshop is also equipped with a radio, and a good environment allows employees to have a good mood anytime and anywhere, so that they can finish their work better.

Practical experience:

In this short time, I have gained a lot of things that I can't find in school and textbooks. Social practice is an important part of university study, which increases students' knowledge, lets us know some basic operation processes of the factory and lays a solid foundation for our future study and work.

Through this social practice, on the one hand, I have exercised my ability and grown up in practice; On the other hand, I have also made my own contribution to the society. After returning to school, I will cherish my time at school more, strive to master more knowledge, practice and test my knowledge in depth, and exercise my ability to lay a solid foundation for better serving the society in the future.

The short social practice passed quickly, and I learned a lot from it, which will benefit me for life. Social practice has deepened my feelings with people from all walks of life, narrowed the distance between me and society, broadened my horizons, increased my talents in social practice, and further clarified the road to success and historical mission of our young students. Society is a big classroom for learning and education. In that vast world, our life value has been reflected, laying a more solid foundation for more intense competition in the future. I hope that I will have such an opportunity in the future to exercise myself from practice.

Summary of personal work in textile mill II

My personal understanding of contact with society is that, as people often say, a university is like an ivory tower. During my study in the university, I had little direct contact with the society, and little contact was indirect contact. In college, our understanding of society is like looking at the vast scenery outside from the window of the ivory tower, and we can only see a vague appearance. University is just a small class, and society is the real big class. Social practice in summer brings us an opportunity to experiment in a big classroom, a platform for real contact with society. Only by experiencing social tempering can we mature and improve ourselves in growth.

Unconsciously, we will be faced with the choice of finding a job and coping with life. What kind of job to find should be everyone's concern. This summer's summer internship is a good exercise opportunity for me. School and society are two completely different groups. At school, we are protected and cared by the school, but we can only cope with difficulties and solve problems in our work.

The first feeling of coming to Dongguan Deyongjia is the enthusiasm brought by Deyongjia. Whether at work or in life, we are so enthusiastic. Although we are in different places, it makes us feel the same.

The first day of coming to this strange environment is, of course, familiarity and understanding of the new environment. First of all, I visited various factories, from power plants to spinning mills, from weaving mills to printing and dyeing mills. Deyongjia is a one-stop production line, and each factory covers a large area. Each factory is carefully designed, which makes the contact between factories convenient and fast.

In addition to a good working environment, there are relatively perfect entertainment facilities. It allows employees to enjoy a simple spare time after intense work.

The company assigns students of different majors to various factories according to their majors. I was assigned to a spinning factory for an internship, where I practiced for a month, and I had a deep understanding and many feelings. Just came to this factory and put forward strict requirements for us. Factories are different from schools, where there are large-scale machinery and equipment rotating at high speed everywhere, and unsafe factors may be hidden everywhere, which requires us to pay more attention and always guard against them. Safety is always the first there, and the safety of employees is the first, so anything unsafe is not allowed to happen, so not only we but also employees are required to have a high sense of security. We just got there, so we need more attention.

Of course, every internship should have the necessary internship plan. After giving us strict safety education, the factory director made a detailed internship plan and gave us a general introduction to the technological processes of various departments and the whole spinning mill. The internship plan is a very specific and detailed plan. What do you do in which department on a date? They are all carefully arranged, so let us point out the direction of our efforts this month.

The director has made a detailed plan for our internship, and the specific information is reasonable, so he can have a preliminary understanding of various departments in a limited time, have a roughly coherent concept in his mind, have a general understanding of each process, and have an understanding of the names and functions of different machines and equipment.

During the internship, there are several hands-on opportunities, which is a good learning opportunity, because in the hands-on operation, we can find many unexpected problems. It is a rare learning opportunity for us to find problems in operation and solve and answer them by consulting a coach or master.

The textile industry is to find and solve problems from the actual production operation, which can not only exercise our hands-on operation potential, but also better exercise our thinking and foundation for dealing with problems.

In the actual production operation of the workshop, you can find many problems that you have never seen before, exercise your thinking and think about where the problems are. Can constantly enhance the potential of self-handling problems and accumulate different experiences for themselves. The textile industry is more from the accumulation of its own experience.

We not only know our work like the back of our hand, but also have good accommodation in our daily life. We also opened up a lot of horizons there, and seemingly ordinary employees were hidden one by one. The company provides all kinds of entertainment facilities for employees, and provides simple and pleasant entertainment activities for employees after intense work. Their performance was really wonderful.

While paying attention to the development of enterprises, the company also pays great attention to the development of corporate culture and the continuous improvement of comprehensive potential. But I understand that in the current environment, it is not only limited to the study of professional knowledge, but also integrated into the lives of the masses. Knowledge is infinite. We not only study in textbooks, but also study by ourselves, because we have to deal with the outside world instead of textbooks in the future.

This internship really benefited me a lot and I was deeply touched. Many things are not as simple as I thought, and we still have a lot to learn. This time let me clear the direction, and also laid the foundation for myself to study harder in the future.

Practice is the criterion for testing truth. This practice made me understand that I am so lacking, and I need to make constant efforts to enrich myself and make up for my shortcomings in future study. Constantly improve yourself, so as to meet all kinds of challenges in the future without fear. Let's go

I have been in the League for more than half a year. At this moment of bidding farewell to the old and welcoming the new, reviewing the work process in the past six months and summing up the experience and lessons in the work are conducive to fostering strengths and avoiding weaknesses in future work and doing our work better. From the leader, I realized my dedication and care, and from my colleagues, I learned diligence and self-discipline. This is my best summary of my work in 20-2000. No matter what position I am in, I must do everything in time and accurately.

The workshop practice time is relatively short, and I can only have a general understanding of each technological process, but I can't deeply understand the problems in production. Of course, this is not a problem overnight, and I need to learn slowly in the future production tracking. After transferring to product development, I mainly study customer sample analysis. Now I can skillfully analyze the yarn count, composition, gram weight and other indicators of various varieties, and try to avoid re-inspection. The most important thing in sample analysis is to be careful, and the feedback is the same, so as to ensure the accuracy of what goes out. But at the same time, we also found some shortcomings. Basically, I can finish some work arranged by the leaders in time, but sometimes I take it for granted that things are not urgent, and when other things come back, it is too late or it has affected the normal progress of other work; In addition, the lack of learning initiative is also its own deficiency, which can't pay attention to the latest trends of wool spinning industry in time and can't keep up with the pace of enterprise development, so it should be corrected and avoided in future work.

Next year, we will mainly do a good job in the following aspects:

By reading more, asking more questions and listening more, I further improved my work skills. Objective: To know the technological formula and track the production progress in time.

Develop a good habit of collecting information.

Through the information platforms such as textile newspaper, wool spinning technology and network, we pay attention to the development trends, the latest fashion trends and the application of new technologies in wool spinning industry, and understand how much progress others have made, so as to have a stronger sense of urgency and a clearer sense of work direction.

With the increasingly fierce market competition in wool spinning industry, the requirements for technicians in all aspects are getting higher and higher, which will inevitably prompt me to devote myself to my work with a more rigorous working attitude and a stronger sense of responsibility. I will constantly sum up and reflect, constantly spur myself to replenish energy and improve my quality and professional level to adapt to the development of the times and enterprises.

1. has the characteristics of a shuttle loom.

A "loom" that uses a shuttle as a weft insertion device to introduce weft into a shed. The disadvantages of shuttle loom are large vibration, noise and material loss, which is not conducive to high yield. Therefore, ordinary shuttle looms are gradually being eliminated. For the sake of safe production, shuttle looms are usually divided into left-handed and right-handed vehicles. The one with a switch handle on the right side of the machine is called a right-seat car, and the other is called a left-seat car.

2. Main institutions and auxiliary devices

2. 1 main institutions

Shedding mechanism: make warp move up and down in vertical direction to form shed;

Shuttle picking mechanism: introducing weft into shed;

Beating-up mechanism: beating the weft introduced into the shed to the weaving shed to form fabric;

Reeling mechanism: the woven cloth moves longitudinally and winds on the wooden roller.

Let-off mechanism: send out the warp yarn quantity needed in weaving process in time.

2.2 auxiliary mechanisms and devices:

Warp yarn breakage closing device, weft yarn breakage closing device, warp yarn protection device, trimming device, transmission braking device, flying shuttle protection device, continuous weft feeding induction device and automatic shuttle changing mechanism. The biggest difference between shuttle loom and air-jet loom is that there is no electronic sensor on this loom. Shuttle closing, warp-breaking closing, weft-breaking closing and reed closing are all transmitted to the parking shaft toggle switch through mechanical triggers to realize car closing.

Fourth, shortcomings and learning gains.

Due to the tight study time, I was not familiar with the environment, equipment, products and technological processes of each workshop at first, and the study time of each workshop was limited, so I could not fully grasp the functions of all equipment components in each workshop. However, through three months of in-depth practical study, I have a deeper understanding of the working principle, performance and basic unit composition of the equipment in each workshop of the factory, which has laid a good foundation for continuing to strengthen equipment management and ensure the equipment to work in good condition in the future.

Thanks to the learning opportunities given by the factory leaders, I will learn in the workshop practice. In the future work, I will constantly improve my working ability and level, overcome my shortcomings, improve myself, apply what I have learned to practical work, do a solid foundation work according to the company's equipment status, contribute to the company's development with full enthusiasm and enthusiasm, and do my part for the company's equipment management.

Summary of personal work in textile mill 5

Through three months of study, I have a deeper understanding of the basic situation and working principle of spinning frame, air-jet loom and shuttle loom. The research situation is summarized as follows:

I. Post-spinning Workshop

/kloc-From July 4th to June 8th, 0/8, I studied in the maintenance, preservation and leather roller room of the back spinning workshop. During this study period, it was a hot summer day, and the workshop was like a stove. Every time I change the traveler, tap the spindle and change cars with the master in the workshop, I always sweat, and the masters are extremely hard. In this environment, the masters still patiently explained to me the main mechanism and working principle of the spinning machine. At the same time, under my serious study, I have a deep understanding of the overall situation of the equipment in the post-spinning workshop, the main mechanism, working principle and process knowledge of the spinning frame.

1. Status of existing equipment in post-spinning workshop:

178 spinning frame, 6 German automatic winders, 5 Japanese Murata automatic winders, 13 winders, 2 yarn steamers, 1 leather roller oiler, 1 pneumatic leather roller and 4 leather roller grinders.

2. Principal institutions

2. 1 feed mechanism

The feeding mechanism is mainly composed of roving frame, yarn guide rod and traversing device. Its main function is to support the roving, feed the roving into the drafting mechanism smoothly, reduce the accidental drafting of the roving, and protect the apron cots.

2.2 Drafting mechanism

The fed roving is further evenly stretched and refined to the linear density required for yarn formation. The main components of the drafting mechanism include: drafting roller, cots, aprons and needle collectors.

2.3 twisting and winding mechanism

Twisting and winding, as well as lifting and molding, are almost simultaneous. This part of the mechanism includes blade plate, yarn guide hook, yarn separating plate, platform plate, platform, traveler, bobbin, spindle, roller, spindle reel and other main components, as well as the lifting device and molding transmission mechanism of platform plate and blade plate.

3. Spinning frame process:

3. 1 drafting: the roving is unwound from the roving tube on the suspension spindle and fed into the drafting device through the yarn guide rod. The fed roving is stretched, elongated and refined uniformly by the surface speed difference of three pairs of rollers until it meets the requirements and the fibers are parallel to each other. This process is called drawing.

3.2 Twisting: Drafted whiskers are ejected from the front roller, passed through the yarn guide hook, and passed through the traveler. Travelers rotate at high speed on the platform, and one twist is required for each turn. This process is called "twisting".

3.3 Winding: The twisted yarn can have certain strength, elasticity and luster. After the sliver is twisted into yarn, it should be wound on the bobbin. The wire shaft sleeve is on the spindle and rotates at high speed synchronously with the spindle. On the one hand, the tensioned yarn strips drive the traveler to rotate at high speed, resulting in twisting; On the other hand, the yarn strips continuously output from the front roller and spun after twisting are wound on the bobbin in turn. This effect is due to the fact that the rotating speed of the traveler lags behind that of the bobbin. The traveler is driven to rotate by the tension of the yarn belt. When the traveler slides on the rim at high speed, its rotation speed is actually lower than that of the spindle due to the friction with the platform rail and air resistance, and the speed difference forms the winding speed, which is suitable for the output speed of the front roller. This action completed at the same time as the twisting process is called "winding".

Second, the injection workshop.

July, 20091August, 2009 19, studying in Jet Maintenance and Automobile Modification Group. Maintenance is mainly responsible for the overhaul and maintenance of the car, and security is mainly responsible for the big bad car and process modification. Through the study, I have a certain understanding of the role of air-jet workshop and air-jet loom components, how to maintain the normal work of the loom, and the main technological knowledge. The products in the air-jet workshop are all finished products, so we should pay attention to safety when checking and repairing cars, and pay special attention not to cause defective fabrics and tarpaulins.

1. Equipment status of air-jet workshop

At present, there are 374 air-jet workshops in Tsuda, Xianyang, Japan and Pusheng, Shaanxi. The comprehensive performance of Tsuda loom in Japan is obviously better than that of domestic loom, and there are few faults in production. Therefore, domestic looms are the key objects of daily maintenance.

2. The characteristics of air-jet loom

Air-jet loom uses air as weft insertion medium. The compressed air jet generates friction traction on the weft, which brings the weft into the shed. The purpose of weft insertion is achieved by the jet generated by the air jet. It has the advantages of high speed and high efficiency, but it consumes a lot of energy and needs a lot of compressed air, which inevitably often contains some water. If it cannot be filtered and removed in time, it will have a certain impact on product quality.

3. Air-jet loom technology

On the basis of traditional loom machinery, air-jet loom comprehensively uses computer technology, sensing technology, frequency conversion speed regulation technology and air-jet technology. The electronic detection device transmits the detected signal to the computer in real time, and the computer controls the movement of the whole machine through analysis and calculation, and transmits the data to the touch screen to display various production data. The operator can set parameters on the touch screen as needed to realize man-machine dialogue. The computer can issue corresponding instructions to control the tower lamp according to different faults, so that the lathe operator can quickly judge the problem according to the color of the tower lamp, which simplifies the operation and improves the work efficiency.

4. The main mechanism of air-jet loom

Shedding motion mechanism, weft insertion motion mechanism, beating-up motion mechanism, let-off motion mechanism, winding motion mechanism, selvage device, weft breaking self-stop device, warp breaking self-stop device and transmission device.

5. Main process items

Opening time, weft insertion time, loom tension, warp position line, back beam height and back position, drop frame height and back position, heald frame height, reed number, vehicle speed, width and doffing length. The car changing group is responsible for changing the speed, the height of the rear beam, the height of the heald frame, placing the cam, adjusting the L value, adjusting the side shears, etc. According to the parameters of the process sheet issued by the technician.

Third, the space shuttle workshop.

From August 20th to September 30th, I mainly studied in the shuttle maintenance, security, shuttle room and refueling room. The maintenance department is mainly responsible for the maintenance of live cars in motion. Security guards are mainly responsible for flat cars, which is relatively less difficult than maintenance. The shuttle room is responsible for polishing the shuttle so that it does not hang yarn, correcting the shuttle so that the bobbin is in the best position, and repairing the broken shuttle. The refueling room is responsible for refueling and lubricating the shuttle car 10 13. Shuttle car is different from jet car, it has no centralized oil supply, and it has fast oil hole, medium oil hole and slow oil hole, so it needs a lot of manpower to refuel to maintain the normal operation of the machine.
