What is the best way to introduce towels?

How long is the towel suitable for use? At the annual meeting of the Home Textile Association held not long ago, according to home textile experts, personal towels should be replaced every 30 days or so, not more than 40 days at most. Towels have been used for a long time and become hard and uncomfortable. The most important thing is that they are contaminated with a lot of bacteria, which is harmful to human body. Towels are made of pure cotton yarn. Cotton fiber is a tubular structure with hollow cells and can store water. Its main chemical component, cellulose, contains a large number of hydrophilic genes and can absorb water. This moisture absorption and water storage performance of cotton yarn makes the towel feel comfortable and has strong decontamination ability, which is suitable for washing your face. But it is precisely because of this characteristic that it provides convenient conditions for the breeding of bacteria. Bacteria like warm and humid environment best. Towels are in a warm and humid state for a long time, and after a certain period of time, they become a paradise for bacteria to breed. In addition, grease, dust, impurities in water and bacteria in the air on human skin are deposited on towels, and then wiping the skin with such towels will not only not clean the skin, but will stain the skin and block pores. Ladies who like makeup and children with fast metabolism have oily skin and towels are more susceptible to infection, which is particularly harmful. Experts analyze towels, don't wait until they are broken before using them. Professionals say that the service life of towels should be three months. It should be advocated that "three men and four women are used to it", and there are hidden dangers behind it. For example, using towels, in hot summer, especially in Guangdong, unscientific use of towels will affect health. A few days ago, the reporter learned that there are many bad habits in using towels when interviewing experts from the towel professional Committee of China Household Textile Industry Association. Experts suggest that everyone should have more than one towel, especially in summer. Small towel, many people didn't pay attention to it before, however, it has to accompany people's life. If there are a lot of bacteria and viruses in the towel, they will penetrate into the body through the five senses and skin, affecting health. It is scientifically proved that coins, bedding and towel products are the three indirect transmission media of infectious diseases. Due to the influence of traditional living habits and consumption concepts, many consumers ignore the health care function of towels and continue some unscientific use methods: 1. One towel for many people; 2. One towel is multi-purpose; 3. Do not break or change, reuse; 4. Do not pay attention to towel hygiene; 5. Ignore the harm of fake and inferior products. The above-mentioned bad habits have aroused consumers' high vigilance in the national fight against SARS. So how to get rid of these bad habits and choose and use towels scientifically? The choice of towels is exquisite: (1) choose and buy. Try to buy in large shopping malls, supermarkets or specialty stores and choose products from regular manufacturers. (2) recognition. Qualified towel products should have standardized identification, and indicate the manufacturer, place of origin, contact number, trademark, implementation standard, washing method, etc. (3) feel. Quality towels are generally soft, fluffy and elastic. (4) appearance. Good towels have bright colors, clear patterns, even terry and neat seams. (5) Towel products with qualified smell should have no peculiar smell. In addition, families can also do some quality appraisal when using towels. If the water drops dripping on the new towel can be absorbed quickly, it means that the towel has good water absorption. High-quality towels have elasticity and friction when used, and will not fade when entering water. Inferior towels have poor water absorption, are loose, inelastic and slippery when used, and fade seriously after entering water, which is harmful to skin and eyes. Small towels should also be used scientifically (1). In recent years, the towel industry in China has developed rapidly. The products are complete in variety and grade, and rich in colors, such as square towels, face towels, bath towels, napkins, tea towels, kitchen towels, etc. , as well as children's towels, adult towels, ladies' beauty towels, etc. , can meet the needs of different consumption levels. According to China's national conditions, the minimum standard for consumers to use towels individually should be two men (strips) and three women (strips), and three men (strips) and four women (strips) should be advocated. (2) Correct washing and regular disinfection. When washing your face or taking a bath, rinse it with shower gel and water first, and then dry it with a dry towel, which can reduce the adhesion of human dirt to the towel. Towels should be cleaned in time after use, disinfected with boiling water for 10 minutes every week, and the hanging place should be ventilated, preferably dried or dried in time. (3) timely replacement. Changing towels in time is the key to change the misunderstanding of traditional consumption. The service life of towels is generally three months. (4) Special treatment. The hardness of the towel is mainly due to the combination of free calcium and magnesium ions in water with soap to form calcium and magnesium soap, which adheres to the towel. The long-term accumulation of dirt residue is also a cause of hardness. To soften, add 30g of soda ash or a suitable softener to1.5kg of water and cook for10min. After the towel becomes greasy, it can be washed with salt water. When buying towels, you can use the following six criteria to prevent being cheated. 1. fluffy texture, soft to the touch. Such a towel is elastic in the hand and sticks to the face, giving people a soft feeling of sticking to the face. Towels should not be dry and hard, so as not to hurt the skin. 2. Bright colors. Whether it is a printed towel or a plain towel, as long as the materials are exquisite and the technology is home, it will be very bright and fresh at first glance. Don't buy a towel as weak as the old one, because this kind of towel is generally simple in technology and poor in materials, which is harmful to your health. 3. Clear pattern, accurate printing, fullness, novelty and sense of the times. Towel is not only practical, but also a work of art, lifelike, a painting and an ornament, which gives people a kind of spiritual enjoyment. Putting it anywhere in the room will not spoil the scenery and become redundant. Don't buy fake products with rough printing and different shapes, so as not to reduce your taste and pollute your room. 4. High water absorption. Towels have particularly high requirements for hydrophilicity. When the towel is wiped, the water is dry and the dust and dirt are removed. This requires high-quality cotton yarn, advanced scouring and printing and dyeing technology, and perfect testing methods. Don't pull vegetables into the basket, it will slide on your face and won't absorb water. Non-decontamination towels accompany you and affect your quality of life. 5. The style is novel and the production is fine. Towels can have different styles, such as spiral, cut velvet, plain color, printing and so on. You can also add satin edge, embroidery, applique, beard arrangement, inlay, fabrics of various colors and patterns, etc. There are also various means to use them. This kind of towel is generally made of exquisite materials and high quality, plus fine trademark sewing. And the towel looks elegant and can't be faulted. With reasonable packaging, people feel very comfortable. 6. The price is reasonable. Price reflects value as well as cost and socially necessary labor time. Prices between factories are high and low, but they should not be outrageous. If the price is far below the value, you should be careful There are some "fakes" in it, which are either shoddy or have other demands. We believe that buying towels must be genuine. Don't buy waste at the lowest price. Selection of sewing needle and thread. Usually, sewing refers to connecting clothes with sewing thread, or embroidering certain decorative patterns on the surface of clothes. In order to achieve perfect sewing effect, besides the good performance of the sewing machine itself and skilled operators, it is also required that the specifications of sewing needle, sewing thread and sewing material match. Sewing needle is an important part of sewing machine. There are hundreds of kinds of sewing needles made in China alone. The working nature of the machine determines the choice of needle. Machines with different properties should be equipped with different types and specifications of needles, such as 96' 1 or 88' 1 needles of flat sewing machine; Sewing machine use 18' 1 needle, etc. No matter what kind of machine it is, the specifications of needles, that is, the number of needles, should be selected according to the nature and thickness of sewing materials in the sewing process. Generally speaking, the needles used in textiles and knitwear are all ground into conical shapes. When sewing leather and similar sewing materials, special-shaped needles, such as spear tips, diamond tips and reverse twist tips, are used to increase the strength of the needles and obtain good sewing effects. The selection conditions of needles are as follows: 1. If the strength of the needle itself allows, try to use a thinner needle. 2. Thick materials have high puncture resistance. In order to prevent needle breakage, a thicker needle with strong stability should be selected, and the thicker needle is not easy to stab the thicker sewing fiber. 3. The puncture resistance of thin materials is small. In order to prevent the appearance of sewing materials from being affected by pinholes, a thinner machine needle can be selected. 4. The sewing needle should be smooth, free of spikes and rust spots, and the needle tip should be blunt enough to prevent the sewing fiber from being damaged. After the specification of sewing needle is selected, choose sewing thread. The stitches are pure cotton, polyester cotton, blended yarn, polyester, rayon and so on. Generally, it is made by twisting two, three, four and six strands of single yarn. The twisting direction can be divided into S twist and Z twist. Generally, flat sewing machines use Z-twist needles, and good quality S-twist needles can also be used on other sewing machines. Cotton sewing thread has good sewing performance, but it shrinks more when washed than synthetic fiber thread, and its strength, chemical resistance and wear resistance are also worse than synthetic fiber thread. High-quality mercerized cotton thread is expensive, so cotton sewing thread is rarely used now. Short fiber polyester sewing thread has low cost, excellent sewing stability, durability and sewing performance, and is suitable for all conventional clothing sewing. Sewing machines generally use cotton thread, but because of the high cost of cotton fiber at present, polyester-cotton thread is generally used instead. When choosing the thickness of sewing thread, we should first consider using fine sewing thread, which can be considered from the following aspects: 1. The bobbin volume of lock stitch sewing machine is limited, and the use of fine sewing thread can accommodate longer sewing thread, which saves shuttle changing time and has high working efficiency. 2. The size of fine sewing thread is small, and the chain sewing feels good. 3. The space occupied by fine sewing thread is extremely small, resulting in less fabric deformation and sewing wrinkle. 4. Small gauge needles can be used for fine sewing threads to avoid pinholes on fabrics. 5. Fine sewing thread can also reduce the protruding seam marks, make them trapped in the inner layer of the fabric surface, and reduce the impact of wear. In the process of sewing, it is necessary to ensure that the specifications of sewing needle, sewing thread and sewing material match, so as to form correct stitches. In addition, it should be noted that: firstly, the torsion of the suture should be considered in the sewing process, and the purpose of the suture torsion is to increase the strength and elasticity. However, if the twist is too large, the suture will roll up, which will affect the normal formation of the coil. Generally, a suture with a length of 1 meter should be adopted, and both ends of the thread should be grasped to make them closely combined, and the natural twist number of the two threads should not be greater than 6, otherwise it will easily lead to the failure of needle jumping. Secondly, when sewing, if the sewing material is thin, fine needles must be used, and at the same time, the rising amount of machine needles should be increased, because the friction between sewing thread and sewing material is small. If the rising distance remains the same, the width of the upper thread loop will be relatively reduced, which will affect the normal crochet and lead to the failure of needle jumping. If it is a thick and hard fabric, the situation is just the opposite. Therefore, it is necessary to adjust the relative position of the crochet mechanism and the needle. In the process of garment making, the choice of sewing needle is a very simple problem. Actually, it's not. It is necessary to meet both technical requirements and aesthetic requirements. Only by considering the color matching of sewing thread and sewing material and the fineness selection of sewing thread can we achieve more perfect results.
