How do head enterprises strive to make sustainability run through the whole textile process?

With the continuous improvement of people's living standards, consumers are increasingly pursuing the concept of green environmental protection and sustainable development. In the post-epidemic era, the concept of health, environmental protection and sustainable development has become a new trend in the textile and garment industry. Conducted to the upstream, from fiber to spinning, weaving, dyeing and finishing. In 2020, the sustainable development trend throughout the whole process of cotton textile will become more prominent. Both the research and development of the former fiber and the dyeing of the latter fabric practice the concept of green, environmental protection and health to meet the needs of the end market.

Start a good life from the optical fiber end

Fiber is the basis of "clothing". The application of functional and green fiber can lay a healthy background for the textile and clothing industry and start a healthy life for the public. In recent years, more and more chemical fiber enterprises and spinning enterprises have joined hands to make sustainable textiles bigger and stronger, just like Saideli Group and its downstream customers.

Saideli is one of the leaders in the global cellulose fiber industry. The Youkesantaibe fiber released last year, through injection spinning technology, disperses active antibacterial substances evenly on the surface and inside of the fiber, and has inhibitory effect on microorganisms such as bacteria, fungi and viruses. The person in charge of the product introduced: "Because of the pre-spinning injection technology, the distribution of active antibacterial substances is more uniform, which makes the antibacterial performance excellent and lasting, and still maintains excellent antibacterial effect after washing for 50 times. Antaibei fiber is also beneficial to reduce body odor (such as sweat odor), effectively eliminate odor, and has good gas adsorption. After washing for many times, the antibacterial and deodorizing effect is still obvious. In addition, Antaibei fiber comes from 100% high-purity dissolved wood pulp, and its quality is stable. Because of its fiber molecular structure, it has natural skin-friendly characteristics. In addition, under the same spinning conditions, the yarn containing Youkesantaibei fiber has better spinnability indexes such as strength, defects and hairiness. At the same time, the high strength of yarn brings higher fabric bursting force. The color fastness of the fabric reaches 4-5, and the dyeing consistency is high. "

In addition to Antaibei fiber, sardar cellulose fiber products introduced earlier are also well received by the market. The raw material of sardar cellulose fiber comes from natural wood. After technological innovation, it is an environmentally-friendly and traceable green fiber. The waste can be naturally degraded and has no pollution to the environment. Xinhuayuan Group, as a long-term partner of Saideli Company, has jointly developed Saidil cellulose fiber series yarn. Through technical optimization and innovation, pure and blended products of 50 to 120 siro compact spinning were developed. In addition to the advantages of environmental protection, the yarn is soft and smooth, the color is moderate, the fabric feels good, the synthetic fiber is strong and spinnability is good, and the fabric has good shape and dimensional stability. At present, Seidel cellulose fiber series yarns have been successfully applied to knitting, weaving and warp knitting products. Chen Wen, president of Xinhuayuan, said that Xinhuayuan has been cooperating with Saideli to innovate products and put the concept of environmental protection and sustainable development into practice.

Carry out environmental protection recycling to the end.

Nantong Shuanghong Textile Co., Ltd. (hereinafter referred to as "Nantong Shuanghong") has been practicing the new development orientation of "science, technology, fashion and green" in China textile industry, actively promoting the sustainable development strategy of textiles, and firmly believing that new fibers and technologies that conform to ecological environment protection and sustainable development are the unchanging direction in the future.

Nantong Shuanghong is an enterprise specializing in spinning, thread making and trading. Its product quality is leading in the industry, meeting the needs of more than 4,000 domestic customers and international fashion brands such as LV, ZARA, H&M and Uniqlo. Focus on one yarn for 43 years and take the road of specialization, differentiation, customization and quality. In the face of this year's sluggish textile market environment, the person in charge of the enterprise said that Nantong Shuanghong will carry out the environmental protection cycle to the end and seek new breakthroughs.

The blue crystal viscose EV fiber series yarn developed by Nantong Shuanghong explains a brand-new concept of environmental protection. It is reported that the blue whale viscose EV fiber series yarn adopts environmental protection technology in the whole process, and always maintains strict environmental protection standards from raw material extraction to production, distribution and final disposal. Compared with ordinary viscose, it can reduce gas emission by 50% and its influence on water quality. In addition, Nantong Shuanghong also has the product of "environmentally friendly recycled polyester yarn series", which is made of recycled PET bottle pieces recovered from waste polyester beverage bottles, sorted, crushed, cleaned and dried, and then recycled polyester fiber is produced from the recycled bottle pieces, which is made of 100% recycled raw materials. Its products have traceability, high transparency and authoritative certification, and have passed GRS certification.

Like Nantong Shuanghong, Dezhou Huayuan Ecological Technology Co., Ltd. (hereinafter referred to as "Dezhou Huayuan") also practices the concept of sustainable development.

Recently, Dezhou Hua Fu Ecological Technology Co., Ltd., a wholly-owned subsidiary of Dezhou Huayuan, passed the audit of Heinstein Company in Germany and obtained the certification of sustainable textile production (STeP) issued by OEKO-TEX. The certification passed the module evaluation in six related fields, especially in the modules of social responsibility, occupational health and safety and quality management, which further affirmed the efforts and commitments made by Dezhou Huayuan in the fields of responsible production management and sustainable development.

Under the trend of the times that the concept of sustainable development has been deeply rooted in people's hearts and the textile industry has been transformed and upgraded, Dezhou Huayuan has established the concept of "differentiation+"with the guidance of green textile, and determined the development vision with the goal of creating differentiated yarn precision service providers. Through equipment technology upgrading and management innovation, the modern enterprise system has been established and the modern management level has been improved. Has passed the FSC, GRS, ISO900 1, ISO 1400 1, OCS, GOTS, STeP certification, Decathlon Group, Inditex Group B supplier certification. Products follow the concept of "green, science and technology, fashion", choose green fiber raw materials, and produce differentiated products with environmental protection, safety and fashion through new spinning process innovation, develop green textiles and help circular economy.

Li Yubin, executive deputy general manager of Dezhou Huayuan, introduced that the eco-magic cellulose yarn series produced by the company subverts the traditional innovative way, and meets the needs of contemporary consumers for the sustainable concept with the product concept of salt-free and alkali-free dyeing, low-carbon environmental protection and quick response. TENCEL E+, a regenerated cellulose product exclusively authorized by Austrian Blue Crystal Group, is not only environmentally friendly, but also skin-friendly, durable and comfortable, with more expressive and stable colors.

Develop differentiated products of health concept

With the outbreak of COVID-19 epidemic in 2020, consumers are no longer simply satisfied with dressing up beautifully, but also require to wear healthy clothes. Antibacterial functional textiles have become the development focus of textile enterprises.

According to this demand, Weiqiao Textile Co., Ltd. (hereinafter referred to as "Weiqiao Textile") has developed a series of yarns such as permanent antibacterial cotton yarn, Ivey antibacterial yarn, mint antibacterial yarn, pure cotton antibacterial elastic yarn, Antaibei antibacterial yarn and antibacterial fabrics made from these yarns.

The person in charge of textile products in Wei Qiao said that the research and development of every product requires unremitting efforts and the joint efforts of all departments and production units. Sometimes a research and development takes several years, and research, interviews, communication and trial production are also needed. "Enterprises must have their own competitive advantages, and this advantage is dynamic. They must keep up with or perceive people's consumption needs in advance, especially their inner needs in spiritual, psychological and cultural connotations. " The person in charge of Wei Qiao Textile Technology R&D Center said.

In order to meet the market demand for antibacterial and environmental protection, Dezhou Huayuan has launched a variety of differentiated fiber products with health concepts, such as diacetic acid series, seaweed fiber series, super antibacterial series, plant dyeing series, skin-beautifying velvet series, recycled polyester series and degradable polyester.

Li Yubin said that unlike a large number of one-to-one customized development in previous years, this year Dezhou Huayuan not only paid attention to the differentiation and quality improvement of new products, but also paid attention to market orientation and quantitative reserve supply. By adopting the "order+stocking mode", the company accurately grasps the market direction, fully meets the brand demand, and improves the differentiated products in series and in batches around the preferences of users, further enhancing the company's rapid response capability.

Innovating energy-saving technology and practicing green production

In recent years, textile enterprises not only pay attention to product research and development, but also pay attention to process innovation and optimization. Especially for textile enterprises with dyeing and finishing links, there is still a long way to go to innovate energy-saving technologies and realize green production in the whole process.

Kaiping Benda Textile Co., Ltd. is a textile enterprise integrating spinning, weaving, dyeing and printing. Recently, three technologies used in its innovative research and development were selected into the Catalogue of Energy Saving and Emission Reduction Technologies and Innovative Applications in China Cotton Textile Industry issued by China Cotton Textile Industry Association.

Different from the conventional dyeing method of colored denim fabrics, the water-free dyeing environment-friendly colored denim fabrics innovatively developed by Kaiping Benda Textile Co., Ltd. have been reformed, which overcomes the shortcomings of traditional dyeing, such as consuming a lot of water, electricity, steam, incomplete chromatography, thick but not bright color, not resistant to bleaching and fragile storage. The warp yarn is dyed by a new coating spray dyeing technology. The dyeing process does not need strong corrosive additives such as water and sodium sulfide, and there is zero emission after dyeing. The new process carries out special pretreatment on white warp yarn, which improves the dyeing efficiency by more than 15%, increases the rubbing fastness improver, and improves the color fastness to dry and wet rubbing.

Kaiping Benda Textile Co., Ltd. has optimized the boiling and bleaching process of corduroy, scientifically reduced one steaming process and one washing process on the original process, and the process is efficient and short, which can not only meet customer requirements, but also reduce the consumption of water, electricity, steam energy and manpower. After transformation, the energy saving rate is about 20%, and the emission reduction rate is about 10%.

With the increase of small batch and multi-variety orders, the processing difficulty of dyeing also increases. In order to reduce the processing cost, Kaiping Benda Textile Co., Ltd. carried out technological innovation and developed the two-dip and one-roll process of setting machine. The padding groove is added to the original padding groove of the setting machine, so that the fabric is padded twice before setting, which improves the color fastness and other properties of the fabric, and enables a piece of cloth to achieve the required effect without twice setting processing. After the transformation, the energy saving and emission reduction rate is about 50%, and the investment payback period is about half a year.
