Investigation On Comprehensive Utilization Of Waste Textiles

Here in the world clothing shoes The small knitting of hat net introduces the waste spin Investigation on current situation of comprehensive utilization of products.

Waste textiles can be divided into waste and used textiles. The source of waste textiles is mostly the leftovers and waste materials generated during the production of textile mills. A small part of such textiles are digested by enterprises themselves, and most of them are recycled by specialized agencies. 90% of the waste materials can be recycled, basically eating and squeezing out. The source of used textiles is mostly used clothing, home textile products, etc. This part of textiles is large in quantity and not recycled by professional institutions. Most of them are stored in consumers' homes, causing waste of resources and becoming "encumbrances" in people's homes. How to turn these "encumbrances" into treasures is the common responsibility of enterprises, industries and society. At present, the recycling of waste textiles in China is still in the primary stage. Although some enterprises have done well, there are still some problems and difficulties in the whole industry. This issue discusses the current status, problems and difficulties of recycling of waste textiles.

　　 Waste

The leftovers produced by the source textile mill in the production process represent the enterprises Zhejiang Jiaren New Material Co., Ltd., Wenzhou Tiancheng Textile Co., Ltd., and Wenlong Group Co., Ltd. The enterprises with problems in recycling are small in scale, lack of leading enterprises, and produce products with low added value in the recycling industry. At present, the waste generated in the production process of textile mills in China has basically been recycled. Where is the recycled waste used?

It is reported that enterprises need to recycle and reuse to produce new products after physical or chemical treatment, most of which are used in cleaning products, automobile accessories, construction engineering, packaging materials, protective facilities and other fields. Secretary General of the Strategic Alliance for Technological Innovation of Waste Textile Comprehensive Utilization Industry

Wang Shuwen said that the waste recovered by ordinary enterprises will be classified, processed and reused according to different textures and colors. For example, Cangnan, Wenzhou, is a region where the recycling of waste textiles is concentrated in China. Local enterprises mainly recycle cotton and chemical fiber waste, and then smash these waste materials

After loosening treatment, the mop, non-woven fabric, roadbed cloth and other products are made. With the expansion of scale, Cangnan has a relatively complete industrial chain from scrap management, renewable fiber processing to rotor spinning. At present, there are more than 2000 renewable fiber production enterprises in the county

The material throughput is more than 3 million tons, accounting for more than 80% of the country. Part of the yarn is hand woven into pet toys, mops and other products, which are exported to Europe, America, Japan and Russia.

At present, Wenzhou Tiancheng Textile Co., Ltd., a leading enterprise in Cangnan County, has an annual output of 15000 tons of recycled yarn project and Wenlong Group Co., Ltd. has an annual output of 30000 tons of differential polyester staple fiber project, which have been approved by the National Development and Reform Commission and received relevant financial support. However, in Cangnan, enterprises like this can be found

According to Lin Ting, the sales manager of Cangnan Jixing Material Recycling Company, the waste textile recycling industry has a low starting point and low investment. Many local residents are slowly making use of a little money. Therefore, Cangnan's waste textile recycling industry is also facing planning and layout

Confusion, low, small and scattered industry, difficulty in implementing environmental protection measures, large potential safety hazards and other problems.

Wang Shuwen said that in addition to Cangnan, the recycling of waste textiles in Nanxun District of Huzhou has basically formed a recycling industrial chain of recycling sorting processing (cotton opening, yarn opening) sales (utilization). There are nearly 700 textile enterprises in the region, a professional wool textile raw material trading market, and wool textile raw materials

The annual trading volume is more than 200000 tons. The main waste products are chemical fiber, wool and cashmere, which are leftovers and waste materials from knitting mills and sweater factories.

The recycling of waste textiles mentioned above basically adopts physical technology, which is also a common practice in China. Chemical technology treatment has high requirements on capital and technology of enterprises. It is the first enterprise in China to use chemical method to produce recycled fiber

Zhejiang Jiaren New Material Co., Ltd. is a joint venture jointly invested by Seiko Holding Group and Teijin Group. The enterprise has the most cutting-edge technology of decomposing polyester products into raw materials at the molecular level and then making polyester fibers. Obtained from decomposition at molecular level

Although the price of renewable materials is expensive, compared with the use of petroleum to manufacture polyester raw materials, energy consumption and carbon dioxide emissions can be reduced by up to 80%. Jiang Longchun, the assistant general manager of the company, said, "At present, the enterprise mainly uses the leftovers produced in the production of textile mills. The next step is to expand the old ones

For the recycling business of clothing products, the company has organized enterprises that want to participate in the recycling plan together and established an 'ECOCIRCLE' organization. The agency cooperates with cooperative enterprises from the commodity development stage to recycle old products in physical stores clothes And then made into recycled fiber for sale

It will be remanufactured into textiles for enterprises participating in the cooperation. There are more than 150 enterprises participating in the plan, including those providing cooperation in tooling recycling, but there are only two sportswear manufacturers in China. "

　　 used

Sources of waste textiles, such as old clothing, home textile products, interior decoration, etc. Recycling representative enterprises Shanghai Yuanyuan Industrial Co., Ltd. Use representative enterprises Guangde Tianyun Nonwoven Co., Ltd., Gaoqing Feihong Woolen Textile Co., Ltd. There are problems and lack of formal recycling channels There is still a lack of recycling channels for large enterprises. The destination of recycled old textiles mainly includes individuals and enterprises. Individuals refer to the clothes and home textile products that have been recycled and donated to people in need after cleaning and disinfection. The enterprise refers to the recycling of old textiles and the production of new products for use in various fields after physical or chemical treatment. Unlike the recycling of waste textiles, most of the old textiles are stored in people's homes, which is large in quantity and scattered, making it difficult to recycle. In addition, there is no special channel to deal with such textiles in China at present, so there is still much room for the recycling of such textiles.

At present, there is no mature channel to collect such textiles stored in people's homes, mainly through Brand clothing The store may set up recycling bins in the community to collect. Shanghai Yuanyuan Industrial Co., Ltd. is the only enterprise qualified to recycle waste clothing in China. Yang Yihong, the general manager of the company, said: "At present, there are three channels for the company to recycle used textiles: first, 1500 recycling bins have been set up in schools and communities; second, with the support of the Shanghai Municipal Government, dozens of tons of old clothes can be received at the event site through the promotion of recycling activities of waste textiles by enterprises and units; third, the company telephone number is announced through various channels to provide door-to-door clothing service. About 150 tons of used textiles are recycled every month, 80% of which are sold to processing enterprises and used in various fields after processing. "

Gaoqing Feihong Woolen Textile Co., Ltd., as a downstream enterprise of Shanghai Yuanyuan Industrial Co., Ltd., mainly uses old woolen textiles as production materials. Due to the lack of technical equipment for waste textile sorting in China, the company still adopts manual sorting method for sorting. In the production process, ring spinning and rotor spinning are combined. At present, the company recycles 700 tons of waste raw materials every year, with an annual output of 640 tons of yarn, and the utilization rate reaches more than 90%. The company exports fabrics made of yarn to the United States, Russia and other countries.

Different from Feihong Wool Textile Company, Guangde Tianyun Nonwovens Co., Ltd. has its own clothing recycling outlets, which are mainly targeted at citizens, and a few outlets will purchase fiber waste from factories; The other part is recycling waste textiles through small traders. According to Zhu Lian, the general manager of the company, the company now produces sound insulation materials for automobiles and household appliances from recycled chemical fiber clothing and cotton textile clothing through physical technology. In 2013, the company developed new products of environment-friendly cotton fiber board. At present, the company has built two production lines for comprehensive utilization of waste clothing (each subsidiary has built an independent production line), with an annual comprehensive utilization of 8500 tons of waste clothing, an annual production of 4 million square meters of sound insulation pads, 300000 sets of car interiors, and two series of products of more than 80 varieties.

　 Industry perspective

Broad prospects and difficulties

Although the recycling of waste textiles has a broad prospect, it is undeniable that there are still many obstacles to industrial development. Enterprises engaged in the recycling of waste textiles generally have the characteristics of low product grade, low added value and disorderly competition; The enterprise is small in scale and distributed dispersedly

Forming industrial clusters and recycling enterprises fighting independently; There is no backbone enterprise involved. At present, there is no large-scale leading enterprise engaged in large-scale, high value-added recycling.

——Wang Shuwen, Secretary General of the Strategic Alliance for Technological Innovation of Waste Textile Comprehensive Utilization Industry

　 Emerging industries should receive more support from the state

First of all, the state should also give strong support in policy. As an emerging industry, waste textile recycling has initially formed an industrial chain, but for individuals, textile recycling needs to purchase equipment and introduce talents, which will occupy a lot of funds. Therefore, if there is no national policy support, most enterprises and individuals are not enthusiastic about recycling waste textiles.

Secondly, the recycling of waste textiles needs to be standardized. As we all know, waste textiles are mixed with a variety of fibers, and their uses after treatment are different. At present, there are four directions: first, full resource utilization; Second, return to spinning and weaving; Third, nonwovens are made by bonding, needling and other methods for industrial textiles; Fourth, it is used for export. Standards and relevant laws and regulations are required to restrict and guide the recovery, production and utilization of waste textile recycling enterprises. ——Zhu Lian, General Manager of Guangde Tianyun Nonwoven Co., Ltd

Formal channels need to be established

At present, most of the practitioners of waste textile recycling in China are self-employed, while few formal recycling enterprises are led by the government. The main channels of used clothing recycling are private recycling and site recycling. At present, enterprises also mainly use the leftovers produced in the production of textile mills. The next step is to expand the recycling business of used clothing products. The company hopes to cooperate with brand enterprises from the commodity development stage, recycle old clothes in physical stores, and then make recycled fibers for sale to participating enterprises, Remanufactured as textile 。
