Analysis Of The Current Situation Of Domestic Textile Recycling And Recycling -- Taking Chemical Fiber Materials As An Example

< p > according to the relevant data, during the "12th Five-Year" period, China's "a target=" _blank "href=" //www.sjfzxm.com/ "> strong" textile > /strong > /a > consumption will increase by more than 12%. At the end of 12th Five-Year, the total volume of waste textiles will exceed 1.4 billion tons, of which 98 million tons of chemical fiber and 42 million tons of natural fiber. At present, most of the waste textiles have not been comprehensively utilized. < /p >
< p > waste textiles mainly come from two links: first, production links, such as cotton mill's noil, textile mill's waste silk, waste material of chemical fiber factory, waste material of printing and dyeing factory, < a target= "_blank" href= "//www.sjfzxm.com/" > strong > clothing < /strong > < a > factory corner, a target= "a", "target=", "cloth >", "etc.", and "consumption", such as waste clothing and household textiles, which are eliminated after the service life cycle. Because industrial textiles are mainly used in the fields of medical treatment, construction, filter materials and so on, they are generally not recyclable, but the waste yarn of cotton spinning and weaving factories can directly be used as textile raw materials, and most of them are directly reused in factories. Therefore, the main sources of waste textiles are waste silk, waste silk, waste cloth and leftover materials, obsolete clothing and household textiles, such as chemical fiber factories, weaving factories, printing and dyeing factories and garment factories. < /p >
< p > because some key technical bottlenecks of waste textile recycling have been conquered, the quality of recycled products has been greatly improved, and the market of recycled raw materials is excellent. Vigorously developing the comprehensive utilization of waste textiles can not only save a lot of textile raw materials, but also bring about high economic benefits. Moreover, it can greatly alleviate the shortage of oil resources and the competition for cotton and grain. < /p >
< p > with the continuous progress of regeneration technology, the physical properties of recycled raw materials will be greatly improved, and its application areas will continue to expand. Recycled raw materials are expected to be widely used in construction, agriculture, automotive noise insulation materials and other industrial textiles and household textiles, resulting in great economic benefits. However, China's waste textile recycling industry has the following problems: < /p >
< p > one is the general characteristics of low, small and scattered. "Low" refers to the low grade and low added value of regenerated products. "Small" refers to the small scale of enterprises, which have always been individual businesses and have not formed scale. Two, there is no industrial cluster, and every recycling enterprise is fighting for itself. Zhejiang, Cixi, Cangnan and other places have formed waste textiles concentrated, but no competent departments have taken the lead in establishing a standardized, orderly and regional distribution center to regulate the trading behavior of the industry. Three, there is no backbone enterprises to participate. Enterprises engaged in the recovery and utilization of waste textiles are generally small private enterprises, or a part of the textile enterprises involved in small-scale recycling, for their own production and use. At present, there is not a large leading enterprise engaged in large-scale, high-value and resourceful recycling. < /p >
"P > China's Textile Industry Federation, China Resources Comprehensive Utilization Association and General Logistics Department Quartermaster Equipment Research Institute jointly launched field research in 2010~2012. It shows that recycling and reuse of waste textiles in China has formed an objective industrial chain across the country. To understand and analyze its industrial status and development trend is of great significance to the construction of a complete circular economy system in the textile industry. {page_break} < /p >
< p > over the past 30 years, the scale of the comprehensive utilization of China's textile industry has gradually expanded. Among them, polyester bottles and waste textiles are the largest two types of renewable resources utilized by the textile industry. By 2010, China's regenerated polyester industry has developed into a scale industry with capacity exceeding 7 million tons / year and output exceeding 5 million tons / year. Since the birth of domestic PET bottles, the social stock accumulation of PET bottles has exceeded 25 million tons in China. The social reserves of waste textiles are even more alarming. China's annual total 2/3 of fiber processing is used for domestic demand. < /p >
< p > it is understood that in the 70s of last century, DuPont Co successfully developed PET bottles and entered the market. Before and after 80s, China began to produce polyester bottles on its own. It is estimated that since the birth of domestic PET bottles, the social stock accumulation of China's pet bottles has exceeded 25 million tons. The social reserves of waste textiles are even more alarming. China's annual total 2/3 of fiber processing is used for domestic demand. Over time, a large number of waste textiles precipitated in the society have evolved into solid wastes, and the stock is estimated to be 23 million tons / year. < /p >
< p > according to the statistics of the regenerated chemical fiber Specialized Committee of the chemical fiber Association and the investigation and research team, it is estimated that the amount of these two recycled resources used in China's textile industry in 2011 is 5 million 470 thousand tons of bottle flakes and 3 million 380 thousand tons of waste textiles. The used PET bottles account for about 9% of the social stock, and the used textiles account for about 14% of the annual social stock. < /p >
< p > 2011, China's recycled polyester industry imported bottles 1 million 670 thousand tons, made in China and recovered 2 million 800 thousand tons, the total amount of recycled PET bottles was 4 million 470 thousand tons. For China's regenerated polyester industry, raw materials other than polyester bottle chips also use industrial waste polyester and waste polyester textiles. In 2011, about 300 thousand tons of industrial waste polyester and 1 million tons of waste polyester textiles were used. As far as China's polyester and polyester industry is concerned, since the birth of polyester in 1964, it has produced 2.1 million tons of polyester and 1.85 billion tons of polyester in 2010. According to the consumption of five years, the total social stock of these polymers is close to 4 billion tons. < /p >
< p > after the rapid development of "11th Five-Year", the industry status of regenerated polyester industry has changed from "supplement" to "substitution". However, the shortage of raw material supply has become increasingly prominent. During the "11th Five-Year" period, the regenerated polyester industry has been listed as one of the industries that focus on developing circular economy. At present, it has formed a good, standardized and orderly production, operation and sales mode, and has also formed a relatively obvious industrial comparative advantage. However, the connotation of product differentiation rate needs to be improved. Besides, the shortage of raw materials has become a bottleneck for further development of recycled polyester industry. < /p >
< p > in fact, only for polyester and polyester industry in China, polyester was born in 1964 and produced 2.1 million tons of polyester and 1.85 billion tons of polyester in 2010. According to the consumption of 5 years, the total social stock of these polymers is close to 4 billion tons. Most of them exist in the form of "textiles" or "a target=" _blank "href=" //www.sjfzxm.com/ "> strong > dress < /strong > /a >. Because of the complicated process and many accessories, the textile has no effective recycling equipment and technology. If we can solve these problems of solid waste recycling, on the one hand, we can provide raw materials for recycled polyester industry, on the one hand, we can reduce environmental burdens. < /p >
