China'S Chemical Fiber Production Accounts For 70% Of The World'S Textile Recovery But Less Than 10%.

With the improvement of people's consumption level and the popularity of "fast fashion", the waste problem of waste chemical fiber textile is increasingly prominent.

The regeneration cycle of chemical fiber textiles is an urgent demand for the development of China's textile industry.

The Research Report of the Chinese Academy of engineering points out that in the future, we should build a recycling logistics system guided by "zero abandonment, clean carbon, high quality and high value", build a recycling and recycling industrial agglomeration and demonstration park, and build an innovation and exhibition platform for production, study and research, so as to get rid of the waste chemical fiber textile recycling channel.

Where did your old clothes go? Were they discarded at will or sent to the clothes recycling bin? According to the China Federation of textile industry, if China's waste textiles can be recycled, it will save 24 million tons of crude oil a year, save nearly 1/3 of cotton planting area, and reduce 80 million tons of carbon dioxide emissions.

The Chinese Academy of Engineering Consultative research project "the development strategy research on recycling technology of waste chemical fiber and textile resources" was held in Beijing recently. Based on the deep combing and comparing the status quo and development trend of recycling and recycling of waste chemical fiber and textile resources at home and abroad, the research report put forward the key task of recycling and recycling of waste textile fiber resources in China, and clarified the development direction of the whole industry chain technology system.

China is the world's largest producer and application of chemical fiber. In 2016, the total output of chemical fiber reached 49 million 440 thousand tons, accounting for 69.4% of the total chemical fiber in the world.

The total processing capacity is 54 million 200 thousand tons, of which chemical fiber accounts for 84.23%, and occupies the leading position.

With the rapid development of the industry and the rapid increase of consumption, the disposal of waste chemical fiber textiles is also following.

It is estimated that by the end of the "13th Five-Year" period, the output of China's waste chemical fiber textiles can reach nearly two hundred million tons, but the recovery rate of textiles in China is less than 10%, which is much more obvious than that in developed countries.

Waste chemical fiber textiles are treated as garbage for landfill or incineration, which not only pollute the environment seriously, but also cause great waste of resources.

Seeking recycling and recycling has become an urgent need for the development of China's textile industry.

According to Jiang Shicheng, academician of the Chinese Academy of engineering, in order to promote the sound development and comprehensive upgrading of China's chemical fiber recycling industry, the Chinese Academy of engineering set up a consultation project on the development strategy research of recycling technology of waste chemical fiber and textiles in 2017. It was led by academicians in the textile field, relying on Donghua University, and invited more than 40 experts from colleges and universities and representative enterprises to participate in the research.

It took more than a year to form research reports and academician suggestions.

"Chemical fiber recycling cycle is

The important direction of the industry in the new era.

Wang Huaping, Secretary General of the project, said that in the next 10 years, with the goal of "zero abandonment, clean, low carbon, high quality and high value", and taking the construction of major science and technology projects as the starting point, and with the construction of independent innovation system based on the combination of "politics, production, learning, research and application", a national textile recycling cycle scientific research and engineering technology development platform will be set up, so that the recycling technology and innovation ability of China's polyester, polyamide, polypropylene, polyphenylene sulfide and other key chemical fiber varieties will be among the highest in the world.

On this basis, the project has put forward key tasks.

One is the research on the basic science of regeneration of waste chemical fiber materials; the two is the rapid identification and sorting technology of waste chemical fiber textiles; the three is the pretreatment and resource standardization of waste chemical fiber textiles; four is the key technology and industrial upgrading of mechanical and physical regeneration, five is the key technology and industrialization of physical chemical regeneration, and the six is the key technology and industrialization of chemical regeneration.

At the same time, the project forms 3 special recommendations.

First, we should build a modern recycling logistics system for waste textiles.

Under the coordination of the relevant state departments, the local government and professional structure should be combined to set up a list of waste textile logistics technology and equipment procurement. With the form of special government subsidies, a chain of reclaimed logistics of waste chemical fiber textiles will be formed with complete system, complete functions and orderly management and operation. Based on the construction of modern recycling logistics information platform, the intelligent recycling box, specialized logistics vehicle and distribution management station will be constructed in a progressive way, and a 200 km recycling economic circle will be built to achieve the full coverage of the recycling logistics network system.

Second, we should build a recycling industrial cluster and demonstration garden for waste chemical fiber textiles.

We should make full use of the synergy and scale effect, optimize the allocation of resources, improve the efficiency of resource utilization, and form a combination of dots, dots and surfaces to form a radiant drive to promote the recycling of waste chemical fiber textile industry to achieve rapid development.

Third, we should build innovation and display platform for waste chemical fiber textiles.

It is suggested that the state set up special national key laboratory for recycling of waste textiles and national engineering and technology research center, strengthen research and talent platform construction, speed up the basic research of chemical fiber regeneration and the pformation of research results.
