Background technology

Waste textile includes waste and old natural cotton fiber and chemical fibre, is the most all as garbage disposal, processes Simplest mode burn exactly, easy contaminated air, in addition it is also necessary to a no small processing cost.

The comprehensive utilization of waste textile is as the novel style of economic increase of a kind of cotton textile industry, in industry Inside obtain the biggest attention.The comprehensive utilization of waste textile is that cotton textile industry realizes developing a circular economy, The effective approach of one of Resources for construction economizing type and friendly environment society.By development and the environment of industry Protection organically combines, and realizes the radical change of industry growth pattern, alleviates economic growth and protects with shortage of resources, environment The contradiction protected, promotes the sustainable development of industry.But cotton textile industry waste textile present situation: " waste and old spin The comprehensive utilization of fabric is the gold mine that textile industry is to be dug " Chinese textile industry community deputy chairman height is the most so Pointing out, " the fiber process amount of China in 2014 reaches 50,000,000 tons, and wherein more than 2,000 ten thousand tons the most at home Consumption.According to depreciation rough calculation in general 3 to 5 years, the amount of annual waste textile was at 500 ten thousand to 1,000 ten thousand tons. If these waste and old fibres are re-used, can be exceeded us annualCotton GossypiiYield.”

Cotton textile industry waste textile mainly has two sources, and one is under the solid produced in process of textile production Foot fibrous material, this is comprehensively utilized in every field by various modes in current textile enterprise produces. Two is clothing, the household textiles being no longer used in consumer field.China is first to be circulated about waste textile White paper " the 2014/2015 China's waste textile recycle and reuse research report " display of economic phenomena, Within 2013, China has produced the waste textile society storage of about 2007.3 ten thousand tons, and wherein cotton fiber accounts for 562 Ten thousand tons.And China's waste textile reuse ratio is less than 10%, have a long way to go with advanced level, it would be highly desirable to development is useless Old textile utilizes industry.

The development of China waste and old weaving system is the most perfect, have focused largely on enterprises limit yarn, hard waste, cloth, Cloths etc. recycle.2013, Chinese textile industry community " duds zero is abandoned " organized is movable Start, be currently also the carrying out of little scope in some areas, carry out in China and need time.

" the innovative Cotton Textile Enterprises of energy-saving and emission-reduction in 2014 " Wei Qiao Textile Co., Ltd., the long source of Changle of Fujian Province Textile Co., Ltd. makes progress at aspects such as reclaiming limit yarn, hard waste, cloth, cloth.By purchase carding machine, The equipment such as lapper, opener, centrifugal dehydrator, or existing equipment is reasonably transformed, will reclaim Waste cotton, limit yarn, hard waste, cloth etc. through picking, by soft silk, the slurry classification of type such as silk, cloth, according to The feature of different waste materials, becomes soft thread state by slurry silk, cloth pretreatment respectively, be then passed through cutting again, shredding, The operations such as fibre-condensing, rolling, comb and parallel cotton fibers prior to spinning, dedusting, packing, it is achieved to noil, waste and old limit yarn, comprehensively the following of selvedge Ring utilizes.

Recently, hold on-the-spot meeting in Henan by the old product recycling equipment of China's independent research, by checking and accepting. First the waste textiles such as clothes can be cut to fragment by this equipment, are then passed through air-suction duct entrance de-burring machine and remove The foreign material such as button, slide fastener, enter baling press and pack.Finally, then through tearing shredding single yarn Carded fiber.This complete equipment can process duds 1 ton per hour.
