Abstract
The invention discloses a primary treatment process of a pallet produced by utilizing waste and old textiles. A preparation method of the primary treatment process comprises the following steps of using recycled waste and old textiles as a raw material, washing the recycled waste and old textiles, and fluorescently disinfecting the washed waste and old textiles, thus obtaining fiber fragments of the waste and old textiles; heating thermoplastic resin to be fused; sending the fiber fragments of the waste and old textiles into an agitating machine, and adding a powdery thermoplastic resin film into the agitating machine; adding an adhesion agent into the agitating machine, and sufficiently mixing the fiber fragments of the waste and old textiles with the adhesion agent; shaping a material through a mold to obtain a primary fiber solidified plate of the waste and old textiles, and injecting the fused thermoplastic resin in the primary fiber solidified plate. According to the primary treatment process of the pallet produced by utilizing the waste and old textiles, through the waste and old textiles subjected to surface treatment, surface energy can be increased; the surface roughness of the waste and old textiles is increased; therefore, the prosperities of the wetting, the adhesion and the like of the surfaces of the waste and old textiles are increased; the interface bonding among the waste and old textiles and matrix resin are obviously improved and enhanced; an interface layer can effectively transfer a load.
Description
Technical field
The present invention relates to a kind of sheet material production technical field, particularly relate to a kind of supporting plate preliminary treatment technique utilizing waste textile to produce.
Background technology
Waste textile includes waste and old natural cotton fiber and chemical fibre, is the most all as garbage disposal, and the simplest mode of process is burned exactly, easy contaminated air, in addition it is also necessary to a no small processing cost.
The comprehensive utilization of waste textile, as the novel style of economic increase of a kind of cotton textile industry, the most in the field of business has obtained 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.The development of industry is organically combined with environmental conservation, realizes the radical change of industry growth pattern, alleviate economic growth and shortage of resources, the contradiction of environmental conservation, promote the sustainable development of industry.But cotton textile industry waste textile present situation: " comprehensive utilization of waste textile is the gold mine that textile industry is to be dug " Chinese textile industry community deputy chairman height is bravely so pointed out, " the fiber process amount of China in 2014 reaches 50,000,000 tons, wherein consumes the most at home for more than 2,000 ten thousand tons.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, the output of cotton that we are annual can be exceeded.”
Cotton textile industry waste textile mainly has two sources, and one is the solid fiber waste material produced in process of textile production, and 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.The first white paper about waste textile recycling economy present situation of China " 2014/2015 China's waste textile recycle and reuse research report " shows, within 2013, China has produced the waste textile society storage of about 2007.3 ten thousand tons, and wherein cotton fiber accounts for 5,620,000 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 waste textile utilizes industry.
China's waste and old weaving system development is the most perfect, has focused largely on enterprises limit yarn, hard waste, cloth, cloth etc. and recycles.2013, Chinese textile industry community " duds zero is abandoned " organized is movable to be started, and is currently also the carrying out of little scope in some areas, carries out in China and need time.
" the innovative Cotton Textile Enterprises of energy-saving and emission-reduction in 2014 " Wei Qiao Textile Co., Ltd., Changle of Fujian Province Chang Yuan Textile Co., Ltd. make progress at aspects such as reclaiming limit yarn, hard waste, cloth, cloth.By purchasing the equipment such as carding machine, lapper, opener, centrifugal dehydrator, or existing equipment is reasonably transformed, by the waste cotton of recovery, limit yarn, hard waste, cloth etc. through picking, by soft silk, the slurry classification of type such as silk, cloth, feature according to different waste materials, respectively slurry silk, cloth pretreatment are become soft thread state, be then passed through cutting again, shredding, fibre-condensing, rolling, comb and parallel cotton fibers prior to spinning, dedusting, the operation such as packing, it is achieved to noil, waste and old limit yarn, the comprehensive cyclic utilization of selvedge.
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.
The fiber produced after cut-out just can realize recycling through operations such as undue comb, long and short fiber separation again.Long fibre utilizes as regenerated fiber, and chopped fiber can be as non-woven fabrics, construction material etc..
But cotton textile industry waste textile utilizes development existing problems, and waste textile comprehensively recycles and the most really forms industrialization, overwhelming majority waste textile is not comprehensively utilized.Have is exactly that to become the production cost of regenerated resources higher for waste textile again.At present, the production cost of regenerated fiber is 1.2 times of protofibre.Owing to the production cost of regenerated fiber is higher than protofibre, to such an extent as to down-stream enterprise is the highest to the demand enthusiasm of this reconstituted product；It addition, waste textile equipment investment appropriate litigation fees is high, the waste and old product bedding and clothing recycling equipment infusion of financial resources of China's independent research reaches more than 300 ten thousand yuan.
If waste and old textile can be recycled, not only save energy resource consumption, it is thus also avoided that substantial amounts of waste textile is as garbage environment pollution.The composition of waste textile in the market is complex, and the fiber of composition is of all kinds, and the outer market of Now Domestic is seldom seen to recycle waste textile and produced the product produced.
Summary of the invention
