Research And Product Development Of Regenerated Silk Wool Blended Yarn And Fabric

China is a big country in textile and clothing.According to statistics,the annual consumption of textile fiber in China is more than 45 million tons.Due to the shortage of resources,the annual need to import large quantities of textile raw materials,waste textiles by appropriate methods to achieve recycling,will be able to create a large number of regenerated textile raw materials,waste textiles achieve economic value,ease the resource constraints and other issues of raw materials.At present,most of the waste textiles in our country can not be effectively recycled and reused,resulting in huge waste of waste textiles,or being burned or buried.The recycling of waste textiles can greatly reduce the emission of harmful gases and reduce carbon emissions,which has an extremely important social and environmental significance.This paper,starting with waste silk and waste wool textiles,studied the high value-added recycling of waste natural protein wool and silk fiber.First,the waste textiles are sterilized efficiently,and then they are sorted quickly and sorted according to the ingredients of the waste textiles,so as to get the waste wool and silk textiles.Then,through the mechanical loosening method,the waste textiles can be loosened into fibrous raw materials,and the regenerated protein fiber can be used for spinning and reproducing protein fibers for spinning and weaving,and is used for the preparation of recycled garment fabrics.It can not be used for spinning raw materials for making high-grade carpet raw materials.The specific research contents are as follows:1、Research on the rapid disinfection technology of waste silk and wool fiber.Because of the high efficiency of ultraviolet disinfection and sterilization,the safe and reliable operation efficiency and no two pollution.In order to combine the ecological environment concept of this subject,the ultraviolet disinfection method was chosen to disinfect the waste silk wool fabric.2 、Using the waste clothing sorting system of Valvan company,using the near infrared spectroscopy analysis technology,according to the waste textile The composition of the material is different,the wool and the silk waste textile can be automatedand accurate sorting,the sorting efficiency can reach 540 kg/h.3 、 The Italy imported DELL ’ORCO & VILLANI opening line,through mechanical processing,for without waste wool cloth,dyed cloth piece,wire cutting,colorless sheet and tear open loose,fine opening and other physical processes,waste wool directly re processing,to obtain regeneration wool fiber.The suitable spinning process is selected to obtain the regenerated silk / wool blended yarn that meets the requirements of the machine.Through the rational allocation of waste silk and recycled wool fiber blended ratio,optimization and Mao process,and the crude oil concentration is controlled at about 20%,and reduce the static and dynamic friction between fiber and fiber and metal fiber;carding machine control on moisture regain at25~27% between,the carding process can be carried out smoothly;finally through the regenerated silk the fracture / ring spun wool blended yarn strength and elongation is good,can satisfy the requirements of the machine.4、Through the study of silk wool blended fabric dyeing performance obtained with a light colored silk / wool blended products,using one bath two step process;deep dyed silk / wool blended products,using two bath method,were used to approximate conditions of single dye on silk / wool blended fabric dyeing can be obtained good dyeing of the same color and color fastness.5、Due to the poor performance of the regenerated silk / wool blended fabric to resist the pilling,the processing technology is finished after a reasonable design.It can reduce the damage of the mechanical properties of the fabric and improve the ability to resist the pilling and pilling of the regenerated silk / wool blended fabric.The research and analysis of this subject can provide a certain reference for the follow-up researchers to study the high additional comprehensive utilization of waste textiles.The reference significance is of great practical significance to the comprehensive utilization of the high added value of the waste textiles.
