Strand combining polyester filament yarn with cooling function

Abstract

The invention discloses a plied polyester filament with the cooling function. The spinning selects sub-nanometer ZnO as the main functional additive, the adding amount of which is 3 percent-5 percent; the conventional polyester manufacturing process is adjusted and optimized; the injection method is adopted to add the additive into polyester melt, so as to prepare POY; then the texturing adopts the 'S plus Z' ply manner to process the POY into a untwist plied product, thereby obtaining the polyester filament with bacterium inhibition, cooling, skin care and health care functions; at the same time, the product with the advantages of softness, chubbiness, strong filament bundle standing performance, etc., is applicable to the processing of undergarments such as underwear, sports suits, bathrobes, etc.

Description

technical field [0001] The invention relates to a polymer fiber, in particular to a plied polyester filament with cool function. Background technique [0002] In the past 10 years, the global high-tech textile market has been rising rapidly, with an annual growth rate of about 4.8%, among which the growth rate of the Asian market is even greater. In the field of high-tech textiles, polyester has always occupied a large market share, and the demand is very strong. However, compared with foreign developed countries, there is still a large gap in domestic technology and product variety structure, mainly manifested in prominent structural contradictions, unbalanced industrial chain development, excess production capacity of conventional products, poor new product development capabilities, and lagging behind in high-tech original technologies , the differentiation rate of chemical fiber is only about 30%, far lower than the 45-50% in developed countries. At the same time, becau...

Problems solved by technology

At present, the popular cycle of functional products is getting shorter and shorter, which means that the cycle of differentiated products is gradually shortened, the requirements for fibers are getting higher and higher, and the flow of talents, technology, and information is smoother, and the market feedback is rapid. Any product As long as it appears, there will soon be a large number of similar products in the market, thus losing high added value, so companies need to continuously develop new products to cope with the market
