Embodiment 1

[0031] The manufacture of embodiment 1 ultra-fine anisotropic composite stretching fiber

[0032] After drying conventional polyester chips (amount of 100%) at a temperature of 120°C for 25 hours, add flow stabilizer triphenyl phosphate 0.03%, oxidation stabilizer antioxidant 618, amount 0.04%, Then melt at a temperature of 265°C, inject tape, and pelletize to make spinning masterbatch. Configure high-shrinkage polyester according to the ratio of 40% of conventional polyester chips and dry. According to conventional polyester chips, 20-30% water-soluble polyester (COPET) is dried at a temperature of 100°C for 25 hours, and then 0.1% of dispersant liquid paraffin is added.

[0033] Pass the above-mentioned masterbatch, high-shrinkage polyester, and COPET through different screws, and melt them at temperatures of 270°C, 280°C, and 260°C respectively, adjust the injection volume of each screw according to the ratio, and pass the three molten materials together The special-shape...

Abstract

The invention relates to a superfine hetero composite elasticized fiber and its manufacturing method, special spinning equipment, spinning art and the related technique, uses routine polyester slice, highly contractive polyester, and so on as raw materials to prepare spinning solution, makes multicomponent composite spinning on the spinning solution and water soluble polyester, and then elasticizes to make a superfine isomeric composite elasticized fiber finished product, where single silks of the fiber are distributed like an island, and by post processing, the fineness of the fiber is up to 0.01-0.001 dan, and besides, the fiber has the superfine, different-contractive and different section properties. The fabric produced by this fiber has handwriting effect, especially soft handing, and humidity absorbing property up to and even over that of natural fiber, full, comfortable and good-air permeability; and the surface of the fabric has a shine like silk and good dyeing property. This fiber can be widely applied to the industries of machine weaving, knitting, silk manufacturing, etc., to manufacture minic, high grade clothing, blood filtering material, etc.

Description

technical field [0001] An ultrafine anisotropic composite elastic fiber and a manufacturing method thereof, the invention relates to the technical field of textiles. technical background [0002] At home and abroad, there have been ultra-fine fibers, fibers with different shrinkage and fibers with different cross-sections, and their respective manufacturing methods, but there is no one made by spinning at one time, and has ultra-fine fibers and different shrinkage at the same time. , Fibers with different cross-sectional properties, and a manufacturing method thereof. Contents of the invention [0003] The object of the present invention is to provide a kind of ultra-fine anisotropic composite stretching fiber and its manufacturing method. Specifically, it is a fiber made at one time by spinning, and has ultra-fine, different shrinkage, and different cross-section properties, and a manufacturing method of the fiber. Among them, the ultra-fine performance means that the f...
