Problems solved by technology

The surface of water-soluble fiber is smooth, but its antistatic ability is weak, and because the thickness and density of cashmere and water-soluble fiber are different, it is difficult to mix.
[0005] On the other hand, when water-soluble fiber is blended with cashmere, since the proportion of PVA is not large and the fiber is relatively thin, it is also difficult to mix evenly. Increasing the proportion of water-soluble fiber is conducive to uniform mixing, but the proportion of water-soluble fiber is too high High, the yarn count will be greatly increased after washing, but the fabric structure will be loose after finishing, and the wearability of the product will be reduced
Therefore, when blending water-soluble fiber and cashmere, it is usually necessary to increase the number of mixing channels from 3 to 5, and the effect is not stable

Embodiment 1

[0026] A water-soluble fiber and high-count cashmere yarn spinning process, the steps are as follows:

[0027] (1) Mix the water-soluble fiber and cashmere evenly with a wool blending machine, and feed a total of 64 kg, including 48 kg of cashmere, accounting for 75%, 16 kg of water-soluble fiber, accounting for 25%, and the average length of cashmere is 32~36mm. The fineness is 15.5-16.0μm, and the short cashmere rate is less than 15%. The water-soluble fiber is polyvinyl alcohol fiber, the length is 38mm, and the fineness is 1.5D. Add 3.5% crude oil FX-906 and 1.5% antistatic agent FX-AS301 into normal temperature (20°C) deionized water or distilled water under stirring, and stir for 10-15 minutes to form a uniform solution. Add the oil and water to the cashmere by spraying. The oil and water are only added to the cashmere after opening. The moisture regain of the cashmere on the machine is controlled at 24~26%. After the sexual fibers are interlaced and tiled in 4 layers, ...

Abstract

The invention relates to a water-soluble fiber and high-count cashmere yarn spinning process. The process comprises the following specific steps of (1) firstly opening cashmere, adding oil and water,then preliminarily mixing the cashmere and water-soluble fibers, and feeding a mixture into a mixing willow for full mixing; (2) processing the mixture obtained in the step (1) into rough yarns by using a carding machine, and controlling the temperature of a carding workshop to be 24-26 DEG C and the humidity to be 60-65%; (3) drafting and twisting the rough yarns obtained in the step (2) by a spinning frame to form spun yarns, winding the spun yarns into yarn ears, controlling the temperature of the carding workshop to be 20-30 DEG C and the humidity to be 60-65%, and controlling the draft multiple of the spun yarns to be 1.30-1.35; and (4) performing bobbin replacement and winding on the spun yarns by using a bobbin winder, and removing relatively thin or thick slivers at the same time.According to the process, on one hand, the spinning process is improved, and on the other hand, the water-soluble fibers are modified, so that the cashmere and the water-soluble fibers can be uniformly mixed in the wool mixing stage, after the water-soluble fibers are removed through water washing, the slivers can be uniform, and the wearability of a product is good.

Description

technical field [0001] The invention relates to the technical field of cashmere textiles, in particular to a water-soluble fiber and high-count cashmere yarn spinning process. Background technique [0002] In recent years, the development of textile fabrics presents a trend of "diversified raw materials, light and thin structure, trendy style, and functional use". The development of high-count ultra-thin fabrics by spinning cashmere / wool with water-soluble fibers has also become a new application field for water-soluble PVA fibers. After blending water-soluble fiber and cashmere, a high-count ultra-thin fabric is obtained, which not only has more outstanding elasticity, drapability, and bulkiness, but also improves spinning and weaving efficiency, making the fabric more high-grade, and expanding the cashmere. The scope of use greatly reduces the unit cost of the product, making it have broader development prospects and good economic benefits. [0003] At present, the water...
