Problems solved by technology

However, cashmere knitted products have always had a prominent problem: the wet elasticity of the fabric is poor, and the resilience performance is poor (the elongation at break of cashmere yarn is generally only 10% to 15%), which makes the dimensional stabil

Embodiment 1

[0023] 1. Material selection: 15.0um medium fineness carded cashmere is preferred as raw material.

[0024] 2. Cashmere washing: three gentle openings are used before washing, the raw cashmere is decomposed in large pieces during the first opening, part of the grass clippings and sediment in the raw cashmere are removed during the second opening, and the focus is removed during the third opening Part of the skin; the three gentle openings make the raw cashmere fully loosen and the fiber damage is small, and the partial removal of impurities reduces the pressure of washing and carding in the subsequent process. Use neutral detergent and low temperature washing wool, lower temperature drying

[0025] 3. Carding: Set two sets of working rollers and plucking rollers on the carding machine. In the traditional carding process, add a dust removal device for falling objects, and add two carding machines to adjust the angle of the carding roller card clothing to 130°.

Abstract

The invention belongs to the technical field of knitting yarns and production technology thereof, in particular relates to a cashmere yarn with high tensile stretch and production technology thereof. The production technology of the cashmere yarn with high tensile stretch includes the followings: in cashmere washing step, drying is carried out at the low temperature of 40 DEG C to 50 DEG C so as to reduce the power damage of cashmere single fiber; in carding step, the card clothing angle of cubing rolls of a carding machine is adjusted between 130 DEG and 150 DEG so that the striking point direction of cubing rolls is changed and the length damage of cashmere is reduced; in dying step, drying is carried out at the low temperature of 50 DEG C to 70 DEG C so as to further reduce the power damage of cashmere single fiber; in spinning step, the twist factor of the single yarn used is 90% to 98%. In the invention, drying is carried out at the low temperature of 40 DEG C to 50 DEG C both in cashmere washing step and in dying step, and the card clothing angle of cubing rolls of a carding machine is adjusted between 130 DEG and 150 DEG in carding step, thereby reducing the damage of cashmere to the maximum and guaranteeing high breaking elongation, rebound degree and force of cashmere.

Description

technical field [0001] The invention belongs to the technical field of knitting yarn and its production process, and in particular relates to a high-elongation cashmere yarn and its production process. Background technique [0002] With the development of science and technology and productivity, people's material living standards continue to improve, and the requirements for clothing are getting higher and higher. Health care, comfort, beauty, and easy washing have become the pursuit of clothing products. Because of its high elasticity and comfortable wearing characteristics, knitted fabrics meet people's needs for comfortable and leisure clothing. Therefore, the demand for knitted clothing in the domestic market is increasing year by year. [0003] According to the statistics of China Knitting Industry Association, in the past five years, the average annual growth rate of sales of enterprises in the knitting industry has reached 15%. Among them, as medium and high-end knit...
