Embodiment 1

[0037] The high-efficiency processing method of the high-count yak cashmere yarn for the worsted product of the present embodiment includes:

[0038] The first step is to pretreat the yak cashmere fiber raw material, which includes: picking and removing foreign fibers.

[0039] Due to the large difference in length and thickness of yak down fiber, it is first necessary to sort the raw materials and pick out the foreign fibers.

[0040] In the second step, the yak wool fiber obtained in the first step is sprayed with hair oil, antistatic agent, yarn reinforcing agent and water layer by layer, while controlling the moisture regain within a preset range and balancing the preset time. To increase the lubrication between fibers, reduce static electricity, reduce the directional friction effect of fibers, and increase the cohesion between fibers.

[0041] Specifically: based on the weight of the yak cashmere fiber obtained in the first step, add 0.6% FX-906 type and crude oil, 0.45...

Embodiment 2

[0062] The high-efficiency processing method of high-count yak cashmere yarn for worsted products of the present embodiment, the basic steps are the same as in Example 1, and the specific parameters of each step are different, as follows:

[0063] (1) In the second step, based on the weight of the yak wool fiber obtained in the first step, add 0.8% FX-906 type and crude oil, 0.50% FX-AS20 antistatic agent, 0.48% FX - VSI type yarn strengthening agent and 10% water, control moisture regain at 24%, balance for 24h.

[0064] (2) In the third step:

[0065] In the carding process, the process parameters are: feeding roller speed 4.2r / min, cylinder speed 270r / min, doffer speed 20r / min, sliver weight 9.0g / m.

[0066] In the first pre-drawing process, the process parameters are: the number of pre-drawings is 6, the draft ratio in the rear area is 1.12; the center distance of the front rollers is 45mm, the center distance of the middle rollers is 45mm, and the rear rollers The cente...

Abstract

The invention relates to an efficient processing method for fine yakwool yarn for worsted products. The method includes pretreating yakwool fibrous materials; adding wool oil; subjecting yakwool fibers to carding process, first pre-drawing process, first sliver lapping process, first combing process, second pre-drawing process, second sliver lapping process and second combing process; performing gilling process and spinning process to obtain the yakwool yarn with fineness of 80-120Nm. The processing method combining cotton-type carding and wool spinning gilling is adopted according to features of the yakwool fibers, the fine yakwool yarn with fineness of 80-120Nm can be finally obtained, utilization rate of yakwool is increased greatly, and added value of yakwool worsted products is enhanced; meanwhile, the technical means combining superhigh draft and all-compact spinning is applied to the spinning process, so that draft multiple can be increased effectively, the roving process is omitted, processing cost is reduced, production efficiency is improved, and efficient processing is realized.

Description

technical field [0001] The invention relates to a high-efficiency processing method for high-count yak cashmere yarn for worsted products. Background technique [0002] According to the applicant's knowledge, yak velvet can be obtained from yaks living above 3500m above sea level. The unique alpine climate determines that yak velvet has smooth texture, good elasticity, good moisture absorption and release performance, wear resistance and pilling resistance, and fiber strength. High quality, the average fineness of high-quality yak cashmere is 19μm, it is an ideal high-grade clothing fabric. At the same time, compared with cashmere, yak cashmere has better abrasion resistance and pilling resistance, and has an obvious price advantage. However, the fiber length of yak cashmere is shorter and the difference is large, which leads to the fact that yak cashmere is mostly used in the woolen process, and the product has additional lower value. [0003] After searching, it is found...
