specific Embodiment approach

[0035] The specific embodiment of the present invention comprises the following steps:

[0036] 1. Selection of fiber raw materials:

[0037] Select fiber fineness 17~19 μm, length 28~32mm, consumption is 95~97% yak wool fiber; Silk fiber fiber fineness 11~16 μm, length 38mm consumption is 3~5% silk fiber as raw material.

[0038] 2. Blending: Use blending machine for blending. The best blending machine is BC266 blending machine. The parameters of the blending process are as follows: the feeding amount is 25-30kg / time; the established moisture regain is 14.5%; and Crude oil dosage: 0.8%; antistatic agent dosage: 0.6% antistatic agent.

[0039] 3. Spinning:

[0040] 31) Combing: use a carding machine for carding, and the carding machine is preferably A186F carding machine; the parameters of the carding process are as follows: regain moisture on the machine: 25.23%; sliver weight: 2.2~2.6g / m; speed: 50Hz ;

[0041] 32) Pre-drawing: Use a draw frame for pre-drawing, preferabl...

Embodiment 1

[0060] Example 1, develop a worsted yak cashmere cardigan with a ribbed air layer structure produced by worsted yak cashmere yarn with a fineness of 17.9×2tex. Its production process is as follows:

[0061] 1. Selection of fiber raw materials: 95% of yak cashmere fiber, 17 μm of fiber fineness, and 31 mm in length; 5% of silk fiber, 15 μm of fiber fineness, and 38 mm in length.

[0062] 2. Wool: Mix yak wool fiber with silk fiber, mix 0.8% FX903 type wool oil and 0.6% antistatic agent with water, add it to the fiber, and then mix the fiber evenly on the wool machine. Afterwards, it is packed and stuffed for 3 hours, and the process parameters are: kneading machine: BC266 kneading machine; feeding amount: 25kg / time; public moisture regain: 14.5%.

[0063] 3. Spinning:

[0064] 31) Carding: The parameters of the carding process are: carding machine: A186F carding machine; moisture regain on the machine: 25.23%; sliver weight: 2.2g / m; speed: 50Hz;

[0065] 32) Pre-drawing: The...

Embodiment 2

[0082] Example 2, develop the worsted yak wool sweater with rib semi-air layer structure produced by worsted yak wool yarn with a fineness of 20.8×2tex. Its production process is as follows:

[0083] 1. Selection of fiber raw materials: 96% of yak cashmere fiber, 18 μm of fiber fineness, and 30 mm in length; 4% of silk fiber, 13 μm of fiber fineness, and 38 mm in length.

[0084] 2. Wool: Mix yak wool fiber with silk fiber, mix 0.8% FX903 type wool oil and 0.6% antistatic agent with water, add it to the fiber, and then mix the fiber evenly on the wool machine. Afterwards, pack and stuff the wool for 3 hours, and the process parameters are: kneading machine: BC266 kneading machine; feeding amount: 27kg / time; public moisture regain: 14.5%.

[0085] 3. Spinning:

[0086] 31) Carding: the parameters of the carding process are: carding machine: A186F carding machine; moisture regain on the machine: 25.23%; sliver weight: 2.4g / m; speed: 50Hz;

[0087] 32) Pre-drawing: The paramet...

Abstract

The present invention relates to textile technology, and is especially production process of fine yak wool sweater. The production process includes following steps: selecting fiber material including yak wool fiber in 95-97 wt% and silk fiber in 3-5 wt%; mixing the yak wool fiber and the silk fiber inside one mixer; spinning; knitting yak wool sweater pieces in one flat knitting machine; sewing the pieces in sewing machine into yak wool sweater in the required style; and finishing. The present invention is superior to background technology.

Description

1. Technical field [0001] The invention relates to the field of textiles, in particular to a method for producing worsted yak cashmere sweaters. 2. Background technology [0002] Because yak cashmere fiber has the characteristics of softness, slipperiness, good elasticity, fluffy and warm, the yak cashmere knitwear made of it has rich appearance, soft hand feeling, good warmth retention, natural color and elegant tone, and is ideal for high-end clothing. Products, therefore, yak cashmere raw materials are increasingly valued by the textile industry, and the variety of yak cashmere products is also increasing. However, the development of past yak cashmere products was mainly woven with slub yarns spun on wool spinning equipment, and the developed slub yak cashmere products are thick and rough. With the development of knitted garments in the direction of lightness and high-grade in recent years, the traditional woolen yak sweater can no longer meet people's requirements due t...
