preparation example Construction

[0033] The invention provides a kind of preparation method of yak cashmere yarn, comprises the following steps:

[0034] Mix yak hair, health-preserving additives and water and then veneer to obtain health-preserving yak hair;

[0035] After mixing the health-preserving yak cashmere and water-soluble fiber, carding is carried out to obtain a raw sliver of the mixture;

[0036] Drawing the mixture raw sliver to obtain fiber cooked sliver;

[0037] Carrying out roving to the fiber cooked slivers to obtain roving;

[0038] Fine spinning the roving to obtain a single-ply yarn;

[0039] Paralleling the single yarns to obtain multiple yarns;

[0040] The multi-ply yarn is twisted to obtain yak cashmere yarn.

[0041] The preparation method of the yak cashmere yarn provided by the present invention is preferably carried out in the air, and the air ambient temperature is preferably 23-28°C, more preferably 24-27°C, most preferably 25-26°C; the air ambient humidity is preferably 55...

Embodiment 1

[0066] Raw material preparation: take 80% (weight ratio) of yak wool fiber and 20% (weight ratio) of water-soluble fiber.

[0067] Health care: mix according to the ratio to get health care aids: 1 part of crude oil, 0.4 parts of antistatic agent, 20 parts of water; the mixed health care aids are sprayed on the yak wool fiber according to the mass ratio of 1:100 and Stew the wool for 24 hours, and turn over the warehouse twice after 24 hours; the moisture regain is controlled at 22% to 25%.

[0068] Opening and mixing: the water-soluble fiber is sent to the opening machine for pre-opening, and the water-soluble fiber after pre-opening is mixed with the yak wool fiber processed in the previous step. The water-soluble fiber and yak wool fiber are sent to the wool feeding machine for further mixing, and the unevenness is controlled below 1.2%.

[0069] Carding: The cylinder speed of the carding machine is controlled at 260 rpm; the five-point distance between the cover plate and...

Embodiment 2

[0078] Raw material preparation: take 85% (weight ratio) of yak wool fiber and 15% (weight ratio) of water-soluble fiber.

[0079] Health care: mix according to the ratio to get the health care aids: 1 part of crude oil, 0.45 parts of antistatic agent, 21 parts of water; the mixed health care aids are sprayed on the yak wool fibers according to the mass ratio of 1:100 and Stew the wool for 24 hours, and turn over the warehouse twice after 24 hours; the moisture regain is controlled at 22% to 25%.

[0080] Opening and mixing: the water-soluble fiber is sent to the opening machine for pre-opening, and the water-soluble fiber after pre-opening is mixed with the yak wool fiber processed in the previous step. The water-soluble fiber and yak wool fiber are sent to the wool feeding machine for further mixing, and the unevenness is controlled below 1.2%.

Abstract

The invention provides a preparation method of yakwool yarns. The preparation method comprises the following steps: mixing yakwool with a health maintaining auxiliary and then covering tightly to obtain health maintaining yakwool; mixing the health maintaining yakwool with water-soluble fiber and then carding to obtain a mixture card sliver; drawing the mixture card silver to obtain fiber drawn sliver; roving the fiber drawn sliver to obtain rough yarn; performing fine spinning of the rough yarn to obtain one-ply yarn; doubling multiple one-ply yarns to obtain plied yarns; twisting the plied yarns to obtain a finished product of yarn; and washing the finished product of yarn to obtain yakwool yarns. In the preparation method provided by the invention, the doping fiber added in a spinning process can be removed to obtain pure yakwool fiber. Moreover, by adding and removing water-soluble fiber in the middle process, the count of the yakwool fiber can be increased.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a yak cashmere yarn and a preparation method thereof. Background technique [0002] Yak cashmere is the hair of yaks that grow on the alpine grasslands of China's Qinghai-Tibet Plateau and its adjacent areas. It is light in weight, short in length and delicate in hand. Yaks are harvested once a year. The annual hair output of adult yaks is 1.17-2.62kg / yak, and that of young cattle is 1.30-1.35kg / yak, of which coarse hair and fine hair account for half. Yak velvet is very thin, with a diameter of less than 20 microns and a length of about 2.6 to 2.8 cm. It is irregularly curved, and the scales are ring-shaped and closely entangled. The luster is soft, the elasticity is strong, and the hand feels smooth and waxy. [0003] As a textile fabric, yak cashmere is warmer and softer than ordinary wool, and has been used in the field of clothing production in recent years. The existing ...
