Problems solved by technology

However, after the cotton yarn has been treated with saturated steam, there will be obvious yarn thick details in the yarn, which will affect the dry quality of the yarn
In addition, the operation of the yarn steaming machine is relatively complicated. If the steaming time and temperature are not well controlled, there will be water pollution on the surface of the yarn, which will cause the yarn to turn yellow and affect the appearance, internal quality and special properties of the yarn.
The yarn after steaming is relatively moist and must be dried in an oven, which increases energy consumption and cost
Furthermore, steaming equipment has no way to control its relative humidity, which often causes yarn damage
In the prior art, there is also a dry heat setting method for twist fixing, but the dry heat setting method has a poor twist fixing effect, and the fixing time can only be completed by increasing the qualitative time, which generally requires about 12 hours
This heat-set yarn fixing method is not only low in production efficiency, but also wastes a lot of energy and other aspects.

Embodiment 1

[0017] Cotton fibers with a fineness of 5475 public counts, an average fiber length of 29mm, and 85% by weight of vinylon and 15% by weight of vinylon are passed through the carding process of a digital sample carding machine, and then spun with a roving frame with a draft ratio of 6.6. Qualified rovings are machine-spun into 30Tex spun yarns through the spinning process, and the twist of the spun yarns is 180T / 10cm. Put the spun yarn into a water bath at a temperature of 50°C, heat it for 10 minutes, dissolve the vinylon, and fix the position of the cotton yarn after drying to obtain a pure cotton strong twist yarn.

[0018] The obtained pure cotton fixed-twisted yarn has uniform evenness, no rough details, no water pollution, and the overall effect is good.

Embodiment 2

[0020] Cotton fibers with a fineness of 5475 public counts, an average fiber length of 29mm, and 95% by weight of vinylon and 5% by weight of vinylon are passed through the carding process of a digital sample carding machine, and then spun out by a roving frame with a draft ratio of 8. Qualified rovings are machine-spun into 18Tex spun yarns through the spinning process, and the twist of the spun yarns is 250T / 10cm. Put the spun yarn into a water bath at a temperature of 30°C, heat it for 5 minutes, dissolve the vinylon, and fix the position of the cotton yarn after drying to obtain a pure cotton strong twisted yarn.

[0021] The obtained pure cotton fixed-twisted yarn has uniform evenness, no rough details, no water pollution, and the overall effect is good.

Embodiment 3

[0023] Cotton fibers with a fineness of 5475 metric counts, an average fiber length of 29mm, and 90% by weight of vinylon and 10% by weight of vinylon are passed through the carding process of a digital sample carding machine, and then spun out with a roving frame with a draft ratio of 7. Qualified rovings are machine-spun into 20Tex spun yarns through the spinning process, and the twist of the spun yarns is 220T / 10cm. Put the spun yarn into a water bath at a temperature of 40°C, heat it for 8 minutes, dissolve the vinylon, and fix the position of the cotton yarn after drying to obtain a pure cotton strong twisted yarn.

[0024] The obtained pure cotton fixed-twisted yarn has uniform evenness, no rough details, no water pollution, and the overall effect is good.

Abstract

The invention discloses a manufacturing method of pure-cotton strong twisted yarns. According to the method, 80 to 95 percentage by weight of cotton fibers and 5 to 20 percentage by weight of water soluble vinylon are blended through a blending technology, blended yarns with high twist are manufactured by spinning, then hot water with the temperature of 30 to 80 DEG C is used for treating the blended yarns for 5 to 40min, and the positions of the cotton fibers are fixed by using half-soluble vinylon as an adhesive, so as to realize the aim of fixing yarn twist and further prepare the pure-cotton strong twisted yarns. The method has the characteristics of being simple in process, high in efficiency, stable in product quality, convenient in industrialization application and the like. The obtained pure-cotton strong twisted yarns have the characteristics that the yarn twist is high and stable, the yarn production is facilitated, the pure-cotton strong twisted yarns are suitable for weaving strong twisted yarn fabric with special effect, and the like.

Description

technical field [0001] The invention relates to spinning technology, in particular to a method for manufacturing pure cotton strong twisted yarn. Background technique [0002] With the development of society and the further improvement of people's living standards, people have great demands for the beauty, comfort, environmental protection, and functions of clothing. The development of high-grade cotton fabric with strong twist yarn is a technology to meet this demand. The spinning of strong twist yarn and the fixed twist of yarn are relatively difficult. At present, most enterprises in the domestic cotton spinning industry use the method of workshop storage and natural rehydration to make the yarn achieve the effect of fixed twist or fixed twist, which is called the natural fixed twist method. The advantage of this method is that the process is simple and the yarn is less affected. However, the disadvantages of this method are also obvious. The yarns occupy a large area,...
