Problems solved by technology

[0003] At present, nylon long fibers are mainly used in the market, and nylon staple fibers are also available, but very few. More than 80% of nylon staple fibers are used in industrial yarns such as non-woven fabrics, and are rarely used in clothing.
The main reason why it is difficult to expand in the field of clothing is that the requirements for yarns used in clothing are relatively high, and it is difficult for domestic nylon fibers to meet this point, which is mainly reflected in the use of yarns made of domestic nylon fibers, which have many fine details. , many neps, poor evenness, many yarn defects, etc. If such yarns are used on clothing fabrics, problems such as poor cloth quality and poor dyeing uniformity will occur, so for clothing applications Use, the use of nylon fiber is only on the filament, the use of short fiber is very small
[0004] Disclosed in the Chinese patent CN101864632A is the yarn blended with nylon and wool, by adopting 80% wool and 20% nylon staple fiber to carry out blending to improve the problems such as wool yarn defects, the evenness of the obtained yarn, neps, Coarse details have been improved to a certain extent, but there are still relatively many; in addition, because 80% of the yarn is wool, the cost is high and the number of users is limited

Embodiment 1

[0033] Using the compact spinning process, the nylon 6 (NY6) raw cotton with an elongation at break of 40%, an oil content of 0.4%, a number of crimps of 14, and 1.5D*38mm is prepared as raw cotton (antistatic treatment)→cleaning and winding →Carding→drawing→roving→spinning→winding process for spinning to obtain 40s NY100% spun yarn.

[0034] The specific conditions of the above projects are as follows:

[0035] Raw cotton preparation: first prepare the antistatic agent and water according to the ratio of 2:100, then spray it evenly around the cotton bale according to the amount of 0.5L / 100kg, wrap it in a plastic bag after spraying, and place it for 24 hours;

[0036] Cleaning and rolling: the weight is controlled between 340 and 350g / m;

[0037] Carding: raw sliver basis weight 18g / 5m, flat to cylinder gauge 9 / 8 / 8 / 8 / 9, doffer speed 16rpm, licker-in roller 780rpm, cylinder 330rpm, sliver delivery speed 70m / min;

[0038] Draw frame: twice draw frame; 1 parallel 20g / 5m, 2 par...

Embodiment 2

[0043] Adopt compact spinning process, the NY6 raw slivers obtained after carding in Example 1 and the combed slivers formed by Xinjiang 229 combed cotton are drawn 3 times, and 1 mixed sliver 20g / 5m, 2 mixed sliver 18g / 5m during drawing , 3 and 18g / 5m, then carry out roving, spun yarn, winding project with embodiment 1, obtain the NY short fiber yarn of 40s, in the gained short fiber yarn, NY short fiber content is 50%, cotton content is 50%.

[0044] Among them, Xinjiang 129 carding raw sliver weight is 16g / 5m, cover plate to cylinder gauge is 8 / 7 / 7 / 7 / 8, doffer speed is 16rpm, licker-in roller is 880rpm, cylinder is 330rpm, and sliver delivery speed is 70m / min; When combing, the combed sliver weight is 16g / 5m, and the combed noil rate is 21%.

Embodiment 3

[0046]Using the compact spinning process, the NY6 raw cotton with an elongation at break of 50%, an oil content of 0.4%, a number of crimps of 12, and 1.2D*38mm was subjected to antistatic treatment according to the method of Example 1, and then mixed with 1.2 D*38mm viscose staple fibers are torn and mixed (artificially blended cotton). Take 300kg as a part. In each part, nylon accounts for 180kg and viscose accounts for 120kg. Prepare 4 parts, totaling 1200kg, and put them into the disc to grab cotton In the machine, it is used for the back road, and then carry out the cleaning and rolling, carding, drawing, roving, spun yarn, and winding engineering of the same embodiment 1 to obtain the NY staple yarn of 60s, and the NY staple fiber in the gained staple yarn The content is 60%, and the cotton content is 40%. Among them, the sliver weight in the roving project is 3.4g / 10m, and the twist coefficient is 0.7.

[0047] Artificial blending can fully mix two kinds of raw cotton ...

Abstract

The invention discloses a nylon-containing staple yarn, and a production method and application thereof. The staple yarn consists of 20 to 100 weight percent of nylon staple fibers and 80 to 0 weight percent of other staple fibers; the count of the staple yarn is 20-60s, and the yarn evenness is within 16 percent; the nep number is within 50 per kilometer. The production method is simple; the obtained nylon-containing staple yarn is even and has a few neps and a few slubs, the formed textile is smooth in cloth cover, high in quality and high in wear resistance and the application range of the nylon-containing staple yarn is expanded.

Description

technical field [0001] The invention relates to a spun yarn and a production method thereof, in particular to a nylon-containing spun yarn and a production method and application thereof. Background technique [0002] With the improvement of people's living standards, people's concept of fiber has not only stayed on cotton fiber, but more and more fibers have entered people's lives, especially nylon fiber. It is widely used in all kinds of clothing, and is frequently used as a raw material for high-end fabrics. [0003] At present, nylon long fibers are mainly used in the market, and nylon staple fibers are also available, but very few. More than 80% of nylon staple fibers are used in industrial yarns such as non-woven fabrics, and are rarely used in clothing. The main reason why it is difficult to expand in the field of clothing is that the requirements for yarns used in clothing are relatively high, and it is difficult for domestic nylon fibers to meet this point, which i...
