Problems solved by technology

The disadvantages are: viscose fiber feels heavy, has poor elasticity and is easy to wrinkle, and is not crisp
The above-mentioned products feel soft and not smooth enough. At the same time, the elasticity is average, the wear resistance is poor, and they tend to shrink after washing.

Embodiment 1

[0049] The process steps of this embodiment include raw material selection, wool filling, wool blending, carding, drawing, roving, spun yarn, self-winding, doubling, two-for-one twisting, and finished product packaging. The steps are as follows:

[0050] Raw material selection: The raw material is composed of cotton fiber, nylon fiber and viscose fiber; the cotton fiber is first bleached, and the prescription is as follows:

[0051] Hydrogen peroxide / (g / L) 10-30

[0052] EDTA / (g / L) 5

[0053] pH 8-10

[0054] Bath ratio 20:1

[0055] Temperature / ℃ 60-80

[0056] Time / min 60-120

[0057] Finally, after washing and drying;

[0058] Afterwards, the raw material treatment includes the stuffing and wooling process;

[0059] The stuffing process is:

[0060] Spray the nylon fiber with antistatic agent and treatment liquid containing crude oil, and then disperse and mix it. The mass ratio of oil is controlled at 0.5%-1%, antistatic agent is controlled at 0.7%-1.3%, and the wool ...

Embodiment 2

[0072] Other processing steps in the above-mentioned embodiment are constant, and the bleaching treatment step of cotton fiber has change, and preferred prescription is as follows:

[0073] Hydrogen peroxide / (g / L) 20

[0074] EDTA / (g / L) 5

[0075] pH 10

[0076] Bath ratio 20:1

[0077] Temperature / ℃ 60

[0078] time / min 90

[0079] Finally, after washing and drying.

[0080] Experiments have shown that: with the increase of hydrogen peroxide mass concentration, the whiteness and strength of cotton fiber first increase and then decrease, while the alkali solubility of wool shows an upward trend. As the amount of hydrogen peroxide increases, the bleaching ability of the bleaching solution increases; when the pigment in the fiber is basically destroyed by the reaction, the whiteness will no longer increase with the increase in the amount of hydrogen peroxide, while hydrogen peroxide decolorizes the pigment. Fibers can also be damaged. Therefore, it is advisable to take th...

Embodiment 3

[0082] A semi-worsted blended colored yarn, which is made by the above-mentioned spinning process, and the obtained yarn consists of 53 parts by weight of cotton fiber, 7 parts of nylon fiber, and 40 parts of viscose fiber, and the specification is 2 / 32Nm.

Abstract

The invention relates to a yarn spinning technology for semi-worsted and blended colored yarn and the yarn prepared with the technology. The technological steps mainly comprise raw material treatment, cotton carding, drawing, roving, spinning, self-spooling, doubling, two-for-one twisting and packaging of a finished product. Raw materials comprise cotton fiber, nylon fiber and viscose fiber. The cotton fiber is treated with a more efficient bleaching method, meanwhile, nylon and viscose ingredients are added, and the heat retention property, the elasticity, the durability and the comfort degree of the product are improved; the production cost is lower, the prepared yarn has the characteristics of shrink resistance, good anti-pilling effect, natural luster, bright color, good elasticity, smooth hand feeling, heat retention and the like.

Description

technical field [0001] The invention relates to a spinning process of yarn and the yarn, in particular to a spinning process of semi-worsted blended colored yarn and the yarn prepared by the process. Background technique [0002] With the advancement of technology, semi-worsted spinning has gradually evolved into a spinning system between cotton spinning and wool worsted spinning. The raw material is close to cotton spinning, the equipment is mixed with cotton and wool, and the product style is similar to worsted spinning. Semi-worsted spinning integrates the essence of wool spinning and cotton spinning, and the number of production passes is less than half of that of worsted spinning. Due to the many technical advantages of cotton spinning equipment, the adaptability of raw materials is wider, combined with wool spinning dyeing and raw material processing related technologies, the fineness of spinning has greatly exceeded the original restricted area of ​​wool spinning, and...
