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

[0036] 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:

[0037] Selection of raw materials: raw materials are composed of mercerized wool fiber, nylon fiber, viscose fiber and cashmere fiber; mercerized wool fiber is obtained by processing wool as follows:

[0038] (1) Washing wool: wash the wool in the washing liquid at a constant temperature of 30°C, and dry it at 80°C after washing;

[0039] (2) Hydrogen peroxide treatment of wool: Put the wool into a mixed solution containing 30% hydrogen peroxide 35ml / L, sodium pyrophosphate 1.0g / L, and a pH value of 7.5, and treat it for 35 minutes at a temperature of 45°C and a bath ratio of 1:30;

[0040] (3) Protease treatment of wool spinning; the amount of protease added is 2%, the treatment temperature is 50°C, and the treatment time is 60 minu...

Embodiment 2

[0054] A multi-fiber mixed-color semi-worsted yarn, which is made by the above-mentioned spinning process, and the obtained yarn is composed of 40 parts by weight of mercerized wool fiber, 30 parts of nylon fiber, 25 parts of viscose fiber, cashmere 5 parts of fiber, the specification is 2 / 28Nm.

Abstract

The invention relates to a yarn spinning technology for multi-fiber semi-worsted melange yarn and the yarn prepared with the technology. The technological steps of the yarn 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 mercerized wool fiber, nylon fiber, viscose fiber and cashmere wool fiber. The problems of high probability of water shrinkage and pilling of wool are solved with a more environment-friendly method, meanwhile, nylon, cashmere wool and viscose ingredients are added, and the heat retention property, the elasticity, the durability and the comfort degree of the product are increased; 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 a yarn and the yarn, in particular to a spinning process of a multi-fiber mixed-color semi-worsted 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 s...
