Technology for processing textile wastes into regenerated cotton

Abstract

The invention discloses a technology for processing textile wastes into regenerated cotton, and belongs to the technical field of regenerated cotton yarn processing. The technology comprises the steps of manual sorting, opening cotton, carding cotton, drawing and spinning, wherein in the steps of opening cotton and carding cotton, the proportion of humidifying different raw materials is 6% to 8% of the weight of the raw materials, relative humidity is ensured to be 63% to 67%, equipment is used for separating fiber bundles and removing impurities through the acting force of hitting, pulling and rolling, and fiber damage is reduced as far as possible; constant temperature environment of 20 DEG C+ / -2 DEG C is controlled in a cotton opening and carding workshop. According to the technical scheme which adopts reasonable humidity control a three-row roller compressing structure, and frequency conversion control under the constant temperature environment, the raw materials are always fed at a constant speed under a stable large-tension state, the effects of completing opening and carding the cotton at one time, remaining no excess materials and avoiding secondary opening cotton are achieved, at the same time, the constant temperature environment enables the technology to be more stable, and the product quality is improved.

Description

technical field [0001] The invention belongs to the field of solid waste treatment and comprehensive utilization, and relates to a process for processing textile waste regenerated cotton. Background technique [0002] In the production of the current textile manufacturing industry, a large amount of industrial textile waste, such as the leftover materials and waste silk produced in the process of spinning, weaving, and garment processing, are all treated as landfills or incinerated by thermal power generation. It is a waste of resources and seriously pollutes the environment. [0003] The traditional recycled cotton processing technology such as figure 1 As shown, it includes manual sorting, cotton opening, carding, residual material opening, carding, slitting, and spinning steps, and finally forms cotton yarn. [0004] The traditional cotton opening and carding process is mostly carried out with gears, and manual replacement of gears is often used. The process is complica...

AI Technical Summary

Problems solved by technology

[0004] The traditional cotton opening and carding process is mostly carried out with gears, and manual replacement of gears is often used. The process is complicated, and vibrations will occur due to the gaps in the gear ratio process during mechanical operation, resulting in poor fiber quality. Stable, there is a large amount of residual material, and the second opening must be carried out; in the opening process, temperature and humidity have a great influence on the quality of the opening fiber. In the traditional opening process, the temperature difference leads to the length and The strength and quality are difficult to stabilize; and in the structure of the opener, two rows of rollers are used to compress the structure, often due to insufficient tension, which affects production efficiency
