Problems solved by technology

[0002] At present, the yarn used in textiles has a large twist, which makes the fibers tightly pressed together, which cannot ensure a softer and fuller cloth surface. If the yarn twist is reduced, the cloth surface can be improved, but if the twist is too small, the yarn will The strength is reduced, which brings great difficulties to textile weaving
In addition, through a patent search, an invention patent in my country was found, the application (patent) number: 99120475.1, a long-staple cotton untwisted yarn and its spinning method, which is spun from long-staple cotton and soluble yarn. However, the cost of the invention patent technology is relatively high

Embodiment 1

[0017] Embodiment 1: While spinning single yarn (1), spin water-soluble vinylon yarn (2) of 60-100 English counts, twist and spin 30-50 British counts of untwisted yarns on the twisting machine after doubling Yarn. Its process flow: single yarn - cleaning - carding - drawing (2 roads) - roving - spun yarn - winding; water-soluble vinylon - cleaning - carding - drawing (2 roads) - roving - spun yarn - Winding; then two single yarns are paralleled-twisted-winded into yarn.

Embodiment 2

[0018] Example 2: After spinning untwisted pure cotton single yarn (1), use 97-58dexV water-soluble vinylon filament (2) as a finished product, and then twist and spin a qualified product on a twisting machine through doubling. The process Process: single yarn - cleaning - carding - drawing (2 passes) - roving - spun yarn - winding; use 97 ~ 58dtex water-soluble vinylon filament (2), and then two single yarns are paralleled - twisted - winding Tube into yarn.

Abstract

The invention relates to an un-twist knitwear and the manufacturing process, belonging to the spinning area, characterized in that the central part of yarn is single-yarn and the outer is covered by water-soluble vinylon yarn or water-soluble vinylon filament. Single yarn and water-soluble vinylon yarn or water-soluble vinylon filament are respectively weaved. The process of single yarn and water-soluble vinylon yarn is blowing, carding, drawing frame, roving, spinning and winding, and then un-twist knitwear is formed from single yarn and water-soluble vinylon yarn or filament by drawing frame, twisting and winding. Strength needed by waving is achieved entirely and the cost is lower than the cost of long-staple cotton un-twist yarn by 1/3. At the same time, handling, fullness, water-absorption and permeability of fabrics achieve the optimal status. The fabric is very comfortable.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to a non-twisted yarn fabric and a preparation method thereof. Background technique [0002] At present, the yarn used in textiles has a large twist, which makes the fibers tightly pressed together, which cannot ensure a softer and fuller cloth surface. If the yarn twist is reduced, the cloth surface can be improved, but if the twist is too small, the yarn will The strength is reduced, which brings great difficulties to textile weaving. In addition, through a patent search, an invention patent in my country was found, the application (patent) number: 99120475.1, a long-staple cotton untwisted yarn and its spinning method, which is made of long-staple cotton and soluble yarn. However, the cost of this invention patent technology is relatively high. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned existing problems and provide a non-...
