Production method of tight sirospun yarn of combed crystal cotton

Abstract

The invention relates to a production method of tight sirospun yarn of combed crystal cotton. The production method comprises the following sequential working procedures: combed cotton preparation; opening, cleaning and blending of combed cotton and crystal cotton; cotton combing; drawing; roving; mixing of sirospun yarn of nylon filament; and winding. According to the invention, crystal cotton fiber is blended with the combed cotton fiber, the tight sirospun yarn of the nylon filament is added during the spinning working procedure, and a double-rough-yarn feeding device and a tight spinning device are additionally installed on a traditional ring spinning frame, so that two threads of rough yarn are simultaneously fed to a drafting region, a certain spacing is reserved between drafted fiber strands, and the drafted fiber strands are gathered, converged and twisted at the downstream of the roller chop to obtain yarn. Under the action that the fiber strand twisting triangular region is canceled due to bundling action and two threads of fiber strands are combined, the filoplume value of single yarn is obviously reduced, the yarn evenness is significantly improved, the fracture strength is greatly increased and better resultant yarn quality is obtained; and functional yarn with high strength, high hygroscopicity, cleanness, high elasticity and bacteriostatic characteristic is produced by the equipment.

Description

technical field [0001] The invention relates to a yarn production process, in particular to a production method that mixes new-type green fibers with high hollowness and traditional cotton fibers, uses nylon filaments as the skeleton, and spins yarns with special processing equipment. [0002] Background technique [0003] Crystal cotton fiber is a natural plant fruit fiber. Its length is similar to that of fine-staple cotton, its specific gravity is similar to that of cashmere, and its fiber hollowness is 70%-80% (cotton fiber hollowness is 10%-20%). . It has "the softness of cashmere, the luster of silk, and the toughness of cotton". Moreover, this kind of shrub grows in the subtropical zone and is very easy to cultivate. It can grow even in saline-alkali land, barren mountains, mudslides and river beaches. It does not need fertilization and medicine, and its vitality can reach more than 20 to 30 years. Cotton has great development potential. [0004] At present, the s...

Problems solved by technology

Crystal cotton fiber has excellent moisture absorption and dehydration performance, and has antibacterial properties, which can effectively make up for the shortcomings of cotton fiber. Although there are textiles containing crystal cotton fiber on the market, the proportion of use is very low (less than 20%). The scope is narrow (only limited to woven fabrics), and its role cannot be fully exerted, which affects its large-scale promotion

The increase in the proportion of crystal cotton fiber is due to its light specific gravity, high hollowness, and high rigidity, resulting in brittle fiber production, difficulty in pure spinning, increased yarn hairiness, low breaking strength, and significantly reduced performance.
