Compact-spun combed cotton yarn (300S) and spinning process thereof

Abstract

The invention relates to the technical field of spinning, in particular to a compact-spun combed cotton yarn (300S) and a spinning process thereof. The spinning process includes the steps of blowing,carding, preparing, combing, drawing, roving, spinning and spooling; the 300S cotton yarn refers to the compact-spun combed cotton yarn (300S) prepared by the spinning process. According to spinning process of the compact-spun combed cotton yarn (300S), combing and drawing are adopted so that a production flow is shortened, reduction of lower pile increase is facilitated, and uneven drafting is reduced; the cotton yarn prepared by the process has the advantages of high strength of single yarn, uniform sliver and less yarn defects. By the spinning process, yarn forming process and cloth style stability are both guaranteed, production cost of the spinning factory is reduced greatly, and performance of enterprises is increased.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a compact-spun combed 300-count cotton yarn and a spinning process thereof. Background technique [0002] Compact spinning, also known as compact spinning, compression spinning or condensed spinning, is a new type of spinning technology that is spun on an improved ring spinning frame. Its core technology is to install a compacting device at the output end of the front roller. , so that the strands are gathered and then output for twisting, which realizes the separation of drafting and accumulation, and avoids the influence of friction force distribution due to the existence of aggregation in the drafting area. The twist triangular area is reduced or even eliminated, thereby eliminating the adverse effects caused by the existence of the twisting triangular area and improving the yarn quality. [0003] The count is the unit that indicates the thickness of the yarn. For the same y...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the technical problems of long process, high cost and labor-intensive, the present invention provides a compact spinning worsted spinning technology for the production of 300 ultra-high-count cotton yarns in the existing compact spinning technology, which needs to adopt two combing and two drawing frames. Combing 300-count cotton yarn and its spinning process. The spinning process not only reduces production costs and labor costs, but also ensures the quality of the yarn. The 300-count cotton yarn produced is uniform, has fewer yarn defects, and has high strength.
