Ring spindle spinning process

Abstract

The ring spindle spinning process includes one roving step and one spinning step, the roving step has roving line density of 600-1200 Tex, and the spinning step has spun yarn in the ratio between drafting multiple and English count of 1.03-2.06 time / English count. Before the roving step, there are drawing step, combing step and carding step to result in semi-finished goods top with linear density of 5.0-7.5 G / m and silver lap line density of 75-120 G / m. The spinning process includes also scutching step with lap ration of 600-1000 G / m. The technological process of the present invention has improved spun yarn quality, less configured fore-spinning apparatus and lowered comprehensive spinning cost.

Description

technical field [0001] The invention relates to the process setting in the ring spinning process in the textile industry, in particular to the setting method of the quantification of each process of the pre-spinning process and the drafting multiple of the spinning process. Background technique [0002] The ring spinning process is a process of spinning raw cotton or chemical fiber into a finished spun yarn with a certain count or special number (Tex). Generally speaking, the current spinning process is nothing more than two forms. One process is the carded spinning process including opening and cleaning, carding, drawing, roving, spun yarn and other processes; the other process is in the The combed spinning process in which the combing process is added between the carding and drawing processes of the carded spinning process. Each process of spinning has the effect of continuously elongating and thinning the semi-finished product, which is commonly referred to as drafting. ...

Problems solved by technology

[0008] In short, in the existing spinning process methods, due to the principle of light weight process, it is difficult for the industry to get rid of the thinking mode of "one count per pound". This process principle and practical practice have seriously restricted the drafting ratio of spun yarn and Even the quantitative improvement of each process in the whole pre-spinning process makes it difficult to exert the production efficiency of the spinning equipment and the utilization rate of the equipment is not high, which objectively increases the equipment configuration of the spinning process, that is, under the same production capacity, it needs Configure more spinning equipment

On the one hand, this will inevitably bring about an increase in equipment costs and plant investment, and on the other hand, it will also bring about an increase in operating costs such as electricity, labor, operating costs, and equipment maintenance.
