Spinning yarn overview
1. The Concept of Spinning Yarn
The spinning process is the last process in spinning production. It is to spin the roving into a spun yarn with certain characteristics, in line with quality standards or customer requirements, for use in twisting, woven or knitted fabrics, etc. .
2. Tasks of spun yarn
1. Drafting: Evenly stretch and thin the fed roving or sliver to the special number required by the spun yarn.
2. Twisting: Add appropriate twist to the drafted sliver, so that the yarn has certain physical and mechanical properties such as strength, elasticity, finish and feel.
3. Winding and forming: The spun yarn is wound on the bobbin according to certain forming requirements to facilitate transportation, storage and subsequent processing.
3. The position of the spinning process in spinning
1. The number of spinning machines determines the scale of the enterprise.
2. The output of the spinning machine determines the production level of the enterprise.
3. The quality of spun yarn determines the quality of finished yarn.
4. The amount consumed in the spinning process determines the cost of spinning.
5. The end-break rate per thousand spindles of spinning yarn is an important indicator for enterprise assessment.
In short, spinning is a particularly important process in spinning. The production scale of a cotton textile factory is often expressed by the total number of spindles of the spinning machine. The spinning output is the basis for deciding the number of machines to be equipped in each process of the spinning factory; the production quality level The consumption of raw materials, machine materials, electricity, etc., labor productivity, equipment integrity rate, etc. also reflect the quality of the spinning mill’s production technology and management level.
