Ring spindle spinning process

Abstract

The ring spindle spinning process features that the great rationing spinning in all or partial fore-spinning steps of scotching, carding, pre-drawing, sliver lapping, combing, drawing and roving, and compared with traditional spinning process, the present invention has 40-100 % rationing increment of semi-finished goods. The present invention has greatly raised production capacity of the fore-spinning apparatus, and can results in obvious economic effect.

Description

Technical field [0001] The invention relates to the process setting and application of the ring spinning process in the textile industry, especially the quantitative setting method of each process of pre-spinning. Background technique [0002] In the pre-spinning process of ring spinning, the basis weight of the semi-finished products in each process of the traditional spinning process is mostly set relatively light, especially when spinning yarns with high quality requirements, the light weight is generally used as the process configuration principle . Due to the lighter setting of each pre-spinning process, especially the lighter weight of the roving, there is a saying in the spinning experience that the draft ratio of the spun yarn should not exceed "one time per British count", that is, the yarn density per British count of the spun yarn. The expansion ratio is about doubled. For a long time, whether it is spinning theory or actual production, the identification of the...

Problems solved by technology

[0008] The use of light quantitative spinning in the whole process of pre-spinning restricts the production capacity of each spinning equipment in the pre-spinning process, which is not conducive to the saving of production and management costs such as the configuration of the pre-spinning equipment, electricity consumption, and labor.
