Yarn forming device and method for submicron long ribbon with hairiness covering yarn body surface

Abstract

The invention relates to a device and method for spinning a submicron filament tape with hairiness covering the surface of a yarn body and a yarn forming method. The electrospun submicron filament film tape package arranged at the upper end of a ring spinning machine is unwound by an active unwinding frame. The submicron filament film belt, through the limit adjustment of the guide wheel, the submicron filament film belt just fits on the edge fiber of the spinning triangle area, and the upward transmission of the twist makes the smooth surface of the submicron filament film belt tight Coated on the surface of spun ring spun yarn, thereby processing ring spun yarn with little hairiness or even no hairiness. The present invention breaks through the technical bottleneck that the hairiness of ring-spun yarns is difficult to reduce through the method of spinning and coating staple fiber yarns with flexible submicron filament film belts, and is expected to realize the processing of ring-spun yarns that can be woven without sizing , can solve the problem of environmental pollution and energy consumption caused by sizing, and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of textile processing, in particular to a device and method for spinning a submicron long ribbon with hairiness covering the surface of a yarn body. Background technique [0002] Yarn hairiness refers to the fibers that protrude beyond the main contour of the yarn body. Generally, hairiness exceeding 3mm is considered harmful hairiness. This is because the hairiness of more than 3mm will lead to the loss of yarn strength, resulting in unclear opening and broken ends of the yarn during weaving, affecting the appearance of the fabric and other problems, especially the unclear opening and broken ends of the yarn during weaving will significantly reduce the weaving efficiency. and fabric quality. The most widely used ring spinning method is easy to form yarn hairiness or even harmful hairiness because the edge fibers at the spinning triangle area are uncontrolled and difficult to twist into the interior of the ...

AI Technical Summary

Problems solved by technology

[0006] The technology provided by the above invention can indeed significantly reduce yarn hairiness, but the energy consumption in the spinning process is high, and although the hairiness of the prepared yarn is greatly reduced, the sizing process is still required before subsequent weaving
