Sub-micron filament belt spun yarn forming device and method for covering surface hairness of yarn body

Abstract

The invention relates to a sub-micron filament belt spun yarn forming device and method for covering the surface hairiness of a yarn body. An electrospun sub-micron filament film belt roll disposed atthe upper end of a ring spinning machine is unwound by an active unwinding frame to produce a sub-micron filament film belt; the sub-micron filament film belt justly fits to the edge fiber of a spinning triangular zone by the limiting and adjustment of a guide wheel, and the upward transfer of the twist enables the surface of a staple fiber ring spun yarn to be tightly coated with the sub-micronfilament film belt with a smooth surface, so that a ring spun yarn with less hairiness or free of hairiness can be processed. The technical bottleneck of difficulty in reducing the hairiness of the ring spun yarn is broken through by coating the short fiber yarn body with the flexible sub-micron filament film belt, the processing of the ring spun yarn which can be woven without sizing is expectedto be realized, the problems of environmental pollution and energy consumption caused by sizing can be solved, and the device and the method have 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
