Spinneret plate for cotton and flax blended hollow and thick spun filaments

Abstract

The invention discloses a spinneret plate for cotton and flax blended hollow and thick spun filaments, and belongs to the field of spinning blending. The spinneret plate for the cotton and flax blended hollow and thick spun filaments comprises a spinneret plate body with a plurality of spinneret orifices uniformly formed in the surface, micro air spinning frames are arranged on the inner sides ofthe spinneret orifices and located on the large-orifice-diameter sides of the spinneret orifices, and the micro air spinning frames comprise air spinning impacting heads and multiple air spinning frame fixed wings; when passing through the micro air spinning frames, a blending raw material is turned into hollow filaments under the effect of air spinning impacting heads, under the heating effect ofthe air spinning impacting heads, the inner walls of the hollow filaments are ironed, so that the inner walls of the hollow filaments are smooth and have certain elasticity, and it is ensured that the hollow filaments are not easily deformed in the later period; the partial portions of the blending raw material with formation of the hollow filaments are roughened by the surfaces of the air spinning frame fixed wings, in the process that the blending raw material continues to pass through the trumpet-shaped spinneret orifices, through a filament outlet area gradually becoming small from a large shape, the roughened portions on spinning threads are extruded mutually, the bonding degree is higher, and the spinning threads are not easily broken in the later use process.

Description

technical field [0001] The invention relates to the field of textile blending, and more specifically relates to a hollow coarse spinning spinneret for cotton and flax blending. Background technique [0002] Blended or blended chemical fiber fabrics are textile products made of chemical fibers mixed with other cotton wool, silk, hemp and other natural fibers. It has both the style of polyester and the advantages of cotton fabrics, such as polyester cotton cloth and polyester wool gabardine. Blending is divided into wool-viscose blending, sheep and rabbit wool spinning, TR fabrics, high-density NC fabrics, 3M waterproof mousse fabrics, TENCEL fabrics, Rousai silk, TNC fabrics, composite fabrics, etc. [0003] Blended cotton is one of the characteristic cotton fabrics. It is a natural fiber fabric, which is not only comfortable, cool and breathable, but also has the advantages of soft color matching, good drape and small shrinkage. There are linen-cotton blended fabrics, Linen...

AI Technical Summary

Problems solved by technology

[0005] The blended fabrics obtained in the above scheme include most of the existing blended fabrics. In order to ensure the strength of the fabrics, the textile threads are all solid, and the amount of textile materials is large, especially some rough textile threads. The finished product is relatively heavy. In the existing textile technology, although there are textile threads such as hollow yarns, such hollow textile threads are easily deformed when squeezed, and the toughness of the textile thread itself is also poor, and the wire tube is easy to break.
