Problems solved by technology

However, due to the small surface friction coefficient of cupro ammonia fiber and lyocell fiber, it is difficult to grasp when opening and clearing, and the cohesion between the two is poor, resulting in uneven mixing, resulting in easy sagging or breaking of the fiber web during blending, which is suitable for spinning Poor performance, needs to be improved urgently

Embodiment Construction

[0018] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0019] The preferred embodiment is a blended yarn. The blended yarn is composed of 24%-27% cupro fiber, 46%-50% lyocell fiber and 24%-27% by mass. 27% cotton fiber composition. This blended yarn takes advantage of the strong frictional properties of cotton fibers to bind cupro fibers and lyocell fibers with poor cohesion together, so that through three drawing processes of first, second and last drawing, as well as vortex spinning The resulting blended yarn has stable spinnability.

[0020] Preferably, the blended yarn is vortex spun by the final drawing frame 1, and the final drawing frame 1 is as figure 1 It is shown that it is formed by merging 6 second drawing frames 11, the second drawing frame 11 is formed by merging 6 first drawing frames 111, and the first drawing frame 111 is formed by two strands of cupro fiber 1112, four strands ...

Abstract

The invention discloses a blended yarn, which is formed by vortex spinning with 46%-50% lyocell fiber, 24%-27% cotton fiber and 24%-27% cupro ammonia fiber. The copper ammonia fiber and lyocell fiber are entangled on the cotton fiber with strong friction to obtain stable spinnability. At the same time, the blended yarn has a soft and natural luster due to the cupro ammonia fiber and lyocell fiber, and it feels soft and smooth Excellent texture, moisture permeability, air permeability and other characteristics, it is a relatively high-quality textile fabric.

Description

technical field [0001] The invention relates to high-grade textile fabrics, in particular to a blended yarn comprising cupro fiber and lyocell fiber. Background technique [0002] The cross-section of cupro fiber is round, without skin-core structure, the fiber can withstand high stretching, and the monofilament obtained is relatively thin, so the fabric feels soft, soft luster, and silk feeling. High-grade silk or knitted fabrics; cupro fiber has excellent wearing performance similar to silk, good hygroscopicity, great drape, conforms to the trend of environmental protection clothing, and single yarn is expensive. Lyocell fiber is a kind of natural fiber, which is made of pulp formed by mashing renewable bamboo, wood, etc. as raw material. The advanced technology makes its solvent recovery rate as high as 99.7%, which is not only energy-saving, environmentally friendly, but also sustainable. ; Clothes made of lyocell fiber not only have natural luster, smooth hand feeling,...
