Bamboo fiber yarns and production method thereof

Abstract

The invention discloses bamboo fiber yarns and a production method thereof. The bamboo fiber yarns are prepared by spinning the following blended raw materials in part by weight: more than 5 and less than or equal to 95 parts of bamboo fibers (preferably 20 to 40 parts) and 60 to 80 parts of natural fibers (such as cotton) or environmentally-friendly differential fibers. The production method comprises the following steps of: blending slivers made of the bamboo fibers and the natural fibers (such as the cotton) or the environmentally-friendly differential fibers again; and drawing, roving, spinning and spooling for 2 to 3 times to prepare various blended bamboo fiber yarns with low bamboo fiber content, which have naturally antibacterial, bacteriostatic, anti-ultraviolet, hygroscopic, air-permeable characteristics and the like. A plurality of superfine grooves on the surfaces of the bamboo fibers contributes to the improvement on moisture absorption, so that the yarns have the function of dehumidifying. The production method has the advantages of uniqueness, effectiveness, easily controllable manufacturing process, basically no need of equipment replacement, low manufacturing cost and high production efficiency.

Description

technical field [0001] The invention relates to a yarn blended with natural fibers such as bamboo fibers and cotton or environmentally friendly differentiated fibers (mainly tencel and fine denier modal fibers) and a production method thereof. Background technique [0002] Bamboo fiber mainly uses mechanical and physical methods to directly separate and extract fibers from bamboo. It is a pure green and environmentally friendly natural fiber. The chemical components of bamboo fiber are mainly cellulose, hemicellulose and lignin. More than 90% of the quality, bamboo fiber has excellent performance, has a unique style, is quite good in consumption, and has remarkable health effects. Bamboo fiber can retain the characteristics of bamboo to the greatest extent, so it has excellent antibacterial and deodorizing properties. There are more voids in the fibers than cotton, the structure is looser, and moisture is easy to absorb, so it has excellent moisture absorption and moisture d...

Problems solved by technology

[0004] Spinnability of bamboo fiber: The existing bamboo fiber raw materials are tested, and the fiber length is distributed between 5mm and 100mm, and the length of the main body is concentrated in 15-40mm. The length uniformity is very poor, and the fineness is 2-4 times thicker than cotton. It also contains a small amount of short and thick fibers with different lengths and high rigidity. The cohesion of the fibers is poor, and hairiness is easy to occur during the manufacturing process. The overall rigidity of the fibers is relatively high, it is difficult to open and comb, and the draft control is difficult.
