Bamboo fiber yarns and production method thereof

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.
