Abstract

The invention relates to regenerated cellulose fiber containing Binchotan and a preparation method of the regenerated cellulose fiber. The regenerated cellulose fiber containing the Binchotan, provided by the invention, is characterized in that Binchotan powder, regenerated celluloses and the like are adopted as raw materials, Binchotan dispersing liquid is formed by uniformly dispersing the Binchotan powder in water, a viscose spinning solution is prepared simultaneously, and a pre-spinning injection method is adopted to add the Binchotan dispersing liquid into the viscose spinning solution for spinning, thereby obtaining a finished product. The regenerated cellulose fiber containing Binchotan and the preparation method of the regenerated cellulose fiber provided by the invention have thebenefits: in the regenerated cellulose fiber containing the Binchotan, the adding amount of the Binchotan is 1.5-10 percent by weight of alpha-celluloses, the ammonia absorption rate is more than orequal to 50 percent, the air permeability is more than or equal to 600 mm / s, the washing resistance is realized, and the color fastness is grade 4-5. The regenerated cellulose fiber provided by the invention has an antibacterial rate of 95 percent, a remarkable antibacterial effect, a far infrared emissivity of 88.5 percent, a remarkable far infrared emission function, an ammonia adsorption rate of more than or equal to 50 percent and a remarkable deodorization function; a prepared textile product has the characteristics of being smooth, fine and good in hygroscopicity.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a regenerated cellulose fiber and a preparation method thereof, in particular to a regenerated cellulose fiber containing binchotan charcoal and a preparation method thereof. Background technique [0002] The textile industry is a traditional industry in China. With the rapid development of clothing, household and industrial textiles, the differentiation and individualization of textile products have become the focus of the development of various enterprises. Functional fibers as high-grade textile raw materials are generally improved by means of physical modification, chemical modification and molecular design to obtain fibers with specific properties, so that the original viscose fibers are stable in light and heat, conductive, Flame retardant, dyeing, antistatic, moisture absorption, fluffy, anti-pilling, anti-fouling and other aspects have been greatly improved. [0003] Rege...
