BAMBOO CHARCOALVISCOSE FIBRE AND PREPARATION METHOD THEREFOR

摘要

The present invention provides bamboo charcoalviscose fibres and a preparation method therefor. The fibres are obtained by blending a bamboo charcoal slurry and viscose and then spinning, wherein the content of nanometer bamboo charcoal is 0.1％-10％ of the weight of the finished fibres; the specific criteria of the finished bamboo charcoalviscose fibres comprise: dry breaking strength of 1.6-3.5 cN/dtex; dry breaking elongation of 16-20％, dry strength variable coefficient of CV≤18％, dry breaking elongation variation coefficient of CV≤8％, defects ≤ 4 mg/100, a content of bamboo charcoal of 0.1-10％, an antimicrobial ratio ＞99.9％, an ammonia adsorption ＞50％, and colour fastness to washing of 4-5 level. The finished fibres prepared in the present invention has properties such as high strength, good adsorbability, an excellent antimicrobial effect, a uniform colour and strong fixation, and provide a bamboo charcoalviscose fibre raw material with good quality for preparing textiles.
