Abstract

The invention provides poria cocos cellulose fiber. The poria cocos cellulose fiber is prepared by mixing a cellulose spinning stock solution with poria cocos extract, wherein the mass percent of poria cocos extract in the poria cocos cellulose fiber is 8-15%. The invention further provides a preparation method of the poria cocos cellulose fiber. The content of poria cocos extract is 8-15%, the dry fracture strength is 1.8-2.5 cN / dtex, the wet fracture strength is 1.36-1.56 cN / dtex, the dry fracture elongation rate is 18.5-22.8%, the residual sulfur content is as low as 4.8-6.2 mg / 100g, the ultralong fiber rate is smaller than or equal to 1.0%, and the dry fracture strength coefficient of variation (CV) is smaller than or equal to 12%; the dust mite phobotaxis is good, the phobotaxis rate reaches 93-99%, the antibacterial effect is good, and the poria cocos release period is long.

Description

technical field [0001] The invention relates to a poria cocos cellulose fiber and a preparation method thereof, belonging to the field of fiber preparation. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, people's pursuit of material and spiritual life, especially the concept of clothing, is also constantly changing, and people are paying more and more attention to the comfort and functionality of textiles. Traditional cotton, hemp, silk, wool and other natural fibers are affected by factors such as themselves and natural climate, grain and cotton competition for land, etc., the functionality and output of the fibers are far from meeting the actual needs. [0003] At present, one of the main sources of bulk fiber is underground non-renewable petrochemical resources such as petroleum and coal, and the other is renewable resources such as cotton, hemp, silk, and wool that are planted and farmed on l...
