Abstract

The invention provides procyanidine cellulosic fiber. The procyanidine cellulosic fiber is prepared by blending a spinning stock solution with procyanidine, wherein the mass percentage of procyanidine is 9-12%. The invention further provides a preparation method of the fiber. The prepared fiber is good in mechanical performance and low in residual sulfur content; the mite expelling rate reaches 92.6-97.8%; after 50 times of washing, the mite expelling rate reaches 88.2-94.2%; the antibacterial performance is good; the slow release period of procyanidine is long and reaches 1-1.6 years; the ultraviolet resistance is high, after 40 times of washing, the ratio T of the spectrum transmission of the regenerated cellulosic fiber in the waveband UVB to the spectrum transmission of the regenerated cellulosic fiber in the waveband UVA is 2.1-3.0%, and after 40 times of washing, the ultraviolet protection factor (UPF) reaches 30-55.

Description

technical field [0001] The invention relates to a proanthocyanidin 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...
