Abstract

The invention relates to the field of light and textile industry and discloses a cellulose-based regenerative rabbit hair medicine composite fiber and a preparation method thereof. The preparation method comprises the following steps of: a, removing impurities and cleaning low-grade rabbit hair and rabbit hair offcuts; b, decomposing low-grade rabbit hair and rabbit hair offcuts subjected to impurity removal and cleaning with the dry weight of 8 to 15 parts in solution of sodium hydroxide with the dry weight of 100 parts and the concentration of 4 to 6 percent so as to obtain dissolved solution; c, adding dandelion nanopowder particles with the dry weight of 0.5 to 1 part into the dissolved solution, and uniformly stirring to obtain rabbit hair medicine protein fluid; and d, respectively filtering, defoaming and metering the rabbit hair medicine protein fluid and cellulose stock solution, spinning and forming through a core shell type composite spinning hole, and solidifying the formed fiber to obtain precursors for textiles. The cellulose-based regenerative rabbit hair medicine composite fiber has the advantages of wide raw material source, low cost, excellent performance, anti-inflammatory and bacteriostatic effects and extremely high application value.

Description

technical field [0001] The invention relates to the field of light industry and textiles, in particular to a cellulose-based regenerated rabbit hair medicinal composite fiber and a preparation method thereof. Background technique [0002] my country's rabbit hair resources are very rich, and the production area is very vast, concentrated in Zhejiang, Shandong, Jiangsu, Anhui, Henan and other places, with an annual output of about 18,000 tons, ranking first in the world. The export of rabbit fur and semi-finished products or finished products is one of the main commodities in which my country's export earnings exceed 100 million yuan, making a significant contribution to my country's economic development. [0003] Most of the high-quality rabbit down is exported directly, and a small part is made into rabbit fur textiles. However, the utilization rate of low-grade rabbit down and rabbit hair spinning waste that cannot be spun is very low, and most of them are discarded or bu...
