Problems solved by technology

[0008] (2) If coated with microcapsules, the Radix isatidis microcapsules are also easy to lose
[0010] In the spinning process, when the blended solution of viscose spinning stock solution and isatis root microcapsules is sprayed into the coagulation bath, the first fiber begins to form, and then covers the added microcapsules, but the viscose spinning stock solution The substance that can be cured and formed, that is, the content of methyl fiber is less than 10%. There are very few microcapsules that can be covered by methyl fiber during the molding process. Water, soluble salts and other substances are lost, resulting in a large loss of Radix isatidis microcapsules

Abstract

The invention provides viscose fiber containing a radix isatidis extract. According to the viscose fiber, the content of radix isatidis microcapsules is 9.1%-9.79%, the dry fracture strength of the fiber is 2.70cN / dtex-2.75cN / dtex, the wet fracture strength of the fiber is 1.70cN / dtex-1.75cN / dtex, the elongation at break of the fiber is 22%-23%, the antibacterial rate of the fiber to staphylococcus aureus is 99.0%-99.8%, the antibacterial rate of the fiber to Candida albicans is 96.6-98.8%, the antibacterial rate of the fiber to typhoid bacillus is 97.2%-99.1%, and the fiber has very strong effects of inhibiting and killing influenza A virus and influenza B virus. The invention further provides a preparation method of the viscose fiber containing the radix isatidis extract. The preparation method comprises a step of modifying the radix isatidis microcapsules. According to the preparation method, the loss of the radix isatidis microcapsules in the preparation process of the fiber is reduced, the dismantling backwashing rate of a coagulating bath filter is reduced, and the distribution uniformity of the radix isatidis microcapsules in the fiber is increased.

Description

technical field [0001] The invention relates to a viscose fiber, in particular to a viscose fiber containing Radix isatidis extract and a preparation method thereof, belonging to the technical field of textiles. Background technique [0002] The development of functional fibers is a symbol of the progress of modern fiber science. The development of functional fibers, differential fibers and high-performance fibers has created favorable conditions for the technological innovation of the traditional textile industry and the transformation to high-tech industries, and has contributed to the improvement of human living standards. Functional fiber refers to a new type of fiber that has some special function in addition to the physical and mechanical properties of ordinary fibers. [0003] Radix isatidis is an excellent Chinese herbal medicine, which has antibacterial, anti-virus, anti-tumor, and immune-enhancing functions; the extract of Radix isatidis is added to viscose fibe...
