Abstract

The invention provides Lyocell fiber containing wormwood / radix isatidis / tea and a preparation method thereof. The Lyocell fiber is characterized in that the Lyocell fiber is prepared by modifying porous molecular nests containing wormwood / radix isatidis / tea extract and polyvinyl alcohol (PVA), wherein the addition amount of the wormwood / radix isatidis / tea extract in the porous molecular nests in the production process accounts for 1-5wt% of the total amount of cellulose and polyvinyl alcohol raw materials, and the ratio of the addition amount of the polyvinyl alcohol (PVA) to the addition amount of cellulose is 1:9-1:1. The preparation method comprises the following steps that S1, plant extract is prepared; S2, the porous molecular nests are prepared; S3, a porous molecular nest PVA adhesive film is prepared; and S4, the composite Lyocell fiber is prepared. According to the preparation method, natural effective components of the wormwood, the radix isatidis and the tea with bacteriostatic, antiviral and antioxidant effects are introduced into the fiber, so that the fiber has good antibacterial effect and biocompatibility, and is very suitable for special textile materials for medical treatment and health care.

Description

technical field

[0001] The invention relates to the field of fiber technology, in particular to a composite Lyocell fiber containing plant functional porous molecular nests of wormwood, isatis root and tea extract and a preparation method thereof. Background technique

[0002] Lyocell fiber is a kind of cellulose fiber prepared by dissolving natural fiber pulp such as wood, cotton, bamboo, etc. in organic solvent N-methylmorpholine-N-oxide, and spinning through dry jet wet spinning. It has dry strength and It has the advantages of high wet strength, good washing stability, excellent hygroscopicity and soft hand feeling. In addition, Lyocell fiber uses natural renewable cellulose resources and the spinning process is simple and clean. Therefore, it is recognized as a new type of green fiber material with excellent performance. The technology develops rapidly and is favored by consumers and widely used in various fields.

[0003] In particular, its high wet strength makes it ...
