Abstract

The invention discloses a ginkgo biloba cellulose fiber and a preparation method thereof. The preparation includes the following steps: preparing the ginkgo biloba extract into slow-release microcapsules; preparing viscose by using cellulose pulp as a raw material, and preparing the ginkgo biloba extract into microcapsules The capsule emulsion is uniformly mixed with viscose by means of pre-spinning injection in a proportion of 1.0-12.0 wt % of the dry powder ginkgo biloba microcapsules in the finished fiber, using a mixer as a place to prepare ginkgo biloba antibacterial cellulose fibers. The ginkgo biloba antibacterial cellulose fiber of the invention is not only lighter to wear, the hygroscopicity and air permeability are further enhanced, but also the production process guarantees the effective components of the ginkgo biloba leaves to the greatest extent and avoids waste. The fibers produced have excellent wear performance, good textile processing performance, antibacterial and health care effects.

Description

technical field [0001] The invention relates to the technical field of modified cellulose, in particular to a ginkgo leaf antibacterial cellulose fiber and a preparation method thereof. Background technique [0002] At present, most of the viscose fiber varieties in my country are ordinary fibers, and there are few functional fibers and differentiated fibers. Although China has mastered the production technology of colored fiber, flame-retardant fiber and ultra-fine denier yarn, there are very few manufacturers with mass production capacity. [0003] Ginkgo biloba is the dry leaf of Ginkgo biloba, harvested in autumn when the leaves are still green. The extract extracted from Ginkgo biloba is a good natural antibacterial agent, which has been widely used in food, medicine, health care products, daily chemical industry and other fields. Ginkgo biloba extract is a non-volatile brown granular solid. Ginkgo biloba is sweet in nature, bitter in taste, astringent, flat, returns...
