Multifunctional compound cellulose fiber and preparation method thereof

Abstract

The invention discloses a multifunctional compound cellulose fiber and a preparation method thereof. By adoption of an advanced microcapsule preparation technique and modification of a cellulose fiber solution preparation process, a cellulose fiber is modified through polyvinyl alcohol, herba centellae, proteins and vitamins to obtain the multifunctional compound cellulose fiber by means of a cellulose fiber wet spinning process. The multifunctional compound cellulose fiber prepared according to the method is capable of meeting people's demands on moisture absorption, bacteria resistance, skin caring and the like of fibers, and a product is excellent in physical and mechanical performance and stable functionally and has a promising development prospect.

Description

technical field

[0001] The invention belongs to the field of functional composite fiber materials, and in particular relates to a multifunctional composite cellulose fiber and a preparation method thereof. Background technique

[0002] Due to the excellent performance of cellulose fibers and their products, they have been widely used. Therefore, vigorously developing new varieties of cellulose fibers with high performance and differentiation is an important direction for the development of cellulose fibers. After years of development, functional composite fibers and Its textiles have achieved certain results.

[0003] In the existing technology, a series of high-performance and differentiated functional composite fibers have been developed, such as a high-strength moisture-absorbing fiber disclosed in the patent document CN201420080990.X. Through the special structure between fiber monofilaments, the fiber has excellent Excellent hygroscopic performance, long life of hygros...
