Red yeast rice extract modified protein/cellulose composite fiber and preparation method thereof

Abstract

The invention provides a red yeast rice extract modified protein / cellulose composite fiber. The mass content of the fiber and a red yeast rice extract is 0.95%-1.86%, and the mass content of protein is 4.85%-9.75%. The invention also provides a preparation method of the fiber. The preparation method comprises the following steps: preparing a red yeast rice extract modified protein micro-powder dispersion liquid, preparing a blended spinning stock solution, spinning and carrying out aftertreatment. The fiber prepared by the invention contains 0.95%-1.86% of red yeast rice extract and 4.85%-9.75% of protein; the dry breaking strength of the fiber is 2.3-2.5 cN / dtex, the wet breaking strength of the fiber is 1.25-1.4 cN / dtex, and the dry breaking elongation of the fiber is 16-22%; and meanwhile, the fabric made of the fibers has good moisture absorption and quick drying properties.

Description

technical field [0001] The invention relates to a health-care fiber and a preparation method thereof, in particular to a kind of red yeast rice with skin-friendly and health-care functions prepared by using protein micropowder as a carrier of red yeast rice extract and blending wet spinning technology An extract modified protein / cellulose composite fiber and a preparation method thereof belong to the technical field of textiles. Background technique [0002] With the development of technology and the improvement of people's living standards, the concept of great health is deeply rooted in the hearts of the people. Safe, comfortable and functional textiles are increasingly becoming a development demand, and the role of traditional Chinese medicine in physical therapy and health care is accepted by more and more people. Taking medicine for treatment, Transformed into clothing protection, functional health care textiles are loved by many consumers. [0003] Chinese patent ZL20...

AI Technical Summary

Problems solved by technology

This technology directly adds the ingredients of traditional Chinese medicine to the spinning stock solution for spinning. Although the effective ingredients of traditional Chinese medicine are retained in the fiber and has certain health care functions, the traditional Chinese medicine is easily damaged in a strong acid and alkali environment without protection. There are also problems such as weak binding between the extract and cellulose, and poor washing resistance of subsequent fabrics.

[0004] Chinese patent ZL201110400581.4 adds nanoscale animal micropowder protein dispersion liquid into denatured viscose and stirs evenly to prepare animal micropowder blended viscose, which is degassed and filtered, and then spun to form animal micropowder protein Viscose fiber, but there are defects that protein is easy to lose and not resistant to washing

[0006] During the preliminary test, the applicant found that when the red yeast rice extract and protein powder were added to the viscose spinning solution for spinning to prepare composite fibers, there was a technical problem that the red yeast rice extract and protein powder were easy to lose, and at the same time, they were resistant to washing. poor performance
