Preparation method and applications of isatis root extract, vitamin and protein composite microcapsule

Abstract

The invention belongs to the technical field of functional cellulose fiber, and relates to an isatis root extract, vitamin and protein composite microcapsule, which is used to prepare isatis root cellulose fiber. The preparation method comprises the following steps: adding isatis root extract and vitamins into a water solution of emulsifier, carrying out shearing emulsification to obtain a mixed emulsified solution; adding the mixed emulsified solution into a gelatin solution, then adding an Arabic gum solution, evenly mixing to form stable oil-in-water emulsion; adjusting the pH value, heating and stirring to carry out complex coacervation to obtain suspension liquid; cooling the suspension liquid, adding a curing agent, adjusting the pH value to carry out crosslinking reactions, after reactions, filtering to obtain isatis root extract, vitamin and protein composite microcapsules; adding the composite microcapsules into viscose stock solution to prepare a blended spinning liquid, and carrying out spinning through an adjusted coagulation bath. Through the micro-encapsulation, crosslinking and solidification, the loss of effective component during the processes of spinning and post treatment is reduced, and the prepared viscose has the antivirus and skincare functions.

Description

technical field [0001] The invention belongs to the technical field of functional cellulose fibers, and specifically relates to a composite microcapsule of Radix Radix Radix Radix-Vitamin as the core material and gelatin as the wall material, and is used for preparing microcapsules with anti-virus, skin care and health care Preparation method of functional isatidis cellulose fiber. Background technique [0002] Health and environmental protection is one of the most concerned topics in today's society. In recent years, the textile industry has introduced many fibers and textiles with health care and medical functions that are beneficial to human health and environmental protection. After years of development, health-care fibers and their textiles have achieved gratifying results in both technology development and product development, including the direct integration of vitamins into women's shirts and T-shirts containing rheumatoid drug particles. These textiles with both f...

[0003] Chinese patent ZL201010592931.7 discloses a preparation method of pearl traditional Chinese medicine fiber with skin care and health care functions. The fiber is composed of 90-95% cellulose fiber, 2-5% pearl and 2-5% traditional Chinese medicine. The traditional Chinese medicine is Notoginseng, Angelica, Salvia miltiorrhiza, any one or more combinations; in the preparation process of the fiber, the pearl powder and traditional Chinese medicine components are prepared into a slurry and then directly added to the spinning slurry, mixed and filtered , spinning, drawing, and setting to make pearl traditional Chinese medicine fiber; since chemical raw materials such as sodium hydroxide, carbon disulfide, and sulfuric acid are used in the production process of viscose fiber, pearl powder, Chinese medicine group and so on are used in the fiber production process. The branch will be damaged, seriously affecting the functionality of the fiber

Chinese patent ZL201310140966.0 discloses a viscose fiber with plant-derived antibacterial function and mint aroma. When spinning, the antibacterial agent solution and peppermint oil microcapsules are added to the viscose liquid, stirred evenly, and left to stand for vacuum defoaming to obtain Viscose spinning solution; the resulting viscose spinning solution is introduced into a coagulation bath for spinning and forming, and the filaments are drawn to obtain filaments; in this patent, Radix isatidis extract is used, but the extract of Radix isatidis has not been protected and modified. Directly added to the viscose collagen solution, the Radix isatidis is damaged and lost during the spinning process, which affects the functionality of the fiber
