[0005] Patent 201310505105.8 discloses an antibacterial viscose fiber containing mugwort oil and its production method. In this method, mugwort oil extracted from mugwort is dispersed in water to form an emulsion, which is then solidified and dried to form microcapsules powder, and this powder is added to the viscose spinning stock solution as an antibacterial agent to make antibacterial viscose fiber by conventional wet spinning. This method makes the antibacterial agent into microcapsules and adds it, although it can make the antibacterial component not easy to lose At the same time, it also delays the release of active ingredients and reduces the antibacterial effect. The fusion of antibacterial agents and viscose collagen solution is poor, which affects the curing effect and skin-friendly performance of fibers, and the use of cellulose pulp as a raw material for viscose has no effect on the mugwort itself. effective use of fiber
Patent 201510445903.5 discloses a preparation method of Artemisia argyi cellulose spinning dope. The method uses Artemisia argyi cellulose pulp raw material as the preparation of spinning solution. Using Artemisia argyi as a raw material mainly solves the current situation of viscose raw material shortage. In the process of meal preparation, sodium hydroxide, sodium sulfide, sodium hypochlorite and other strong alkaline or oxidative substances are used to cook and configure, the biological activity of the fiber itself will be greatly affected, and this method only prepares regenerated fibers that meet the spinning requirements , the biological activity of the fiber has not been verified

Abstract

The invention relates to a preparation method of Chinese mugwort fibers and belongs to the technical field of textile engineering. The preparation method takes Chinese mugwort raw leaves as raw materials and comprises the following steps: physically treating the raw materials and carrying out enzymolysis treatment; then mixing glucosan and adding a water solution of polyvinyl alcohol and a water solution of amine oxide to prepare a raw spinning solution; extruding the raw spinning solution through a nozzle by using an existing spinning technology; after extruding, enabling the solution to enter a water solution spinning bath containing the amine oxide through an air gap and curing to form filament yarns; and drying the cured filament yarns to obtain the Chinese mugwort fibers. The Chinese mugwort fibers provided by the invention can keep the biological activity of effective components in Chinese mugwort to the greatest extent, and the antibacterial, sterilization and anti-allergic effects of the fibers are good; and the Chinese mugwort fibers can be widely applied to the weaving of yarns, woven fabrics, braided fabrics or knitted fabrics.

Description

technical field [0001] The invention belongs to the technical field of textile engineering, and in particular relates to a preparation method of mugwort fiber. Background technique [0002] With the improvement of people's living standards and health awareness, better requirements have been put forward for the skin-friendly, breathable, anti-bacterial, and anti-allergic properties of textile products that are most in contact with daily. The function has a good protective and preventive effect on the human body. At present, the common fibers in the textile industry include natural fibers and chemical fibers. Natural fibers refer to natural fiber materials in nature, including plant fibers and animal fibers, such as cotton, ramie, wool, silk, etc. Although the materials are environmentally friendly and non-irritating to the skin, No harm, but there are also defects such as single functionality, fragile fibers, easy damage and discoloration; and chemical fibers are a general t...
