Problems solved by technology

Although the method of using deodorant and antibacterial finishing agent after dyeing and finishing does not affect the mechanical properties of the fiber material, the bonding force between the deodorizing and antibacterial finishing agent and the fiber substrate is weak, and the durability and washability are not good. When inorganic materials are used as deodorizing and antibacterial components, it will also affect the softness and touch of the fabric, reducing the use experience

Abstract

The invention belongs to the technical field of functional fiber materials, and discloses compound deodorizing, antibacterial and antiviral multifunctional fiber and a preparation method thereof. PVA and an organosilicon quaternary ammonium salt antibacterial agent are added into a traditional Chinese medicine antiviral extracting solution to obtain a mixed solution, then a catalyst and a sodium silicate or silicate ester compound are added for a condensation reaction, PVA-SiO2 interpenetrating network particles coating a traditional Chinese medicine antiviral component and the organosilicon quaternary ammonium salt antibacterial agent are obtained, and the obtained functional particles and a fiber matrix are subjected to mixed spinning, so that the product is obtained. The PVA is used as a coating agent of the traditional Chinese medicine antiviral component and the organosilicon quaternary ammonium salt antibacterial agent, so that mixing and dispersion of the traditional Chinese medicine antiviral component and the organosilicon quaternary ammonium salt antibacterial agent in the fiber matrix are promoted; and further an interpenetrating network enhanced structure is formed with SiO2. The long-lasting deodorizing, antibacterial and antiviral effects can be achieved and the fiber strength can be enhanced by introducing the multifunctional fiber into the fiber matrix.

Description

technical field [0001] The invention belongs to the technical field of functional fiber materials, and in particular relates to a compound deodorizing, antibacterial and antiviral multifunctional fiber and a preparation method thereof. Background technique [0002] Textiles will be stained with a lot of sweat, sebum and other human secretions during the wearing process of the human body. At the same time, they will also be contaminated by dirt in the environment. These dirt are good nutrients for various microorganisms, and the proliferation of microorganisms And decompose the dirt on the fabric to produce irritating gases such as ammonia, resulting in abnormal irritation to the skin. [0003] The method of adding antibacterial substances to prevent the generation of odor is called deodorization processing; the method of fabric surface treatment to eliminate the generated odor is called deodorization processing. There are two methods for processing deodorant and antibacteri...
