Problems solved by technology

Among them, the more representative biomass synthetic fibers mainly include polypropylene terephthalate (PTT) and polylactic acid (PLA) fibers. The latter is more widely used, and the current existing fiber materials are not good enough in terms of antibacterial performance. Ideal, with limited development in the field of antimicrobials, hence the case

Embodiment Construction

[0023] PLA / PHBV fiber (grass fiber) is based on two biodegradable polymer resins-polylactic acid (PLA) and 3-hydroxybutyric acid / valerate (PHBV), through rheological modification, reactive blending and Prepared by melt spinning, the antibacterial and antiviral mechanism of the fiber is that it contains PHB with a low degree of polymerization, which can destroy the biofilm and cell wall of viruses and microorganisms, make the contents leak out, and enter the cells to change the acid-base balance and cause metabolism. Imbalance, so that it will die, we control the process, so that the surface of the fiber has a certain concentration of oligomers, so as to achieve a strong antibacterial and antiviral effect, so the above-mentioned grass fiber has pure natural bio-based, super effective antibacterial and antiviral, The four advantages of biodegradable and food grade are in line with the sustainable development concept of natural, safe, low-carbon and environmental protection.

Abstract

The invention provides a PLA / PHBV fiber which is prepared from two biodegradable polymer resins, namely polylactic acid and 3-hydroxybutyrate / valerate through rheological modification, reactive blending and melt spinning. The PLA / PHBV fiber can be applied to antibacterial products such as antibacterial and antiviral masks, PLA / PHBV antibacterial socks, PLA / PHBV antibacterial wool bath towels and PLA / PHBV antibacterial underwear. The PLA / PHBV fiber is natural, safe, low in carbon and environmentally friendly. The invention further provides application of the PLA / PHBV fiber.

Description

technical field [0001] The invention relates to the technical field of antibacterial materials, in particular to a grass fiber and its application. Background technique [0002] In recent years, with the improvement of the level of economic development, people's requirements for textiles no longer meet the basic requirements of warmth and comfort, but hope that textiles have new additional functions, such as antibacterial, deodorant, anti-mite, negative ions, anti-ultraviolet, Radiation protection, far infrared, flame retardant, water and oil repellency and fragrance and other health care and safety functions. Among them, biomass textiles are an important class of textiles. While meeting the low-carbon economy and sustainable development regulation, they can also meet people's needs for fabric diversity and functionality, and can also meet the requirements of various industries. [0003] According to different sources of raw materials, biomass textiles can be divided into t...
