Technical Field
The invention relates to the technical field of antibacterial materials, in particular to a cellulose fiber and application thereof.
Background
In recent years, with the improvement of economic development level, people do not meet the basic requirements of warmth retention and comfort any more, but expect that the textile has new additional functions, such as health care and safety functions of antibiosis, deodorization, mite prevention, negative ion, ultraviolet prevention, radiation protection, far infrared, flame retardance, water and oil repellency, fragrance and the like. The biomass textile is an important textile, can meet the requirements of people on the diversity and functionality of the textile while meeting the requirements of low-carbon economy, sustainable development and regulation, and can meet the requirements of various industries for use.
Biomass textiles can be classified into biomass primary, biomass regeneration, and biomass synthesis, depending on the source of the raw material. Such textiles can be used in apparel, hats, and yarns; can also be used for bed sheets, quilt covers and tablecloths; it can also be used for tent, tyre, filter membrane and geotextile, etc. The biomass synthetic fiber is characterized in that the biomass synthetic fiber mainly comprises polytrimethylene terephthalate (PTT) fiber and polylactic acid (PLA) fiber, the PTT fiber is widely applied, and the conventional fiber material is not ideal enough in the aspect of antibiosis and has limited development in the field of antibiosis, so the biomass synthetic fiber is prepared by the scheme.

Detailed Description
PLA/PHBV fiber (cellulose fiber) is based on two bio-based degradable high polymer resins-polylactic acid (PLA) and 3-hydroxybutyric acid/valerate (PHBV), and is prepared by rheology modification, reactive blending and melt spinning, the fiber antibacterial and antiviral mechanism is that PHB with low polymerization degree is contained in the fiber, the fiber antibacterial and antiviral mechanism can destroy the biological membrane and cell wall of virus and microorganism, the content leaks out and enters the cell to change acid-base balance, so that the metabolism is unbalanced, and the fiber dies, the fiber surface has oligomer with certain concentration through process control, so that the strong antibacterial and antiviral effect is achieved, therefore, the cellulose fiber has the four advantages of pure natural bio-based, super-efficient antibacterial and antiviral, biodegradable and food grade, and is very consistent with the sustainable development concept of nature, safety, low carbon and environmental protection.
The antibacterial and antiviral properties of the cellulose fibers are the inherent properties of the materials, the cellulose fibers are stimulated to release antibacterial properties through complex process control, once the cellulose fibers are spun, the antibacterial and antiviral properties of the cellulose fibers can be maintained for a long time and cannot be obviously reduced due to multiple times of use or washing, and the cellulose fibers have the characteristics of long-acting antiviral and antibacterial properties, low carbon emission, degradability, sustainable regeneration, biocompatibility, biosafety and the like.
He plain KN95 mask (without any antibacterial and antiviral treatment): the mask is composed of four layers of non-woven fabrics, wherein one layer is a cellulose antiviral antibacterial base fabric, and the mask is detected by a microbiological analysis and detection center in Guangdong province: the antiviral activity rate of the compound has 99.11 percent on H1N1 influenza A virus, 99.39 percent on H3N2 influenza A virus, 99 percent on Escherichia coli, 99 percent on Candida albicans and 81 percent on staphylococcus aureus.
