1. Antibacterial and anti-ultraviolet performance: nano-zinc oxide under sunlight and ultraviolet irradiation, can decompose negatively charged electrons and positively charged holes, activate oxygen in the air into reactive oxygen species, and most organic matter (including organic matter in bacteria) oxidation reaction, thus killing most germs and viruses. This anti-bacterial and anti-ultraviolet properties make zinc oxide dispersion ideal for anti-bacterial and anti-ultraviolet treatment of textiles.
2.environmental protection: compared with traditional textile slurry such as PVA (polyvinyl alcohol) nano zinc oxide dispersion has a lower COD value (oxygen consumption), and better solubility, without high temperature cooking, thus reducing energy consumption and environmental pollution. The use of nano zinc oxide dispersion modified starch mixture to partially replace PVA is helpful to reduce the amount of PVA in pure cotton yarn sizing and alleviate the pollution of desizing wastewater to water ecological environment.
3.improve the performance of the slurry: the addition of nano-zinc oxide dispersion can significantly reduce the viscosity of the slurry, improve the fluidity and adhesion of the slurry, which is conducive to the spreading of the fiber, forming a close contact at the molecular level, and then improve the bonding strength. The addition of nanometer zinc oxide can also increase the breaking strength of yarn, reduce yarn hairiness index and improve yarn weaving ability.
4. Functional enhancement: zinc oxide dispersion not only provides antibacterial and anti-ultraviolet function, but also can adjust its performance according to needs through special processes, such as the introduction of modified nano zinc oxide, which can further enhance the antibacterial, bactericidal and washable resistance of textiles to meet the needs of specific application scenarios.
5. Cost effectiveness: Although the production cost of nano-zinc oxide dispersion may be slightly higher than that of traditional materials, considering the performance improvement and environmental benefits brought by it, its application in the textile industry is still cost-effective.
باختصار, the application of zinc oxide dispersion in textiles has the advantages of antibacterial and anti-ultraviolet, environmental protection, improvement of slurry performance, functional enhancement and cost-effectiveness.
