Abstract

The invention discloses modified nano-zinc oxide, and discloses a preparation method and application of the modified nano-zinc oxide in preparing a fabric finishing agent for finishing fabrics. According to the modified nano-zinc oxide, the nano-zinc oxide is taken as a core, has good ultraviolet shielding property and excellent antibacterial and bacteriostatic properties, can endow a fabric with the functions of sun protection, antibiosis, deodorization and the like after being added into the fabric, and can provide wrinkle resistance and washing resistance at the same time. After modification, the anti-ultraviolet effect is improved, the elasticity and durability of the material are enhanced, meanwhile, the usable range of the material is widened, and the antibacterial performance is improved. The preparation method is simple and easy for large-scale production and use. The modified nano-zinc oxide prepared by the invention is used as a fabric finishing agent for finishing fabrics, the ultraviolet-proof performance, the tensile property and the toughness of the finished fabrics can be greatly improved, and the service life of the fabrics is prolonged.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a modified nano-zinc and its preparation method and application. Background technique [0002] With the development of technology and the continuous progress of society, while people's living standards have been greatly improved, their requirements for quality of life are also getting higher and higher. Today, when the global environment is destroyed, returning to nature and returning to nature has become an important standard for people to measure the quality of life, and people are increasingly pursuing the versatility of fabrics. In the open-air environment, ultraviolet rays can cause great damage to human skin. In high-intensity or long-term outdoor life, the skin will cause various problems due to ultraviolet rays, and even cause cancer. [0003] At present, there are two main technical methods for making anti-ultraviolet fabrics in the market: one is to mix an...
