Abstract

The invention discloses a preparation method and an application method of a magnesium peroxide antibacterial agent. The method comprises the following steps: adding magnesium chloride hexahydrate into a hydrogen peroxide solution, stirring until magnesium chloride is completely dissolved, and adding a NaOH solution dropwise while stirring until synthesis of insoluble magnesium peroxide is completed; filtering the generated magnesium peroxide by filter paper, and using clear water to wash impurities adsorbed on the magnesium peroxide product; transferring the cleaned magnesium peroxide from the filter paper to a glass surface vessel and drying to finish preparation of the magnesium peroxide; grinding the synthesized magnesium peroxide antibacterial agent into powder, mixing the powder and acrylamide in an aqueous solution uniformly, and preparing finishing liquid under ultrasonic treatment; soaking fibers in the finishing liquid, performing roll compacting on a padder, drying for a certain time and performing high-temperature solidification to finish cross linking; and washing the finished fiber with water. The preparation method and the application method of the magnesium peroxide antibacterial agent have the beneficial effects of high antibacterial property and no influence on the original wearability of textiles.

Description

technical field [0001] The invention belongs to the technical field of textile chemistry, and relates to a preparation method and an application method of a magnesium peroxide antibacterial agent. Background technique [0002] Ordinary textiles have no inhibitory effect on microorganisms such as bacteria or fungi. For a long time, traditional textiles have been considered as good media for microbial growth. grow, reproduce. The existence of bacteria on textiles will not only affect the performance of textiles, but also bring a series of adverse effects to consumers. The growth of microorganisms on textiles can lead to functional, hygienic and aesthetic problems. For example, unpleasant odors on intimate clothing such as socks, the spread of germs, soiling and degrading textiles are all undesirable effects of microbial attack. At the same time, bacteria and fungi bring many problems such as fading, staining and fiber damage to textiles [6]. Therefore, in order to prevent ...
