Antibacterial coating slurry and use method thereof

Abstract

The invention discloses antibacterial coating slurry for a fiber fabric and a use method of the antibacterial coating slurry. The antibacterial coating slurry comprises the following components in percent by weight: 1.5%-3.5% of an antibacterial agent, 0.1%-0.15% of a dispersant, 15%-25% of a waterborne acrylic emulsion, 5%-6.5% of a thickening agent, 0.1%-0.2% of a color fixing agent, and the balance of water, and the sum of the content of each component is 100%, wherein the antibacterial agent is a submicron-grade TiO2-Ag antibacterial agent. Aiming at overcoming the defects of the prior art, the invention provides an antibacterial finishing slurry composition which can be used for antibacterial treatment of fabrics, so that an antibacterial fabric with broad-spectrum antibacterial capability is obtained, and the prepared antibacterial fabric is effectively prevented from discoloration.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to an antibacterial coating slurry and an application method thereof. Background technique [0002] With the enhancement of people's self-care awareness, there are higher requirements for the antibacterial properties of durable consumer goods such as hygiene products, daily necessities, water treatment devices, food packaging, and clothing. Products that add antibacterial agents to prevent microbial reproduction have begun to be favored by consumers. . [0003] At present, the antibacterial agents used at home and abroad are divided into two categories according to the structure: inorganic antibacterial agents and organic antibacterial agents. Although inorganic antibacterial agents have long-lasting antibacterial effects, good acid and alkali resistance, washing resistance, light and heat resistance, they are prone to color change, and must be made into ultrafi...

AI Technical Summary

Problems solved by technology

Although inorganic antibacterial agents have long-lasting antibacterial effects, good acid and alkali resistance, washing resistance, light and heat resistance, they are prone to color change, and must be made into ultrafine powders to be evenly distributed on the surface of the product, and they are selective to the carrier; although organic antibacterial agents are easy to Dispersed and mixed, not easy to change color, but not heat-resistant, bacteria may develop resistance to it, and the decomposition products of some organic antibacterial agents have certain toxic and side effects

[0004] Compared with organic antibacterial agents, inorganic antibacterial agents have advantages in terms of safety, durability, heat resistance, etc., but most of the inorganic antibacterial agents on the market currently use silver ions as antibacterial components. It is easy to change from white to dark brown in the air. Most of the prior art can only deal with dark-colored fabrics, so that the discoloration of silver is not obvious, and it cannot deal with light-colored, pure white fabrics, which requires both antibacterial and beautiful appearance. The application of the fabric is limited

Secondly, the antibacterial effect on fungi is poor, and the antibacterial agent cannot be stably fixed on the textile, and the washability is poor, so it cannot well meet the requirements of practical applications.
