Abstract

The application relates to the field of textile materials, and specifically discloses an antibacterial fabric for a sofa cushion and a production process thereof. The antibacterial coating layer comprises the following parts by weight: 45-50 parts of deionized water, 3-5 parts of chitosan and 6-8 parts of modified antibacterial particles; the modified antibacterial particles are 200-300 mesh titanium dioxide particles. This application uses titanium dioxide particles as the main component of the antibacterial agent. On the one hand, the active center of the titanium dioxide particles can absorb the energy of the environment, inhibit or kill bacteria, thereby producing antibacterial properties. On the other hand, titanium dioxide, as a sunscreen, can effectively absorb ultraviolet rays Light and reduce the aging reaction of ultraviolet light on the surface of the material, thereby effectively improving the antibacterial and durable performance of the fabric.

Description

technical field [0001] The application relates to the field of textile materials, more specifically, it relates to an antibacterial fabric for sofa cushions and a production process thereof. Background technique [0002] The material of the sofa cushion is mainly cotton cloth or plant fiber, and the inner layer of the sofa cushion is made of plush or sponge filling, in order to increase the comfort of the sofa. The material of pure cotton cloth is thinner than that of short plush, and rich patterns can be printed on it through printing and dyeing process, so pure cotton quilted sofa cushion has a wide range of uses and a large audience. [0003] In the actual use process, because the sofa cushion of cotton fabric has good hygroscopicity and large specific surface area, it is easy to breed bacteria and harmful microorganisms, thereby threatening human health and affecting normal human activities. Therefore, silver-based antibacterial agents are often loaded on cotton fabrics....
