Problems solved by technology

However, the antibacterial products purchased by some consumers have problems such as skin itching and allergies during use, leaving potential safety hazards
Therefore, the safety of existing antibacterial textiles needs to be further improved
At the same time, although the antibacterial properties of existing antibacterial products are considerable, the persistence of the antibacterial effect is not enough, mainly because the antibacterial finishing agent itself has a weak combination with textiles and does not have good washing resistance. Safe and healthy textiles will become the main direction of future development

Abstract

The invention provides a preparation method of a microcapsule antibacterial functional finishing agent. According to the microcapsule antibacterial functional finishing agent, mesoporous silica coatedwith polyurethane serves as a wall material, aloin, lemon essential oil, vanilla oil and Chinese mugwort oil serve as core materials, and the weight ratio of the wall material to the core materials is 1:(1-5). A fabric finished by the finishing agent has good antibacterial effect, a combination action of the finishing agent and the fabric is high, and the antibacterial effect is more durable through sustained-release effect of a microcapsule. Antibacterial components used by the finishing agent are provided with natural extracts, safe and free from toxicity, and good health states of skins can be kept. The finishing agent has important application values in the field of textile.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of a microcapsule antibacterial functional finishing agent. Background technique [0002] In recent years, more and more attention has been paid to the functionality of clothing, especially for various intimate clothing and baby clothing, and antibacterial clothing, antibacterial textiles and other products are increasing day by day. However, the antibacterial products purchased by some consumers have problems such as skin itching and allergies during use, leaving potential safety hazards. Therefore, the safety of existing antibacterial textiles needs to be further improved. At the same time, although the antibacterial properties of existing antibacterial products are considerable, the persistence of the antibacterial effect is not enough, mainly because the antibacterial finishing agent itself has a weak combination with textiles and does not h...
