Problems solved by technology

CN101418517A takes quaternary ammonium salt and TEOS as raw materials, the antibacterial sol that obtains under the action of catalyst, but antibacterial agent is only adsorbed in the gel network by physical action, after 10 washings, the bacteriostatic rate to Escherichia coli and Staphylococcus aureus is equal Less than 80%, the washing effect is not ideal
Although the microcapsules formed by such natural wall materials have good biocompatibility, their mechanical properties and thermal stability are poor

Abstract

The invention discloses a skincare antibacterial microcapsule finishing agent and a preparation method and application thereof. The finishing agent comprises organosilicon microcapsule, the surface ofthe organosilicon microcapsule is modified by adopting organosilicon quaternary ammonium salt, and the organosilicon microcapsule takes aloe extract and squalene as core materials and tetraethyl orthosilicate. The preparation method includes: preparing the organosilicon microcapsule through a sol-gel method, and using organosilicon quaternary ammonium salt to modify the organosilicon microcapsuleto obtain the non-bonding skincare antibacterial microcapsule finishing agent. The finishing agent is ready for application by only directly adding into cellulose fiber fabric after-finishing liquid,adding of a binder is not needed, fabric after being finished has lasting skincare and moisturizing efficacy and lasting antibacterial performance, and hand feel style of the fabric is unaffected.

Description

technical field [0001] The invention belongs to the technical field of fabric finishing, and in particular relates to a skin care antibacterial microcapsule finishing agent and its preparation method and application. Background technique [0002] Personal textiles are a good carrier for skin care and health care. Various skin care and health care products are loaded onto underwear and fabrics through spinning, coating, finishing and other methods to play a sustainable role. The emergence of various health care functional textiles has increased the value of textiles. CN101418517A takes quaternary ammonium salt and TEOS as raw materials, the antibacterial sol that obtains under the action of catalyst, but antibacterial agent is only adsorbed in the gel network by physical action, after 10 washings, the bacteriostatic rate to Escherichia coli and Staphylococcus aureus is equal If it is less than 80%, the washing resistance effect is not ideal. CN102704280A discloses a VE micr...
