Abstract

The invention discloses a water-washing-resistant natural antibacterial deodorant and a preparation method thereof. The antibacterial deodorant comprises the following ingredients: a cortex phellodendri extract, a Linearstripe Rabdosia extract, an origanum vulgare extract, carboxymethyl chitosan, ZnO-SiO2 composite nanoparticles, seaweed gel, octadecyl dimethyl betaine, aqueous polysiloxane and a thickener. The antibacterial deodorant plays a role in inhibiting a variety of bacteria and has a relatively high antibacterial and deodorizing function. The treatment agent can have a relatively high bonding force with fibers, and good antibacterial performance can still be kept after repeated water washing and long-time wearing friction.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a washable natural antibacterial deodorant and a preparation method thereof. Background technique [0002] Porous textiles can easily absorb sweat, cortex, and metabolic products secreted by the human body, thereby providing nutrients for microorganisms and helping the growth and reproduction of microorganisms. Especially under humid, nutritious and suitable temperature conditions, microorganisms multiply rapidly, and will generate plaques in the fabrics, causing mildew and embrittlement of the fabrics, which will have adverse effects on the human body during wearing or application. In addition, bacteria can also produce bad smell by decomposing human secretions, and lead to the transmission of skin diseases. By antibacterial and deodorizing finishing of fabrics, endowing fabrics with good antibacterial functions, inhibiting the spread and growth of harmful microorganisms, and...
