Description

Antibacterial mildew-proof textile and preparation method thereof Technical Field The invention relates to the technical field of textiles, in particular to an antibacterial and mildew-proof textile and a preparation method thereof. Background The textile can absorb sweat, sebum and other excretions secreted by human body, and under the environment with proper temperature and humidity, the microorganisms which are lodged on the textile can be greatly propagated to decompose the excretions of human body and produce substances with peculiar smell such as ammonia, or generate bacterial spots on the textile, so that the textile is uncomfortable or bad to human body in the wearing or application process, and is mildewed, embrittled and even degenerated. For example, publication No. CN105239380B discloses an antibacterial mildew-proof textile and a preparation method thereof, and the invention obtains a textile material with excellent antibacterial durability through ultrasonic impregnation at a certain temperature by the synergistic effect of dodecyl dimethyl betaine and nano ZnO modified dihydroxyl polydiphenylsiloxane, and the antibacterial activity of the textile material can be maintained to be more than 97 percent after 50 times of washing, and the good mechanical property is maintained.
