Anti-mite fabric and processing method thereof

Abstract

The invention discloses an anti-mite fabric and a processing method thereof, the fabric adopts a three-layer composite structure of a skin-friendly layer, a functional core layer and a protective layer, the skin-friendly layer is a modal blended knitted fabric containing mint essential oil microcapsules, and the microcapsules are triggered by body temperature to release menthol to expel mites; the functional core layer is a chitin / titanium dioxide core-shell nanofiber membrane, 200-300 nanofibers form a 280-nanometer-aperture physical barrier, and chitin adsorption and titanium dioxide photocatalysis sterilization are combined; the protective layer is made of aminated regenerated cellulose woven cloth, and interlayer bonding and air permeability are enhanced. The production process comprises the steps of microcapsule preparation by a complex coacervation method, coaxial electrostatic spinning, plasma amination treatment and supercritical carbon dioxide crosslinking. The anti-mite repellent rate of the fabric is larger than or equal to 98%, the antibacterial rate is larger than or equal to 99%, the moisture permeability is larger than or equal to 8000 g / m / 24 h, the performance retention rate is higher than 94% after 50 times of washing, the problems of chemical residues, poor air permeability and insufficient durability of a traditional anti-mite fabric are solved, and the fabric has the advantages of being safe, comfortable and environmentally friendly.
