Preparation method of composite functional fabric with antimicrobial, anti-ultraviolet, deodorization and self-cleaning functions

The invention discloses a preparation method of a composite functional fabric with antimicrobial, anti-ultraviolet, deodorization and self-cleaning functions. The preparation method comprises the steps of preparing an activated modified treatment liquid, preparing a nano-titania dispersion liquid, processing fabrics by virtue of the activated modified treatment liquid, processing the fabrics by virtue of the nano-titania dispersion liquid, and the like. After the composite functional fabric is processed, the UPF value is more than 100, the deodorization rate is more than 95%, the photocatalysis self-cleaning fading rate of the composite functional fabric to chili oil is 96.7%, and the antibacterial rate (to staphylococcus) is 98.6%; after the composite functional fabric is washed for ten times in families, the UPF value is more than 50, the deodorization rate of the composite functional fabric to substances (including ammonia gas, formaldehyde, acetaldehyde, sulfureted hydrogen, nicotine and trimethylamine) is more than 90%, the photocatalysis self-cleaning fading rate of the composite functional fabric to chili oil is 93.9%, and the antibacterial rate (to staphylococcus) is 95.8%.
