Anti-permeability and moisture absorption different-function knitted fabric and production process thereof

The invention discloses an anti-permeability and moisture absorption different-function knitted fabric and a production process thereof. The anti-permeability and moisture absorption different-function knitted fabric is of a double-layer structure, a middle connection tuck is connected between the outer layer and the inner layer, the outer layer and the middle connection tuck are made of water-repellency terylene subjected to surface modification processing, and the inner layer is made of terylene with irregular sections and having moisture absorption and sweat releasing functions. The production process of the anti-permeability and moisture absorption different-function knitted fabric includes steps of performing weaving to obtain grey fabric according to the double-layer textile design; performing preprocessing, dyeing, softening, dewatering and wet cutting for the grey fabric; and performing after finishing through a setting machine. According to the anti-permeability and moisture absorption different-function knitted fabric and the production process thereof, two different functions are combined in the inner layer and the outer layer of the fabric, and requirements of sports knitwear for combining inner layer moisture absorption and sweat releasing functions with outer layer sweat stain prevention function are met.
