The removal and pretreatment effects of pectinase, cellulase, xylanase and laccase alone and mixed treatment on pectin and lignin in Chinese linen cotton fabric manufacturers were studied and compared with traditional techniques. The results show that although the strength loss of fabrics by Chinese linen fabric manufacturers is much lower than that of traditional pretreatment processes, the removal rate of lignin is still far from the traditional pretreatment process. The removal rate of the glue is also not as good as the conventional pretreatment process. In terms of pre-treatment effect, the wettability and hemp removal of Chinese linen cotton fabric manufacturers have a certain gap compared with the traditional pre-treatment process.
According to the impurity content of flax and cotton fiber, the pectinase, xylanase, cellulase and laccase were tested to determine the physical and mechanical properties, the wearing performance, the air permeability and the thermal insulation property of the treated fabric. The main indicators are compared with the traditional high-temperature, strong-alkali Chinese linen cotton fabric manufacturer's pre-treatment effect, and the Chinese linen cotton fabric manufacturer's Chinese linen cotton fabric manufacturer's pre-treatment steaming process is explored.
This topic is a preliminary study of the pretreatment of Chinese linen cotton fabric manufacturers. It analyzes the effect of traditional pretreatment on the removal of impurities on cotton fabrics and the wettability of cotton fabrics. The results show that alkali scouring can remove most of the non-cellulosic material on cotton fiber, but the wettability of cotton fabric is extremely poor. Bleaching alone removes most of the pectin on cotton fibers, but it can hardly remove cotton wax, and the wettability of cotton fabrics is also poor. Hydrogen peroxide bleaching after alkali scouring, although only a small amount of impurities on the cotton fiber is reduced, but can effectively improve the wettability of the cotton fabric.
