Influence of Low Temperature Plasma on Chitosan/ Waterborne Polyurethane Finishing on Cotton Fabric

Abstract:

Waterborne polyurethane and chitosan were mixed in different volume ratio, and finished on the cotton of plasma pre-treatment and non-plasma pre-treatment to discuss the influence of plasma pretreatment on the properties of the fabric. Firstly, the mixed aqueous emulsion was made into film and analyzed by FTIR. Secondly, the relationship between the properties of whiteness, wrinkle recovery performance and water vapor permeability of the fabric that finished by the only blended solution and the mixed ratio was studied. Finally, the property changes between the pretreatment with and without plasma was compared. The results showed that, the blended film not only had both polyurethane and chitosan characteristic peaks, but also generated the new characteristic peaks; the three properties of the fabric that finished by the only blended solution changed with the mixed ratio; the plasma pre-treatment would increase the fabric’s whiteness, decrease wrinkle recovery performance, but the water vapor permeability would improve obviously.
