Properties of CNW/CS/SF self-assembled modified cotton fabric
Nano-fiber whiskers(CNW),chitosan(CS)and fibroin protein(SF)are used to self-assembly modification of cotton fabrics.The micro-morphology,molecular structure,wearability and UV protection properties of the modified cotton fabric are investigated in order to develop multifunctional wearable fabrics.The test shows that the surface of the modified fabric exhibits a porous morphology with a high porosity.In the process of CNW/CS/SF self-assembly,a new bond reaction occurs between different substances,which promotes the structural stability of the self-assembly layer,and improves the thermal,moisture recovery,mechanical and UV protection properties of the fabric.With the increasing of the number of self-assembled layers,the porosity decreases,and the thermal,moisture recovery,mechanical and UV protection properties increase.The comprehensive analysis shows that it is feasible to develop multifunctional wear fabric by using CNW/CS/SF self-assembly modified cotton fabric.
