Functionalizaton of Linen Fabric using Poly (N-vinyl-2-pyrrolidone)

TO IMPROVE the resiliency as well as to functionalize linen.... fabric to resist S. aureus and E. coli bacteria and block UV-B radiation, PVP was incorporated into easy care finishing formulations to chelate the TiO2 nano-particles and Cupper sulphate as a catalyst. Factors affecting the crosslinking process were studied. The obtained results indicate that: center dot the easy care finishing of linen fabric using DMDHEU, 50-75 g/l, as a crosslinker enhances the nitrogen content, resiliency and yellowness along with decreasing the tensile strength as well as the wettability of the treated fabrics, center dot incorporation of 4% PVP in the easy care finishing formulation of linen fabrics in presence of 50 g/l DMDHEU, enhances the nitrogen content, tensile strength and yellowness along with a decrease in the resiliency as well as the wettability of the treated fabrics, center dot esterification of linen fabrics with CA or BTCA in presence of 4% PVP is accompanied by an enhancement in the nitrogen content as well as tensile strength along with a decrease in the resiliency, wettability and yellowness of the treated fabrics, center dot incorporation of CuSO4 as a catalyst or TiO2 nano particles in the DMDHEU finishing baths in the presence of PVP enhances the extents of the antibacterial as well as the UV blocking properties of the treated fabrics, center dot the functionalized linen fabric samples are durable up to 10 washing cycles with little drops in their functionalities.
