Study on serviceability of nano-TiO_2 antibacterial cotton fabric

An investigation on the serviceability of the nano-TiO2 antibacterial finished cotton fabrics measured the compression,bending,shearing,extension and other low stress mechanical properties under low load of the cotton fabrics before and after nano-TiO2antibacterial finish using FAST system.The structural parameter and dimensional stability were also tested.The results showed that surface density,weft density,surface thickness,bending,formability,and shearing and relaxation shrinkage in weft direction of the finished fabrics increased slightly,while their shearing at warp 45°,relaxation shrinkage in warp direction and hygral expansion decreased.As a whole,most of their mechanical properties are still within the normal range and some is even better,so their serviceability also remains stable.
