Abstract:

In this study the wrinkle force and recovery, elongation, strength, Poisson’s ratio and initial modulus of cotton/polyester blended fabric (65/35%) have been investigated. Different samples were considered after being treated by 1,2,3,4-butane tetra carboxylic acid (BTCA) and sodium hypophosphite (SHP) catalyst mixed with nano-titanium dioxide(TiO₂) as a co-catalyst by the pad-dry curing method. The wrinkle behaviour of the samples treated was assessed by a wrinkle force tester in addition to an Italian Mesdan tensile teste, and wrinkle recovery tester AATCC128, meanwhile their surfaces were evaluated by scanning electron microscopy (SEM). The results show that utilising the treatment substances led to wrinkle recovery improvement; in addition, the wrinkle force, Poisson’s ratio and initial modulus were also increased. On the other hand, it is observed that tensile properties in both directions (weft and warp) of the woven fabrics were decreased. Furthermore, a different observation was induced for each direction of the woven fabrics through considering the orthotropic feature, wrinkle force and recovery.
