The effect of glycine treatment on the morphology and tensile properties of cotton yarn

Abstract

In this study, a detailed exploration of the effects of glycine treatment on the morphology and tensile properties of cotton yarn is presented. From the cross-sectional morphological studies, it can be noticed that glycine treatment at pH 11 swelled the cotton fibres. Linear density measurements showed that the yarn weight increased after glycine treatment irrespective of the pH. The increased linear density may be due to the weight gained by the yarn because of glycine treatment as well as shrinkage. The results of the tensile properties of cotton yarn treated with glycine showed that glycine treatment protected the samples from the significant drop in yarn tensile strength at acidic pH. The breaking strain was increased significantly in pH 11 glycine treated yarn by 70%. The glycine treatment at acidic condition has also changed the strain value, at pH 4, where the strain value increased by 38%.
