In order to improve the sewing damage of cotton knitted fabrics in the sewing process,sewing enhancer with smoothing effect is often used.The alkali resistance,salt resistance and high temperature stability of sewing enhancer OE01 are analyzed,the change of fabric surface morphology before and after finishing is analyzed,and the effect of auxiliary dosage on sewing damage,color,fuzzing,pilling,bursting strength,softness and hydrophilicity of the fabrics is analyzed.The results show that the sewing enhancer OE01 has good alkali resistance,salt resistance,and high temperature stability,which can significantly improve the sewing damage and handle of the fabrics,but has only a slight effect on the color,anti-pilling,bursting strength and hydrophilicity.
