Abstract
This study investigated the puckering of seams of cotton threads and polyester-spun ones in cotton fabrics. Machine washing were repeated twenty times under the conditions requested for home washing and three methods were used for finishing. After washing, the puckering ratio was calculated with a steel scale. The puckering ratio was compared for the seam of cotton threads with the seam of polyester-spun threads. The results show that the puckering ratio of the polyester-spun threads was smaller than the cotton ones.
