Influence of knitted fabric properties on edge sewing of knitted apparel

This paper discusses the influence of knitted fabric properties on the edge sewing process of the knitted apparel.The experiment chooses 10 kinds of knitted fabrics as samples and divides them into two groups based on the elongation at break and thickness by clustering methods.And then edge sewing or stitching experiments are performed with the sample fabrics using different sewing patterns,stitch densities,sewing threads and presser feet,and then test respectively the change of size,elongation,and strength of the sewn edges.The influential law of fabric properties on the sewn edge of the apparel and methods to improve the edge sewing quality of the knitted apparel are determined by statistical analysis of the experimental results with SPSS software and mean value comparison,T test and partial correlation analysis.The study shows that the better the extension properties of the fabric,the greater the influence on the size of the apparel sewn edge;the influence of the thickness of fabric on the elongation rate of the sewn edge is remarkable;the stitch density is proportional to the strength and elongation rate of the sewn edge;the size of the sewn edge is stable relatively when choosing teflon presser foot to sew them;and the elongation rate and breaking strength of the edge sewn with polyester thread are superior to those sewn with cotton thread.
