Research and application of the fabric shrinkage mechanism and its mathematical model

Having analyzed the relationships between shrinkage,weaving technique,parameters and material properties of woven fabrics,researchers set up a shrinkage model of the plain fabric,and proposed a math formula for calculating the shrinkage based on weaving technique and parameters of fabrics.Shrinkage experiments of cotton and viscose fabrics were performed.The results were compared with those of theoretical computations,and it has proven that the theoretical method is reliable.This formula was used to analyze the effects of yarn diameter,weft density,warp crimp ratio and swellability on warp shrinkage of the fabric.
