Boiling-water shrinkage of warp-knitted cotton-like polyester filament fabric and its influence factors

To understand the relationship between the weave structure and boiling-water shrinkage of warp-knitted polyester cotton-like fabric,its crimp percentage,boiling-water shrinkage,and overall shrinkage were tested based on the principle of cotton-like processing,and chief factors influencing the boiling-water shrinkage were obtained via the orthogonal experiment. The wale count is the main factor influencing the coursewise crimp percentage,boiling-water shrinkage and overall shrinkage,while the front guide bar extensibility length is the main factor influencing the walewise crimp percentage and boiling-water shrinkage. Although the increase of walewise density and change of weave structure have a certain influence on the boiling-water shrinkage on both directions,little influence is observed on the overall shrinkage.
