Abstract: Abstract cotton-like PET warp fabric’s weaving shrinkage and boiled water shrinkage were researched and analysised in this paper. By using the chart analysis and unequal level orthogonal experimental method, it’s discussed that related laws and impact of important factor in woven fabric shrinkage and boiled water shrinkage overall of the cotton-like PET warp fabric’s shrinkage. Experimental results show that: the different organizational design for cotton-like PET warp fabric’s shrinkage have a certain regularity influence, pulling density is the most important factor to affect the fabric shrinkage.

Key words: cotton-like polyester filament, warp-knitted fabric, boiling-water shrinkage, weave structure
