This study aims to show that the manner of fabric deformation during relaxation depends upon the twill angle line and its direction (twill S or Z). The quantity of the skewness is related to the float length and the twill angle in reverse, with the warp tension when changed from cotton to lycra filling yarns.


The experimental analytical method.


The most significant goals presented from this investigation are cost savings, time of production and metaphorically; new demands on denim fabric patterns presented.


Moving away from just chasing cheap, more innovative and progressive for manufacturing and end users search for denim, this paper served to shift the market share map for denim manufacturers, which is looks on nearly the most common problem facing the denim industry; skewness.



The author wishes to express his sincere appreciation to Damietta University for funding this project and DNM Ltd, Egypt for their collaboration by making available their manufacturing site and stuff for carrying out this project.

Declaration of Competing Interest: The author declare that he has no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
