Abstract:
For professionals working in the weaving
industries worldwide, accurate estimation of warp and
weft consumption is a crucial procedure. Both
underestimating and overestimating have negative
commercial and economic effects. The work presented
here is an effort to determine the crimp percentage of
denim fabric utilizing a variety of techniques, including
marking, set length, and standard crimp tester methods.
The investigation was place at a denim weaving facility
close to Dhaka, Bangladesh. In this regard, the crimp
percentage of denim fabrics with various structures was
examined. The set length approach appears to be the
most accurate one for calculating crimp%. The study
indicates that depending on the fabric construction 10%
to 13% crimp is imparted on warp at grey stage, but after
finishing it becomes as high as 27% to 30%. This is due
to the deliberate length wise shrinkage carried out in the
finishing section after weaving. The warp crimp was
found to be substantially lower than the warp crimp in
denim, as expected, but the completed crimp was
significantly greater than the grey crimp. We discovered
that warp had a lower crimp% than weft. It's because
weaving maintains tension on the warp yarns.
Additionally, they are better and stronger yarn than
weft. So they stop extending further. Weft yarns, on the
other hand, are maintained with low tension and poor
quality. in order to stretch farther. Their crimp
percentage is higher as a result.
