The Effect
of Twist Multiplier, Elastane Percentage and Pick Density on Denim Quality by A

For an end
consumer of denim garments, the most important factors are performance and
comfort after few aesthetic factors such as appearance and fashion appeal. For
stretchable denim fabric, the fit related comfort lies in ability of the fabric
to be stretched and recover when a repeated load is applied due to body
movements without any permanent set called bagging. In this study, the
interactive effect of twist multiplier of weft yarn, denier elastane fibre and
fabric areal density on performance of denim fabric was investigated. The
denier of elastane fibre used with weft yarn of three different twist
multiplier- 4.9, 5.2 and 5.5, is changed as 40D, 55D and 70D. The areal density
of fabric is changed through change in picks per inch as 50, 55 and 60.
Performance was analysed on the basis of results of breaking strength, breaking
elongation and cyclic loading stretch properties. The test results revealed
that the tensile strength and breaking elongation properties of denim fabric,
for both before and after cyclic loading are in the same trend, but after
cyclic loading due to fatigue behaviour, tensile strength and breaking
elongation was reduced. The breaking elongation increased as lycra content
increases in the fabric and with increase in lycra content percentage, tensile
strength was decreased slightly.
