Abstract
The performance of a garment during its usage is very important for consumers. Performance as such is a very wide term and may range from satisfying the requirements during its use to the durability. Comfort is also considered by many consumers today as one of the performance requirements. For stretchable denim fabric, the fit related comfort lies in the ability of the material to be stretched when a load is applied according to body movements and retain to its original length. While designing the stretch denim, fabric weight and weave plays important role for comfort, performance and fashion. In this study, the effect of fabric parameters such as areal density, Lycra content and weave on characteristics of stretchable denim fabrics were investigated. Various properties such as thickness, tensile strength, flexural rigidity, stretch and recovery properties and air permeability of the fabrics were evaluated. The test results revealed that increasing the fabric weight increased fabric warp tensile strength, compressibility, stretch and recovery, whereas the flexural rigidity, weft tensile strength and air permeability were decreased. As Lycra contents in fabric increased, fabric thickness was increased which resulted in higher flexural rigidity of fabric. Fabric construction and weave also influenced the fabric flexural rigidity and air permeability related to performance and comfort of stretchable denim fabric.

Denim, the favourite fabric of the youngsters has come a long way
In addition with the increased Lycra content, the fabric thickness was increased as shown in Table 1, which resulted in the increase of the compressibility and compression recovery properties
From analysis of variance (ANOVA) analysis it was observed that there is a significant difference in fabric compressibility and compression recovery of the denim fabrics having different Lycra content (F=1290.92, p ≤ 0.001)
Summary
The consumer’s choice, unstable and unpredictable, it has remained almost the same while selecting denim for their fashion item [1,2,3,4]. Stretch denim usually incorporates an elastic component (such as elastane) into the fabric to allow a degree of stretchability in garments [6,7]. The traditional denim is rather hard and high density fabrics with high mass per unit area. Twill weaves such as three-up-one-down (3/1) and two-up-one-down (2/1) are predominantly used for denim construction [11,12,13]. Fashionable, affordable and durable for which it is popular in all the age groups
