Abstract
Denim is a fabric manufactured out of 100% cotton fibers and the woven fabric construction is in general of twill weave construction. The wearers, especially the youth, in cities beyond the metros and mini metros are growing exceptionally inspirational that they are increasingly accepting denim as a core apparel category of fabric among the other varieties to be worn as an everyday casual garment. Traditionally, the denim fabric is blue denim constructed with a warp-faced twill in a 3 up 1 down construction. In general, coarse yarns spun from ring spinning system or in rotor spinning system are used for the denim fabric manufacture. The warp yarns are dyed with a solid colour like indigo dyes and the weft yarns are used without dyed. It means that there are more warp yarns than weft yarns appear on the face of the fabric and this gives a characteristic of the denim fabric a bluer face on the face of the fabric and moreover, much paler and almost white background on the back side of the fabric. The count of the yarns used for the manufacture of denim fabrics is in the range of Ne 10, Ne12, Ne 16 & Ne 20. Further more the warp and weft counts are different in character. i.e. Ne 12 warp yarn and Ne 10 weft yarn. In this study, few denim fabric samples were tested for their fabric properties like air permeability, fabric weight in gsm, EPI, PPI, count of warp & weft, crease recovery angles, water vapour permeability and thermal properties.
