Abstract
Denim fabric is well accepted, and still, now it has appeal for its variation and technological improvement. Denim is mostly produced from cotton, which is concerned with the sustainability issue. In this article, a new generation of sustainable yarn has been developed from lyocell and cellulosic acetate fiber, blended with cotton fiber having the object to alternate and minimize the cotton fiber amount in the denim production. In this study, denim fabric was produced from Lyocell (Tencel®)/Cotton blended warp yarn and Cellulosic acetate (CA(Naia®))/Cotton blended dual core-spun weft yarn then fabric performances have been analyzed. From the analysis, 100% CO fabric weight changes more than other samples due to higher shrinkage than others. Regenerated yarn samples have lower growth percentages with high elasticity than 100% cotton. Regenerated blended yarn fabric samples have lower tear strength on the weft side than 100% CO sample, but they have more tear and tensile strength on the warp side. Denim fabric from sustainable yarns is also wear comfortable.
