Abstract
In recent decades, consumer expectations and behavior have altered, focusing on more comfortable, well-fitting clothes. Wearing a slim-fitting garment helps to move more freely. Different elastomeric polymers are being introduced as a core constituent of the yarn to make denim fabric more comfortable during movement. The use of elastic material ensures that the material is stretchable and recoverable. The performance of several elastomeric hybrid yarns has been investigated in the first section of this study. Here, polyethylene terephthalate/polytrimethylene terephthalate (PET/PTT (T400®)), polytrimethylene terephthalate (PTT (Solotex®)), polybutylene terephthalate (PBT), and Lycra® (elastane) were used as the core component of the core and dual core-spun yarns. After that, 3/1 Z twill denim fabrics were made with these as weft yarns, and the fabric’s performance was assessed. It is found that dual core-spun yarns were shown to have lower strength than core-spun yarns, while it had a higher elongation value. PTT/PBT dual core-spun yarn had less unevenness and hairiness than yarn made solely of elastane. PBT in the core of the weft yarns provided strong strength, dimensional change, and stiffness qualities in the fabric. In contrast, elastane in the core of the weft yarns provided good elastic performance. Yarn and fabric performance for the hybrid yarns were statistically significant at a significance level of 0.05.
Highlights
Denim fabric is well accepted from the beginning, and still, it has its appeal due to its more variation and fashionable look
This study aims to do a comparative analysis among the 100% cotton, cotton covered core, and dual core-spun yarn properties and their fabric properties
It was observed that dual core-spun yarns have less strength than core-spun yarns in general and that having elastane in the core increases the elongation value of the yarns
Summary
Denim fabric is well accepted from the beginning, and still, it has its appeal due to its more variation and fashionable look. Its fashionable look and technological improvements in many aspects make denim a fashion icon to consumers.[1] As a widely accepted fabric, denim can be linked with the French fabric named serge de Nimes, indicated twill from Nimes,[1,2] and from an early age, denim is mostly made from cotton. Denim is produced from special types of fibers blended with cotton such as Lyocell, wool, flax, hemp, polyester, etc., as cotton raises sustainable issues in its cultivation time.[2,3]. People expect an elegant appearance and comfort, and technological advancements have fulfilled this demand.
