Comparative analysis of cotton covered elastomeric hybrid yarns and denim fabric properties

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.

Low-bagging (growth) stretch denim yarn production by spinning optimization of cotton-wrapped dual-core elastane and T400 multifilament

“…The literature review provides enormous outcomes on the improvement of the properties of core-spun yarns containing single-core filament, mostly elastane. Textile researchers and producers have very recently developed dual-core yarns, and due to being a new type, there is a special focus on these yarns [ 4 , 7 , 8 , [13] , [14] , [15] , [16] , [17] , [18] , [19] ]. However, less significant research on optimizing the spinning parameters of dual-core yarns highlights the need for further investigations.…”

Thermophysiological comfort and objective hand properties of modal, Naia™, cashmere and cotton included denim fabrics

“…This supports the previous study of fabrics including elastane, as single or double core yarns, having greater stiffness than fabrics that do not. 40 The lowest warp flexural rigidity was observed in T1 coded 50% modal/ 50% Naia™ included fabric, and the lowest weft flexural rigidity value was observed in T4 coded 36% Naia™/35% modal/25% cotton/4% cashmere included fabric. The overall flexural rigidity results of the fabrics are shown in Figure 8.…”

Employing Response Surface Methodology in the Production of Elastic Jute Yarn Suitable for Stretch-denim Applications

“…Normally, cotton staple bers have been a favorite choice for the sheath (Babaarslan et al, 2021;Erbil et al, 2022;Zou et al, 2023). The elastane core lament (such as Lycra®, Creora® and Inviya® I-300) provides elastic properties while the sheath cotton bers contribute aesthetic properties like absorbance, comfort and feel (Kiliç et al, 2020).…”
