Effect of Elastane Parameters on the Dimensional and Mechanical Properties of Stretchable Denim Fabrics

Abstract

Denim is one of the most popular casual apparel all over the globe due to a variety of available looks, comfort, and convenience. Comfort and performance properties of stretched denim fabrics depend on the elastane content, which can be controlled through the linear density of elastane and draft-ratio in the core of the cotton yarn. Optimization of both of linear density and draft-ratio of elastane for the better performance of denim fabric were focused upon in this study. The results indicated that the elastane content inside the core of yarn affects the dimensional and mechanical properties of denim fabrics. Regression analysis indicated that elastane linear-density and draft-ratio had an almost equal significance on contraction after washing, stretchability, stiffness, skewness, and bow of fabric. However, the elastic properties of fabric were mainly dependent on the elastane draft-ratio. This study will be an endeavor for industry personnel to achieve more durable and dimensionally stable denim fabrics.

Effect of core material draft ratio and denier on core spun yarn and denim fabric properties pre and post washing

“…As only the weft yarn contained spandex, the result focused on the weft direction in both tensile and tear strength. The data showed higher tensile and tear strength for both 16 + 40D and 16 + 70D CSY in the case of low spandex draft which was also reported in M. B. Qadir et al [ 15 ] studies.…”

“…So, stretch denim fabrics are produced from spandex blended yarn for special applications [ 14 ]. The weft yarn of denim fabric can be replaced with CSY, where cotton is used as the sheath and spandex is used as the core to improve the comfort and performance of denim [ 15 ]. The wearer feels pleasant because the sheath material cotton gives the required aesthetic performance and the core spandex enhances the stretchability and elastic properties [ 16 ].…”

Preliminary Studies on Conversion of Sugarcane Bagasse into Sustainable Fibers for Apparel Textiles

“…Moisture management in fibers plays a vital role in enhancing the comfort properties of the fibers and their subsequent yarns and fabrics [21,22]. Natural fibers usually have a round shape and plenty of void spaces between the packed fiber bundles, which act as pockets for moisture retention, resulting in higher moisture content [23].…”
