The effect of recycled fibers on the washing performance of denim fabrics

Abstract

In this study, denim fabrics were produced with yarns obtained from cotton fibers (CO), recycled cotton fibers obtained from yarn wastes (r-CO), and fibers produced from recycled PET bottles (r-PET). Enzyme and stone washing processes were applied systematically on these fabrics. Mass per unit area, breaking force, elongation at max force, tear strength, air permeability, and circular bending rigidity of fabrics were measured. The findings showed that r-CO fiber has negative effect on tear and breaking force. Breaking force, elongation at max force, and tear strength values of the fabrics increased depending on the increase in r-PET content. However, fabric handle was negatively affected associated with the r-PET ratio due to the increase in stiffness. Mass per unit area, breaking force, air permeability, and circular bending rigidity values of fabrics decreased after the washing processes. The effect of fibers on enzyme-or stone-washed fabrics showed a change according to finished fabrics. It can be said that fabrics containing r-PET are more resistant than cotton and recycled cotton in various aggressive denim washing methods such as bleaching or different washing process conditions such as rising temperature, and time.

Effect of Super White Washing Process Temperature and Optical Brightening Agent Concentration on Various Properties of Stretch Denim Fabric

“…Denim products have been widely recognized to significantly influence consumers' way of entity since they were invented [9,10]. Denim also has changed its appearance from traditional work-wear to casual clothing to the first wear and functional consumption [11,12]. In reality, Denim is a stiff and gloomy blue element without even any mode of attraction but washing is the groundbreaking mechanism that has transformed the global denim illustration [13][14][15].…”

PET Bottle Recycling for Sustainable Textiles

“…[19]. Most of the recycled PET flakes produced worldwide are utilized for staple fiber applications in textile sector ( Figure 2) [8,20,21].…”

“…It was found that knitted fabrics including virgin PET had better performance specifications than that of r-PET. According to the test results, they offered to use blends of r-PET fibers in suitable proportions according to usage area in order to prevent the decrease in fabric performance instead of using virgin PET fiber [19].…”
