EVALUATION OF SOME MECHANICAL PROPERTIES OF WARP-KNITTED FABRICS USING RECYCLED POLYESTER YARN

Abstract

To meet the trend of sustainable development, the textile industry has promoted the use of recycled materials in the production of garments. Recycled Polyester fiber (r-PET) is a sustainable manufacturing material that benefits the environment by reducing plastic waste and carbon emissions in textile production. This paper presents the results of a study evaluating several indicators such as tensile strength, elongation, dimensional change after washing, and water capillary action of three warp-knitted fabric samples with different weave patterns, course/wale densities, weights g/m² and thicknesses, but using the same type of 100% recycled Polyester 40D combined with Spandex 30D yarn, for use in sportswear. The research results provide a scientific basis for designing warp-knitted fabrics using recycled r-PET yarn, aiming to create fabrics suitable for sportswear products according to specific usage requirements.
