INVESTIGATION OF THE USAGE OF ALTERNATIVE NEW GENERATION ECO-FRIENDLY FIBER BLENDS IN SYNTHETIC BASED DENIM FABRICS

Abstract

Polyester yarn is made from post-consumer waste such as bottles, fabrics, etc., in the composition of polyester ethylene terephthalate (PET). Polyester (mainly polyethylene terephthalate, PET) is the most commonly employed textile fibre with over 50% share in total production of textile fibres. Pla is a biobased and biodegradable polymer produced from renewable resources. PLA is also a thermoplastic aliphatic compostable polyester. In this study, 75% Cotton - 25% PLA, 75% Lyocell - 25% PLA and 75% Cotton - 25% PET blended yarns were produced as rigid, corespun and dualcore in the ring spinning system .The fabrics were weaved with produced yarn. In the finishing processes, some of the fabrics were treated with caustic and some of the fabrics were only washed. Fabrics containing PLA and PET were compared with each other. Fabrics containing PLA and PET fiber were evaluated in terms of strength, elasticity, abrasion and pilling performances. Although the weft tensile and tear properties of Cotton-PLA blended fabrics are lower than Lyocell-PLA and Cotton-PET blends, it has been indicated that PLA blended yarns can be used as an alternative to PET based yarns and fabrics.
