INFLUENCE OF YARN TYPES ON SINGLE-JERSEY KNITTED FABRIC PERFORMANCE

Abstract

Poliester and cotton fibres are the most utilized fibres by the textile and clothing sector, where ring spinning and open-end rotor spinning systems are the most widely used technologies to manufacture yarn by the sector. Also, with the increment in sustainable awareness in the sector, new approaches like use of recycled raw materials have been improved. The yarns converted from recycled fibres have been started to be intensively used in apparel and household textiles. However, recycled yarns are considered as mechanically weak. In the present study, it is aimed to how yarn type and fabric tightness affect the pilling tendency, mechanical characteristic, and vertical liquid transfer behaviour of knitted fabrics. For this purpose, six different knitted fabrics with different loop lengths were manufactured in single jersey construction using different yarn types. The selected yarns are 100% poliester (PES) ring carded, 100% cotton (Co) ring carded, and recycled polyester/cotton open-end rotor yarns in 35/65 proportion. In this direction, pilling resistance, bursting strength, and wicking tests were performed. It was observed that the knitted fabrics using PES ring carded yarns have medium to light pilling tendency, while the knitted fabrics using PES/Co blended open-end yarns show serious to medium pilling tendency. In addition, loose fabrics with higher loop length have no pilling tendency. Tight fabrics have the highest strength, whereas the fabrics from recycled open-end rotor yarns have poor strength. In both wale and course direction, the fabrics knitted using PES ring carded yarns displayed better wicking behaviour.
