An investigation of the effect of utilizing PLA weft yarn on some fabric properties

Abstract

Using Polylactic acid (PLA) fibers in textiles may be accepted as a sustainable manner in terms of their being biodegradable under specific conditions, unlike traditional synthetic fibers like polyester or nylon, which take a long time to break down and contribute to environmental pollution. Additionally, PLA fibers break down into simpler compounds, reducing environmental impact. This study investigates the effect of some weft yarn properties such as weft yarn types including PLA yarn, recycled PET-Trevira yarn, Polyester yarn, and the weft density factors on tear strength, air permeability, and some fastness properties of plain, twill, and satin fabrics. 9 different types of plain, twill, and satin fabric groups were produced by using 3 different weft yarn types (Polyester, recycled Polyester-Trevira, PLA) at the 3 different weft densities (24,26,28 threads/cm for plain, 32, 34,36 threads/ cm for twill, 36,38,40 threads/cm for satin groups) were produced where a total of 27 different drapery samples were obtained. SPSS Statistical analyses and bar graphs were used for the evaluation of the results. Randomized two-way ANOVA was used at the significance level of 0.05 among the plain, twill, and satin groups separately. Additionally, SNK tests were also performed to observe the means of each parameter. General evaluations of washing, dry cleaning, and rubbing fastness of dyed fabrics were also inserted.
