Investigation of some surface roughness properties of woven fabrics produced with sustainable yarns

Abstract

Biodegradable polymers have attracted attention in recent years owing to increased sensibility to waste management. Polylactic acid (PLA) fibers have been recently utilized in textile products owing to its being biodegradable with low environmental impact. PLA fibers decompose into simpler compounds, thereby minimizing their environmental impact. Woven fabrics produced from sustainable yarns such as PLA or its blends may be good alternative textile products with a sustainable manner. This research was carried out to compare the surface roughness characteristics of some woven fabrics which are plain, 2/2 twill, and 5/1 satin woven samples. Fabric samples were woven with different weft yarns (polyester, polylactic acid, and recycled polyester/Trevira) at various weft yarn densities but with the same warp yarn properties. Surface roughness values of the samples including arithmetic average height (Ra), mean height of peaks (Rpm), mean depth of valleys (Rvm) and mean slope of the profile (Da) were analysed. Effect of different raw materials and fabric properties such as warp/weft density, weave pattern on surface roughness were tried to be analysed within the study.
