In the present study, the effects of structure and process parameters on the tactile properties of cotton-knitted fabrics had been investigated. The examined parameters were elastane plating, count of yarns and English gauge of knitting machine. The tactile quality was measured using sensory analysis and instrumental techniques. The obtained results showed that the variations of the production parameters induce a significant effect on 11 sensory attributes assessed by a French-trained panel. Compression and surface properties, measured by the Kawabata Evaluation System are affected too by these variations. Using principal component analysis, the correlation between instrumental data and sensory scores had highlighted compression resilience, geometrical and frictional roughness as significant parameters. The practical issue of the research presented in this article is to provide to textile and garment manufacturers the existed relationship between production parameters and the tactile properties of knitted fabrics. Although several studies on the tactile properties of woven fabrics were performed, a lack in the investigations intertwining tactile characteristics of knits from instrumental and sensory techniques has been noted. The correlation between the sensory attributes, assessed by a French-trained panel, and the compression and surface properties measured by the Kawabata Evaluation System is established.
