Experimental determination of the effect of napping on mechanical properties of bi-elastic woven fabrics [Şardonlamanin bi˙-elasti˙k dokuma kumaşlarda mekani˙k özelli˙kler üzeri˙ne etki˙si˙ni˙n deneysel beli˙rlenmesi˙]

In this study,bi-elastic woven fabric with elastane in both weft and warp directions was used. napped fabric was obtained by applying napping process twice at 10m/min drum speed on to the fabric. the effect of napping on the mechanical properties of bi-elastic woven fabric was determined experimentally by analyzing tensile strength,elasticity,seam slippage and pilling properties of fabrics. one way analysis of variance (anova) results indicate that the napping process has significant effects on the mechanical properties of woven fabric. the mechanical force applied onto the fabric during the napping process has effected tensile strength and seam slippage strength negatively by disrupting the mechanical performance of the fabric. in addition,it has reduced the elasticity by damaging the elastane in the fabric and caused to increase the pilling tendency of the fabric.
