چکیده
|
The main topic investigated in this paper is the analysis of the effect of different spandex percentages on physical and mechanical properties of the denim fabric. the results showed that percentage of elastane has a significant effect on the physical and mechanical properties of cotton/ elastane woven denim fabric. the influence of various elastane percentages via the above denim fabric performance parameters is investigated by employing a one-way analysis of variance (anova) statistical software package. tensile strength of denim fabric decreases as the percentage of the elastane increases because of the lower tenacity of spandex fibers compared to cotton fibers. fabric breaking elongation increases as spandex percentage increases. the tear strength of denim fabric decreases as elastane percentage increases. as spandex percentage increased, the fabric contraction of the woven fabric increased, which made the fabric more compact and bulk, resulting in higher fabric thickness, fabric weight, and deep shade color. in addition, fabric stretchability and fabric elastic recovery increase with spandex percentage since elastane has higher stretch and makes the structure more compact, but fabric growth decreases as spandex percentage increases, due to the rather high recovery properties of spandex. the obtained results showed that lycra proportion inside fabric has an effect on the fabric tensile strength, breaking extension, tear strength, stretchability, fabric thickness, gsm, and fabric shade color.
