Effect of coating ratio and weft density on some physical properties of upholstery fabrics

Abstract

This paper aims to examine the effects of coating ratio (g/m(2)) and weft density (picks/cm) on some mechanical properties of coated fabrics such as abrasion, pilling, air permeability and seam slippage strength in warp and weft direction of fabrics. In this research, 100% Polyester upholstery fabrics were woven at three levels of weft density as 5, 7 and 9 picks/cm on Dornier weaving machine with the same warp density of 8 ends/cm. Three coating ratios were selected as 30 g/m(2), 60 g/m(2) and 90 g/m(2) for applying acrylic foam coating substance to the upholstery fabrics. 18 different coated fabrics were produced under controlled production processes where half of them were sent to an additional process of needle punching before coating and half of them were not. Plain type upholstery fabrics were evaluated in terms of abrasion, pilling grade, air permeability and seam slippage strength forces in warp and weft directions. According to test results, pilling results of upholstery fabrics which were exposed to only coating process were more satisfying comparing to coated needle punched fabric groups. According to two-way ANOVA test; coating ratio was a significant factor among the coated fabrics whereas coating ratio, weft density and their interaction were insignificant factors among the coated needle punched upholstery fabrics with respect to abrasion results in terms of fabrics' mass loss (%). Air permeability property, seam slippage strength in weft direction were significantly affected by the weft density, coating ratio and their interaction among the coated and coated needle punched fabric groups. Weft density was an insignificant factor for the seam slippage strength values in warp direction among the coated fabric groups at significance level of 0.05.
