Abstract

Washing fastness is one of the most desired factors to aesthetic value of cloth. Color of garments can be deformed and changed due to various reasons. This kind of fading or change in the depth of shade leads the users very unsatisfied. Due to this, to study the reason of low washing fastness or color fading is very important. In the present work the effect of sunlight on color fastness to washing rate of different fabrics was studied. Seven different woven and knitted fabrics; 100% cotton, 100% polyester, polyestercotton, polyester-viscose and polyester-wool blended fabrics were used for this study. Each of the fabric was divided into two groups and colorfastness to washing was done before and after sunlight exposure. In case of fabric exposed to direct sunlight for different set of times, each fabric was tested for washing fastness. The half of those fabrics was directly tested for wash fastness without exposing to direct Sunlight. Both groups of tests were done as per ES ISO 105-C10:2016 standard. This investigation has shown that except polyester-viscose and polyester fabrics, all other samples wash fastness dropped significantly in terms of ratting digital grade as the exposure time has increased.
