Determining the visual Impression of cotton fabrics while Rotating.

Abstract

In order to identify the light reflectance from cotton fabrics produced from various (spun yarn., ( carded – open end ) ,an attempted measured Light reflectance distribution (CIELAB L*) by using a (GCMS-4 Gonio)-( Spectrophotometric color measurement system) at various Illumination angle (θi) and Viewing angle(θv) with turning point(θw) from ( 0-90)o in both direction .Results clarify the relations between the distribution pattern (L*) with fabrics made from different spun yarn which had an effect for fabrics on visual sense of hymen and indicate more about aesthetics of cotton fabric while rotating. Therefore, the results indicate that L* reflectance measurement for cotton woven fabric shows that lightness values depended on method of spinning but in closer values, weave density also give parameter in light reflectance from woven fabric in weft direction , Illumination angle and Viewing angle also indicate an important parameter for visual sense from fabrics and its related to aesthetic properties. In shorts: (θw) was found to be the most accurate parameter for determining the change of lightness from shiny to dull in visual assessment for cotton woven fabrics.
