Abstract:In this article, a novel method for evaluating the pinpoint effect of pile yarns of carpet is introduced. The method was initially accomplished by presenting a standard method for bundle preparation. Afterward the changes in free spaces between yarns in bundle cross section introduced as an index for evaluation of the degree of pinpoint effect of heat-set yarns on carpet appearance. To achieve the objectives of this research, yarns of different twist were heat set at various times and temperatures. The ratio o… Show more
