Basic Comparison of the Properties of the Loop and Frotte Yarns, Woven and Knitted Fabrics
(Wydawnictwo Politechniki Łódzkiej. Wydział Technologii Materiałowych i Wzornictwa Tekstyliów, 2014) Grabowska, Katarzyna Ewa; Ciesielska-Wróbel, Izabela
Both loop fancy yarns and frotte fancy yarns belong to the group of yarns with continuous effects. The difference between frotte and loop yarn relies on the fact that the loop yarn is constructed with two core yarns and the frotte yarn is constructed with only one core yarn. The differences are evident in the shape of these two types of fancy yarns. These shape differences are the functions of the tensions of component yarns during the twisting process. The shape and construction of the fancy yarn influence its properties. The properties of loop and frotte fancy yarns, woven and knitted fabrics are compared in this article in order to find out the optimal yarn’s and fabric’s production condition to satisfy the final user and maintain low production costs. In terms of economy aspects only, the frotte fancy yarns are believed to be cheaper in production due to lower quantity of components utilize for their production to compare with loop fancy yarns, under conditions of the same settings of ring twisting frame.
