STUDY OF THE CREASE REACTION OF THE WORSTED FABRIC TYPES
Abstract
In this paper, it was analyzed the crease behavior of the assortments of fabrics made of worsted yarns type for manufacture of clothing. Crease recovery behaviour is an important property of fabrics for apparel applications. The creasing of woven materials made from combed yarns type wool used for ready-clothes is an undesired deformation effect with temporary or permanent character, which is caused by a composed strain of bending and compression during utilization, processing or maintenance. It is manifested by the appearance of wrinkles, folds or stripes on the surface of wovens materials, thus diminishing their qualitative appearance and also their practical value. By the experimental determinations were revealed the factors which influence the returning capacity from wrinkling/bending of fabric assortments (fibrous composition, component fiber properties, structure parameters of fabrics, mechanical properties of warp and weft yarns and fabric finishing treatments). The measurement is applied to standardized fabric samples and 180 ° bent, pressed in the direction of one of the component yarn systems with mass-dependent bending loads on the surface unit for a specified time. After removing the bending load, the specimen relaxes freely within a specified time interval, then the angle of return is measured. Creasing of a fabric during wear is not change in appearance that is generally desired. The ability of a fabric to resist creasing is in the first instance dependent on the type of fiber used in its construction.
