Title (EN) FUSIBLE BICOMPONENT SPANDEX
(FR) ÉLASTHANNE À DEUX COMPOSANTS FUSIBLES
Abstract: front page image
(EN)Included are segmented polyurethane elastic fibers or spandex fibers, capable of bonding to polymer fiber such as nylon or polyamide fibers, in addition to bonding to itself, for apparel textile applications. More particularly the invention relates to bicomponent spandex fibers, with a heat resistant core and a heat sensitive sheath, spun from polymer solutions. The nylon fabrics containing such spandex fibers have enhanced stretch performance and improved surface appearance after heat treatment to activate the fusing and bonding between nylon fibers and spandex fibers.
(FR)L'invention concerne des fibres élastiques ou des fibres d'élasthanne en polyuréthane segmenté, capables d'être liées à une fibre polymère telle que des fibres de nylon ou polyamide, en plus d'être liées à elles-même, pour des applications de textile d'habillement. Plus particulièrement, l'invention concerne des fibres d'élasthanne à deux composants, ayant un noyau thermorésistant et une gaine thermosensible, tissées à partir de solutions polymères. Les tissus de nylon contenant de telles fibres d'élasthanne ont une performance d'étirement améliorée et un aspect de surface amélioré après un traitement thermique, pour activer la fusion et la liaison entre les fibres de nylon et les fibres d'élasthanne.
