Title (EN) FALSE TWIST YARN COMPRISING DYEABLE POLYOLEFIN FIBERS
(FR) FIL À FAUSSE TORSION COMPRENANT DES FIBRES DE POLYOLÉFINE POUVANT ÊTRE COLORÉES
(JA) 可染性ポリオレフィン繊維からなる仮撚加工糸
Abstract:
(EN) This false twist yarn comprises dyeable polyolefin fibers which are characterized as being polymer alloy fibers each having a sea-island structure in which a polyolefin (A) is the sea component and a polyester (B) having cyclohexanedicarboxylic acid compolymerized therein is the island component, and in which the dispersion diameter of the island component in a fiber cross-section is 30-1000 nm, wherein the number of the polymer alloy fibers is three or more, and the polymer alloy fibers have physical properties (1) and (2): (1) crimp recovery (CR) being 10-40%; and (2) hot-water dimensional change being 0.0-7.0%. As a result, a polyolefin false twist yarn capable of developing vivid and profound colors is provided even though the polyolefin fibers therein are light in weight.
(FR) La présente invention concerne un fil à fausse torsion comprenant des fibres de polyoléfine pouvant être colorées qui sont caractérisées en ce qu'elles sont des fibres d'alliage de polymère possédant chacune une structure mer-île dans laquelle une polyoléfine (A) est le composant mer et un polyester (B) comportant un acide cyclohexanedicarboxylique co-polymérisé est le composant île, où le diamètre de dispersion du composant île dans une section transversale de fibre est de 30 à 1 000 nm, le nombre de fibres d'alliage de polymère étant au moins trois, et les fibres d'alliage de polymère possédant les propriétés physiques (1) et (2) : (1) la récupération de frisure (CR) est comprise entre 10 et 40 % ; et (2) le changement dimensionnel dans l'eau chaude est compris entre 0,0 et 7,0 %. En conséquence, l'invention concerne un fil à fausse torsion de polyoléfine apte à développer des couleurs vives et profondes même avec des fibres de polyoléfine de poids léger.
(JA) ポリオレフィン(A)が海成分、シクロヘキサンジカルボン酸を共重合したポリエステル(B)が島成分である海島構造で、繊維横断面における島成分の分散径が30~1000nmであるポリマーアロイ繊維であって、該ポリマーアロイ繊維が3本以上からなり、下記(1)(2)の物性を有することを特徴とする可染性ポリオレフィン繊維からなる仮撚加工糸。 (1)伸縮復元率(CR) 10~40% (2)熱水寸法変化率 0.0~7.0% 軽量性に優れたポリオレフィン繊維でありながら鮮やかで深みのある発色性を有する可染性ポリオレフィン仮撚加工糸の提供。
