Title (EN) LIQUID CRYSTALLINE TEXTILE MATERIAL AND TEXTILE PRODUCT
(FR) MATÉRIAU TEXTILE À CRISTAUX LIQUIDES ET PRODUIT TEXTILE
(JA) 液晶性繊維材料、及び繊維製品
Abstract:
(EN) The present invention provides a liquid crystalline textile material having thermal responsiveness at near normal temperature and yet having given or greater strength (durability), focusing on a phenomenon that when a liquid crystalline polyurethane makes phase transition between a crystal phase and an isotropic phase due to a temperature change, the elongation rate thereof changes. A liquid crystalline textile material 11 including a liquid crystalline polyurethane that reversibly stretches between a crystal phase and an isotropic phase in accordance with a temperature change, wherein the elongation rate in the fiber direction is set to 102-200%, with a state of the liquid crystalline polyurethane being most shrunk used as a point of reference (100%), and the shrinkage factor in the fiber direction is set to 98.04-50%, with a state of the liquid crystalline polyurethane being most expanded used as a point of reference (100%).
(FR) La présente invention concerne un matériau textile à cristaux liquides possédant une sensibilité thermique à une température proche de la normale, tout en possédant une résistance (durabilité) donnée ou supérieure, en se focalisant sur un phénomène selon lequel lorsqu'un polyuréthane à cristaux liquides effectue une transition de phase entre une phase cristalline et une phase isotrope en raison d'un changement de température, son taux d'allongement change. Un matériau textile à cristaux liquides (11) comprend un polyuréthane à cristaux liquides qui s'étire de manière réversible entre une phase cristalline et une phase isotrope en fonction d'un changement de température, le taux d'allongement dans la direction de la fibre étant fixé entre 102 et 200 %, un état du polyuréthane à cristaux liquides le plus rétracté étant utilisé comme point de référence (100 %), et le facteur de retrait dans la direction de la fibre étant fixé entre 98,04 et 50 %, un état du polyuréthane à cristaux liquides le plus expansé étant utilisé comme point de référence (100 %).
(JA) 温度変化によって液晶性ポリウレタンが液晶層及び等方相間を相転移するときに伸長率が変化する現象に着目し、常温付近で熱応答性を有しながら、一定以上の強度(耐久性)を有する液晶性繊維材料を提供する。 温度変化に応じて液晶相と等方相との間で可逆的に伸縮する液晶性ポリウレタンを含む液晶性繊維材料11であって、液晶性ポリウレタンが最も収縮している状態を基準(100%)として、繊維方向における伸長率が102~200%に設定され、又は液晶性ポリウレタンが最も伸長している状態を基準(100%)として、繊維方向における収縮率が98.04~50%に設定されている。
