Title (EN) POLYESTER COMPOSITE FIBER WITH EXCELLENT HEAT-SHIELDING PROPERTY AND COLORATION
(FR) FIBRE COMPOSITE POLYESTER DOTÉE D'UNE EXCELLENTE PROPRIÉTÉ DE PROTECTION CONTRE LA CHALEUR ET D'UNE EXCELLENTE COLORATION
(JA) 遮熱性及び発色性に優れたポリエステル系複合繊維
Abstract:
(EN) Provided is a polyester composite fiber which has a high reflectance at the wavelengths of infrared rays (e.g., 800-3,000 nm) that are readily converted to heat energy and which has coloration comparable to that of conventional polyester fibers. The polyester composite fiber is a core/sheath type composite fiber in which the core component is a thermoplastic polymer that contains 8-70 wt% sunlight-shielding substance having an average particle diameter of 0.5 µm or smaller, the sheath component is a polyester polymer containing 0.5-10 wt% heat-shielding fine particles that have an average particle diameter of 0.1 µm or smaller, are smaller than the sunlight-shielding substance, and can maintain the coloration, and the mass ratio of the core component to the sheath component is 10:90 to 30:70.
(FR) L'invention concerne une fibre composite polyester présentant un facteur de réflexion élevé au niveau des longueurs d'onde de rayons infrarouge (par exemple, 800-3 000 nm) facilement converties en énergie calorifique et présentant une coloration comparable à celle des fibres polyester classiques. La fibre composite polyester est une fibre composite du type âme/gaine dans laquelle le composant de l'âme est un polymère thermoplastique contenant 8-70 % en masse de substance de protection solaire présentant un diamètre de particule moyen inférieur ou égal à 0,5 µm, le composant de la gaine est un polymère polyester contenant 0,5-10 % en masse de fines particules de protection contre la chaleur présentant un diamètre particule moyen inférieur ou égal à 0,1 µm, inférieures à la substance de protection solaire et pouvant maintenir la coloration, et le rapport de masse du composant de l'âme au composant de la gaine est 10:90 à 30:70.
(JA)  熱エネルギーに変換されやすい赤外線の波長(例えば800~3000nm)において高い反射率を有し、かつ従来のポリエステル繊維と同程度の発色性を有するポリエステル系複合繊維を提供する。前記ポリエステル系複合繊維は、芯成分が平均粒子径0.5μm以下の太陽光遮蔽物質を8重量%以上70重量%以下含有する熱可塑性重合体であり、鞘成分が平均粒子径0.1μm以下で、前記太陽光遮蔽物質よりも小さく、発色性を維持できる遮熱性微粒子を0.5重量%以上10重量%以下含有するポリエステル系重合体であり、かつ芯成分と鞘成分との質量比率が10:90~30:70である芯鞘型複合繊維である。
