Abstract: front page image
(EN)A needle-punched nonwoven fabric, which has a mixing ratio of a polylactic acid short fiber containing an epoxy compound of 20-40 mass%, a mixing ratio of a polyethylene terephthalate short fiber of 80-60 mass%, a basis weight of 100-200 g/m2, and tensile forces, at 20oC per unit basis weight, in the longitudinal direction of 0.30-0.60 (N/cm)/(g/m2) and in the transverse direction of 0.48-0.90(N/cm)/(g/m2). Thus, it is possible to provide a needle-punched nonwoven fabric which imposes a low environmental burden, shows a sufficient durability when used as an automobile interior material, and is easily stretchable in molding.
(FR)La présente invention concerne un tissu non tissé aiguilleté, qui possède un rapport de mélange d'une fibre courte d'acide polylactique qui contient un composé époxy de 20 à 40 % massique, un rapport de mélange d'une fibre courte de polyéthylène téréphtalate de 80 à 60 % massique, une masse surfacique de 100 à 200 g/m2, et des forces de traction, à 20 oC par masse surfacique unitaire, dans la direction longitudinale de 0,30 à 0,60 (N/cm)/(g/m2) et dans la direction transversale de 0,48 à 0,90(N/cm)/(g/m2). Ainsi, il est possible de fournir un tissu non tissé aiguilleté qui impose une faible charge écologique, présente une durabilité suffisante lorsqu'il est utilisé en tant que matériau intérieur pour automobile, et est facile à étirer durant le moulage.
(JA) 本発明は、エポキシ系化合物を含有するポリ乳酸短繊維の混率が20~40質量%、かつポリエチレンテレフタレート短繊維の混率が80~60質量%であり、目付が100~200g/mであり、20℃における単位目付当たりの引張強力が、縦方向0.30~0.60(N/cm)/(g/m)、かつ横方向0.48~0.90(N/cm)/(g/m)であるニードルパンチ不織布に関する。 本発明により、環境負荷が低く、自動車内装材として用いることができる耐久性を持ち、成型時に伸びやすいニードルパンチ不織布が提供される。
