(FR) NON-TISSÉS À BASE DE POLYPROPYLÈNE SOUPLES
요약서: front page image
(EN)Disclosed herein is a nonwoven fabric comprising within the range of from 1 to 49 wt%, by weight of the fabric, of a reactor grade propylene-α-olefm copolymer possessing; within the range of from 5 to 35 wt%, by weight of the copolymer, of units derived from one or more of ethylene and/or C4 to C12 α-olefms; a melt flow rate (230°C/2.16kg) within the range of from 600 to 7500 g/10 min; and a weight average molecular weight of less than 200,000; and a second polypropylene having a melting point, Tm, of greater than HO0C and a melt flow rate (230°C/2.16kg) within the range of from 20 to 7500g/10 min; wherein the fabric has a Handle value of less than 60% (measuring the fabric of 35 g/m2 basis weight). The fabric can be used in structures comprising one or more layers of the fabric described herein, and can include any number of other fabric layers made from other materials.
(FR)La présente invention concerne un textile non-tissé comprenant dans la plage de 1 à 49 % en poids, en poids du textile, d’un copolymère propylène-a-oléfine de qualité pour réacteur possédant dans la plage de 5 à 35 % en poids, en poids du copolymère, de motifs dérivés d’un ou plusieurs de l’éthylène et/ou d'a-oléfines en C4 à C12; un indice de fluage (230 °C/2,16 kg) dans la plage de 600 à 7500 g/10 min; et un poids moléculaire moyen en poids de moins de 200 000; et un deuxième polypropylène ayant un point de fusion, Tm, de plus de 110 °C et un indice de fluage (230 °C/2,16 kg) dans la plage de 20 à 7500 g/10 min; le textile ayant un indice de toucher de moins de 60 % (en mesurant le textile de 35 g/m² de masse surfacique). Le textile peut être utilisé dans des structures comprenant une ou plusieurs couches du textile présentement décrit, et peut comprendre un nombre quelconque d’autres couches de textile fabriquées à partir d’autres matériaux.
