ELASTIC NONWOVEN FABRIC, PROCESS FOR PRODUCING THE SAME, AND TEXTILE PRODUCT COMPRISING THE ELASTIC NONWOVEN FABRIC

摘要

An elastic nonwoven fabric which is made of a crystalline resin composition comprising a lowly crystalline polypropylene and a highly crystalline polypropylene, characterized in that the lowly crystalline polypropylene satisfies the following (a) and (b) and the crystalline resin composition has a crystallization temperature (Tc) as measured with a differential scanning calorimeter (DSC) of 20-100°C. (a) When the lowly crystalline polypropylene is examined with a differential scanning calorimeter (DSC) by a method in which the polypropylene is held in a nitrogen atmosphere at-10°C for 5 minutes and then heated at 10 °C/min, it gives a melting endotherm curve in which the melting point (Tm-D) defined as the temperature corresponding to the top of the peak observed on the most high-temperature side is 0-120°C. (b) The lowly crystalline polypropylene has a stereoregularity index ([mm]) of 50-90 mol%.
