Title:
FIBER MADE OF POLYPROPYLENE
Document Type and Number:
Japanese Patent JPH10195714
Kind Code:
A
Abstract:
To obtain a polypropylene excellent in mechanical strength and elongation.
This yarn made of a polypropylene is obtained by thermally molding a polypropylene having 0.05-50g/10 minutes melt flow rate measured at 230°C under 2.16kg load, the temperature at the maximum peak position of an endothermic curve measured by a differential scanning calorimeter in a range of 130-170°C and the mesopendant isotacticity measured by 13C-NMR in the range of 80-100%, the molecular weight distribution (Mw/Mn) measured by gel permeation chromatography in the range of 1.5-3.5 and ≤1.5wt.% decane- soluble component at a room temperature.
