Document Type and Number:
Japanese Patent JPH04240255
Kind Code:
A
Abstract:
PURPOSE: To obtain a melt-blown nonwoven fabric having excellent needle- punching processability without using post-treatment such as application of lubricant.
CONSTITUTION: A fiber-forming polymer (e.g. polyamide) is compounded with 0.1-3.0wt.% of a diester-type surfactant (Emalox SA-2) derived from a ≥12C long-chain higher fatty acid and a polyhydric alcohol and the obtained mixture is subjected to melt-blowing to obtain the objective nonwoven fabric.
