STRETCHABLE NONWOVEN FABRIC, METHOD FOR PRODUCING THE SAME AND PRESSURE-SENSITIVE ADHESIVE SHEET USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a stretchable nonwoven fabric having an excellent water repellency by a method using a nonhalogen type organic compound having low environmental load without using a fluorine-based or silicone-based post processing agent having high environmental load. SOLUTION: The stretchable nonwoven fabric comprises thermoplastic polyurethane filaments containing 0.1-1.0 wt.% of a higher fatty acid bisamide compound having≥100°C melting point in which the filaments are mutually self-bonded and has a water repellency not less than grade 3 measured by a spray testing method defined by JIS L 1092.
