Document Type and Number:
WIPO Patent Application WO/2019/167852
Kind Code:
A1
Abstract:
The present invention provides a non-woven fabric that: comprises a fiber comprising a polyolefin-based resin; and has water resistance, flexibility, and excellent workability. This laminated non-woven fabric has laminated therein: a spun-bond non-woven fabric comprising a fiber comprising a polyolefin-based resin (A); and a melt-blow non-woven fabric comprising a fiber comprising a polyolefin-based resin (B). The melt-flow rate of this laminated non-woven fabric is 80–850 g/10 mins. The surface roughness SMD, using the KES method, of at least one surface is 1.0–2.6 µm and the water pressure resistance per unit basis weight is at least 15 mm H2O/(g/m2).
