Document Type and Number:
WIPO Patent Application WO/2022/181590
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a spunbond nonwoven fabric that has excellent flexibility and feel, uniform formation, strength sufficient to withstand practical use, and excellent productivity. The present invention is a spunbond nonwoven fabric comprising conjugated fibers having a polyethylene-based resin as a main component. The spunbond nonwoven fabric has a fused part and a non-fused part. A softening temperature Tss (℃) of a surface layer of the conjugated fibers in the non-fused part and a softening temperature Tsc (℃) of an internal layer of the conjugated fibers in the non-fused part satisfy the following formula (a). Formula (a): (Tss+5)≤Tsc≤(Tss+30)
