NONWOVEN AND STRETCHABLE LAMINATE

摘要

Nonwovens that have excellent stretchability in both the machine direction and the cross direction, and laminates including such nonwovens. The nonwoven includes fibers having a core-in-sheath structure including a core part and sheath part. The core part includes a thermoplastic elastomer. The sheath part includes a polyolefin having a melt flow rate greater than or equal to 100 g/10 minutes, and a viscosity lower than the thermoplastic elastomer at a specific temperature selected in a temperature range of from 220° C. to 260° C.

1. A nonwoven comprising fibers having a core-in-sheath structure comprising a core part and a sheath part;
the core part comprising a thermoplastic elastomer; and the sheath part comprising a polyolefin of a lower viscosity than the thermoplastic elastomer at a specific temperature selected in a temperature range of greater than or equal to 220° C. to less than or equal to 260° C., and a melt flow rate of the polyolefin being greater than or equal to 100 g/10 minutes.
