FLEXIBLE NONWOVEN FABRIC LAMINATE

摘要

A soft nonwoven fabric laminate having a spunbonded nonwoven fabric layer and a meltblown nonwoven fabric layer, with the spunbonded nonwoven fabric comprising a conjugate fiber made up of a propylene-based polymer (a) and an ethylene-based polymer (b) and the meltblown nonwoven fabric comprising a composition made up of a polyolefin-based elastomer (c) and a propylene-based polymer (d). The conjugate fiber is preferably a concentric or eccentric core-sheath-type or side-by-side-type conjugate fiber at least whose surface is made up of the component (b). Because of this, a nonwoven fabric laminate can be obtained that has satisfactory uniformity and excellent softness, gas permeability, water impermeability and interlaminar bonding strength. It is used suitably for raw materials for sanitary goods such as disposable diapers and packaging materials.
