FLEXIBLE LAMINATE OF NONWOVEN FABRICS

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-ethylene random copolymer (a) and an ethylene-based polymer (b) and the meltblown nonwoven fabric comprising a particular polymer containing ethylene units. The conjugate fiber is preferably a concentric or eccentric core-sheath type or side-by-side type conjugate fiber whose surface is made up of at least the component (b). Because of this, a nonwoven fabric laminate can be obtained that has good formation and excellent softness, gas permeability and water impermeability. It is used suitably for sanitary goods such as disposable diapers and packaging materials.
