Abstract
A polyethylene nonwoven fabric is produced by the meltblowing process using a resin composition comprising a polyethylene (A) and a polyethylene wax (B). The fabric is made up with fine fibers having a small fiber diameter and good formation. A nonwoven fabric laminate containing at least one layer comprising the polyethylene nonwoven fabric is excellent in softness, water impermeability and interlaminar bond properties. In particular, the laminate of a meltblown nonwoven fabric comprising the polyethylene nonwoven fabric and a spunbonded nonwoven fabric made up with a conjugate fiber comprising a propylene-based polymer (a) and an ethylene-based polymer (b) provides good uniformity and excellent softness, gas permeability, water impermeability and interlaminar bond strength. The laminate is advantageously used as substrate materials for sanitary goods such as disposable diapers and for packaging materials.
