POLYETHYLENE NONWOVEN FABRIC AND NONWOVEN FABRIC LAMINATE CONTAINING THE SAME

摘要

A polyethylene nonwoven fabric which is formed from a resin composition comprising polyethylene (A) and a polyethylene wax (B) by the melt-blowing process. The fabric has a small fiber diameter and a satisfactory texture. A nonwoven fabric laminate having at least one layer of the nonwoven fabric is excellent in flexibility, water resistance, and interlaminar adhesion. In particular, a laminate comprising the polyethylene nonwoven fabric, as a melt-blown nonwoven fabric, and a spunbonded nonwoven fabric composed of composite fibers obtained from a propylene polymer (a) and an ethylene polymer (b) has satisfactory evenness and is excellent in flexibility, air permeability, water resistance, and interlaminar adhesion strength. This laminate is suitable for use as a material for sanitary materials such as paper diapers and as a packaging material.
