Disposable garment and elastic laminate employing nonwoven formed by bi-component fibers of ethylene-propylene random copolymer

摘要

The present invention is directed to a nonwoven composite laminate. In one aspect, the nonwoven composite laminate includes: a first nonwoven layer including component fibers containing an ethylene-propylene random copolymer which contains from about 7/mol% to about 15 mol% of ehtylene comonomer randomly distributed in the polymer backbone; and a second nonwoven layer joined to the first nonwoven layer. In another aspect, the nonwoven composite laminate includes: a first nonwoven layer including component fibers containing a smoothness oil and an ethylene-propylene random copolymer which contains from about 7 mol% to about 15 mol% of ehtylene comonomer randomly distributed in the polymer backbone; and an insulation layer joined to the first nonwoven layer for preventing the smoothness oil from permeating therethrough. These nonwoven composite laminates answer the need for a nonwven composite laminate which can reduce undesirable fuzz occurrence caused by friction applied thereto, while maintaining a soft "cloth-like" feel and touch.
