ABSTRACT:
The present invention relates to a nonwoven fabric including a fine denier filament having a plexifilamentary structure in which the disadvantages of polyolefins and of polyesters are offset each other while advantages of them are well utilized with a fine fibrillated structure comprising said filament. The filament comprises a mixture which is at least composed of polyolefin and polyester which are immiscible with each other and has a plexifilamentary structure. The filament is so highly fibrillated that the fibril has not been available yet and, in addition, the filament is with high strength and modulus and exhibits a good dyeing ability. The above-mentioned nonwoven fabric contains the filaments having a plexifilamentary structure in which a mixture of polyolefin and polyester which are immiscible with each other in a mixing ratio within a range of from 5/95 to 95/5 by weight and said filaments are entirely or partially bonded. Said nonwoven fabric is with excellent strength, moisture permeability and waterproof pressure and exhibits a dyeing ability.
