摘要：
The invention provides a nonwoven fabric of stretched filaments of different kind polymers, having a strength equal to that of a woven fabric and features including an elongation, a uniformity, good feeling, a bulkiness and a thinness, characterized in that the nonwoven fabric is provided with stretched filament webs comprising long filaments formed out of a plural kinds of thermoplastic polymers of different properties, the long filaments as a whole being aligned in one direction, and a method for manufacturing the same. The invention provides also a nonwoven fabric of stretched filaments having a high strength as well as a high bulkiness and comprising different kind polymers which is provided with a first web layer of crimped filaments and a second web layer of substantially non-crimped, stretched long filaments, and a method for manufacturing the same.
