Abstract (en)

[origin: EP0148033A2] An improved heavy-weight, nonapertured, nonwoven fabric of hydraulically entangled synthetic organic staple fibers has a unit weight of 200 to 850 g/m<2> [6 to 25 oz/yd<2>], a strip tensile strength of at least 0.26 (N/cm)/(g/m<2>) [5 (lb/in)/(oz/yd<2>)] and a resistance to disentanglement of at least 50 alternate extension cycles. The fabric is much stronger than such prior art heavy-weight nonwoven fabrics of hydraulically entangled staple fibers.
