摘要：
Disclosed herein is a fibrillated weatherproof web having a network structure, which can be produced with ease and is economical. The web comprises a multilayer composite film composed of at least two layers, one being a first layer (I) made of a first thermoplastic resin and the other a second layer (II) made of a second thermoplastic resin having a melting point lower than the first thermoplastic resin and containing at least 300 ppm of a light resistance imparting agent. A number of slits have been formed in a longitudinal or transverse direction. The web has been oriented at a draw ratio in a range of from 1.1 to 15 times. A nonwoven fabric making use of one or more fibrillated webs of the above sort and processes for the production of the web and nonwoven fabric are also disclosed.
