Abstract

This invention relates to a non-contact coating method for producing a continuous coating and articles constructed therefrom. This invention further relates to a method for producing a textile material with a moisture-impermeable barrier layer and to a method for producing a moisture-absorbing article of hygiene which has such a barrier layer. This invention particularly relates to a textile material and hygienic disposable articles comprising a body fluid impermeable barrier layer which can be produced from a non-contact coating method. Preferably, the thermoplastic composition used for producing the barrier layer exhibits certain rheological characteristics and comprises at least one homogeneous linear or substantially linear interpolymer of ethylene with at least one C.sub.3 -C.sub.20 alpha-olefin, further characterized by each said interpolymer having a polydispersity less than about 2.5.
