Method for production of non-woven fabric

摘要

A method for fiber entangling of a fibrous web by subjecting said web to a treatment by high velocity water jets on support members, in which said support members comprise a water-pervious support member and water-impervious support member arranged in contact with the lower surface of said water-pervious support member. As said water-pervious support member, a porous screen or a plurality of belts spaced from one another transversely of the fibrous web and as said water-impervious support member, members each having a flat or circular surface on which the web is supported are employed. Preferably, these support members are arranged in a preliminary treatment station for the fibrous web.
