ABSTRACT:
A method and plant for producing an air-laid non-woven web of cellulose fibers or of cellulose fibers mixed with synthetic fibers that includes at least one air-laying section for depositing fiber fluff into a layer upon a forming wire, an overlying second wire for transferring the layer of fluff to a third wire having a mesh count small enough for preventing the fibers from penetrating into the wire, and at least one nozzle for directing a water jet towards the fluff on the third wire, thereby hydroentangling the fluff into a coherent web. By the method and plant according to the invention, it is possible to produce hydroentangled fiber webs which are less expensive and have better absorption properties than hitherto known. The webs can be produced with weights between about 20 and 2000 g/m2.
