Abstract
The present invention relates to a method for producing spunlace material in which there is formed a fibrous web by air-laying a layer of fibres of staple length on a forming wire and air-laying a layer of short fibres on top of the layer of staple fibres. According to the invention, the fibrous web is passed to an entangling wire 18 on which there is arranged at least one elongated element 17 whose diameter is much greater than the diameter of the wires 16 in the entangling wire 18, whereafter the fibrous web is entangled. The invention also relates to an arrangement for carrying out the method, and to a spunlace material produced in accordance with the method.
