摘要
The conventional method for production of a multiple-layer, non-woven fibre is by means of the air-lay method, with thermal bonding using bonding fibres. The same method can be applied to a composite non-woven fibre with an intermediate pulp layer. This method of bonding does not reduce the later pilling wear and hardly influences the inner composition of the layers of the composite. According to the invention, the outer non-woven fibre is preferably made from a bicomponent fibre and treated by hydrodynamic needling for bonding, such that not just the surface is bonded, but also the layers are bonded to each other.
