Fremgangsmåte for fremstilling av et jetfiltet materiale med foröket våtstyrke og jetfiltet materiale oppnådd ved fremgangsmåten

摘要

Hydro-entangled nonwoven material which, after the hydro-entanglement, is subjected to plasma or corona treatment with a view to increasing the wet strength of the material. It is believed that the surface of the fibres is modified by the treatment in such a manner that the fibre-to-fibre friction increases.
