FIELD: technological processes.
SUBSTANCE: invention is related to methods for moulding of multilayer material. Method includes installation of, at least, one internal layer between the first external layer and second external layer. At that specified fist external layer and specified second external layer, each one, contain nonwoven composite material, which includes thermoplastic fibers and absorbing staple fibers. At that absorbing staple fibers consist of more than 50 wt % of specified nonwoven composite material, and specified internal layer comprises nonwoven layer made of around 100 wt % of thermoplastic fibers. Then method includes ultrasonic lamination of specified internal layer, specified first external layer and specified second external layer. At that ultrasonic lamination provides for pattern surface texture on at least one side of multilayer material.
EFFECT: improved strength and softness of final product, improvement of absorbing property for wide use.
