TEXTILE TYPE TEXTURIZED NONWOVEN FABRIC, CONTAINING PAPER FORMING FILAMENT, CALENDER ROLL AND MATERIAL MANUFACTURING METHOD Russian patent published in 2017 - IPC D21H25/00 D21H27/02 B31F1/07 D01H1/00 

FIELD: textile, paper.

SUBSTANCE: calender roll is used to produce the texturized nonwoven material, containing the paper-forming filament. The calender roll includes a protruding relief, that includes: a base element, having the ring shape, at that the ring defines a top relative to the central part of the ring, defining the recess and the grinded surrounding area, at that the ring containing at least one radial channel, providing the recess communication with the grinded surrounding area in such a way to determine the discrete calendering surface; repeating of the specified base element along a plurality of rows and columns, substantially along the entire peripheral surface of the calender roll, at that the repeating is being regular, with the exception of a plurality of substantially longitudinally oriented parts and transversely oriented parts, at that the mentioned parts have limited size with respect to the size of the calender roll and are optionally distributed so as to define a plurality of the optionally distributed longitudinal and transverse lines in the texturized nonwoven material, containing the paper forming filament, forming a visually textile type texture.

EFFECT: creation of the texturized nonwoven material, containing the paper forming filament, having the appearance of the textile type material with high quality, improved aesthetic characteristics.
