ARTICLE HAVING COMPONENT MADE OF NONWOVEN FABRIC, WHEREIN FIBRE ELEVATION IMPROVING FASTENING FIGURES AND CONFIGURATIONS ARE FORMED BY CALENDERING Russian patent published in 2015 - IPC A61F13/15 

FIELD: chemistry.

SUBSTANCE: disclosed is an article having, as a component, a piece of nonwoven fabric formed primarily from polymer fibres. The piece of nonwoven fabric can have a configuration of fibre-consolidating fastening points stamped on its surface. The fastening points can have the shape of at least one figure, and such a figure can have a periphery with the greatest measured length and the greatest measured width. The periphery can have a curved part and a ratio of the length to the width of at least 2.5. The fastening points also have a certain density of arrangement and orientation relative to the direction of movement of the fabric in a machine and a cross direction. The shape of the fastening point reflects the shape of the corresponding fastening protrusion on a fastening roller.

EFFECT: shape, density and orientation of fastening protrusions influence the flow of air through the fastening gap, and said flow can be used to improve elevation of fibres of the obtained fastened nonwoven fabric.
