FIELD: textiles, paper.SUBSTANCE: fabric structure for use as a tape or a sleeve for obtaining textured nonwoven materials, permeable to air and/or water, comprising: a carrier substrate, a surface of contact with the web, having a pattern comprising a number of raised contact pads and recesses, for imparting texture to the nonwoven material, and a number of voids for passage of water and/or air from the fabric surface into and/or through the structure. At that the effective diameter of the said voids is more than 50 microns, and the contact surface with the web comprises the material of surface comprising a coating or a layer of the laminated film, at that in the said coating or film the grooves are formed, and the barrier layer under the surface of contact with the web of the said fabric structure, which enables the surface material to penetrate partially into the substrate under the surface of contact with the web.EFFECT: obtaining textured nonwoven materials, permeable to air and/or water.67 cl, 27 dwg |
