SUBSTANCE: single-layer and multi-layer materials, manufacturing methods thereof and device for pressing thin paper layers are designed for producing soft absorbent design paper. Single-layer material made from thin paper consists of the first external surface and the second external surface. At that, design of the first surface is obtained during wet forming, and design of the second surface is pressed and imitating, which is obtained during wet forming. Multi-layer material made from thin paper contains at least two layers, including two external layers. Each external layer has the first surface and the second surface. One external layer has the design obtained during wet forming at least on the first surface. The other external layer has pressed design at least on the first surface, imitating design obtained during wet forming on the first surface of one external layer. Both external layers are brought together so that their corresponding first surfaces represent external surfaces of multi-layer material made from thin paper. Manufacturing methods are based on using the above materials and device for pressing thin paper layers. The latter consists of a pressing roller and supporting roller. Pressing roller has embossing design that corresponds to surface texture or negative of surface texture of fabric, woolen cloth, strip or roller used for forming the design on the layer, which is obtained during wet forming.

EFFECT: improving quality of material owing to improving its flexibility, smoothness, saturating capacity and absorption rate as well as reducing material prime cost.

SUBSTANCE: present invention pertains to a layer with an image meant for use in absorbent fabrics. An image is made, for example, in the form of a text or picture. An image is formed with a number of dots. When the layer is in the first state, the dots have the first surface density, which form an identifiable and clear image. When the layer is in the second and then outspread state, the dots have a second surface density, which is below the first surface density in the first state. In this case the image goes into the second surface state essentially indecipherable or unclear to the observer at the given distance because of a lower surface density.

EFFECT: obtaining the effect of reduction in visibility of the image on the fabric.

SUBSTANCE: present invention is related to method for manufacture of three-dimensional dyed macrorelief in canvas of ribbon flexible material. Technical result is achieved by method for manufacture of three-dimensional dyed macrorelief in canvas of ribbon flexible material, in which at first parts of device for relief creation are engaged with device for application of dye. Device for relief creation has three-dimensional macrorelief from alternating convex and deepened macroparts. Dye is applied on device for relief creation only on upper sections of convex macroparts. Then canvas is engaged with upper sections of convex macroparts coated by dye. At that canvas is dyed with creation of dyed macrorelief, which corresponds to structure of convex macroparts upper sections. At the same time this canvas is engaged with fastening device, which creates places of fastening in canvas, and also three-dimensional fastening zones that coincide with fastening places. Melt places are created by means of fastening device interacting with dye-coated upper sections of convex macroparts. Melt areas provide for creation of fastening places and three-dimensional fastening areas, together with dyeing of melt fastening zones and/or fastening places. In process of this operation three-dimensional dyed macrorelief is created.

EFFECT: provision of method for manufacture of dyed relief multi-layer canvas, which provides for creation of improved visual image of visible relief independently on layer thickness, but preferably for thin material.
