RU162366U1 - DEVICE FOR ACTIVATING A SURFACE OF FABRICS FROM PLANE POLYMER FIBERS AND NONWOVEN MATERIALS WHEN PRINTING - Google Patents

Abstract

The device for activating the surface of fabrics made of flat polymer fibers and non-woven materials when printing, including a liquid container, a conveyor and an endless tape of porous material placed on the tape-driving shafts, characterized in that it further comprises a heated shaft with a prominent relief pattern and a pressure shaft, and a porous the endless tape is made of a lyophilic heat-resistant material, insoluble and not swelling in organic liquids.

Description

The technical field to which the proposal relates

The proposal relates to the field of engineering and technology for processing textile and non-woven materials from thermoplastic synthetic fibers for printing on roll printing equipment.

State of the art

A device for activating the surface of fabrics and canvases is known, which comprises a bath for impregnating liquid, two or more transporting drums arranged sequentially along the movement of the impregnated sheet in the bath, two endless belts for transporting the sheet, placed on tape guiding shafts and made of porous material in the form of nets , as well as plates immersed in the bath and installed both above and below the plane of movement of the canvas. (RF patent 2157868, IPC D21G 7/00, published. 20.10.2000)

The disadvantages of the known device are:

- the impossibility of its use for the preparation of textile and non-woven materials from thermoplastic synthetic fibers for printing on roll printing equipment, because hydrophobic elastic fibers prevailing in the surface layer are not wetted by paint and destroy its layer.

- the impossibility of compaction and lyophilization of the surface layer of the canvas only due to the application of a known device to a liquid.

The essence of the proposal

The technical problem to be solved is the alignment of the structure, compaction and lyophilization of the surface layer of a web of thermoplastic synthetic fibers for printing

The problem is solved in that the device for activating the surface of fabrics made of flat polymer fibers and non-woven materials, including a liquid container, a conveyor and an endless belt of porous material placed on the tape drive shafts, according to the proposal, further comprises: a heated shaft with a prominent relief pattern and a pressure shaft and the porous endless tape is made of a lyophilic heat-resistant material, insoluble and not swelling in organic liquids.

The utility model is illustrated by the device diagram.

FIG. 1. - Diagram of a device for activating the surface of fabrics made of flat polymer fibers and non-woven materials when printing.

1 - endless tape made of heat-resistant porous material; 2 - pulling and guide shafts; 3 - moisturizing shaft; 4 - bathing shaft; 5 - capacity; 6 - organic liquid; 7 - a heated shaft; 8 - relief pattern; 9 - clamping shaft; 10 - working section of an endless tape; 11 - a directing shaft; 12 - a roll of sealed fibrous material; 13 - sealed fibrous material; 14 - receiving sleeve.

Description of the device in statics An endless tape made of heat-resistant porous material (1) tucked into a tape drive mechanism consisting of pulling and guiding (2) shafts. The tape touches the moistening shaft (3) in contact with the shaft (4) bathing in liquid. The moistening shaft (3) and the bathing shaft (4) are placed in a sealed container (5) with an organic solvent liquid (6). Inside the ring of the endless belt there is a heated shaft (7) with a protruding embossed pattern - a stamp (8), and on the opposite side a clamping shaft (9) is installed. In the contact zone, there is a working section of a porous endless ribbon (10), onto which a sealed fibrous material (13) is fed through a guide shaft (11) from a roll (12) through a receiving sleeve (14) in the direction of the printing sections of the printing equipment.

Description of the device in dynamics

The rotation of an endless ribbon of heat-resistant porous material, for example, fluoroplastic (1), the rotation of the heated shaft (7) with a relief pattern (8) and the pulling of the printed material (13) from the roll (12) onto the receiving sleeve (14) is synchronized with the operation of the printing sections printing equipment, so that the paint is applied to the fibrous material in those places that are processed with a hot stamp (8) through a section of an endless tape (10) moistened with a solvent, for example, toluene (6) entering its porous structure at contact with a moistening roll (3), the surface of which is covered with a layer of solvent filling the tank, for example, toluene (5). A section of the endless tape (10) is pressed against the sealed material from a mixture of polypropylene fibers and low-melting polyester fibers, heated, for example, to 120 ° C with a die (8) under pressure, for example, 0.5 MPa, for a time sufficient to compact the nonwoven fibrous structure web - 1 ÷ 3 s and saturation of its surface with an activating adhesion solvent. Sections of the activated surface of the fibers of the material partially desorb the solvent and enter under the printing sections of the printing equipment, which successively apply layers of ink on top of each other or end-to-end, depending on the type of printed pattern.

Claims (1)
