SU119650A1 - Apparatus for applying and fixing fibers on textiles, paper, etc. in the production of, for example, artificial suede - Google Patents

Description

Known inserts for applying and attaching fibers to textiles, paper, etc., in the manufacture of, for example, artificial suede. Such plants typically consist of a fiber bin; a tape transnorter located under the bunker and intended for moving the fiber falling onto it from the bin; two electrodes between which the upper branch of the conveyor does not stand; devices for moving the processed material between the electrodes and the dryer. A knife is typically used to limit the amount of glue applied to the material.

When such high-voltage DC units operate, there are large electric leakages through the non-working parts of the electrodes, the conveyor and the ionized air in contact with the metal parts of the installation, as well as the loss of fiber carried in different directions by the ionized air.

The described installation allows to reduce fiber losses and power consumption, and also provides a more uniform coverage of the material being processed. For this purpose, the electrodes are made of conductive polystyrene and insulated on all non-working sides, and the working part is made convex. The conveyor belt consists of a series of conductive strips insulated from one another.

To obtain a multicolored material in the installation, insulating screens have been applied, which are placed on the conveyor belt and cover the material in certain areas for possibly 1; subsequent coating of these areas with fibers of a different color.

FIG. 1 shows the installation diagram; in fig. 2 - section of the conveyor belt; in fig. 3 - electrode; in fig. 4 - screen.

 119650-2

The Jy rig includes a fiber 1 for fiber; a belt conveyor 2 made of a series of conductive strips 3, for example, of a current-carrying neck of rubber, isolated one from e) an insulating insulating material i 4; electrodes 5 and 5 of the conductor W, its polystyrene, insulated with B; all non-working sides, with the working part of the upper electrode 5 being convex; a device 7 for moving the processed material 8; a dryer 9 for infrared irradiation of the material being processed; and a knife 10 for limiting the amount of glue applied to the material, also made of an insulating material, such as Plexiglas.

For the manufacture of material with different colors, insulating screens / U are applied, laid on the conveyor and covering the material in certain areas with the subsequent coating of these areas with fibers of a different color.

The material to be processed 8, with glue applied on its surface, the surplus of which is removed by the knife 10, is fed to the device 7 between the electrodes 5 and 6, to which a high-voltage constant electric current is applied. At the same time, the fiber falling out of the bunker / onto the conveyor 2 is also fed between electrodes 5 and 6.

Under the action of an electric field, the fibers are moved to the material 8 to be processed and adhere to its surface covered with glue, after which they are fixed on it in the dryer 9.
