Abstract

PURPOSE: To prevent cloths from being damaged and efficiently carry out the level dyeing by applying a dye liquor jet stream under different nozzle pressures according to the thickness of the different cloths and passing the cloths through pipes of different flow passages so as to provide different passage speeds. CONSTITUTION: This apparatus is capable of efficiently carrying out the level dyeing of cloths by designing the apparatus to spray a dye liquor under no pressure from a dye liquor nozzle under no pressure (a low-pressure nozzle 9) on the cloths utilizing a head when dropping the cloths, e.g. a heavy-gage cloth and a fine material from a guide roller 8 according to the thickness of the different cloths, pass the cloths through a single pipe and single flow passage pipe 5, introduce the cloths into a dye bath and dye the cloths for the heavy- gage cloth and the fine material or accelerate the cloths of a light-gage cloth or a fine yarn material with a jet stream of the dye liquor heated with a pressurized dye liquor nozzle (a high-pressure nozzle 10), introduce the cloths from a pipe flow passage of a single pipe and a double flow passage pipe 4 into the dye bath and dye the cloths.

Description

[Detailed description of the invention] The present invention relates to the design of dyeing machines.

Because the fabrics have different thicknesses and fibers, if the fabrics are treated under the same dyeing conditions, the results will be either over-dyed or under-dyed, which is difficult to quantify. Fabrics of different thicknesses, fiber lengths, and weaves can be dyed using the same dyeing machine, and in order to achieve uniform dyeing, increase efficiency, and avoid damaging the fabric materials, the current dyeing machines are There is a real need to improve the structure-function part.

The best working characteristics of dyeing machines are how to achieve uniform dyeing,
The key is to get the maximum color out quickly. However, due to differences in the thickness of the cloth and the properties and shapes of the fibers, the relative movement conditions between the fibers and the dyeing solution required during the dyeing operation also vary. For the time being, even if we ignore other secondary conditions, as far as the two most basic conditions are concerned: passing speed and nozzle pressure suitable for the cloth, the properties and shapes of the cloth are different, so different machine structures need to be processed differently.

In other words, the same dyeing machine must have very different functional ranges. In order to obtain stability of function and convenience of operation in such a range, it is necessary to rely on a great deal of experience to obtain the ability of operation and adjustment, and in order to avoid this it is necessary to use the same mechanical structure. Shouldn't. The mechanical structure of each must also be such that operation is as simple as possible. With this in mind, the present invention has achieved this improved flow piping and nozzle through intensive research, design and experimentation.

The gist of the present invention is to apply dye atomization flow at different nozzle pressures to cloths of different thicknesses according to the characteristics of different fibers to make cloths from materials of different thicknesses, and to use different flow channels to obtain different passing speeds. The purpose is to increase dyeing and conditioning efficiency, prevent damage to fabrics, and improve the overall functionality of dyeing and conditioning machinery.

The invention will now be described by way of example with reference to the accompanying drawings.

Figure 2 is a side view of the dyeing machine.
Showing the lowered casserole car (1), the dye liquid automatic filter (2) and the chemical reaction tank (3) before dyeing, after the main pump (7) sends the dye liquid to the heat exchanger (6). The dye liquid is sent along the liquid sending vibrator (6) to a nozzle in the separate body (details will be described later). The single-tube dual-channel pipe (4) is useful for passing thin fabrics or silk products. The single medium channel pipe (5) is useful for passing delicate items such as pure cotton, sheared cloth, towel cloth, thick fabrics and intellectual textile items, all of which are regulated by the flow valves shown.

As shown in the schematic diagram of Fig. 3, when the dyeing process is carried out on thick cloth, the cloth to be dyed is
), the cloth passes smoothly due to its own weight, the water head between the cloth guide roller and the cloth feeder, and then the pressureless nozzle (9) passes through the heat exchanger (6).
) is dyed using the dyeing solution from the dyeing solution, and then the fabric passes through the single-tube, single-channel vibrator (5) and returns to the dyeing tank. Thick cloth, short fiber cloth, 4 and delicate cloth such as towel cloth, shearing cloth, pure wool, etc. are thick, dense, or extremely easy to peel off, so this structure is easy to damage the cloth material. Thickness in parts or! &Ii The processing characteristics of fine material cloth are to stabilize the speed of the cloth material passing through the nozzle, make the dye absorption homogeneous, and make the dyeing good.

As shown in the schematic diagram of FIG. 4, when dyeing a thin fabric, the fabric to be dyed enters the fabric feeder from the fabric guide roller (8) at an oblique angle, where it passes through the pressure nozzle (10). Jet dyeing is performed using the dyeing solution coming from the heat exchanger (6), and then the fabric passes through the single-tube double-channel vibrator (4) and returns to the dyeing tank. Light cloth fabrics are longer for the same volume and are therefore more likely to produce uniform dyeing, and fine yarn fabrics provide more uniform dyeing and faster circulation speeds. 1. Even if the jet pressure is increased, the fine thread fabric will not be damaged, so the speed at which the cloth passes through the jet nozzle can be increased, the time required for the dyeing process can be reduced, and more homogeneous dyeing can be obtained.
