Abstract

The invention relates to equipment for dyeing and finishing production of enterprises in the light and textile industries, allows to improve the quality of the material and expand technological capabilities. The device contains transporting rollers located in the heat chamber for conducting material through them. Perforated plates are mounted one above the other under the rollers. The lower plate is inclined with decreasing clearance relative to the heat transfer medium under the plate. The end of the inclined plate is pivotally mounted to change its angle of inclination, which allows for different materials to control the amount of coolant in different zones of the heat chamber 1

Description

The invention relates to equipment for dyeing and finishing production of enterprises in the light and textile industries, in particular to plants for the heat treatment of textile materials to fix dyes on them.

The purpose of the invention is to improve the quality of the material and expand technological capabilities.

Figure 1 shows a device, a longitudinal section; in Fig.2 - section aa in Fig.1; in Fig.Z - node I of Fig.1

The device for fixing dyes on textile material consists of a heat chamber 1, upper 2 and lower 3 conveying elements, for example, rollers, a duct 4 for supplying heat medium to the heat chamber 1, perforated plates 5 and 6. mounted one relative to another with a variable gap, the upper one being perforated the plate 5 is installed horizontally under the lower rollers 3 The lower perforated plate 6 is mounted in relation to the upper one with an inclined gap, which increases from the point of entry of the coolant to the opposite wall of the heat chamber. A bottom perforated plate is fastened to this wall by hinge joint 7. The perforation in the inclined plate is such that the living section in the plate for the passage of heat medium changes along the length of the chamber. Fig. 1 shows that the live section for the passage of heat carrier on the supply side of the textile material is larger than on the opposite side. For this, holes 8 in the plate are made of a larger diameter than holes in the opposite part of the lower perforated plate

The device operates as follows.

Textile material printed with dyes is fed into a heat chamber 1 where

the upper 2 and lower 3 rollers ensure the movement of textile material to the place of unloading from the heat chamber and a change in the direction of its movement. The coolant (heated air, heated humidified air, heated gas or another type of coolant) is fed by duct 4 under the lower perforated plate 6. Perforated plate 6 is made with

different live sections for the passage of coolant, which allows you to adjust the required amount of coolant for one or another part of the textile material. The bottom perforated plate 6 has

the ability to move around the axis of the swivel joint 7. When lowering the lower perforated plate 6, increasing the gap between the plates increases the amount of coolant that is supplied to the textile loading zone through the upper perforated plate 5.

Thus, the proposed device allows you to supply coolant with the parameters necessary for

the process of fixing dyes on a textile material underneath the lower conveyor rollers braided with textile material.

Using the invention, various dyes can be fixed on different textile materials due to the ability to control the amount of coolant in different areas of the heat chamber, i.e. expanding the technological capabilities of the proposed device. Due to the optimal supply of coolant, the quality of the material improves - it increases to 1-4% fixation of dyes. In addition, an optimal supply of heat carrier allows the process to be carried out with minimal energy consumption and to reduce the specific heat consumption. (56) German Patent N 514003,
