Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for treating a long fabric under high pressure and moist heat, such as pretreatment,
Continuous moist heat treatment of fabrics that improves the processing quality of long fabrics and further saves thermal energy to increase economic efficiency when dyeing, processing of ash content, etc. are carried out continuously. This relates to processing equipment.

Industrially produced fabrics are processed through processes such as desizing, scouring, dyeing, shrinking, and weight loss (hereinafter, these processes are simply referred to as 7).
In the method of continuously performing W heat treatment, it is known to use, for example, a high-pressure steamer developed by the present inventor. A treatment liquid (caustic liquid for pre-treatment and weight reduction treatment, staining liquid for dyeing treatment) is placed in a liquid tank installed externally or in a liquid sealing tank formed in the artificial side sealing mechanism of the high-pressure steamer. The cloth to be treated is passed through the chamber (such as
The target process is carried out by repeating the hydration process.

However, in the above-mentioned continuous moist heat treatment method for high-pressure steamer 1, the saliva liquid tank installed outside the steamer is placed at room temperature, so the temperature of the liquid in this liquid tank is also at room temperature. It becomes. Therefore, the fact that the liquid temperature in this liquid tank is at room temperature means that the liquid temperature is at a high temperature.
Since the permeability of the liquid into the fabric is poor, there is a drawback that the liquid content is insufficient or the liquid content is uneven. In order to overcome this drawback, it has been proposed to heat a liquid tank placed outside the steamer, but in this case, a problem arises in that a heat source for heating the liquid tank is required.

In addition, during operation of the high-pressure steamer, that is, during processing, the fabric introduction-side seal provided on the high-pressure steamer can (2) and the fabric outlet-side seal mechanism are maintained. The structure is such that pressurized air is continuously supplied into the inlet seal mechanism, and the mixture of air and steam mixed within the seal mechanism is sequentially exhausted, reducing waste of thermal energy. was occurring.

The present invention has been made in view of the above, and it is possible to heat and maintain the liquid temperature in the processing liquid tank installed outside the high-pressure steamer can at a constant temperature, and to apply the same to the fabric before being supplied into the steamer can. By impregnating the fabric with a high-temperature treatment liquid, it is possible to improve the uniform permeability of the treatment liquid into the fabric. Furthermore, in the present invention, high-temperature gas discharged from a high-pressure steamer can or a dryer is used as thermal energy to maintain the temperature of the liquid in the processing liquid tank at the farm temperature and a constant temperature. In addition to improving the economic efficiency of thermal energy for processing, a constant-temperature processing solution can always be obtained without using a solution temperature sensor.

The present invention will be explained in detail below based on embodiments shown in the drawings.
