Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for continuous moist heat treatment of a fabric, which allows uniform liquid treatment to be continuously performed over the entire surface of a long fabric. be.

Conventional methods (e.g., scouring, bleaching, weight reduction, dyeing, resin processing, etc.) of continuous wet heat treatment (e.g., scouring, bleaching, weight loss, dyeing, resin processing, etc.) of large quantities of long fabrics that are industrially processed and produced (for example, the method developed by the inventor of the present invention) It has been proposed to carry out the desired processing using continuous moist heat using a wet heat reaction chamber, such as a 7-ji (black market name) or a high pressure steamer.
The conventional continuous moist heat method for long fabrics is
First, the fabric to be treated was immersed and passed through the treatment solution in a treatment solution tank installed outside the heat and humidity reaction chamber at ℃, and then the excess liquid from the liquid-impregnated fabric was squeezed out using a rouge. After that, intermediate drying is performed to prevent the liquid beads impregnated into the fabric from adhering to snow and the seal roll of the wet heat reaction chamber. Supply the steam into the steamer can (1'!11 thermal reaction chamber) and heat the steam to 3'C.

However, in the conventional wet heat treatment method, the fabric is immersed in the liquid at 6L (degree Celsius) in the liquid impregnation process before the steel rinsing, and then pulled out of the liquid and squeezed at 0℃. Since the liquid is squeezed, uneven squeezing occurs during the liquid squeezing process.Also, after the liquid squeezing, the liquid concentration σ) changes, and there are problems such as not being able to apply a fresh liquid at a constant concentration.

In addition, with the conventional aperture 0-le, the extraction rate is low, so the aperture D
-I was unable to extract enough liquid even though I passed it through the tube.

In the case of R5, uneven processing occurs due to liquid dripping on the surface of the fabric after passing through the squeezing roll, or because the fabric has a high water content, the heating effect on the fabric is poor and it takes a long time for the reaction of the liquid to complete. There were a number of problems, such as the high cost.

The present invention has been made to solve this problem, and by sequentially applying as much liquid to the fabric to be treated as the fabric absorbs, and impregnating the fabric with a small amount of moisture. By always impregnating the fabric with a fresh treatment liquid in a fixed amount, liquid waste is eliminated and the effect of increasing the temperature of the fabric is enhanced. In addition, by using dry heat as an intermediate drying means for the fabric that has been impregnated with liquid, it is possible to prevent the liquid layered on the surface of the fabric from falling off, and further shorten the reaction completion time of the liquid, that is, to speed up the temperature rise of the fabric and dry the liquid. This improves the speed of processing.

The present invention will be explained in detail below based on the embodiments shown in the drawings, and the present invention is intended for continuous scouring, whitening, dyeing, purisito coloring, resin processing, and weight loss processing of fabrics. Although this method can be applied to moist heat treatment, this example describes dyeing of fabric.

Reference numeral 1 denotes a vertical heat treatment tower, and a heating chamber 2 is formed in the lower part of the heat treatment tower 1. A heating chamber 2 is formed in the lower part of the heat treatment tower 1. An electric heating heater 5 is installed to apply dry heat. Further, a humidifying nozzle 7 for applying high-temperature liquid to the fabric 4 transferred by a kite roller 6 for pulling up the fabric 4 is arranged above the inside of the heat treatment tower 1. 8
are a pair of liquid applying rolls provided below the fabric inlet 3, and a liquid receiving tray 9 is arranged below these liquid applying rolls 8 as close as possible. 1o is a dye liquid supply tank for sequentially supplying a fixed amount of dye liquid to the liquid receiving tray 9, that is, as much dye liquid as is absorbed by the advancing fabric.

Reference numeral 11 denotes a wet heat treatment chamber that is provided following the heat treatment tower 1. Inside this wet heat treatment chamber 11, there is a guide roll 12 for making the fabric meander, and a guide transport is carried out by the kite roll 12. A humidifying nozzle 13 for applying high-temperature liquid to the fabric 4 is provided. And these humidifying nozzles 1 to 13 and the above-mentioned humidifier l, ]? The nozzle 7 is connected to a high-temperature liquid generator 14 described below, and high-hot water of 100° C. or higher (for example, 150° C.) is spouted toward the fabric 4 from these nozzles.

The high-temperature liquid generator 14 has a sealed can body 15.
, a steam supply '16 for supplying high-pressure steam into this can body 15, and an internal pressure automatic adjustment valve 17 for keeping the steam pressure inside this can body 15 constant, which are used as required. A drain valve 18 is provided. Reference numeral 19 denotes a liquid heating tube arranged in a meandering manner within the can body 15;
One end of the liquid heating pipe 19 is connected to the humidifying nozzle 7.13, and the other end of the liquid heating pipe 19 is connected to a hot water tank 21 via a pipe 20. 22 filters the hot water discharged from the moist heat treatment chamber 11, and sends the hot water from which impurities have been removed to the hot water tank 21.
Although this is a rotary filtration machine for storing water inside the tank, this offshore filtration machine is not the gist of the present invention and a filter with an appropriate structure can be selectively used, so a description of the structure of the offshore filtration machine will be omitted. .

Further, the humidifying nozzle 7.13 is a porous nozzle which has already been applied for and is extruded under pressure.

The above is the structure of the non-embodiment, but next we will discuss its operation.
To explain, first, pressurized steam is supplied to the steam supply layer 16 in the can body 15.
7, and the inside of this can body 15 is, for example, 5ψ' crn.
The surrounding air of high-pressure steam is maintained at a temperature of about 150° C., and heated for tJl to generate heat overnight.Therefore, the fabric 4 is continuously transferred and guided into the liquid receiving tray 9. Then, the fabric 4 is impregnated with the dye liquor from the dye liquor supply tank 10, which has the effect of impregnating the fabric 4 with the dye liquor.
