DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fabric solvent scouring device. Conventionally, gray cloth, which is a fabric before scouring, contains oils and fats, dirt, perspiration, and other solid impurities, so these impurities are removed as a pretreatment before entering the fabric dyeing process. If necessary, a method of scouring with water was used, but recently a solvent scouring method using a chlorinated organic solvent or the like, which has good cleaning efficiency, has been adopted.

However, the former dry method (2) has the disadvantage that it is difficult to completely remove the solvent and water-soluble impurities cannot be removed, while the wet method (2) has the advantage of being able to remove the solvent. If water-soluble impurities cannot be removed and the cloth is shaken off from the scouring machine while still wet and heat-retaining, the cloth will pile up in a high temperature state, causing creases and mold. was there.

That is, the solvent scouring apparatus for fabric is characterized in that the solvent is evaporated from the cloth washed with a solvent in a hot water bath, and the solvent is evaporated and the scouring cloth is cooled while being shaken off to form a scouring cloth. The present invention will be explained in detail based on the drawings. FIG. 1 is a schematic explanatory diagram showing one embodiment of the solvent scouring apparatus of the present invention. In FIG. 1, a greige fabric 1, which is a cloth before being scoured, passes through a solvent bath 2 and is washed to remove oil and fat contained in the greige fabric 1. After washing, the solvent impregnated into the cloth is squeezed out by the squeezing device 7, and the cloth absorbs about 50 to 100% of the solvent (
Weight of cloth) is placed in hot water tank 3. The solvent contained in the cloth is heated and evaporated in the hot water bath 8 to be removed. On the other hand, cloth is also heated in hot water to the temperature of the hot water. The hot water-containing cloth discharged from the hot water tank 8 is squeezed by a squeezing device 7' and enters the cold water tank 4.

The feature of the present invention is that the desired effect is produced by evaporating the solvent in the hot water and cooling the heated cloth using a scouring device that uses a cooling tank between the hot water bath and shaking off the cloth. It is. Therefore, it is essential to provide a cooling tank.

When a hot water tank and a cold water tank are connected, if the cold water tank is installed higher than the hot water tank so that the cold water level is higher than the hot water level, the temperature of the hot water in the cold water tank will increase. Cold water warmed by the heat absorbed by cooling the heated cloth can be easily supplied by head without using a mechanical device such as a pump when used as make-up water for hot water.

Moreover, the warmed cold water can be used as make-up water for hot water. When using a single cooling tank, the temperature of the cooling water gradually rises due to the cloth heated to the hot water temperature, so it is necessary to constantly replenish cold water to keep the temperature constant. It must be disposed of, resulting in heat loss. Therefore, if a cooling tank consisting of multiple stages is used, the cloth at the temperature of the hot water coming out of the hot water tank will be cooled in sequence in many stages, and the cloth will be cooled as it passes through the stages, efficiently reaching the desired temperature. Z-heat can be effectively used.

The temperature of the hot water in the hot water bath is desirably lower than the azeotropic temperature of the solvent and water, and preferably 95° C. or lower, so as not to damage the fabric, in order to increase the effect of evaporating the solvent. To give a specific example, when 1°1,1-trichloroethane (boiling point 74°C) is used as a solvent, the temperature is preferably 65 to 80°C.

Aerating by blowing air into the cold water tank can speed up the cooling rate and remove fine impurities adhering to the surface of the cloth.

In the present invention, especially when woolen fabric is used as the cloth, if it is shaken off while it is hot and creases form, they will be set by the heat and will have to be repaired in the subsequent dyeing process, which will cause problems in the subsequent process. By using the cooling tank which is the device of the present invention, the prevention effect is remarkable. In addition, woolen fabrics contain sweat, dirt, starch, etc. in addition to oil and fat as dirt components, so mold is likely to grow when the temperature and humidity are high. This prevents the growth of mold.

As explained above, by using the scouring device of the present invention, the cloth that has passed through the hot water tank is sufficiently cooled, shaken off, and stacked, so that the scouring cloth does not have creases, wrinkles, or mold on the cloth. This has the effect of preventing troubles from occurring in subsequent processes, such as the dyeing process.
