あった。For example, when continuously dyeing a long length of industrially produced fabric, the fabric to be dyed is impregnated with a dye solution adjusted to a predetermined position, and then subjected to the desired dyeing process by heat treatment or the like. It is known to do so. However, during the above-mentioned dyeing process in which the dye solution is impregnated into the fabric, the amount of water supplied to the liquid tank depends on the adsorption of the dye in the fabric, the moisture absorption of the amount of fabric, the capacity of the padding tank, the speed of dyeing, etc. The concentration of the dye solution changes over time, and as a result, a problem arises in that it is difficult to uniformly dye the entire length of the fabric from the beginning of the fabric to the wood ash. Therefore, in the above-mentioned dyeing process, it is necessary to always apply a dye solution of a constant concentration to the fabric that is continuously transported to impregnate it. The concentration of the dye is measured based on the data created by the dyeing engineer and visual experience, and based on this measurement result, the stock solution is replenished into the liquid tank and adjusted so that the aqueous solution in the g tank remains approximately constant. Was. However, with this *a method, the slight difference in the amount of dyeing is within the permissible range seen by the human eye and is often seen as a normal dyed fabric, but due to Since the density is not checked, there is no way to check whether the density is constant from beginning to end.Depending on the color type, there are colors that are slightly within the acceptable range, and there are many cases where the density is too high, so countermeasures are desired. It was something that

し、この発明に至ったものである。The light transmittance of the dye solution differs depending on the degree of a, and the transmittance type increases as it gets lower and the density can be determined by reading the transmittance with a detector.The contrast of the light transmittance varies depending on the color type. However, it was discovered that the light transmittance of each color sharply increases or decreases depending on the density difference at a specific density, which led to the present invention.

法を提供することを目的とするものである。Specifically, the present invention focuses on the fact that the light transmittance of each color dye differs depending on the color of the dye, and the dye concentration in the dye bath is constantly detected by light transmission. If the concentration index of the dye solution in the dye bath is fluctuating from the desired concentration index, manually or automatically add the dye or water solution so that the concentration index approaches the desired value. Therefore, it is an object of the present invention to provide a method for detecting the concentration of a dye solution in a dye padding tank, which allows a constant concentration of dye solution to be always ensured in the tank.

調整されるものである。Next, to show its effect, the amount of light received by the light receiving element varies depending on the concentration in the dye solution, and in the light transmittance index meter, the amount of light received by the light receiving element varies depending on the concentration in the dye solution, as shown in Table 1 above. An index corresponding to the dye concentration is displayed. Therefore, the concentration in the liquid tank is clearly displayed on the index hand. Based on the value shown on this index hand, if the concentration is higher than the desired concentration, water is added to obtain the desired fIk degree, and if the a degree is less than the desired concentration. Addition of dye liquor, either manually or automatically, will always result in a constant volume of dye solution. In the case of automatic liquid addition, if the concentration is clear based on the output from the light transmittance index meter 8, for example, a relay (R)i) is operated and a solenoid valve (S
V2) is opened, and as a result, an appropriate amount of water is supplied into the liquid tank 1. Also! If the concentration is weak, the relay (RL) operates and the solenoid valve (SVI) opens, and the appropriate dye solution is supplied into the tank 1, and the dye solution in the tank 1 is always kept at a constant level automatically. It will be adjusted.

Extremely accurate concentration measurements can be achieved compared to visual judgment. Furthermore, it is possible to control the addition of the dye solution and water solution based on the measurement index, so it is also possible to automatically control the LK degree of the dye solution in the dyeing tank to a constant value, and the fabric There is an effect that a uniform amount of dyed cloth can be obtained throughout the continuous dyeing process.
