This standard replaces GB/T3/14465-1984 - Determination of the color intensity and curvature of suspended vat dyes. The main changes of this standard compared with GB/T4166-144 are as follows: 1. Standard name: Determination of total color intensity and curvature of vat dyes; 2. Standardization report is added; 3. This standard is proposed by China Petroleum and Chemical Industry Association and is under the jurisdiction of the Technical Committee for Standardization of All-purpose Dyes (5A/TC134), Shenyang Chemical Research Institute. The main drafter of this standard is Ma Keqing. This standard was first issued in 1984.
Determination of the light intensity and intensity of the dyeing of vat dye-sensitive emulsion This standard specifies the determination method of the monochromatic light intensity and intensity of the dyeing of vat dye-sensitive emulsion. This standard is applicable to the determination of the light intensity and intensity of the dyeing of vat dye-sensitive emulsion. 2 Normative referenced documents

After the roller machine is used for room car production, the state Yi number of materials is set according to the correct liquid rate of 60%--S5 long, keep the working force, and the roller of F roller is ready for use.
The shrunk fabrics are respectively shrunk on the adjusted roller car for two singles, 30 times, and the loss is maintained at 50x~-65%
6.1.3 Drying
Transfer the dyed sample to the oven for drying. 6.1.2 Multiply the sample
Take a 4m×10cm piece of dye from the middle average part, number it, and wait for the reduction solution to flow. 6.1.5 Preparation of wet stain reduction solution 6.1.5.1 Preparation of reducing solution In each liter of water: a) Sodium carbonate: 258: 618% hydrochloric acid: 23% sodium fluoride: 10% sodium fluoride. The reducing solution should be prepared before use. 6.1.5.2 The wet stain reduction solution should be prepared before use. 6.1.5.2 The wet stain reduction solution should be prepared before use. 6.1.5.2 The wet stain reduction solution should be prepared before use. The dye should be taken out of the prepared original reduction solution separately, and the surface of the stain should be fixed with 23% of the stain. Then, transfer the wet stain to the prepared polyethylene film separately, and make sure the stain is neatly arranged. There should be 1 meter between each stain. Make a thin film on top and exclude the air. After the stain is separated from the paper, press the upper and lower films together under the glass melting press to make the sample a vaporizer. E.1.9 Steam
Rapidly transfer the prepared samples according to 1.5 of this standard into a laboratory steamer preheated to 13°C, and transfer to a plate for drying at 123°C.
6.1.7 Oxidation
Transfer the steam to a bottle containing 28% sodium 28 and 7% ice. Oxidize it at room temperature to 1500 nm. Take the soap and cook it with running water until it is completely washed. 6.1.8 Washing the soap
After the soap is fully washed with running water, cook it in a new water-free soap filter containing 5g of sodium 28 and 38% of sodium 28 (at a bath ratio of 1:20) for 5 min. 6.1.9 Drying After the dyeing sample is dried with water, the sample is dried under the following conditions. 6.2 Evaluation of color results According to the relevant provisions of Chapter 5 of GH/T4466-1, 4 and 5 of GH/T12374-1. 2 Test report The test report shall include the following contents: Name of the tested material, number of this standard, year and depth of dyeing; Name and model of the instrument used; Test results; Special conditions in the test; Differences from the test method 1 Test period.
