Note that the production bottles are kept for reference.
5 Test method
5.1 Determination of appearance
Visual determination is adopted.
5.2 Determination of dyeing shade and intensity
Name, product name, batch and sampling date. One bottle is used for inspection. The general conditions for dyeing shall be carried out in accordance with the relevant provisions of GB/T2374 and GB/T2376. 5.2.1 Dyeing depth and fabric treatment
The dyeing depth is stipulated as 3%, and 5g cotton yarn (or cotton cloth) is used for dyeing. Before dyeing, the weighed cotton yarn or cotton cloth is boiled for 10 minutes with 0.02g/L penetrant BX (industrial use) at a bath ratio of 1:20. After treatment, wash with clean water and squeeze out excess water for later use. 5.2.2 Preparation of dye bath
Weigh 1.5g of the test sample and standard sample (accurate to 0.0005g), mix with 15mL of 100g/L sodium sulfide (calculated as 100%) solution [dye: sodium sulfide (calculated as 100%) = 1:1] and 1mL of 50% Turkey red oil to make a slurry, add 50mL of distilled water, and then heat the dye solution to 90-95℃, keep it warm for 15min, and after it is completely dissolved, add 200mL of boiling distilled water, stir well, and transfer it into a 500mL volumetric flask after cooling, and dilute it to the scale with distilled water. The dye solution used for each dyeing must be prepared as it is used. In five 300mL dye vats, prepare the dye bath according to the provisions of Table 3. Table 3 Preparation of dye bath
