How to achieve good three-proof finishing effect? The master of the dyeing factory will teach you 12 points of practical knowledge
1. Start with chemicals
1. The three-proof finishing agent is a fine chemical composed of fluoride. Before finishing, make sure that the chemical container is clean and that no other softeners or other additives remain. agent.
2. Confirm that the product in the container should be properly stirred before use.
3. How to stir: Stir slowly, but not too slowly. The three-proof finishing agent must be re-dissolved into emulsion before use. Do not stir quickly, for example, using a high-speed mixer; because the emulsion will be sheared and damaged, resulting in demulsification and affecting the water-repellent effect.
Preparation of solution
4. Recommended preparation procedures:
a. Pour half of the required amount of water into the basin or into the feeding bucket .
b. Add citric acid or glacial acetic acid (pH value 5-6) to adjust the pH value of the water – check the pH value at any time!
c. Add the three-proof finishing agent
d. Then use the remaining water to fill the tank or the feeding bucket to the required amount.
e. Check the pH value again. If necessary, readjust with citric acid
f. During the entire preparation process, please stir the solvent according to the suggestion in point 3
2. Fabric preparation
5. In order to achieve the desired effect, the fabrics used for post-finishing must be free of all finishing aids, such as wetting agents, coloring aids, slurry residues, softeners and other surfactants.
6. In order to avoid reducing the effect, some mechanical finishing such as: rolling, electric finishing, brushing, etc. can be done after drying and before baking; steaming and steaming finishing can be done after baking. Improve the effect of post-finishing; napping and sanding should be carried out before post-finishing
7. If foam appears in the tie-dye solution, it may be a sign of the impurities mentioned in point 5. This foam may cause spots to appear on the fabric.
8. When processing fabrics, you must check for alkaline residues. Alkaline residues on the fabric will make the pH value alkaline, destroy the emulsion, and cause white spots to appear on the fabric.
9. If the conditions mentioned in points 5, 6, 7, and 8 occur, use a continuous or jet cleaning machine to re-wash the fabric with clean water in a slightly acidic pH value (4.5).
3. During the processing
10. Confirm that the fabric has been completely cooled before entering the tie-dye solution. High-temperature fabric will cause the temperature of the solvent to gradually increase, which may cause the emulsion to be destroyed.
11. If the tie-dye has been left for too long, check whether there is any stratification in the solution. Follow the instructions in point 3 and stir the solution continuously.
12. After preparing a small amount of tie-dye solution, you should not stop stirring the solution for a long time, and ensure that the solution can be quickly replaced and replenished.
