Solvron® Dissolving Method
Please note the following to save energy and improve the quality of the product.
1. Dissolution Temperature
- Depending on the type of Solvron® used, please heat up the treatment bath water to the desired temperature in advance before adding the material to be dissolved.
- During the dissolution process, please continue heating to maintain the temperature of the treatment bath water.
2. Dissolution Bath Ratio
- Please use a large amount of bath water to disperse the dissolved Solvron®.
(The suitable bath-ratio of water to Solvron® is 1:30 based on weight)
3. Dissolving Time
- The dissolving time differs depending on the usage conditions.
Ex.) It takes about 10-20 minutes if the Solvron® is in direct contact with the treatment bath water, and about 30-60 minutes depending on the extent of weaving and knitting.
4. Dissolution Facilitation
- It is easier for the material to dissolve, if it has less tension and the treatment bath is stirred sufficiently.
5. Rinsing
- After dissolving the Solvron®, rinse the material again in overflowing new warm water to completely remove the Solvron®.
(Note) If the Solvron® remains after the Solvron® dissolution process and is left to dry, it is extremely difficult to re-dissolve it.
6. Factors Affecting Dissolution
- When dry heat setting, the temperature for dissolving treatment may increase depending on the temperature.
- If tension is applied during dissolution, the temperature for dissolving treatment may increase.
- Solubility will decrease in the presence of formalin, heavy metals or other materials.
(Note) Dissolution may not always be possible, depending on the circumstances.
7. Wastewater Treatment
- The activated sludge method is effective in treating wastewater with Solvron®.
