Application Methods for Sulphur Black BR 200%

When using Sulphur Black BR 200%, it is important to follow proper application methods to achieve the best results. Typically, the dyeing process involves:

• Preparation: Begin by preparing the fabric to remove any impurities that may affect dye absorption.

• Dyeing: Immerse the prepared fabric in the dye solution and agitate gently. Maintain an appropriate temperature to ensure even dye uptake.
• After-treatment: After dyeing, rinse the fabric thoroughly, then fix the dye with an oxidizing agent to ensure the color is permanent.

For best outcomes, conducting small test batches to determine the optimal dye concentration and processing parameters is advisable. This approach helps in achieving consistent results and prevents wastage.
