Substitute Alkali / Remove impurities and grease / Softening fibers / Cost savings / Environment protection

【Instruction】

【Product Features】

1. Promote controllable simultaneous dyeing, and its buffering effect is especially suitable for pH-sensitive dyes.
2. Even in small bath ratio dyeing processes, it can slow down the dyeing and fixation rate without affecting the color yield.
3. Low dosage can significantly reduce the burden of wastewater treatment.

【Usage Method】

• Suggested dosage: Determine the optimal dosage based on dyeing depth, dye type, bath ratio, etc. through sample testing. Generally, it is 1/5 of the amount of soda ash.
• Reference process: Dye: x% o.w.f; Leveling agent: 0.5g/L; Sodium sulfate: 20 - 30g/L; Substitute alkali: 5g/L.
• Dye dissolution: Accurately weigh the specified amount, dilute it with 10 times the amount of water in a secondary tank, and then add it to the dyeing tank.
• Feeding: Add 1/3 of the amount slowly at the beginning, and then add the remaining 2/3 at once.
• Dosage: 1/5 of the amount of soda ash.
• Immersion dyeing: For bath ratio > 10, calculate the amount based on water ratio; for bath ratio < 10, calculate the amount based on fabric weight.
  60°C × 40 - 60min dyeing → water washing → neutralization → hot water washing → soaping.
• Note: The color shade of the fabric dyed with substitute alkali is slightly different from that of soda ash. Please first make a small sample in the laboratory to find the optimal dosage of substitute alkali, and then adjust the dye to find the formula for the desired color shade before production.

【Precautions】

1. Conduct a small sample test in advance to determine the optimal dosage.
2. If used in the same bath with other finishing agents, please conduct a compatibility test in advance.

【Storage and Packaging】

1. Store in a cool, dry, and well-ventilated place, protected from sunlight and rain. The shelf life is 6 months.
2. Polyethylene plastic woven bag with an inner plastic bag, 25KG per bag.
