Product Description

BWF-422 Cationic Color Fixing Agent

BWF-422 is a formaldehyde-free cationic polymer color fixing agent containing 50 ± 0.5% solids. It is designed for reactive and other anionic dye applications. Its 1% solution pH is 7.0-10.0, while the recommended fixation bath pH is 6.0-7.0.

Product overview

BWF-422 is supplied as a light yellow viscous liquid that dissolves readily in cold water. It is used after dyeing and thorough washing, with particular emphasis on reactive dye fixation. The grade combines a 50% nominal solid content with a 45-60 °C treatment range. For dyehouses comparing liquid fixing agents, BWF-422 offers a clearly defined combination of product concentration, solution pH and application conditions. These specifications support product selection; the final fastness and shade results still need to be established on the actual textile.

Key features

50 ± 0.5% solid content.

Cationic polymeric color fixing agent for reactive and other anionic dye systems.

Light yellow viscous liquid, readily soluble in cold water.

Recommended application at 0.5-2.0% o.w.f. and 45-60 °C.

Separate specifications for 1% solution pH and fixation bath pH.

Applications

Use BWF-422 for after-dyeing color fixation in reactive and other anionic dye systems. It is a candidate for lines that can operate at bath pH 6.0-7.0 and 45-60 °C. When comparing it with BWF-401, consider concentration, bath adjustment, handling and the measured result on the dyed fabric. A higher solid content alone does not establish which model will produce the required textile result.

Recommended application method

Application parameter

Recommended starting condition

Dosage

0.5-2.0% o.w.f.

Fixation bath temperature

45-60 °C

Treatment time

20-30 minutes

Fixation bath pH

6.0-7.0

O.w.f. means on the weight of fabric. For 100 kg of fabric, the published 0.5-2.0% range corresponds to 0.5-2.0 kg of fixing agent, before any dilution needed for application.

Complete the dyeing stage and rinse thoroughly with clean water.

Carry out soaping and another rinse when required by the dyeing process.

Prepare the fixation bath and measure its pH after bath preparation.

Apply BWF-422 within the trial dosage range and treat at 45-60 °C for 20-30 minutes.

Rinse the treated fabric and continue with the intended finishing process.

Process control and compatibility

A 1% solution pH of 7.0-10.0 does not mean that the fabric should be fixed at that pH. Control the actual fixation bath at the recommended 6.0-7.0.

Rinsing before fixation is important for removing residual dye and process chemicals. Rinse after fixation to avoid interference with the next production step.

Check shade and fabric appearance during dosage optimization. Excessive dosage or unsuitable pH and temperature can cause color changes.

Packaging and storage

Standard net packaging: 50 kg, 210 kg or 1,100 kg in plastic containers as specified for the order.

Store in a dry, well-ventilated place away from direct sunlight. Stated shelf life: 6 months under the recommended storage conditions.

Frequently asked questions

What is the solid content of BWF-422?

The specified solid content is 50 ± 0.5%.

Is BWF-422 applied at pH 7.0-10.0?

The 7.0-10.0 value describes a 1% aqueous product solution. The recommended fixation bath pH is 6.0-7.0.

What temperature and time are recommended?

The published starting conditions are 45-60 °C for 20-30 minutes, using 0.5-2.0% o.w.f.

Can BWF-422 be substituted directly for BWF-401?

The two grades have different solid contents and product solution pH ranges. Evaluate bath adjustment and textile performance before changing the production recipe.

How should the final dosage be selected?

Test several dosages within the recommended range on the actual dyed textile. Compare the required fastness result together with shade and appearance, then confirm the selected treatment on a production trial.
