Product Description

BWF-303 Formaldehyde-Free Color Fixing Agent

BWF-303 is a formaldehyde-free cationic polymer color fixing agent for textile aftertreatment. It contains 50 ± 0.5% solids and is suitable for reactive, direct, sulphur, indigo and other anionic dye systems, with a recommended fixation temperature of 20-40 °C.

Product overview

BWF-303 is used after dyeing and washing to improve color fixation, particularly in reactive dye applications. The product is a light yellow to reddish-brown viscous liquid that dissolves readily in cold water. Its 20-40 °C application range makes it a candidate for processes that carry out fixation at a lower bath temperature. The final treatment recipe should be established using the actual dyed fabric, because dye selection, residual unfixed color, pH and dosage can all affect the result.

Key features

Formaldehyde-free color fixing agent described in the product technical data sheet.

Cationic polymeric compound for textile color fixation.

50 ± 0.5% solids in a liquid product that dissolves readily in cold water.

Suitable for several anionic dye classes, with particular emphasis on reactive dyes.

Recommended fixation at 20-40 °C and bath pH 5.0-5.5.

Applications

Use BWF-303 in the fixation stage after dyeing with reactive, direct, sulphur, indigo or other anionic dyes. It is particularly relevant when a dyehouse needs to evaluate color fixation within a 20-40 °C treatment window. Confirm suitability for the particular fiber composition, dye formulation and required fastness test before production use.

Recommended starting condition

Dosage

Fixation bath temperature

Treatment time

20-30 minutes

Fixation bath pH

5.0-5.5

O.w.f. means on the weight of fabric. For example, 1.0-3.0% o.w.f. corresponds to 1-3 kg of fixing agent per 100 kg of fabric. Dilution and the production recipe should be confirmed during trials.

Complete dyeing and rinse the fabric thoroughly to remove residual dyestuff and chemicals.

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

Prepare the fixation bath and control it within the stated pH and temperature ranges.

Add BWF-303 at the selected trial dosage and treat for 20-30 minutes.

Rinse with clean water before subsequent finishing.

Typical sequence: dyeing → rinsing → soaping and rinsing when required → fixation → rinsing → subsequent finishing.

Process control and compatibility

The pH of a 1% product solution is a quality-control property. The fixation bath has a separate recommended pH of 5.0-5.5. Check the actual bath rather than relying on the product pH.

Remove unfixed dye before fixation. Excess dosage or unsuitable treatment conditions can change the shade or fabric appearance, so evaluate the treated sample against an untreated control.

Prepare diluted solutions for prompt use and keep the equipment clean. If dilution must be stored beyond the day of preparation, consult Bluwat for water-quality and preservation guidance.

Packaging and storage

Standard net packaging: 50 kg, 210 kg or 1,100 kg in plastic drums or 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

Which dye types is BWF-303 suitable for?

BWF-303 is intended for reactive, direct, sulphur, indigo and other anionic dyes. Reactive dye fixation is a principal application identified in the technical data sheet.

What is the recommended dosage of BWF-303?

The starting range is 1.0-3.0% o.w.f. Select the final dose through trials using the actual shade and fabric.

Can BWF-303 be applied at 20-40 °C?

Yes. Its recommended fixation temperature is 20-40 °C, with a treatment time of 20-30 minutes and bath pH of 5.0-5.5.

Is BWF-303 formaldehyde-free?

The product is described as formaldehyde-free in the technical data sheet. If a buyer has a specific test method or finished-textile limit, state that requirement when requesting technical documentation.

Can BWF-303 guarantee a particular fastness grade?

A fixed fastness grade cannot be assigned to every dye and fabric combination. Test the treated textile under the required washing or other fastness method before approving a production recipe.
