Product Description

BWF-658 Color Fixing Agent for Reactive Dyed and Printed Textiles

BWF-658 is a formaldehyde-free cationic polymer color fixing agent for reactive-dyed blended textiles and printed fabrics. It contains 50 ± 0.5% solids and is intended for applications requiring improved resistance to washing, perspiration and high-temperature soaking.

Product overview

BWF-658 is a reddish-brown to amber transparent viscous liquid that dissolves readily in cold water. The product is intended for reactive dye shades including bright red, rose red, jujube red, brilliant blue and black on blended textiles, as well as printed fabrics. Its application guidance covers both exhaust treatment and padding, allowing the dyehouse to select the method that matches the production line. The finished-textile result must be confirmed on the actual shade and substrate using the required test conditions.

Key features

Designed for reactive-dyed blended textiles and printed fabrics.

Intended to improve fixation where washing, perspiration or high-temperature soaking resistance is required.

50 ± 0.5% solids and a specified 1% solution pH of 3.0-6.0.

Exhaust treatment range: 0.5-2.0% o.w.f. at 50-70 °C for 20-30 minutes.

Padding concentration: 5-20 g/L.

Can be evaluated with nonionic softeners during post-finishing.

Applications

Evaluate BWF-658 for reactive-dyed blended textiles, printed fabrics and shades that need additional color fixation before delivery or further finishing. The named shade examples describe its intended application scope; they do not imply equal performance for every dye recipe. It can also be evaluated in a post-finishing process that uses a nonionic softener, subject to compatibility and textile testing.

Recommended application method

Recommended starting condition

Dosage

0.5-2.0% o.w.f.

Fixation bath temperature

50-70 °C

Treatment time

20-30 minutes

O.w.f. means on the weight of fabric. The stated range corresponds to 0.5-2.0 kg of fixing agent per 100 kg of fabric. Establish the bath pH and the final recipe for the actual textile through trials.

Padding application

The recommended padding concentration is 5-20 g/L. Set wet pickup and subsequent processing conditions for the actual fabric and equipment through trials. A padding concentration in g/L is not directly interchangeable with an exhaust dosage in % o.w.f.

Preparation and treatment sequence

Thoroughly clean the dyed or printed textile before fixation to remove residual color and process chemicals.

Select exhaust treatment or padding according to the production line.

Run a sample trial within the relevant starting range.

Check the required fastness result, shade and fabric appearance before confirming production conditions.

Process control and compatibility

The technical data sheet allows combination with nonionic softeners during post-finishing. Confirm the compatibility of the actual commercial formulations and check the treated fabric before combined production use.

Use thorough washing before fixation. The degree of residual dye can affect the treatment result and the apparent benefit of the fixing agent.

Washing resistance, perspiration resistance and high-temperature soaking resistance are separate evaluation criteria. State the required test method and acceptance level for each relevant property.

Packaging and storage

Standard net packaging: 200 kg plastic drums or 1,100 kg IBC tanks.

Store in a dry, well-ventilated place protected from direct sunlight. Stated shelf life: 12 months under the recommended storage conditions.
