RUBFAST-467 | Wet Rubbing Fastness Improver

Rubfast-467 is a speciality finishing agent to improve dry and wet rub fastness of all types of dyed and printed cotton and their blends. Rubfast-467 is compatible with certain cationic and nonionic silicone finishing agents. Rubfast-467 can be applied by both dry-on-wet and wet-on-wet application.

Padding method :

Preparation of padding bath with Rubfast-467

-Take 0.3-0.6 g/l acetic acid

-To this add required quantity of Rubfast-467 (30 g/l) and mix it uniformly.

-Make the total volume with water (pH 5.8-6.2)

-Mix well to get uniform solution

-Solution of 30 g/l Rubfast-467 will appear slight hazy and turbid with pH 3.7-4.2

Pad -> Dry at 130-160 deg.C

Exhaust method - RUBFAST-467 in Garment:

Step wise procedure for preparing Rubfast-467 solution

-Take 0.3-0.6 g/l acetic acid

-To this add required quantity of Rubfast-467 (3-5% on weight of garment) and mix it uniformly

-Make the total volume with water (pH 5.8-6.2) mix it uniformly

-Mix well to get uniform solution

-Solution of 3-5% Rubfast-467 will appear slight hazy and turbid with pH 3.7-4.2

Exhaust process:

40deg.C, 20-30 min (with intermittent stirring) Dry --> Curing @ 150-160 deg.C, 2-3 min

Special Instructions:

-If the water pH>6.2, adjust it to pH 5.8-6.2 and then use.

-30 g/l Rubfast-467 will appear slight hazy and turbid.

-Avoid using hard water.

-Prepare the solution at room temperature (approx.30 deg.C)

-The prepared solution to be kept under constant stirring and to be used immediately.

-Do not keep Rubfast-467 stock solution standing.

-Ensure that the padding bath pH is 3.7-4.2 throughout the process.

-Fabric to be treated should be free from anionic components.

-Do not use Rubfast-467 in print paste.

-Pre-lab trials are recommended with other finishing agents.

-Absorbency of fabric should be instant. To improve absorbency of all over printed fabric (reactive/pigment), 0.2-0.5 g/l Celldet-R (wetting agent) is to be added in the finishing bath.

-pH of the fabric should be neutral.

1. Rubfast-467 when used alone gives best results
2. Rubfast-467 can be used alongwith softener (Caresoft-809) to get desired results. Pre-lab trial with other softener is required before proceeding for bulk usage.
3. Rubfast-467 can be used alongwith dye fixing agent but no softener should be added in the same bath.
4. Exhaust process is suitable only for Package dyeing and Garment drum m/c.
5. For garments, it is essential to cure at 150 deg.C afte exhaustion
6. Rubfast-467 has limited durability to washing
