ZOROFAST-FMD | Wet Rubbing Fastness Improver

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

Padding Method

Preparation of padding bath with Zorofast-FMD

• Take 0.3-0.6 g/l acetic acid
• To this, add required quantity of Zorofast-FMD (30 g/l) and mix it uniformly.
• Make the total volume with water (pH 5.8-6.2). Avoid using hard water. 
• Mix well to get uniform solution
• Solution of 30 g/l Zorofast-FMD will appear slight hazy and turbid with pH 3.7-4.2 

Pad -> Dry at 130-160 deg.C

Exhaust method - Zorofast-FMD in Garment: 

Step wise procedure for preparing Zorofast-FMD solution

• Take 0.3-0.6 g/l acetic acid
• To this add required quantity of Zorofast-FMD (3-5% on weight of garment) and mix it uniformly
• Make the total volume with water (pH 5.8-6.2) mix it uniformly. Avoid using hard water. 
• Mix well to get uniform solution
• Solution of 3-5% Zorofast-FMD 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 Zorofast-FMD will appear slight hazy and turbid.
• Avoid using hard water.
• Prepare the solution at room temperature (approx. 30deg.C)
• The prepared solution to be kept under constant stirring and to be used immediately. 
• Do not keep Zorofast-FMD stock solution standing.
• Ensure that the padding bath pH is 3.7-4.2 throughout the process. 
• pH of the fabric should be neutral. 
• Fabric to be treated should be free from anionic components. 
• Do not use Zorofast-FMD 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.

1. Zorofast-FMD when used alone gives best results
2. Zorofast-FMD can be used along with softener(Hydrosoft-142)to get desired results Pre-lab trial with other softener is required before proceeding for bulk usage.
3. Zorofast-FMD can be used along with 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 after exhaustion
6. Zorofast-FMD has limited durability to washing
