De-sizing;

CHIMISTONE NILF is compatible with all the usual de-sizing agents. It is therefore well suited as a wetting agent in the de-sizing bath where the goods normally entered in a dry state.

For continuous method; 
1-3 g/l CHIMISTONE NILF 
For exhaustion (overflow, Jig or winch); 
0.5-2.0 g/l CHIMISTONE NILF  

Scouring and Boiling off cotton;

Piece goods or yarn on the jig, package machine etc .

CHIMISTONE NILF effect immediate wetting of the goods with the alkaline
Liquor and accelerates the boiling off process, fats, waxes and other
Impurities are suspended in, and easily remove by the subsequent
Rinses, Boiled off with CHIMISTONE NILF , are clean and extremely absorbent.

Recommended addition;

0.2-0.4 % CHIMISTONE NILF calculated on the weight of material.

EXHAUSTION PROCESS :

Grey Cotton Scouring and Bleaching

A: Recipe for Scouring in Jigger etc.

2-4 g/l CHIMISTONE NILF

0.5-2 g/l Chimical 540

15-20cc/l Caustic soda 48ºBé

0.5-1.5 cc/l Hydrogen peroxide 200 vol.

The bath is prepared at 50 ° c and heated to 98 ° C over 60-90 minutes.

B: Recipe for Bleaching in Jigger etc.

2- 4 g/l CHIMISTONE NILF

1-2 cc/l Chimistab FG

0.5 g/l Chimical 540

4-6 cc/l Caustic soda 48ºBé

8-12cc/l Hydrogen peroxide 200 vol.

The bath is prepared at 50 ° c and heated to 98 ° C over 30-60 minutes

C: Recipe for Bleaching in Winches/Jet Machine etc.

0.5-1.5 g/l CHIMISTONE NILF

0.5-1cc/l Chimistab FG

0.5-2cc/l Chimical 540

1.5-2.5gm/l Caustic soda

3.5-5 cc/l Hydrogen peroxide 200 vol.

The bath is prepared at 50 ° c and heated to 98 ° C over 30-60 minutes or to 110 ° C over 15-20 minutes

D: Washing off Reactive Dyeings and Prints on Cellulosic fibres and their blends.

Soaping of Dyeings : 0.5-2.0 g/l CHIMISTONE NILF (In exhaust or continuous method)

Soaping of Prints ; 0.5-1.0 g/l CHIMISTONE NILF

Hard water hinders soaping of dyeings and prints produced with reactive dyes. Best result obtained by preventing re-deposition and removing hydrolised reactive dyestuff adding 0.5 g/l Chimisperse FA (Dispersing and Sequestering agent)

Along with CHIMISTONE NILF

E: Synthetic Fibre Degreasing :

1 – 2 gr./l. CHIMISTONE NILF 2 – 3 gr./l. Soda Ash

0,5 gr./l. Chimisperse FA (Dispersing and Sequestering agent)

Detergent / Wetting agent specially indicate for scouring and bleaching cotton and it's blends in semi-continuous and continuous processes. It's special excellent properties of stability in strong alkaline bath.

•  Bleaching by Cold Pad Batch, even with high concentrations of Caustic Soda.

•  Cellulose and it's blends scouring in Pad-Steam Process.

•  Cellulose and it's blends bleaching In Pad-Steam.

•  It is also adequate for Jigger processes.
