CATFIX-511 (N)

CATFIX-511 (N) | Cationising agent for pigment dyeing

Product Information

Catfix-511 (N) is a special cationising agent developed to improve the exhaustion of pigment on cellulosic and cellulosic rich blends. Catfix-511 (N) can also be used for the fixation of indigo and sulphur dyes. It can also be used as pre-treatment auxiliary in pigment inkjet printing. Novel effects can be obtained on garments by localised application of Catfix-511 (N), as it has good affinity for anionic dyes.

* Process sequence

1. Treat substrate with below mentioned dosages of Catfix-511 (N) at 50 deg.C for 20 mins. 

Pigment depth
Catfix-511 (N) to be taken 

2. Dye the Catfix-511 (N)treated fabric with pigment at 60 deg.C for 30 mins. and Drain

3. After pigment dyeing, treat the fabric at 50 deg.C with binder for 20 mins.
[ Take binder as per depth of shade ]

Precautionary measures

Treat the fabric with cationic agent namely 0.5 g/l Fixanol(Conc). or 1 g/l Saradye-FN to achieve uniform or even dyeing.


Storage : Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg C. Close lids firmly to avoid contact with air and moisture.

Shelf Life : 9 months from the date of manufacturing, if stored under controlled conditions.
