CATFIX-511 | Cationizing agent

Product Information

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

Key Features & Benefits

Key Features Benefits
Low molecular weight product Uniform depostion of Catfix-511
High cationic charge density product - High exhaustion rate
- Performance of 1% Catfix-511 is better than conventional product
Wide pH range Applicable at pH 5-10
Very good affinity for pigment Less bleeding of pigment during subsequent softening /biopolishing process
One step process for lighter shades - No/less quantity of binder require
- Saving in energy and time
Formaldehyde free Suitable for Oekotex and baby wear

General Characteristics

The fabric to be cationzed should be free from anionic impurities (*see below)

* Process sequence

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

Pigment depth Catfix-511 to be taken:

Pigment Catfix-511 to be taken
4% 1-1.5%
4-6% 1.5-2.0%
6-9% 2-2.5%

2. Dye the Catfix-511 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 8 months from the date of manufacturing, if stored under controlled conditions.
