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.

2. Dye the Catfix-511 (N) treated the fabric with pigment at 60 deg.C for 30 mins. and Drain
3. After pigment dyeing, treat the fabric at 50 deg.C with a binder for 20 mins.
[Take binder as per depth of shade]
Precautionary measures
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 : 12 months from the date of manufacturing, if stored under controlled conditions.
