Nylofix-993 CA | Acid Stable Polyamide Dye Fixing Agent
Nylofix-993-CA is a dyefixing agent for dyed and printed polyamide. After treatment with Nylofix-993-CA improves wet fastness properties. Nylofix-993-CA is stable to wide range acidic pH.

|Improves the wet fastness properties
||Prevents cross-staining during washing
|Has no effect on shade or light fastness of dyeings
||Recipe adjustment not require.
||Can be used on soft flow machines
||Light brown/brown-buff powder
|pH of 1% solution||8 +/- 1
|Miscibility||Soluble in water
||Compatible with anionic and nonionic products

pH 4-5, temp.70 - 80 deg.C, treatment time 15-20 min.
The handle of the fabrics may change slightly (becoming firmer, fuller), depending on the amount of Nylofix-993-CA used, the fabric construction, and the temperature during drying or post-setting.
The effects obtained by after treating with Nylofix-993-CA are stable to dry heat at the usual setting temperatures, but can be impaired by intense pressure steaming. Increasing the amount of Nylofix-993-CA will often improve the stability of the dyefixation to steaming. Stripping polyamide material treated with Nylofix-993-CA is difficult to re-dye or over-dye. Nylofix-993-CA should therefore be stripped first before redyeing.
For correction of any dyed shade of material aftertreated with Nylofix-993-CA first stripped Nylofix-993-CA by treatment with 0.5 - 1% Sarakol-DTI, pH 5.5, temp. 95 deg.C, treatment time 45-60 mins followed by rinsing. Once Nylofix-993-CA is removed from the substrate, then only stripping of dyestuff or redyeing/ overdyeing can be carried out. The shade after correction can again be fixed with Nylofix-993-CA as per standard procedure.
Instructions For Dilution
Procedure to prepare 35% Nylofix-993-CA
Preservation : It is recommended to add 0.1% Bronopol (2-Bromo,2-nitropropane, 1,3-diol) or Methyl Paraben (methyl para hydroxy benzoate) as an antimicrobial agent to avoid fungal/microbial growth
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.
