Exhaust application
0.3-1% Nylofix-993-CA
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 : 9 months from the date of manufacturing, if stored under controlled conditions.
