Sarafix-NEW is a novel acid stable dyefixing agent for acid and metal complex dyed/printed polyamide and their blends. After treatment with Sarafix-NEW improves wet fastness properties. Sarafix-NEW is stable to concentrated acid. Sarafix-NEW treated fabric does not stain white grounds of prints on polyamide therefore it is also suitable for light and pastel shades. Sarafix-NEW acts as a leveling agent for Nylon/wool blend for achieving solid even dyeing. It also acts as a reserving agent for Nylon/cotton blend fabrics. Sarafix-NEW is stable under acidic condition thus can be used for various application.

* Sarafix-NEW on prolong storage due to change in temperature, becomes darker.
* Sarafix-NEW has a tendency to crystallize at lower temperature. Heating upto about 45 deg.C and slight stirring should re-dissolve the crystals and product can be used.
The handle of the fabrics may change slightly (becoming firmer, fuller), depending on the amount of Sarafix-NEW used, the fabric construction and the temperature during drying or post-setting.
The effects obtained by after-treatment with Sarafix-NEW are stable to dry heat at the usual setting temperatures but can be impaired by intense pressure steaming. Increasing the amount of Sarafix-NEW will often improve the stability of the dyefixation to steaming. Polyamide material treated with Sarafix-NEW is difficult to re-dye or over-dye. Sarafix-NEW should therefore be stripped first before redyeing.
For correction of any shade of material treated with Sarafix-NEW, first strip Sarafix-NEW by treatment with 1 g/l Supergen-MX and 3 g/l Sodium carbonate, temp. 95 deg.C for 45-60 mins followed by rinsing. Once Sarafix-NEW 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 Sarafix-NEW as per standard procedure.
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.
