THICKENER FOR TEXTILE PRINTING PH - 50 |
|
PRODUCT PROFILE PH - 50 is thickening agent
especially suitable for the Textile Industry extracted from the endosperm
of the seed of the guar plant (Cyamopsis Tetragonolobus) and modified. It
is fine yellow coloured powder with additives specially suitable for
continuous / random dyeing of carpets and for space printing of yarn.
ADVANTAGES PH-50 disperses easily without lumps at neutral or alkaline pH without the use of educator funnel or other auxiliary dissolving equipments. A stock slurry of PH-50 upto a concentration of 12% can be prepared easily which remains pourable at least for 1 hour. The viscosity potential for this grade is activated by addition of any available acidic material to drop the pH below 7. PH-50 hydrates rapidly at acidic pH to yield a high viscosity thickener. PH-50 thickener. provides following advantages.
PH-50 Special is compatible with most chemicals used in printing of formulations at acidic pH. However, reintroduction of alkaline conditions in print paste will cause gelling. PREPARATION OF STOCK PASTE PH -50 specially disperse easily in cold water at pH above 7. A stock paste can be prepared at concentration upto 24g./liter and usually 5-10min. are necessary to ensure full dispersion of the gum which can be added to the water as rapidly as desired, acidification can be done with Citric, Acetic, formic acid to drop the pH below 7.0.Usually 0.5 to 1.0 g/l of acid is sufficient. When the pH is reduced to below 7 a colour change may be needed. Stock thickener should be stored in a cool, clean environment. USE PH -50 can be used in Continuous Dyeing , Random Dyeing and Printing of tufted carpet using Acid, permetallized Acid, Dispersed, direct, Basic & Nickel Chelating dispersed colours. STABILITY DRY- 6 months minimum when stored in a cool dry place. SOLUTION - 96 hours minimum,(1% at 25°C uncontaminated) PACKING 25kg Multiwall paper bags with polythene bag inside. |
