Guar TEXTILE Derivative FOR TEXTILE Industry
Guar gum and guar gum derivates are used in to major textile applications: as a printing thickener and as a binder in the sizing of yarns, particularly for denim sizing. In the textile printing industry, guar gum is used as a printing thickener to keep the dyestuff from spreading on the fabric (add photo of rotary printing machine).
In denim sizing, guar gum is used to bind the starch and stabilize the viscosity in the sizing agent. In this application, it has replaced acrylic polymers which are banned in many countries for use in textile products as they are considered carcinogens. The guar gum is used on a 2% basis by weight of starch (add photo of sizing Machine).

Preparation of gum paste
Natural Textile Gum is made in solution consistency in water at room temperature under high speed stirrer . for 15-20 minutes so that the solution is ready after it cools. After 2 Haours added Acid to mantain the PH for printing .then add dyes and ready to print.
25 Kg. laminated paper bags with PE lining inside.
Sealed bag under normal condition for 6 months.
Guar Gum should be stored in cool and dry place, away from direct sun light.
