Carboxymethyl Starch & Guar Slurry for Printing Thickeners

Different types of printing thickeners such as guar slurry, carboxymethyl starch, etc. imparts plasticity and stickiness to the textile print paste, so that they can be easily applied on the surface without spreading and bleeding. They possess the capability of maintaining the design out lines.

They are traditionally made by weighing out and at times, if required dissolving the auxiliary chemicals and colorants. They are then stirred into the required weight of pre-prepared thickener. These printing thickeners are basically viscous and colorless paste made by using one or more thickening agents. The use of different terms such as thin, thickener, long or short is used to describe print pastes as more descriptive rather than scientific.

It is very important for thickeners to be compatible and stable with dyeing auxiliaries and dyes to be used with. Printing thickeners are widely appreciated for purity, effectiveness and longer shelf life. The produced derivatives of different textile printing thickeners is mainly based on tamarind, corn starch, tapioca, guar gum, etc, for various types of fabrics, dyes & textile printing applications.

Thickeners for textile printing are basically adhesive substances useful in making viscose printing pastes in water. They can be classified into: - natural, modified starch, emulsion and synthetic.

Carboxymethyl Starch
It is basically a guar gum derivative and is used as a mobility control agent like water loss control, oil, petroleum industries, friction reducing viscosity control & gas.

Guar Slurry
It has very distinctive property, which makes it appropriate for oil and well drilling. Its properties of water loss control and viscosity makes it suitable as an ideal thickening, suspending and stabilizer agent. It is mainly used for oil drilling processes that includes mud drilling, stimulation and fracturing.
