Thickening Agent: Guar gum's primary role is to create a viscous solution. It is highly efficient, needing only small quantities to achieve a much higher thickness than other agents like cornstarch. This property is crucial for controlling the flow and consistency of chemical mixtures.
High Viscosity: It can form a thick, colloidal dispersion even in cold water.
Pseudoplasticity: Also known as shear-thinning, this property means the gum's viscosity decreases when stirred or applied and then recovers, allowing for smooth application and sharp patterns.
Stabilizer and Film-Former: It prevents the separation of ingredients in a mixture and forms a protective, flexible film on fabrics.
Water Retention: It helps to keep a mixture from drying out too quickly, ensuring uniform application and deep penetration of chemicals.
Biodegradable: As a natural product, it is environmentally friendly and non-toxic.
Textile Printing: Guar gum is used as a thickener in printing pastes. This ensures that the dyes stay in place on the fabric, producing sharp, vibrant, and well-defined patterns without bleeding.
Textile Sizing: It coats the yarn before weaving, acting as a sizing agent. This protective film reduces friction and prevents the yarn from breaking, improving weaving efficiency and the final fabric quality.
Finishing: It can be used in textile finishing processes to improve the fabric's feel ("hand"), add a protective film to enhance durability, and even improve its resistance to stains and wrinkles.
