Q Why is sodium alginate used in printing?
A Sodium alginate sh is a seaweed derivative that is used to thicken dyes for painting, stamping or screen printing. For thicker fabrics, use a thinner consistency of liquid dye solution to ensure dye penetration.

Q What is alginate in textile?
A In textile printing, alginates are used as thickeners for the paste containing the dye. Alginates became important thickeners with the advent of reactive dyes. These combine chemically with cellulose in the fabric.

Q What is the most commonly used binder?
A Common traditional binders include sucrose, gelatin and starch. More recently introduced binders include polymers such as cellulose derivatives and polyvinylpyrrolidone, which have improved adhesive properties. Examples of dry binders include cross-linked polyvinylpyrrolidone and microcrystalline cellulose.

Q What is pigment binder and solvent?
A Pigments provide color and hide, while binders work to "bind" the pigment together and create the paint film. Solvents are the liquids that suspend the ingredients and allow you to place the paint on the surfaces, and additives are ingredients that provide specific paint properties such as mildew resistance.
