As dextrins do not easily react with chemicals, they are specially suitable for application in the textile field. In textiles printing, they are used as thickeners. Free of grit and other impurities, which usually accompany lower grades of starch, they ensure that the copper rolls (used in printing) do not suffer from abrasion. In sizing, they are used with starch for increased adhesiveness. In finishing, they give desired feel and handle to the fabric.
White dextrin is manufactured by partially hydrolyzing starch, using of a catalyst. The dextrinisation chemically reduces the starch molecules into smaller components. White dextrin is white in colour but with reduced viscosities. it’s cold water solubility’s rang from 25% to 65% White dextrin produce;s a light colour ed paste that set to soft but a definite gel. The higher solubility white dextrin Can be used at much higher concentration to yield very soft gels. Its solution is a half –transparent plaster. White dextrin has good glutinosity and resolution. It as an indispensable excepiant for medicine food and health care industry. It is also used as an additive in the certain applications for the manufacture of Textile, Adhesive and Dye’s.
