Xanthan Gum, a member of the natural thickener family, has grown in usefulness in food and industrial applications. However, when used as a thickener, Xanthan Gum showed more elastic behavior and weak gel characteristics due to its stiffness and ordered conformation, as well as printing defects like poor screen ability, low color yield, and uneven color. If modification techniques are used to alter the rheological characteristics of XG solutions in order to get effective printing results This work involved the deacetylation of several modified xanthan gums (MXG) using an alkali treatment at a certain temperature on cotton and silk fabrics and using it as a pretreatment of polyester fabrics. The screen ability, color yield, and penetration of printing were all enhanced when MXG was used as a thickener instead of xanthan gum. Excellent printing performances were achieved by These thickeners, which have might be good pastes to meet the requirements of cotton, silk and polyester printing
