Pretreatment Chemicals are used to convert raw fiber/yarn/fabric into substrates suitable for dyeing, printing and finishing. These fibers/yarns/fabrics could be of cotton, wool, silk, synthetics and blends of these. The pretreatment processes include: Desizing (Removal of size), Scouring/wetting (removal of oils, waxes, dirt etc. thus imparting absorbency), Bleaching (removal of natural colouring matter) and Mercerizing (increasing dye ability, lustre and strength).
