Product Overview
The Dhara Desizing Machine is engineered for the efficient and uniform removal of sizing materials applied during weaving, such as starch, gums, PVA, and synthetic size compounds. Designed to support modern wet-processing lines, the system ensures thorough size removal, consistent liquor penetration, and fabric-safe handling across a wide range of fabric constructions.
By enabling controlled enzymatic hydrolysis, the Dhara Desizing Machine prepares fabric for downstream processes such as scouring, bleaching, dyeing, and finishing, while minimizing chemical consumption and processing variability.
Process Principle
Desizing is achieved by enzymatic hydrolysis, where starch-based sizes are converted into water-soluble fragments under precisely controlled temperature, concentration, and dwell time.
The Dhara system allows desizing operations to be carried out from ambient temperature up to boiling temperature, depending on enzyme formulation and fabric requirements.
