STAGE // 01

Pretreatment

The preparation stage that removes impurities, controls absorbency, and establishes a clean, stable fabric surface before dyeing.

PROCESS FLOW

01Grey Fabric

02Desizing

03Scouring / Washing

04Bleaching / Mercerizing

05Neutralisation

06Ready for Dyeing

Engineering Purpose

Remove sizing agents, oils, waxes, dirt and processing residues from greige fabric.
Improve wettability and uniform liquor penetration before dyeing.
Control fabric width, tension, shrinkage and surface condition where required.
Deliver a consistent, clean substrate so downstream shade and quality targets are repeatable.

Key Parameters

Working WidthTypical open-width lines: 1200–3600 mm

Process ControlTemperature, pH, liquor flow, tension and speed

Fabric TypesWoven and knitted fabrics according to machine configuration

Key ObjectiveUniform absorbency and reproducible preparation
