🧪 PRETREATMENT (SCOURING, BLEACHING) – TECHNICAL OVERVIEW 

🔍 What Is Pretreatment (Scouring)?

Pretreatment is a chemical cleaning and activation process applied to textile substrates before dyeing or printing. It removes natural and synthetic impurities from the fiber surface.

🎯 Purpose of Pretreatment

  • 🧼 To clean and hydrate the fiber

  • 🎨 To ensure uniform dye penetration and color consistency

  • 📉 To reduce defects and reprocessing rates

  • 🧵 To improve fastness properties

  • 🌱 To minimize chemical and dye consumption

🧪 Chemical Types Used in Pretreatment and Their Functions

Chemical Group Properties and Functions
Wetting Agents Reduce surface tension, allowing water to penetrate fabric quickly and evenly
Oil Removers Dissolve and emulsify oils and machine residues
Sequestering Agents Bind metal ions (Ca²⁺, Mg²⁺, Fe³⁺) to prevent shade variation and catalytic damage
Stabilizers Regulate oxidant activity (e.g., hydrogen peroxide), enhancing bleaching efficiency
Anti-Crease Agents Prevent mechanical damage during processing, especially in jet dyeing machines
Soaping Agents Remove unfixed dyes and chemical residues post-dyeing, improving fastness
