PROCESSING DEPARTMENT & IT'S OVERVIEW

Complete Guide to Fabric Processing Department After Weaving

Definition

Fabric processing refers to the treatment given to woven or knitted greige fabric to enhance its appearance, texture, performance, and aesthetic value. It is the second major stage after weaving or knitting in textile manufacturing.

Purpose

The goal of the processing department is to clean the fabric, remove impurities, add colors or finishes, and improve its usability, appearance, and comfort for the end-user. It transforms rough fabric into a refined, market-ready product.

Characteristics

- Enhances fabric aesthetics
- Improves fabric properties like softness, strength, absorbency
- Makes fabric suitable for dyeing, printing, and finishing
- Uses both mechanical and chemical treatments
- Can be batch or continuous process based on production

Full Process Flow

The processing department typically follows this flow:

Desizing → Scouring → Bleaching → Mercerizing → Dyeing → Printing → Finishing → Inspection → Packing

Detailed Process Steps

Desizing: Removes size materials from warp yarns.
Scouring: Removes natural waxes, oils, and impurities.
Bleaching: Whitens the fabric using oxidizing agents.
Mercerizing: Enhances luster, strength, and dye absorption.
Dyeing: Adds color using various dyeing methods.
Printing: Applies patterns or designs on fabric.
Finishing: Final touch-ups like softening, water resistance, wrinkle-free, etc.
Inspection: Fabric is checked for defects and quality.
Packing: Final fabric is rolled, packed, and labeled for dispatch.

Uses

Processed fabrics are used in fashion, home textiles (curtains, bedsheets), medical textiles, automotive interiors, sportswear, industrial fabrics, and more. Processing enhances both function and appeal.

Examples

Examples include bleached cotton bedsheets, mercerized shirts, dyed denim jeans, digitally printed scarves, fire-retardant workwear, and water-repellent jackets.

Properties After Processing

- Improved softness and drape
- Better colorfastness and dye uniformity
- Added functional properties like water repellency, antibacterial, or flame resistance
- Enhanced appearance and feel (hand-feel)
- Controlled shrinkage and pilling resistance

Comparison: Greige Fabric vs Processed Fabric

Greige Fabric: Raw, unprocessed; contains sizing, oils, and dust; dull appearance.
Processed Fabric: Cleaned, brightened, dyed/printed, and finished; ready for end use.
Processing makes fabric marketable, durable, and user-friendly.
