What Is Greige Fabric?
Greige fabric is unfinished textile material straight from weaving, before scouring, bleaching, or dyeing.
Its natural beige tone may come with weaving size, fiber impurities, oils, waxes, and cotton seed fragments.
Why pretreatment matters: Scouring and bleaching help create a cleaner, more absorbent fabric base for consistent dyeing and printing.
01. Desizing: Removing Yarn Size
Why it matters: Desizing removes the protective sizing applied to warp yarns during weaving. The original material cites a typical removal target above 80%.
How it works: Fabric is treated with a desizing agent or warm water to loosen and remove the size.
Common approaches: Enzymatic, alkaline, and oxidative desizing.
02. Scouring (Boiling-Off)
- Scouring uses chemical and physical action to remove impurities from textile fibers.
The goal: Remove oils, waxes, pectins, and other residues from cotton, wool, linen, silk, and synthetic fabrics to improve absorbency. - In practice: Scouring agents, including alkaline formulations, help emulsify oils and wash away unwanted substances.
- Before scouring: Desizing is often carried out first to remove yarn-size residues.
03. Bleaching: A Clean Base
- The purpose: Bleaching reduces residual natural pigments and yellowish tones left after scouring, producing a brighter fabric base.
- Why it matters: A uniform base helps achieve more reliable results in printing and light-shade dyeing.
- Common method: Hydrogen peroxide is widely used for textile bleaching. Conditions must match the fiber type to avoid damage.
