Coloured Cotton
Coloured cotton refers to natural pigmented cotton fibers that grow in different shades such as brown, green, red, blue, or beige rather than usual White cotton. Unlike conventionally grown white cotton, which must be dyed to achieve colour,coloured cotton gets its hue from natural genetic variations in the cotton plant.
Characteristics of coloured cotton:
Natural pigmentation.
Environmental benefits.
Soft Ness & Texture.
Colour range.
Genetic origin.
Scientific Background:
The pigments that creates colour in cotton are namely “flavonoids" (for browns) and quinones or tannins (for green)
Bleeding programs and biotechnological advances are improving the fiber length, yield, and brightness of coloured cotton varieties.
Transagenic techniques are being explored to introduce stronger pigmentation genes into commercial cotton.
Environmental and Industrial Significance:
Eco-friendly: Avoids toxic dyes and large water consumption during textile processing.
Sustainable fashion: Increasingly used in eco-textile industries and organic apparel brands.
Challenges: Lower yield, limited colour range and fading under UV exposure have restricted it's industrial scale adoption.
