Mercerization is a process where
cotton or yarn is treated with 1-2% caustic soda solution at temperature of
20-30ºC. It is necessary to hold the fabric under tension and wash thoroughly.
Benefits obtained by
Mercerization/Objectives:
- Increase tensile strength.
- Improved hygroscopicity.
- Improved smoothness.
- Improved luster.
- Improved dimensional stability.
- 20-30% dye and chemical same while dyeing after mercerization.
Effect of mercerizing condition:
- Concentration of caustic soda solution.
- Temperature (15-25ºC).
- Tension.
- Time.
- Wash thoroughly.
- Wetting agents (0.5-1.0gm/l).
The effect of mercerized cotton
depends on various factors:
- Cross-section of the fiber.
- Staple length of the fiber.
- Wall thickness of the fiber.
- Concentration of sodium hydroxide.
- Temperature of mercerization solution.
- Tension.
- Yarn construction.
- Yarn twist.
- Doubling of yarns.
- Degree of singeing.
- Application of tension.
- Rate of drying etc.
