Chemical Composition of Ramie || Mechanical Properties of Ramie Fiber

Ramie is one kind of natural fiber. It is the oldest textile fiber of plant origin. The demand of ramie fiber is increasing for its luster, strength, excellent microbial resistance and valuable hygienic properties. Ramie fiber is used for making bled with other fibers like cotton, wool, flax, polyester, acrylic and silk.

Chemical Composition of Ramie: Ramie fiber is degummed for making it usable as textile fiber. Ramie fiber is collected from the ramie plant. After analyzing, it is found that, ramie fiber is composed of following chemical composition. Following measurement is done in percentage.

Cellulose                              : 68.6 – 76.2%

Lignin                                    : 0.6 -0.7%

Hemi-cellulose                  : 13.1 – 16.7%

Pectin                                   : 1.9%

Wax                                       : 0.3%

Microfibrillar Angle          : 7.5°

Moisture Content            : 8.0%

Density                                 : 1.50g/cm3


Mechanical Properties of Ramie Fiber: As like chemical properties, ramie fiber consists of mechanical properties. They are-

Fiber Diameter                  : 0.034 mm

Fracture Load                    : 0.467 N

Tensile Strength               : 560 MPa

Fracture Stain                    : 0.025%

So, that’s all about chemical and mechanical properties of Ramie fiber.


One thought on “Chemical Composition of Ramie || Mechanical Properties of Ramie Fiber

  1. As ramie requires chemicals to degum the resins which hold the fibres together. Wouldn’t you see residues of the chemicals used in the chemical composition of ramie fibres and should therefore be included?
