When light falls on the fiber, part of light is reflected. The luster of a single fiber is determined by the total visual appearance of these reflections from the fiber surface. It is directly proportional to the amount of light reflected by a fiber. Silk fibers has a high luster and cotton has low luster.
Optical properties of fibre
Birefringence | Fiber Birefringence
The difference between the refractive index indices of the fiber in a direction at parallel to the fiber axis and in a direction at right angles to the fiber axis is called birefringence of that fiber. Birefringence is responsible for the phenomenon of double reflection.

The transmission, reflection and absorption of light determine the […]
