The process to remove the binding substances, such as pectin and lignin from the fiber bundle to release the individual fibers and increase the fiber strength is called retting process.
Retting process can involve water treatment, dew-retted treatment (10-13), and enzyme treatment (14-20).
21) proposed that composite properties can increase with the retting degree by better interface due to the reduction of non-cellulose portions left on fiber surface, and also by the higher fiber aspect ratio due to the extent of the separation of elementary fibers (22), (23).
