Ramie

Description

General

Also known as Chinese Grass. Ramie is one of the strongest natural fibers and exhibits even greater strength when wet. It possesses little elasticity and is somewhat brittle and stiff. This causes fiber breakage and abrasion where creased or folded repeatedly. Like linen and cotton, Ramie has poor resiliency and wrinkles easily. Other properties include resistance to alkalies, rotting, light and mildew. Ramie is not harmed by mild acids but can be damaged by concentrated acids.
