Effect of TEMPO Oxidation on the Physical Properties of Ramie Fabrics

Ramie fabrics are often used for apparel, especially summer clothing. They have many interesting characteristics, such as durable properties for heavy use and cool contact feelings. In this study, we focused on the improvement of hard handling and poor resiliency of ramie fabrics. We modified ramie fabrics by light TEMPO oxidation and examined the effect of the oxidation on their texture. By TEMPO oxidation, a few carboxyl groups may be introduced to thesurfaceoframiefibers.Thedegree of introduction was about one seventh of the case of the preparation of cellulose nanofibers by TEMPO oxidation[1] . TEMPO oxidation of ramie fabrics gave low bending stiffness and good drape properties, and as the result, ramie fabrics showed softer handlings and better flexibility.
