The Modification of Ramie Fibers by Alkali Treatment and Epoxy Crossing Linking

The ramie fabric’s stiff,rough and itching characteristics,which are caused by high strength and modulus of ramie fibers,have seriously affected the performance of ramie fabrics.To improve the softness of the fabric,the paper use a compound modified method that combined with alkali treatment and the epoxy cross linking.The paper discussed the impact of epoxy crossing linking fluid’s concentration and temperature on ramie fabric’s grafting rate crease recovery performance and tensile property.The experimental result indicated that,When the crossing linking fluid’s concentration is 5%～7%,temperature is 130～140℃,the grafting rate is bigger,and the crease recovery performance and tensile property of ramie fabric have been greatly improved,moreover.The ramie fiber s rigid fracture was improved into ductile fracture.
