The good degradation of natural fiber benefits environmental protection. So, people have spent more and more time on it. It is a new method of natural fibre development to study on chemical treatment of cotton-straw peel fiber . The development of cotton-straw peel fiber resources not only can recycle the waste, but increase fiber material resource as well. In this paper, the component of cotton-straw peel was tested according to the related standards. It was got that the cellulose content compared with other vegetable fiber`s component, the cotton-straw peel was lower, and the content of colloid, hemi-cellulose, water soluable and the gum grease of cotton-straw peel was higher than other vegetable fiber. The chemical degumming of Bast fiber was used as reference to investigation the chemical treatment of cotton-straw peel. The chemical treatments such as first boiling, second boiling and refining after second boling were studied. Through the sythentic evaluation of peel result, it was obtained that second boling method was regard as. The processing route was following as: sample→acid soak→washing→fir
