Abstract

ABSTRACTCellulose acetate may be dissolved and mixed with a lignin derivative in acetone in order to form a modified cellulose acetate. The modified product of cellulose acetate is then spun to form a modified cellulose acetate fiber. A mixed fiber mat can be prepared by blending the modified cellulose acetate fiber with natural cellulose fibers and then softening the mixture. Thereafter, the mixed fiber mat can be heated and pressed to form a fiber laminate board that is, e.g., suitable for use as trim materials for automobiles.
