Corn fiber is a polymeric fiber made from corn as the raw material. Wide applications have been found for corn fibers in recent years and many progresses on the study of corn fibers have been made as well. The performance of corn fiber is determined by the molecular weight of polylactic acid. Corn fibers have some professional properties, such as high transparency, well-heat-resistant stability, well-coloring, and full biodegradability, as well as the feature in ecological recycle. These means the corn fibers are new-typical and green, full-environmental fibers. The corn fibers can be blended with other fibrin fibers with good hygroscopic to get products of high-performance and low in price. The blending techniques of corn fibers with color cotton fibers and corn fibers with Richcel and lambsdown are studied and developed in this paper and good social and economical benefits have been achieved.
