Length and Fineness of Jute Fiber Filaments at Various Stages of Yarn Production and in Yarns of Different Qualities of Fiber

Abstract

Changes in length and fineness of jute fiber filaments have been studied at different stages of yarn production, including carding, drawing, roving, and spinning. Length decreases and the filament becomes finer as processing progresses. The distribution of length and the length-fineness relation, however, remain similar in all stages. Fila ment length in yarns made by a standard process from different types of jute depends only slightly on fiber quality, w hile intrinsic filament fineness correlates fairly well with the filament fineness of unprocessed fiber.
