  • Publication number: 20180216254
    Abstract: A method to form yarn via film fiberizing spinning belongs to a textile technical field. A film cutting device is arranged behind each drafting system on a ring frame, whose cut resistance apron and cutting roller engage with each other to form a cutting zone to cut and fiberize the film to get belt-like multi-filaments. Then the multi-filament formed passes through the first, second and third drafting zones in sequence for drawing, in such a manner that the multi-filament molecular orientation and crystallization are improved. After being drafted, the multi-filaments are twisted into yarn by ring spinning, which provides a novel high-efficient and short-processing way of producing yarns of nano-micro fibers using films instead of conventional nano-spun fibers such as electro- and centrifugal spun fibers, thereby breaking restriction of “low bulk and low-speed production of nano-spun fibers” and integrating the film industry with the textile industry.
