摘要： A ring composite spinning method based on film filamentization is provided, which belongs to a textile technical field. According to the method, a film cutting drafting device is arranged above each drafting system on a ring spinning machine for cutting film material into ribbon-shaped multi-filaments to achieve the film filamentization, which changes a conventional formation of filament through linear spraying by spinneret orifices; then the multi-filaments formed pass through first and second filament drafting zones in sequence for drawing, so as to enhance and attenuate the multi-filaments. After in drawing, the multi-filaments are twisted with conventional staple fibers to form a composite yarn with high quality and functions, achieving one-step production of composite yarns of nano-micro fibers without online combination of nanofibers spinning and ring staple spinning, thereby breaking restriction of “low bulk and low-speed production of nano-spun fibers” and integrating film industry with textile industry.

摘要： 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.

摘要： A method for ring-spinning with pneumatic guiding and capturing includes steps of: respectively fixing a pneumatic guiding and capturing apparatus in front of each drawing system of a ring frame; twisting the ribbon-like strand outputted through a front roller nip to form a spinning strand, moving the spinning strand into a holder groove of a capturing holder; guiding ribbon-like strand edge fibers to closely contact with a spinning strand main body by negative pressure airflow in the holder groove; before the ribbon-like strand edge fibers enter an in-take opening, cohering the edge fibers with the spinning strand for being partly captured by the spinning strand stem; other un-captured edge fibers become spinning strand hairiness, which is then stretched and tightly wrapped onto the spinning strand stem by a negative pressure; the spinning strand is outputted from the holder groove outlet to get a high qualified spun yarn.

摘要： The present invention discloses a centrifugal spinning apparatus, including a frame, a spinning device, a feeding device for providing a spinning solution to the spinning device, and a collection device for collecting centrifugal spinning fibers ejected by the spinning device. The collection device is horizontally disposed below the spinning device, to enable the centrifugal spinning fibers ejected by the spinning device to be attached to a surface of the collection device. A planar receiving-type centrifugal spinning automatic production device using the centrifugal spinning apparatus breaks through existing centrifugal spinning based on ring collection and centrifugal spinning technologies based on electrostatic collection, resolves a preparation problem of continuous filament of the centrifugal spinning, and achieves mass production of the centrifugal spinning. The whole production process is completed automatically without manual intervention.
