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 half-slide matched device and its application for ultra-smoothly reconstructing yarn hairy structure belong to a textile processing field. According to the half-slide matched device of the present invention, a vortex device static part and a vortex device moving part are matched. In practice, multiple devices are connected in tandem. When yarn moves, the parts of half-slide matched device are closed, for efficiently constraining and utilizing the vortex airflow. A directional jet tube one-directionally stretches hairiness on yarn surface to avoid hairiness random dispersion and entanglement, remove yarn surface impurities. Tandem-connected devices repeatedly superimpose and strengthen the reconstructed ultra-smooth yarn structure. The half-slide matched device can be opened when the yarn breaks, which facilitates splicing and maintenance. The half-slide matched device has a reasonable structure and is very convenient for wide application.

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： Method and apparatus for producing ultra-smooth knitted fabric using hairy yarn belong to a technical field of textile. Yarn is false-twisted in a rotary holding form, for rotating the yarn stem on an ironing face. Meanwhile, a directional hairiness stretching device directionally ejects a steam flow towards the yarn, for reversely and orderly pre-wrapping hairiness on the rotating stem of the yarn, which avoids the yarn imperfection occurrence as the hairiness randomly or vertically wrapping onto the yarn stem. A vortex hair-wrapping device is used, so as to reversely wrap all the rest hairiness on the stem of the yarn, wherein a wrapping direction is opposite to a yarn moving direction for increasing difficulty of pulling out the wrapped hairiness during weft knitting, and increasing hair-wrapping tightness and fastness. The ultra-smooth yarn treatment apparatus is reasonably constructed and easily operated, which facilitates wide application.
