  • Patent number: 10753014
    Abstract: 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.

  • Patent number: 10640889
    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.

  • Patent number: 10053802
    Abstract: 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.

  • Patent number: 9963807
    Abstract: 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.

  • Patent number: 9575049
    Abstract: A method for accurately testing yarn hairiness through stretching one-directionally, belonging to a technical field of textile testing, is provided. A suction pipe is provided on an external side of a laser and connected with an exhausting fan through a sleeve connector and a hose. An air inlet of the suction pipe generates a negative pressure under an effect of the exhausting fan to laterally suck the yarn running at a tension state among the laser, a projection receiver and the suction pipe. The hairiness on a yarn surface stretches straight one-directionally towards an airflow direction at a height of a center of the air inlet of the suction pipe. The one-directional straight stretched hairiness on the yarn surface is accurately projected to the projection receiver of a testing head at an equal length for accurately testing a hair amount and a hair length.

  • Patent number: 9176286
    Abstract: An optical fiber plug for high density optical fiber connections is proposed for matching with an optical fiber adapter, and includes a body with an elastic buckling member (130) to buckle the adapter, and an ejecting assembly actuated at the same time when the buckling member (130) is actuated to release the body from the adapter. The ejecting assembly includes an ejecting spring (420) and an ejecting rod (410) arranged in the body. The ejecting rod (410) is ejected from the body when the ejecting assembly is actuated, and stopped on the adapter to eject the body out of the adapter. The optical fiber plug can be automatically ejected out of the adapter when the buckling member (130) of the plug is actuated, thus solving the problem of operational difficulties caused by reducing the geometric size of the plug, and realizing high density optical fiber connections with optical fiber jumpers.

  • Patent number: 7552580
    Abstract: A method of producing a high quality of yarn by an iron-heating apparatus, including the steps of: guiding a yarn to pass between upper and lower rollers, wherein the yarn is exited at a front nip in a twisting triangle area; guiding the yarn to enter to a groove of a heating main body of the iron-heating apparatus; heating the yarn along the groove to reduce a rigidity of the yarn so as to allow the yarn to be easily twisted to form an improved yarn with high quality; and enwrapping the improved yarn on a spun yarn tube. In addition, a counter frictional force is applied at the yarn through walls of the groove such that fiber on a surface of the yarn is further twisted to the yarn for minimizing hairiness.
