51292 results about "Yarn" patented technology

Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, or ropemaking. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Embroidery threads are yarns specifically designed for needlework.

Suction nozzle of electronic atomizer

InactiveCN101843368AOvercome the defect of large air intake resistanceTobacco devicesMedical atomisersYarnFiber
The invention relates to a structural improvement on a suction nozzle of an electronic atomizer. The suction nozzle comprises a cylindrical outer shell, a front end cylindrical hole part of the outer shell is fixedly connected with a threaded electrode of the suction nozzle, a rear end cylindrical hole part of the outer shell is provided with a seal wall, a heater and fiber yarn are accommodated in an accommodating cavity of the outer shell, the fiber yarn can be used for storing atomized liquid, the heater is electrically connected with the threaded electrode of the suction nozzle, the threaded electrode of the suction nozzle is provided with an inner electrode and an outer electrode, the threaded electrode of the suction nozzle is provided with an air inlet, an air outlet is arranged in the seal wall, the fiber yarn is annularly distributed into the accommodating cavity, an axial central channel is formed in a middle position and is communicated with the air inlet and the air outlet, the heater is fixed in the central channel, the inner wall of the central channel is provided with a dispersion cloth layer of dispersion liquid, and at least one part of the central channel is fixedly connected with a hollow supporting pipe. Owing to the technical characteristics, the suction nozzle of the electronic atomizer can be applied to a device which can atomize odorant liquid for a user to suck.

Endovascular graft with differentiable porosity along its length

InactiveUS20050137677A1Promote tissue in-growthAchieve effectSuture equipmentsStentsPorosityYarn
Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device such as a stent-graft. These therapeutic drugs, agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. In addition, these therapeutic drugs, agents and/or compounds may be utilized to promote healing, including the formation of blood clots. A stent-graft fabricated from a thin-walled, high strength material provides for a more durable and lower profile endoprosthesis. The stent-graft comprises one or more stent segments covered with a fabric formed by the weaving, knitting or braiding of a biocompatible, high tensile strength, abrasion resistant, highly durable yarn such as ultra high molecular weight polyethylene. The one or more stent segments may be balloon expandable or self-expanding. The fabric may be attached to the stent segments utilizing any number of known materials and techniques. In addition, the pore size of the graft material may be varied.

Positioning spinning method of embedded system

The invention relates to a method for positioning yarn by an embedded system, belonging to the technical field of textile processing. The method comprises the technical proposal that: on a drafting mechanism of a ring spinning frame, two chopped fiber rough yarns unreeled from a rough yarn bobbin enter a drafting zone respectively in parallel to be drafted by yarn guiding horns; two continuous yarns are fed from the rear end of a front roller, and join with the two crude yarn strands respectively at a front jaw; the two drafted crude yarn strands and the two continuous yarns are output from the front jaw, enter a twisting triangular zone to be twisted, and are wound on a spun yarn bobbin into yarn; according to different relative positions of the two crude yarn strands and the two continuous yarns, yarns with various structures can be formed. The method can realize that polycomponent yarns with a core-spun structure, a fasciated structure and a folded yarn like structure can be spinned on the ring spinning frame; the yarn structure can be accurately selected and determined and is closer, and yarns has more excellent hairiness, brute force and evenness; and spinning of special fiber yarns on the traditional spinning equipment can be realized so as to enlarge the range of spinning materials.
