    摘要： In a pneumatic nozzle utilized in the process of producing a fasciated yarn, provided with a transporting passage of a fiber bundle in which an inlet portion, a smaller channel, and a large channel having an outlet opening are successively arranged along the longitudinal axis of the transporting passage, and a plurality of air supply apertures for ejecting compressed air toward a restricted region of the transporting passage, a plurality of small chambers formed around the large channel is symmetry with respect to the large channel's longitudinal axis and connecting apertures for connecting the large channel to the outside of the nozzle so that air introduced into the large channel through the inlet opening and the air-supply apertures can be partly discharged, while the remaining part of the above-mentioned air is discharged from the outlet of the large chamber. In this nozzle, a supplemental ring can be used to adjust the air condition in the large chamber by mounting on a discharge end portion of the nozzle.

    摘要： A false-twist nozzle with an improved structure is provided herein. The false-twist nozzle according to the invention comprises a housing having a large-diameter yarn passage portion and an insert member having a small-diameter yarn passage portion and a fluid conduit hole. When the insert member is within the housing, a complete yarn passage hole is formed through the nozzle. Because the insert member is separable from the housing, drilling of the very small diameter fluid conduit hole can be made easily and accurately prior to insertion within the housing. Furthermore, the fluid conduit opening is disposed both annularly and angularly in the downstream direction with respect to the yarn passage hole, thereby increasing the twisting action induced by the flow of jetted fluid while preventing damage to the yarn.

    摘要： A method and an apparatus for producing a fasciated yarn, utilizing an air nozzle for false-twisting a fiber bundle. The apparatus is provided with a fiber passage comprising an inlet portion, a small channel, and a large channel, and is provided also with a contact area on an inner wall of the small channel, this contact area being formed by the intersection at an angle of the small channel and the large channel.During the spinning operation, the fiber bundle is forced against the contact area, effectively suppressing a twist imparted by a vortex such that it does not ascend toward the upstream region.Also, since ballooning can be suppressed by the contact area, the size of the small channel can be increased, resulting in the intake by suction of a sufficient amount of air in the inlet portion.

    摘要： An air nozzle utilized for false-twisting a fiber bundle to form a fasciated yarn, comprising, in series, an inlet and a fiber passage provided with at least a jet for generating a vortex within the fiber passage. The inlet has an opening of a flattened shape having upper and lower walls longer than the side walls thereof and has a size decreasing toward the fiber passage. The edge portion of the ribbon-like fiber bundle passing through the air nozzle strongly contacts the upper and lower walls of the inlet during the twisting operation by the vortex. As a result of frictional resistance with the walls, the twist angle of the edge portion fibers becomes less than that of the core portion fibers. This causes a tightly fasciated effect of the edge portion fibers onto the core portion fibers during the untwisting operation.

    摘要： A false twisting air nozzle for use in fasciated yarn spinning and the like. The air nozzle has a fiber bundle passage for allowing a fiber bundle to pass therethrough in a direction, the fiber bundle passage including an inlet, a smaller-diameter hole portion, and a larger-diameter hole portion which are arranged in series. An air injection hole has end opening tangentially and downstream in the larger-diameter hole portion. Air passages are disposed around the smaller-diameter hole portion and held in communication with the larger-diameter hole portion for increasing the force with which the fiber bundle can be drawn into the air nozzle. The air passages may be a plurality of slots defined in an inner wall surface of the smaller-diameter hole portion or a plurality of independent holes defined radially outwardly of the smaller-diameter hole portion.

    摘要： The present invention relates to a three dimensional fabric including a warp layer consisting of a plurality of warps arranged in parallel along a longitudinal direction of the fabric, bias threads arranged in inclined directions with respect to the longitudinal direction of the fabric in a place parallel to the warp layer, and a vertical thread arranged in a thicknesswise direction of the fabric such that it perpendicularly intersects the warps. It also relates to a method of producing the fabric. Where such fabric is employed for a composite material in which a resin or the like is used as a matrix, the composite material deforms less under the influence of forces acting in an oblique direction. It therefore has an increased range of applications as a structural material comparing with a conventional 3-axis three dimensional fabric. Further, the subject of the present invention resides in provision of a three dimensional fabric having an arrangement of threads of such bias directions and a producing process by which such three dimensional fabric can be produced comparatively readily. A bias thread layer is composed of a large number of continuous bias threads which are arranged such that they are inclined symmetrically to each other with respect to a longitudinal direction of the fabric in a plane parallel to the warp layer. Each pair of bias thread layers make a set. The engaging positions of the bias threads with a set made of each two thereof which are in an engaging condition with engaging portions of a feeding device disposed between the cloth fell position and a bias thread supplying section are moved by a predetermined pitch in opposite directions to each other for each of the bias thread layers along widthwise directions of the fabric by an action of the feeding device. Such movement of the engaging positions and insertion of vertical threads are performed alternately.
