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： An air nozzle, suitable for producing a fasciated yarn, having at least one jet in each of narrow and wide passages along the traveling direction of the fiber bundle. Each jet is directed to generate a vortex whirling reversely from that of the other passage. The twist imparted to the fiber bundle by the vortex generated in the wide passage is restrained by the vortex whirling reversely thereto in the narrow passage. As a result, circumferential fibers of the fiber bundle are less twisted relative to the core portion thereof. During the untwisting operation of the vortex of the wide passage, the circumferential fibers are entangled around the core portion with a twist corresponding to the difference from the core portion, thereby obtaining a well-fasciated yarn.

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.

摘要： An apparatus for producing a fasciated yarn comprising two air nozzles (2, 3) arranged at an angle in such a manner that a wedge shaped space (S) is formed therebetween, in which each of the air nozzles (2, 3) has a function of rotating a fiber bundle about the axis thereof in a direction that is the reverse of the other. A yarn passage from the first air nozzle (2) and to the second air nozzle (3) is so adapted that the fiber bundle is not in positive contact with an inner wall of an exit portion (7) of the first air nozzle (2) but is in contact with an inner wall of an inlet portion (4) of the second air nozzle (3), whereby a twist ascent from the second air nozzle (3) into the first air nozzle (2) is adequately suppressed and effective fasciated yarn forming is attainable. According to the wedge shaped space (S), the interference by exhaust air from the first air nozzle (2) with the second air nozzle (3) is eliminated.

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.

The collector means in the shape of a hollow shell is disposed between a preceding draft means such as a pair of front rollers and the post draft means such as a pair of a aprons, in such a manner that a front surface of the collector means confronts a rearward surface of the preceding draft means and, on the other hand, a rear surface of the collector means confronts a front surface of the post draft means with a predetermined clearance. By this construction, a concomitant air stream accompanying rotation of the draft means is effectively expelled out of the fiber passage and stable drafting can be accomplished.
