WORKSTATION OF AN AIR-SPINNING MACHINE, AND THREAD-GUIDING ELEMENT
The invention relates to a thread-guiding element and to a workstation of an air-spinning machine, the workstation comprising an air-spinning device for spinning a thread from a supplied sliver, a thread-guiding unit, which is downstream of the air-spinning device and has an inlet opening for receiving the thread exiting from the outlet opening of the air-spinning device and a thread guide channel for conducting at least the air-spun thread coming from the air-spinning device, and a thread-guiding element for arranging between the outlet opening of the air-spinning device and the inlet opening of the thread-guiding unit. In order to provide a workstation of an air-spinning machine and a thread-guiding element for use at a workstation of a spinning machine, more particularly an air-spinning machine, which ensure that a thread end is reliably returned to the spinning device, it is provided that the thread-guiding element a channel body having a through-channel, which channel body has: a connection section, which is designed for connection to the spinning device and is provided for arranging a first open end of the through-channel in the area of the outlet opening of the spinning device; and an end section, which can be arranged facing the inlet opening, wherein the end section, in order to receive a thread exiting from the inlet opening, is matched to a contour of the thread-guiding unit surrounding the inlet opening.
OPTICAL CABLE REINFORCEMENT WITH LOW ACIDITY
Embodiments of the disclosure relate to an optical fiber cable. The optical fiber cable includes a cable jacket having an interior surface and an exterior surface. The interior surface defines a central bore extending along a longitudinal axis of the optical fiber cable, and the exterior surface defines an outermost surface of the optical fiber cable. At least one subunit is disposed within the central bore. Each of the at least one subunit includes at least one optical fiber disposed within a buffer tube. A plurality of ultrahigh molecular weight polyethylene (UHMWPE) tensile yarns are positioned around the at least one subunit and extend along the longitudinal axis. A layer of a bedding compound is disposed between the plurality of UHMWPE tensile yarns and the cable jacket.

Composite low-twist yarn towel and production method thereof
A composite low-twist towel that is formed of three parts: terry yarn, ground warp yarn and weft yarn. The ground warp yarn and the weft yarn are normal towel yarns and the terry yarn is a composite low-twist yarn. The composite low-twist yarn is composed of two yarns of different thickness, among them, the spun yarn is synthetic fiber spun yarn or filament yarn, and the thick yarn is the pure cotton yarn or the blended yarn of pure cotton and other fibers. The composite low-twist yarn is made into a warp beam through warping and sizing. Then, it interweaves with ground warp yarns and weft yarns through a towel loom or warp loom to form terry fabrics.
METHOD FOR TRANSFORMING A YARN SPINNING AND/OR TWISTING MACHINE AND MODIFIED YARN SPINNING AND/OR TWISTING MACHINE RESULTING FROM SAID METHOD
A method for transforming a yarn spinning and/or twisting machine and the yarn spinning and/or twisting machine modified according to the method to increase the height (h) of the balloon region zone (a), between the upper and lower ends thereof is provided. In order to provide the zone with two or more balloon regions (a), with means for feeding (1) the thread (2) using conventional upper guides (3), and means for tensing (4) and rolling (5) the thread (2) onto a lower collection reel (6), includes elimination of the conventional guide means (3); and the incorporation of an additional guide accessory (3′) immediately after the feed means (1), including for example, of a clip (30) or a set of rollers (32) optionally with a conveyor belt (33).
SYSTEM AND METHOD FOR GUIDING FIBERS
A fiber guide that guides fibers in a fiber processing system. The fiber guide has a surface having apertures through which fibers can pass in a direction from an upstream side of the surface to a downstream side of the surface. The apertures include at least one pair of apertures adjacent to and spaced from one another. The inlet of the first aperture is offset from the inlet of the second aperture. The offset is in the direction in which the fibers pass from the upstream side of the surface to the downstream side of the surface. A distance (d1) between the inlet of the first aperture and the inlet of the second aperture is larger than a distance (d2) between the first aperture and the second aperture measured transverse to the direction in which the fibers can pass.
Spinning apparatus, air spinning apparatus in particular, with continuous adjustment of a yarn accumulation system and related method of continuous adjustment of a yarn accumulation system in a spinning apparatus
A spinning apparatus with continuous adjustment of a yarn accumulation system includes at least one spinning head including a spinning device including a spinning chamber for yarn production, a reel on which yarn produced by the spinning device is wound, the reel being rotatably influenced by a yarn guide shaped to impart a rotation movement of the reel for winding the yarn and a traversing movement of the yarn winding on the reel, an accumulation device arranged between the spinning device and the reel and shaped to create a reservoir of yarn not wound on the reel, a joining device including joining means to join together a first yarn end associated with the spinning device and a second yarn end associated with the reel, and a processing and control unit programmed to control the yarn guide to adjust accordingly the amount of yarn accumulated in the accumulation device.
