摘要： A process for manufacturing a yarn includes twisting the yarn in a first direction for a predefined number of twists. The method also includes, after the predefined number of twists, twisting the yarn in a second direction for a predefined number of twists, the predefined number of twists for the second yarn is same as the predefined number of twists for the first yarn. The twisting of the yarn in the second direction creates an air bed within the yarn's fibers.

摘要： A method and associated textile machine are provided to produce a roving having a protective twist from a fiber bundle fed to a consolidating means. The produced roving is wound with a winding device onto a tube arranged at a winding position. After the wound tube has been fully or partially wound with the roving, a tube change is initiated. During the tube change, the wound tube is removed from the winding position and an empty tube is moved into the winding position. During the tube change, the roving is wound onto the wound tube at least until the roving comes into contact with the empty tube as a result of the tube change such that the production of the roving is not interrupted during the tube change. During the tube change, the roving is wound onto the wound tube in a region that lies outside a region last wound prior to the tube change.

摘要： A spinning preparation machine includes a consolidating means for producing a roving having a protective twist from a fiber bundle, a drafting system arranged upstream of the consolidating means, a winding device arranged downstream of the consolidating means, and a movably mounted traversing element adjacent the winding device to guide the roving being wound onto a tube. In a side view of the spinning preparation machine, the consolidating means is arranged vertically between at least one feed roller of the drafting system and the traversing element, and the feed roller and the traversing element are arranged on a same side of the consolidating means so that in operation of the spinning preparation machine, the roving experiences a change in direction after exiting the consolidating means and prior to being wound onto the tube.

摘要： Nanofiber based sensors are described that can be used to detect analytes in biological or non-biological contexts. Each sensor includes at least two nanofiber yarns that are spaced apart from one another so as to avoid electrical (or physical) contact. Each nanofiber yarn of the nanofiber sensor includes a sensing region that is in electrical contact with the rest of the corresponding nanofiber yarn. The sensing regions of the at least two nanofibers are treated with complementary sensing agents so that when the sensing regions (and the corresponding sensing agents) are exposed to the analyte to be detected, an electrical response is detected. This response is then communicated through one or more of the nanofiber yarns for interpretation by a processor.

摘要： The invention relates to a method for the resumption of the spinning process on an air-jet spinning machine, in which after an interruption in the spinning process has occurred, yarn (5) is guided back to its working path behind a spinning nozzle (4), or the yarn is stopped in a controlled manner in the working path with the end of yarn behind the spinning nozzle, the end of yarn (5) being introduced to the outlet opening (41) of the spinning nozzle (4), whereupon the yarn (5) is transported by a reverse motion by means of the spinning nozzle (4) and a feeding device (3) of sliver (0) as far as to a guide channel (2) before the spinning nozzle (4), where on the yarn (5) in the guide channel (2) a spinning-in end of yarn is formed and the yarn (5) reserve starts to be created in an underpressure yarn storage device (73) in front of the winding device (9) of yarn. Before, simultaneously with or after the formation of the spinning-in end of yarn (5) the winding of the yarn (5) on the bobbin (90) is started, whereupon before the yarn (5) reserve from the underpressure yarn storage device (73) is used up, the yarn starts to be withdrawn (5) by the drawing-off mechanism (6), whereby following the start of the withdrawal of the yarn (5) the yarn is clamped by the rotating feeding device (3) of sliver (0) and the feed of new fibers through the drafting device (1) to the feeding device (3) of sliver (0) is started.

摘要： The invention relates to a spinning preparation machine having at least one consolidating means for producing a roving (3) that has a protective twist and that is made of a fiber bundle (4) supplied to the consolidating means, having a drafting system (5) for drafting the fiber bundle (4) before the latter enters the consolidating means, wherein the drafting system (5) is arranged upstream of the consolidating means in a transport direction (T) of the drafting system (5), having a guide (6) arranged upstream of the drafting system (5) in the aforesaid transport direction (T) for guiding the fiber bundle (4) between a container (7) providing the fiber bundle (4) and the drafting system (5), wherein the guide (6) has a feed segment (8) facing away from the drafting system (5) for the fiber bundle (4) originating from the container (7) when the spinning preparation machine (1) is in operation, and has a delivery segment (9) facing the drafting system (5) for the fiber bundle (4), wherein the spinning preparation machine (1) has a winding device (10) for winding the roving (3) onto a tube (11), and wherein the spinning preparation machine (1) has a tube transport device (12) for providing empty tubes (11) and/or for removing tubes (11) loaded with roving (3) by means of the winding device (10). In accordance with the invention it is suggested that the tube transport device (12) comprises at least one conveyor (13) for transporting empty tubes (11) and/or tubes (11) loaded with roving (3), wherein the conveyor(s) (13), in a top view of the spinning preparation machine (1), are arranged at least in part between the feed segment (8) of the guide (6) and the drafting system (5).

摘要： A frictional false twister is disclosed. The twister has a plurality of rotating friction plates located between the nip of the front rollers and the yarn guide. The friction plates are staggeringly arranged for rubbing a twisted yarn. The spinning direction of the twisted yarn is opposite to the rotating direction of the friction plates. Through the action of the frictional false twister, the twist of the yarn between the false twisting device to the front nip can be increased, shortening the twisting triangle height, and increasing the spinning strength. As the yarn and the outer surface of the friction plate make relative sliding and rubbing, the friction damping force correspondingly reduces the spinning tension in the twisting triangle.

摘要： To produce a mock yarn which is similar in appearance to a true yarn with respect to the ability to discern the components of the mock yarn after the twist has been imparted to the mock yarn, the rovings or slubbings forming the mock yarn, after drafting separately but parallel to one another in a drafting frame, are subjected separately to condensing and compaction by suction rollers or belts provided with rows of perforations. Thus compacted and condensed rovings are then combined, twisted and wound up as mock yarns. A core thread can be introduced into each roving or into at least one of the rovings upstream of the last pair of drafting rolls or immediately upstream of the condensing unit for a core mock yarn.

摘要： A spinning machine has a third guide eye rail, a third balloon-confining ring rail and a traveller ring rail each of which may be operated by a flexible member from a windless drum and the latter can have an electric motor drive. According to the invention, instead of storing all of the points defining the time course of the movement of the rail, a selected number of points such as starting points for the mean path and amplitude, one or more envelopes, and the amplitude or double amplitude of the oscillation superimposed upon the mean path are determined and a corresponding time course is generated. From the time course at given times determined by the oscillation, the maxima and minima of the path is produced by the evaluation and control unit and used to reverse the motor which raises and lowers the respective rail. By eliminating the need to fully plot and store points representing the entire path, the storage capacity of the computer of the unit can be more limited and control is more reliable and precise.
