Description

583359 V. Description of the invention (1) [Technical Field] The present invention relates to a spinning method of a component yarn after the spinning is interrupted during the winding of the component yarn. The component yarn includes a continuous component and a component yarn. The spinning component made by picking out the fibers from a single head on a rotor spinning machine has first taken the step of preparing the component yarn wound on a bobbin for spinning, and preparing the continuous yarn. The step of preparing the component for restarting spinning, and the step of preparing the spinning rotor for restarting spinning. The invention also relates to a device for performing the method. [Background of the Invention] Generally speaking, the conventional method of spinning component yarns does not solve the problem of how to restart spinning that is interrupted for any reason. The component yarn includes continuous components and Single head picks out the components made of fibers. The problem is that, especially in yarns containing elastic continuous components, restarting cannot be performed in the usual way, i.e. by putting the spinning rotor back into the end point of the yarn and by The single-fed-out fiber ribbon in the spinning rotor is connected to the continuous component, because the component yarn, especially those with elastic continuous components, will change its shape when interrupted, and in its free The ends show loops, preventing the end point of the component yarn from being introduced from the spinning rotor. U.S. Patent No. 4,30,2,925 discloses the restart of spinning on empty tubes, in which the end point of the auxiliary yarn is introduced into the spinning rotor and guided here in a well-known manner into the A single end of the spinning rotor picks out a fiber band connected to the fiber band. Then, the drawing of the yarn spun by the auxiliary yarn and the rayon staple fiber is started, and the drawn yarn is guided to the outside of the wound bobbin, and the continuous component supply of the yarn is started according to this The spinning turn

92050.ptd Page 7 583359 5. In the description of the invention (2), the continuous component of the yarn is connected with the yarn that produces the single-ended picked fiber, so that the component yarn is formed, and then the yarn is formed by a well-known method Once the component yarn is placed on the empty tube, the winding of the component yarn on the empty tube and the arrangement of the take-up bobbin are started. In general, the well-known device for spinning component yarns in the rotor system does not at all solve the restart of spinning after yarn splitting that occurs during the spinning and winding process, especially for Component yarn with elastic continuous component. After the yarn is split, the bobbin is replaced and the winding is started on a newly inserted empty tube after the yarn is spinning-in. The present invention intends to propose a method that allows the winding of the component yarn to be started on the bobbin that has been wound beforehand and the spinning of the component yarn to be restarted. [Principle of Invention] The purpose of the invention has been achieved by restarting the spinning method of a component yarn, which includes a continuous component, especially an elastic continuous component, and a single head on a rotor spinning machine. The principle of picking out the spun component made of fibers is to prepare the end points for connection with the component yarn from the rotor, and then connect the two end points of the component yarn and The spinning of the component yarn on the bobbin is started again to achieve the preparation step of the component yarn wound on the bobbin. The connection of the end points of the component yarns, especially those having an elastic continuous component that is wound on a bobbin from the rotor to be spun into component yarns, is connected to a coil that is allowed tolerance tolerance All bobbins around a predetermined winding length and therefore facilitate the subsequent processing of the component yarn produced. This is caused by

Description of the invention (3) In some technical departments such as advanced wiring of knitted component yarns, as long as the tolerable defects that are not visible to the end user of the end product need not necessarily be regarded as the final Facts about the flaws of the product. For certain techniques of the end point process of component yarns, it is advantageous if the end points of the component yarns wound on the bobbin are used by some well-known functional parts in the weaving industry It is connected with the component yarn from the rotor. In most of the subsequent yarn manufacturing techniques, it is advantageous if the connection of the component yarns is achieved by interweaving their endpoints with each other with a flow of gas, fluid, or a combination of them. The principle of the method according to the present invention also lies in the preparation steps for the preparation of the end points of the component yarns. The preparation step is a component that is spun out of the single-ended fiber in the spinning rotor with an auxiliary yarn. And the component yarn is pulled out of the outer side of the bobbin to wind up the component yarn which is then fed into the spinning rotor by the continuous component supply. The spun component of the single-ended picked fiber is connected and a component yarn including the spun component of the single-ended picked fiber and a continuous component that continues to guide the component yarn on the outside of the bobbin is produced, such that The component yarn is wound up, and accordingly the end point including the auxiliary yarn is cut in a section, in which the component yarn includes each component of the two components, and the The ends of the component yarns of the rotor are used for wiring to the ends of the component yarns wound on the bobbin, and the two ends are connected. The method according to the present invention allows the spinning and winding of the yarn to be restarted after the yarn is split, to a certain extent, even when the continuous component system

92050.ptd Page 9 583359 Description of the invention (4) ___ When elastic, only the sentence red can be wound on the bobbin: the component yarn of all components with continuous components is ensured at the end of the yarn of the rotor The point of the component yarn is to prevent the end points of the divided yarn pulled by the rotor from being equal. The same point is made next to the starting point of the component yarn after the component yarn is accelerated and restarted to maintain the 'And it is only universally combined with the end which is used to connect the component yarn. The spinning operation of the component yarn of the component yarn is carried out. The speed of the spinning operation of the component yarn when the spinning operation of the component yarn is pulled out will generate a temporary supply on the bobbin. If the temporary yarn is inferior during winding, The increase of the winding and the winding constant at the increased speed past the end point of the yarn with the same performance as the spun point of the normal operation patent rotor, and before the start. In the loop formation, the end point of the yarn separation is completed, and the excess spinning material of the rotor is prevented from being spun. The consumption speed of the feed, and the grouping degree on the bobbin until the end position of the component yarn in the winding speed range of item 1 is suitable for quality. It has to be wound on the bobbin to obtain the operation. The component yarn that is spun with the yarn wound around the yarn is connected and threaded and / or the end point of the yarn whose extension ends is extended and the component is temporarily decorated and wound in the method The benefit of the machine is that if the component on the tube is spun at least until the sheet of component yarn on the bobbin is temporarily placed and wound, the yarn is wound and the connection of the group wound with the rotor is opened. Consumption principle of yarn handling is based on the following operating unit on the bobbin
