Abstract

PURPOSE:To enable the sufficient winding of even a short fiber having low elongation and high flexural rigidity around a core fiber by placing two belt-type false twisters and two suckers in a specific state between a front roller and a delivery roller of a drafting apparatus. CONSTITUTION:Two belt-type false twisters 13, 14 are placed between a front roller 11 and a delivery roller 12 of a drafting apparatus in such a manner as to get the twisting directions opposite to each other. A sucker 19 for the sucking of fiber is placed between the roller 11 and the twister 13 and a sucker 20 for the feed of fiber into the twister 14 is placed between the twisters 13, 14. The gyration flow of the sucker 19 is made to be weaker than that of the sucker 20 to set the twisting force applied by the twister 13 to be smaller than the force of the twister 14.

[Industrial Application Field] The present invention is directed to an If71i axis device, in particular, by heating a drafted A string bundle, one end is made to be inside the core lJi fiber in the central portion, and the other end is positioned outside the core fiber, and the other end is placed outside the core fiber. This invention relates to a device for obtaining a bound spun yarn by winding the end fibers around the outside of the core fiber. K Prior Art Following the front roller 1 of a drafting device, a pneumatic false twisting nozzle 2. Twister belt 3. A delivery roller 4 is provided, and the end fibers are wound around the surface of the core fiber by heating the drafted staple fiber bundle coming out of the front roller 1 of the drafting device. In this device, when the fiber bundle is twisted by the twister belt 3, ballooning occurs in the fiber bundle, which extends to the front bottom roller 1. Due to the ballooning, The short fibers constituting the fiber bundle have their bases embedded in the II & fiber bundle core fibers, and their tips are free, but when the free end fibers pass through the nozzle 2, In the nozzle 2, the core fibers receive a pressure jet flow and become entangled with the surface of the core S fibers, causing the core to tighten by +1. The entanglement of the core fibers with the surface changes depending on the strength of the jet air flow. However, if the amount and velocity of the ejected airflow are large, the strength will increase, but the free ends of the short fibers will easily separate from the core Si fibers.The end fibers away from the core fibers will have a fine fluff-like This is particularly likely to occur in short fibers such as cotton and raw material slivers with low elongation and bending. In view of the above points, the free ends of the short fibers that become the wrapped fibers are sufficiently wrapped around the core fibers, and even short fibers, low elongation, 9 large bending stiffness fibers, etc., are stable. The purpose is to enable spinning.

A fiber suction sucker was provided in front of the first false-twisting device, and a fiber feeding sash J- was provided in front of the second false-twisting device. [1] The sliver troughed by the draft device is sent out as elements from the front roller. This element is collected and suctioned by a fiber suction suction device and placed in a first false twisting device, and a balloon is generated in the element by this false twisting. By rotating the balloon, the other end of the short fiber, one end of which is inside the core of the element, is detected on the outer periphery of the core fiber. Then, by heating in the opposite direction with the second false twisting device,
The ends of the fibers exposed on the outer periphery of the element are wound around the core fibers as a wrapping fiber t. This winding is tightly wound by the nip pressure of the false twisting belt. After heating, the thread is sent out by a delivery roller. K Embodiment Next, an embodiment of the apparatus of the present invention will be described with reference to the drawings. A first twister 13, a twister 14 of la2 is installed between the front roller 11 of the draft device and the delivery roller 12. An endless bell is installed between the pulleys 15 and 16 of the first twister. Two false-twisted belts made by stretching the belts 1 to 17 are crossed in an X shape with their outer peripheral surfaces abutting each other, and the intersecting surface is the nip surface 18.Second twister - has the same structure as the first twister, but the crossing direction of the belts is reversed so that the twisting direction is opposite.Front roller 1 and first twister 13 A fiber suction sucker 19 is provided between the front roller 1 and the fiber suction sucker 19, which sucks the element sent out from the front roller 1 and sends it to the first twister 13. is provided with a sucker 20 for feeding the yarn into the second twister 14. Both suckers 19 and 20 have a yarn passing path in the center, and the suckers 19 and 20 have a yarn passing path in the center. It has a pressurized air outlet opening in the tangential direction and obliquely in the yarn feeding direction.The sucker 19 has a weaker swirling flow than the sucker 20.It approaches the nip surface 18 of the second twister 14. A suction nozzle 21 with an open tip is provided.The suction nozzle 21 is used when threading the thread for the first time.The suction nozzle 21 is used when threading the thread for the first time. The yarn is conveyed to the knotter via a delivery roller.When the yarn splicing is completed, it leaves the position indicated by the dashed line in the drawing.The spinning principle will be explained next.The fiber bundle passing through the second twister 14 is
False twist is added at step 8. l by the second twister-14
The false twist imparted to the Ii# bundle passes over the M1 twister 13 and is transferred to the vicinity of the front roller 1. This transmitted twist creates a triangular converging part of IS fibers in front of the front roller 11, but both this triangular part and the twisted part that follows it are connected to the front roller 1 and the seventh twister. 13, the balloon is formed by the twisting action of the first twister 13. Therefore, the twisting force of the first twister is set to be smaller than that of the second twister (belt nip pressure is smaller). Due to the above-mentioned balloon, the fluffy and loose particles protruding from the front and triangular portions of the front roller 1 are wound around the outer periphery of the fiber bundle.・NJ: The direct abrasion action of the second twister 111 causes the fibers to be more deeply and fully wrapped, and then the untwisting action after passing through the second twister 111 causes the above-mentioned outer winding (-1 fibers are wound around the core fiber bundle). In this way, unlike the tied spun yarn using air nostle, in this defense, the fluffy outer circumferentially wound fibers are pressed onto the core fibers by the bell 1 that directly touches the fibers. "Effects of the Invention" The device of the present invention is capable of transferring Freon 1 to 0- of device 61 to Drano 1.
Next to the first belt, two endless plate twisted belts supported by a pair of pulleys are placed in front of the telly roller. Two second false-twisting devices are installed with different twisting directions, a fiber suction sucker is placed in front of the first false-twisting device, and a fiber suction sucker is placed in the 61st position of the second false-twisting device. The first nozzle of the fluffy fibers is equipped with a sucker for feeding the fluffy fibers. As a raw material sliver, 100% cotton, etc.
The effect is more pronounced when a single fiber is short and has high bendability, or when a raw material with low elongation is used.
