摘要： An object of the present invention is to increase the maximum speed at which a false-twisted processed yarn can be produced.
In a method of manufacturing the false-twisted processed yarn Yf by using a false-twist texturing machine 1, a raw yarn Yr is a partially oriented yarn formed of PET synthetic fibers. When the partially oriented yarn is not false-twisted, the partially oriented yarn has a pre-processing elongation of less than 100%, a boiling water shrinkage of 3.7% to 25%, and a strength of 2.9 cN/dtex or more. In this regard, the pre-processing elongation is the residual elongation. Furthermore, the raw yarn Yr is false-twisted at a processing speed of 1100 m/min or more while being heated and drawn.

摘要： [Problem to be Solved] To provide a traversing device capable of performing an accurate traverse control, preventing rotating blades adjacent in an alignment direction of a plurality of traversing units from interfering with each other, and avoiding device failure.
[Solution to Problem] A traversing device (1) includes a drive motor (1), a toothed transmission belt (12), and a plurality of traversing units (13). Each of the plurality of traversing units (13) includes a traverse guide (17), rotating blades (18, 19) configured to rotate in directions opposite to each other so as to traverse a thread (101), a drive force transmission shaft (22) for transmitting drive force to the rotating blades (18, 19), and an interference avoidance cam (21). The interference avoidance cams (21) adjacent in an alignment direction (Y) of the plurality of traversing units (13) rotate without abutting each other in a state where rotation speeds of the drive force transmission shafts (22) adjacent in the alignment direction (Y) are the same, and, when a deviation occurs in rotation speeds of the drive force transmission shafts (22), the interference avoidance cams (21) abut each other so as to regulate the deviation in rotation speeds between the drive force transmission shafts (22) and to avoid interference between the rotating blades (18, 19) adjacent in the alignment direction (Y).

摘要： An object of the present invention is to properly cool filaments in a structure in which the filaments are spun out downward from a single spinneret, divided into two groups, and bundled as two yarns.
A yarn production system 1 includes (i) a spinning apparatus 2 including a spinneret 24 provided with discharge ports 26, (ii) a cooler 4 provided below the spinneret 24, and (iii) an oiling unit 5 provided below the cooler 4. A virtual partitioning plane X divides the discharge ports 26 into a first discharge port group 26A and a second discharge port group 26B. The oiling unit 5 includes a first oil supply guide 51a including a first oil supply surface 52a and a second oil supply guide 51b including a second oil supply surface 52b. The yarn production system 1 further includes a first bundling guide 30a and a second bundling guide 30b which are provided below the cooler 4 and above the oiling unit 5.

摘要： An object of the present invention is to further reliably cut and suck yarns which run while being aligned in an arrangement direction.
An yarn cutting-sucking device 40 includes: a cutter 42 which includes a blade part 42a for cutting the yarns Y and which is movable from the left side toward the right side in a left-right direction; a cylindrical member 51 which is movable together with the cutter 42 and which is configured to suck the yarns Y cut by the cutter 42; a first guide 44 which is provided upstream of the cutter 42 in a yarn running direction, which moves together with the cutter 42, and which guides the yarns Y to the blade part 42a; and a second guide 45 which is provided downstream of the cutter 42 in the yarn running direction, which moves together with the cutter 42, and which guides the yarns Y to the blade part 42a. The first guide 44 includes a first regulatory portion which regulates movement of each yarn Y in a direction in which each yarn Y is pushed as a result of contact with the blade part 42a, and the second guide 45 includes a second regulatory portion which regulates the movement of each yarn Y in the direction in which each yarn Y is pushed by the contact with the blade part 42a.

摘要： Problems which may occur when false-twisting devices are driven by a single driving source are solved. A draw texturing machine 1 includes a plurality of false-twisting devices 15 each configured to twist different yarns Y1 and Y2 in opposite directions to each other. Each of the false-twisting devices 15 includes: a disc configured to rotate; a belt unit 32 provided close to a first surface of the disc and including a twister belt 53 configured to allow the yarn Y1 to be interposed between the disc and the twister belt 53; a belt unit 33 provided close to a second surface of the disc and including a twister belt 63 configured to allow the yarn Y2 to be interposed between the disc and the twister belt 63; and a common motor 71 configured to drive the twister belt 53 and the twister belt 63. The above arrangement allows each motor 71 to have a smaller size as compared with cases in which the false-twisting devices 15 are driven by a large common motor. As a result, noise and vibration are reduced. Furthermore, there is no necessity to provide an element for power transmission through which the false-twisting devices 15 are driven by a common motor, and therefore downsizing of the overall draw texturing machine 1 is possible and the ease of maintenance is improved.

摘要： To provide a spun yarn take-up apparatus capable of cutting a yarn reliably with a yarn cutting-suctioning unit. The spun yarn take-up apparatus includes a yarn cutting-suctioning unit (30) having a cutter (32) for cutting a plurality of yarns (Y) aligned along an alignment direction each traveling and a suctioning unit (35) for suctioning the yarns (Y) cut by the cutter (32), a godet roller arranged downstream from the yarn cutting-suctioning unit (30) in a yarn traveling direction so as to feed the traveling yarns (Y) in the yarn traveling direction, and a controller configured to perform control to stop the godet roller when the yarn (Y) is cut and suctioned by the yarn cutting-suctioning unit (30). The plurality of yarns (Y) and the cutter (32) and suctioning unit (35) are caused to move closer to each other, whereby the plurality of yarns (Y) can be sequentially cut and suctioned. The controller stops the godet roller when at least a plurality of yarns Y (Y) are in a state of being cut.
