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： A sliding member is made of ceramics containing aluminum oxide as a main component and fluorine, the sliding member including: a surface portion having a sliding contact portion; and an inside surrounded by the surface portion, in which a concentration of fluorine on a sliding contact surface of the sliding contact portion is higher than a concentration of fluorine in the inside as obtained from element mapping by an energy dispersive X-ray spectrometer. The disk for false twisting machines includes a sliding member.

摘要： An object of the present invention is to manufacture a thick and thin yarn by a simple method.
In a method of manufacturing the thick and thin yarn, a false-twisted processed yarn Yf formed by false-twisting a raw yarn Yr formed of polyester synthetic fibers is made uneven in terms of dyeability. In this manufacturing method, the false-twisted processed yarn Yf is sent to the downstream side in a yarn running direction by a third feed roller 18 and a fourth feed roller 20 and heated by a second heater 19 including a contact surface 56. A heating temperature of the second heater 19 is set so that the false-twisted processed yarn Yf is at least partially heated to a predetermined temperature or more in the second heater 19. At the predetermined temperature, the dyeability of the false-twisted processed yarn Yf varies and the false-twisted processed yarn Yf is thermally contracted. An overfeed rate is maintained at 15 % or more. With this arrangement, the false-twisted processed yarn Yf which runs while being thermally contracted is relaxed and sent to the downstream side in the yarn running direction.

摘要： An object of the present invention is to achieve the reduction in production cost of a yarn contacted member applied to a heater.
A first heater 13 includes: a heat source 42; a heating unit 41 which extends in a predetermined extending direction and which is heated by the heat source 42; a yarn contacted member 43 which extends at least in the extending direction and which is heated by the heating unit 41; and an attaching portion which includes the heating unit 41 and to which the yarn contacted member 43 is attached. The yarn contacted member 43 has a yarn contacted surface 57 with which a yarn Y makes contact. The yarn contacted surface 57 extends at least in the extending direction, and is oriented at least toward one side in a predetermined height direction orthogonal to the extending direction. The first heater 13 further includes an elastic deformation holding unit 60 configured to hold the yarn contacted member 43 attached to the heating unit 41 while elastically deforming the yarn contacted member 43 viewed in a width direction orthogonal to the extending direction and the height direction. When the yarn contacted member 43 is elastically deformed and held by the elastic deformation holding unit 60, a cross sectional curve 59 in a cross section orthogonal to the width direction of the yarn contacted surface 57 has a predetermined curvature.
