摘要： Provided is a carbon-fiber-precursor acrylic fiber bundle which can smoothly pass through a flame-resistance impartation step and a carbonization step. The carbon-fiber-precursor acrylic fiber bundle has a high-density part as a portion thereof, wherein the high-density part satisfies the following requirements (A) and (B). Requirement A: The high-density part has a maximum fiber density ρmax of 1.33 g/cm3 or higher. Requirement B: The portion extending between an intermediate-density point and a maximum-density-region arrival point has an increase in fiber density of 1.3×10−2 g/cm3 or less per 10 mm of the fiber bundle length. The term “intermediate-density point” means the site which has a density ρm that is intermediate between the fiber density ρo of the non-high-density part and the maximum fiber density ρmax. The term “maximum-density-region arrival point” means the site Pr at which the increase in fiber density per 10 mm of the fiber bundle length becomes 1.0×10−3 g/cm3 or less, the increase in fiber density being represented by (ρr+0−ρr)/5 determined from a measurement in which density measurement points beginning with the point where the density begins to increase and located at intervals of 50 mm are successively examined for fiber density (ρ1, ρ2, . . . , ρr, . . . , ρn).

摘要： The yarn to be loosened is guided by slots (7;8); it is held on one side thereof and it is cut on the other side. Air is injected by a nozzle (13) for driving the cut end of the yarn into a channel (1), between the bottom (11) of this channel and the longitudinal edge of the adjacent flexible leaf (10) which is vibrated simultaneously at several hundreds of Hz. The air can escape sidewise through a longitudinal opening (4) of channel (1) and entrains the yarn from one side to the other side of the leaf (10) and imparts to this yarn alternatively inverted twists. A further action of the leaf (10) is to pulse the air in the channel and therefore to subject the yarn to intermittently applied pulls.

摘要： The invention relates to an apparatus for splicing textile threads by means of compressed air in a mixing chamber, with a device for pretreating the ends of the threads which comprises nozzles controllably feedable with compressed air and arranged at the sides of the body in which the mixing chamber is defined. The jets of air caused to leave the nozzles interfere with the cut ends of the threads laterally leaving the mixing chamber and cause them to be subjected to flapping and to a free whipping for opening and separating the fibres and putting the latter parallel to each other. A whirling motion may be imparted to the jets of air to remove the original twist from the fibres.

摘要： A device for the pneumatic splicing of yarns, especially elastane yarns, has a splicing body (25) defining a splicing conduit (26) loadable with compressed air, as well as with pneumatic tubes (33, 34) for pneumatically preparing the yarn ends (31, 32) to be spliced, wherein the central axes of the pneumatic tubes intersect the central longitudinal plane of the splicing conduit. The pneumatic tubes (33, 34) are replaceably fixed in bores (46, 47) of the splicing body (25), with the inlet opening (48, 49) of the pneumatic tubes (33, 34) positioned in the immediate vicinity of one of the two outlets (50, 51) of the splicing conduit (26). The inlet opening (48, 49) of the pneumatic tube (33, 34) has a funnel-shaped contour (52) that promotes insertion of the cut ends of the upper and lower yarns (31, 32) into the pneumatic tubes (33, 34).

摘要： The method involves the use of two nozzles (5 and 6) which alternatively blow air jets against a yarn in the central portion of a channel (1), these nozzles being symmetrically placed in relation to a plane containing the channel axis. The jets blowing frequency is of several hundreds of Hz. A deflector (3) in the bottom of channel (1) can deviate the beating thread sidewise and consequently impart thereto alternate twisting and untwisting motion in order to unravel the thread.

摘要： In a method and apparatus for preparing yarn ends, two yarns to be joined together by pneumatic splicing are placed in a splicer head of a splicer at a given instant with ends of the yarn to be prepared protruding out of a splicing channel of the splicer head in mutually opposite directions. The yarn ends are held taut at given points. The yarn ends protruding from the splicing channel are shortened to a length required for a splicing process by cutting off portions of the yarn ends between the given points and the splicer head and producing cut edges. The yarn ends to be prepared are aspirated with the cut edges leading into respective preparation nozzles at a predetermined speed. Twists in the yarn ends beginning at the cut edges are pneumatically unravelled with compressed air during the aspiration into the preparation nozzles. Locations of the yarns in the splicing channel are maintained relative to one another and to the splicing channel from the given instant until the pneumatic unraveling is completed. The yarn ends are aspirated far enough to prepare a yarn length for splicing being optimally matched to applicable yarn parameters while a not-unraveled portion of the yarns remains stationary in the splicing channel. The duration and intensity of preparation of the yarn ends are adapted to the yarn parameters.
