Description

I Yarns obtained from continuous filaments

  are generally smooth and have an unpleasant feel.

  For example, because the spun nylon filaments have a circular section and are very slippery, they can not be used in practice without being subjected to a finishing treatment, except when

  uses them for special jobs.

  As a result, various methods have been

  to give continuous filament yarns curls, undulations or permanent entanglements for

  give them the flexibility or swelling that does not

  Do not use the threads of continuous threads.

  For example, there may be mentioned a method in which entanglements or irregular loops are imparted to the filaments using a

  turbulence of a jet of air, to make them swelling.

  More specifically, a bundle of filaments is exposed to a turbulent flow of air to separate the mono-filaments from each other and shake them violently in a disturbing zone, the filaments being removed from this disturbing zone without any tension imposed upon them, and at the moment when the filaments are removed from this disturbing zone, loops, undulations, windings or entanglements are irregularly imparted to the filaments because of the slack which is given to them, this making it possible to produce a

textured and swelling yarn.

  In this process that uses an air jet, you have to resort. a large amount of air and the process is uneconomical, especially when dealing with

fine wires.

  In this apparatus which is mentioned above, water is applied to the bundle of filaments before the filaments are introduced into the nozzle. For example and as shown in FIG. 8, water 2 is stored in a tank 1 and a bundle of filaments 4 passes through the water tank 1 before this bundle of filaments 4 is introduced into a nozzle 3, the result

  being that water is applied to the bundle of filaments 4.

  according to this method and that the filament bundle

  through the water reservoir, guides 5 and 6 must inevitably be available, and as one of the guides 6

  is placed in a position immersed in the water, the

  4 is inevitably folded in two points. Resistance is therefore imposed on the moving filament bundle in positions 5 and 6, which makes it impossible to apply uniform treatment thereto. The state of the contact between the surface of the guide 6

  which is immersed in water and the wire is constantly changing

  when there is overfeeding of the fiber bundle.

  As a result, the speed of displacement of the filament bundle is unstable, the guidance of the bundle of filaments in the nozzle also becomes unstable and this causes

  disturbances in the manufacture of textured yarns.

  Because, in general, oil adheres to

  spun, the oil contaminates the water reservoir 1, and the bundle of filaments passes through this contaminated water with consequent degradation

  the commercial value of the textured yarn thus formed.

  The present invention relates to an apparatus for manufacturing textured yarns, and more specifically a

  apparatus provided with means by which water is

  plicated to the bundle of filaments before the filaments

  are introduced into a fluid nozzle.

  A first object of the present invention is to eliminate

  undermine the disadvantage mentioned above. According to the present invention, a bundle of filaments is passed through circulating water, the bundle of filaments passing through the water without undergoing

change of direction.

  In accordance with the present invention, an opening of a water supply pipe is formed between the roller delivery units and a fluid jet nozzle, and clear water from the water supply pipe is applied to the a bundle of filaments which flows in a straight line from the rollers and towards the fluid nozzle. Due to this structural feature and according to the present invention, it is not necessary to change the direction of filament bundle displacement and to have a guide for changing the direction of this bundle of filaments. As a result, the resistance offered by this guide can be eliminated and the bundle of filaments which is fed into the fluid nozzle can be made substantially uniform, so that the texturizing treatment can be

realized in a very uniform way.

  In addition, it is easy to suspend the bundle of filaments on the water application device when the textured yarn apparatus has been put into operation.

  road, and the fact that clear water flowing perpetually

  the water supply hose can be applied to the bundle of filaments, the contamination of

beam.

Referring to Fig. 1, this is an embodiment of the textured yarn manufacturing apparatus, a filament bundle from a feed source 8 supported on a creel 7 being The nozzle box is mounted in a positive manner by means of disks 11 and 11 and is fed to a nozzle boot 12. A water application device 13 described hereinafter and a nozzle The filament layer (9) on the water is introduced into the flip nozzle and irregular balls and knots are applied to the nozzle. The filament number of the filaments of the invention is determined by the textured 1d Cii Y, so that it is possible to use the fastener 16 by means of The embodiment of the invention is then described in FIGS. 2 to 4, wherein it is guided to a device with a roller delivery device 17 and wound up to an embodiment of the water treatment device. The party The end of a water supply pipe 19 is curved so as to form a vertical portion 2.1 which is formed following an inclined portion 20, and the upper end portion and folded in a direction which separates it from the passage Y1 yarn and the pipe is cut in the vertical portion 21 along the vertical plane, a guide groove 22 semicircular section shown at ig. 4 being formed in the green portion 21 * The shape of the groove 22 is not limited to the semicircular drill shown in the drawings and this groove 22 may have a "U" shape m. The guide groove 22 is parallel to a substantially vertical line Y1 connecting the point of separation 4a of the upper roller feed wire to a wire inlet of the fluid nozzle 14. A certain distance "1" is provided between a bottom wall 21 of the groove 22 and the vertical line YI, so that the fiber bundle is not brought into contact with the bottom wall and a side wall of the guide groove 22, and This determines the position of the guide groove 22. As a result, the bundle of filaments passes through the water without coming into contact with the guide groove 22, which is shown in FIG.

  this Z passing through the space S. In the disturbance zone

  Z, the bundle of filaments is in the relaxed state due to the supercharging and subjected to the action of disturbance, separation and vortex, and is discharged through the nozzle 14 into the open air so that no voltage is applied to this beam. An O-ring 40 made of an elastic material such as nitrile rubber is placed in the part of the needle 29 reserved for its attachment and the body 28 of the nozzle, to prevent the compressed fluid sent to the nozzle from leaking and reaches on the introduction side of the
