Definitions

  • ABSTRACT This invention relates to a process for squeezing and/or drying a humid thread, particularly a textile thread, in the course of a treatment, such as dyeing, effected continuously on said thread during the rectilinear displacement thereof, wherein the humid thread is passed into a zone traversed by a current of air at a pressure much lower than the pressure prevailing about the thread during the operation having provoked it humidification.
  • the invention also relates to an apparatus for continuously treating a thread, for example a textile thread, applying the process as described hereinabove.
  • the present invention relates to a process and apparatus for the continuous treatment of threads.
  • Such continuous treatments generally consist in depositing a product on the thread to be treated, for example by passing this thread in a bath, then in eliminating the excess of treating fluid by scraping obtained for example by means of an air current circulating near the thread.
  • the invention firstly has for its object to remedy the above-mentioned disadvantages and relates to a process for squeezing and/or drying a humid thread, particularly a textile thread, utilizable in particular during a treatment, such as dyeing, effected continuously on said thread.
  • the humid thread is passed through a zone through which passes an air current at a pressure much lower than the pressure prevailing around the thread during the operation having provoked its humidification.
  • the low pressure zone is created in the supersonic flow of an air current at the outlet of a convergent-divergent nozzle through which the'thread passes.
  • the invention also has for its object a particular application of the above-defined process, particularly for the purpose of making dyed zones and non-dyed zones thread.
  • the thread is passed into two convergent-divergent nozzles, the second of said nozzles being permanently fed by an air current whose pressure upstream of said nozzle is higher than the critical pressure at the constriction of this nozzle, whilst the i first nozzle is fed by a current of air whose pressure upstream of said first nozzle is alternately higher then lower than the critical" pressure at the constriction of this first nozzle.
  • the invention has for its object an apparatus enabling the above-defined process and its particular application to be carried out, for the purpose of effecting on threads all types of treatments, particularly dyeing, which are continuously applied during a rectilinear displacement of the thread.
  • the present invention provides both a perfect homogeneity of the treated thread as well as high speed of the treatment.
  • thread as used herein means any supple element of very small diameter with respect to its length.
  • the apparatus comprises at least two elementary treatment chambers, each of them corresponding to a phase of the complete treatment that a thread must undergo. These elementary treatment chambers are aligned and a recovery zone is provided therebetween for the active products used in the elementary treatment chambers, at least in the first of them.
  • Each treatment chamber comprises two apertures for the inlet and outlet of the thread, these two apertures being aligned with those of the other treatment chambers in the direction of the thread and having a diameter close to this latter.
  • the shape of these apertures depends upon the nature of the treatment and will be specified later.
  • there opens out into each treatment chamber a pipe connected to a source of treatment fluid.
  • the recovery zone for the treatment fluids is shaped as a chamber which surrounds, in sealed manner, the outlet aperture of one treatment chamber as well as the inlet aperture of the following treatment chamber, whilst each treatment chamber fed with a chemically active fluid is followed by a treatment chamber fed by an inert gas, such as compressed air.
  • the recovery chamber comprises at least one pipe connected to a recovery tank for a treatment fluid.
  • FIG. 1 is a schematic view of a first apparatus according to the invention.
  • FIG. 2 is a schematic view of a convergent-divergent nozzle equipping at least certain of the treatment chambers fed by an inert gas.
  • FIG. 3 is a schematic view of a second apparatus according to the invention, applicable in particular in the case of dyeing a textile thread.
  • FIG. 4, 5 and 6 show variants of the apparatus of FIG. 3 utilizable in particular when it is desired to obtain threads having treated zones alternating with nontreated zones.
  • the embodiment described with reference to FIG. 1 corresponds to the application to a thread of a known coating treatment.
  • it enables the weight and the resistance to abrasion of a textile thread to be increased and to be made suitable for use in a sewing machine.
  • Such a treatment comprises the following active elementary phases:
  • the apparatus permitting application of this treatment comprises, aligned along the path followed by the thread A, elementary treatment chambers l, 2, 3, 4, 5 and 6.
  • the chamber 1, corresponding to the attack by the acid bath comprises a pipe la connected to a tank of acid solution, by means of a pump 11.
  • the two apertures lb and 1c of this chamber are capillary tubes whose diameter, function of that of the thread to be treated, is determined so as to avoid, or at least limit, the leaks of liquid by gravity or by drive.
  • the pump 11 maintains a constant level of liquid in the chamber 1.
  • recuperation chambers 7 and 8 On either side of the treatment chamber 1 are disposed two recuperation chambers 7 and 8. They respectively surround, in sealed manner, the apertures lb and 1c and have pipes 7a and 8a ensuring the recovery of the leakage liquid which is returned the tank 10.
  • the treatment chambers 2, 4 and 6 correspond to intermediate squeezing and possibly drying phases. Their ends are of course also surrounded in sealed manner by the recovery chambers 8, l4, 15, 16, 17 and 22. In this case, however, the treatment fluid is compressed air passed through a main pipe 9 and terminating at the pipes 2a, 4a, 6a belonging to each of said chambers. It should be emphasized that the inlet and outlet apertures of these chambers 2, 4 and 6 are each in the shape of a convergent-divergent nozzle, referenced 2b and 20 for the chamber 2. The convergent-divergent nozzles of chambers 2,
  • critical pressure designates the pressure prevailing at the constriction of a nozzle and from which a supersonic flow is obtained in the divergent part of the nozzle, although the flow is subsonic in the convergent part thereof.
  • the nozzles used in the apparatus according to the invention are preferably set out according to known methods, so that, when they exist, the shock waves provoked by the return of the air to a subsonic speed are located outside the divergent part and not, asv is frequently the case, inside said latter.
  • FIG. 2 shows such a nozzle which may be disposed at each end of the chambers 2, 4 and 6, or at least at one of said ends, preferably at the outlet end for the thread A.
  • 50 designates the wall of the chamber, 51 the convergent part of the nozzle and 52 the divergent part.
  • shock waves provoked by the return of the air to a subsonic speed appear at the end of the divergent part 52. They have been shown by a solid line and a broken line, the first shock waves 54 being of course decompression waves. They develop along the substantially conical surface 54 and reflect on themselves at the apex 55 of this surface 54. As is known, they then become decompression waves developing along the surface 56. When they have reached the zone where the constant pressure P prevails, they reflect on this zone at 57 in order then to develop along surface 58 up to its apex'59. It is known that, when shock waves reflect on a constant pressure zone, they change nature, so that the surface 58 is delimited by compression waves. Similar phenomena continue beyond the apex 59 but it is not necessary to describe them in order to understand the invention.
  • the treatment chamber 3 is similar to chamber 1 and is fed by a neutralizing bath coming from a tank 12 by means of a pump 13. It is the same for the chamber 5 which is fed by a washing bath coming from a tank by means of a pump 21.

  • the last treatment chamber 6 may open out into the free air; however, in certain cases, it may be advantageous, as shown in the drawing, to ensure a complete recovery of the air leaving this chamber. In fact, it may be charged with solid, liquid or gaseous particles which would be dangerous to allow to escape into the atmosphere.
  • the outlet aperture 6b is prolonged by a recovery chamber 22 whose recovery pipe 22a is inclined by about 45 on the axis of the thread.
  • a conduit 22b connected to the main pipe 9 for compressed air opens out into the chamber 22 and directs the fluid leaving through the aperture 6b directly into the pipe 220.
  • a drying by heating may be provided, either as an intermediate phase or as a final phase.
  • the thread passes through a capillary tube 23 surrounded by an isolating means in which a heating resistor 24 is embedded.
  • the above-described treatment may also take the form of a pure and simple attack of a polyamide thread by hydrochloric acid, the dissolution of a part of the polyamide being outside the thread forming the dissolution, the later treatment giving the effect of coagulation and leading to a final result of the same order as before.
  • Such a treatment no longer necessitates any addition of polyamide on the outer surface of the thread.
  • FIG. 3 an embodiment of the invention is shown which is applicable more particularly to the dyeing of threads.
  • it is essential suitably to dose the active product, in the present case the dye, and to be sure of the reproduceability of the modes of operation.
  • the invention enables these conditions to be easily fulfilled.
  • the apparatus comprises a first treatment chamber 31 provided with a feed pipe 31a connected to a dye tank 40 and equipped with a pump 41.
  • This treatment chamber comprises inlet and outlet apertures for the thread, constituted by capillary tubes 31b and 310 opening out into the recovery chambers 37 and 38, which surround, in sealed manner, the ends of said tubes.

  • a heating element similar to that described with reference to FIG. I may be disposed at the outlet of the chamber 32.
  • the chamber 31 may be equipped with heating means, constituted for example by electrical resistors disposed inside the chamber or surrounding this latter. Tubes may also be used through which passes a heating fluid, such as vapor, such tubes being disposable inside or outside the chamber 31. Similarly, the chamber 31 may be disposed inside an enclosure heated by any suitable means.
