Definitions

  • an impregnation chamber a squeezing chamber a feeding tank means for feeding said treating liquid, under pressure, from the tank to the impregnation chamber means of maintaining a partial vacuum in the tank and in the squeezing chamber.
  • impregnation of a thread with a treating liquid is usually performed by passage through a bath and squeezing. This process as well as being rather slow in most cases has in addition the drawback of not allowing the exact regulation of the final degree of impregnation of the product.
  • the present invention aims to overcome these inconveniences by proposing an apparatus which allows a thread to be completely saturated and the final degree of impregnation to be determined and uniform.
  • the said apparatus consists at least of the following elements: i
  • the inlet and outlet orifices of the impregnation chamber are preferably of convergent-divergent type.
  • the apparatus may also include at leastone recovery chamber entirely enclosing the inlet and outlet apertures of the impregnation chamber.
  • This recovery chamber is preferably connected to the tank and it is therefore also at a lower than atmospheric pressure.
  • adjustable means of controlling the pressure inside the impregnation chamber and adjustable means of controlling the partial vacuum inside the squeezing chamber.
  • FIGS. 1 and 2 show, by way of example, two possible embodiments of the apparatus according to the invention.
  • FIG. 1 shows that the apparatus includes twobasic elements through which the thread running continuously isv successively led. More specifically, element 1 is intended for impregnation, and element 2 for squeezing, of the thread.
  • Element I consists mainly of an impregnation chamber 3 in the form of a tube through which the thread to The impregnation chamber is fed under high pressure by any known means, as for instance a pump 6. To inbe treated is run axially.
  • This chamber 3 is connected I by a pipe 4 to a tank 5 containing the treating liquid.
  • this chamber 3 has a small average crosssection.
  • the inlet and outlet orifices 7, 8 are preferably of convergent-divergent type, and their smallest diameter should be approximately equal to that of the thread to be treated.
  • the inlet and outlet apertures ofthe impregnation chamber should preferably be surrounded by a recovery chamber 9 which collects the small quantity of treating liquid escaping from chamber 3 but not carried along an the thread. This excess quantity isrecycled and returned to tank 5 through apipellil.
  • the squeezing element consists of a squeezing chamber 11 which is connected to the recovery chamber 9 or eventually-to the impregnation chamber. It is connected as well to tank 5 by a pipe 12.
  • the tank is submitted to a partial vacuum which can vary from a few ten to a few hundred grams per cm this partial vacuum being brought about by an known means, as for instance a conventional vacuum pump 13.
  • the recovery chamber Qand the squeezing chamber 11 connected to this tank 5 are also subjected to a partial vacuum.
  • the thread is sent through the apparatus in the direction of the arrow by means not shown in the drawings. These means are placed at the entrance and exit of the installation and will ensure the circulation and the storage of the thread.
  • the means may be of any suitable kind and will be chosen according to the overall treating process of the thread into which the treatment according to the invention is intended to be incorporated.
  • the thread then passes into chamber ll, where it is subjected to the partial vacuum which causes a squeezing effect on the thread.
  • the outlet orifice 14 of the squeezing chamber forms a nozzle means which has direct access either to the outside ambient atmosphere or to any kind of controlled atmosphere which suits the treatment to be processed.
  • This produces a suction towards the inside of the squeezing chamber and a squeezing of the superficial coat of the liquid carried along by the thread.
  • the partial vacuum in the squeezing chamber and the squeezing at the exit of this chamber allow the excess treating liquid to be removed and a uniform superficial coating to be obtained.
  • the re moved liquid is directly recycled through a pipe which ensures at the same time the partial vacuum in the squeezing chamber.
  • the apparatus as shown in FIG. 2 consists of an impregnation chamber 3 and of a squeezing chamber 11, showing the same characteristics as described in connection with FIG. 1 but assuming as well the role of recovery chamber since it surrounds the inlet and outlet apertures of the impregnation chamber 3.
  • This chamber 11 communicates with tank 5 by just one pipe 15, this pipe allowing the excess quantity of treating liquid to be recycled and the chamber 11 to be submitted to partial vacuum.
  • the performance of this apparatus is very similar to the above-mentioned.
  • this apparatus allows the impregnation of threads travelling at high speed.
  • the apparatus can easily be adapted for the impregnation and the squeezing of sheet materials, woven materials, non-Wovens, etc.
  • Apparatus for continuous treatment of an elongated textile product by thorough impregnation with a viscous treating liquid and thereafter by controlled squeezing thereof which apparatus comprises:
  • an impregnation chamber with at least an inlet orifice and an outlet orifice, which are open for continuous passage of textile product therethrough,
  • a squeezing chamber having at least a gas actuated squeezing nozzle means forming an outlet orifice
  • Apparatus according to claim 2 further comprising at least one recovery chamber enclosing the inlet and outlet orifices of the impregnation chamber and in enclosed flow communication with said squeezing chamber, said recovery chamber being connected to the tank so as also to recycle treating liquid and to be at lower than atmospheric pressure.
  • Apparatus according to claim 1 wherein the means for ensuring a partial vacuum in the tank and in the squeezing chamber is adjustable.
  • Apparatus according to claim 7, wherein said means for ensuring a partial vacuum is constructed to create a partial pressure of from tens to hundreds of grams per cm 9.
  • Apparatus according to claim 9 wherein the means for feeding said treating liquid from the tank to the impregnation chamber is adjustable, and wherein the means for ensuring a partial vacuum in the tank and in the squeezing chamber is adjustable.
  • Apparatus according to claim 10 wherein the inlet and outlet orifices of the impregnation chamber have a convergent/divergent form.
  • An apparatus for continuous treatment of an 5 bet, elongated textile product by thorough impregnation mean 8 for ensuringapa m a1 vacuum in the squeez with a viscous treating liquid and thereafter by controlled squeezing thereof, with apparatus comprises:
  • an impregnation chamber with at least an inlet orimeans for ensunng the axlal running of the Prod" fice and an outlet orifice, which are open for con- 10 through the impregnation chamber and the tinuous passage of textile product therethrough, q zing Cham ra squeezing chamber having at least a gas actuated ing chamber,
