  • ABSTRACT MATERIALS Device for the wet treatment of packed and similar [76] Inventor: Maria Maria Maria Clermont Viias, textile materials, comprising a hermetically locked en- Paseo Can Feu, 68/80, Sabadell, closure, containing the treatment bath for the materi- Spain al, and the interior of which is divided into two chambers. One of these chambers communicates with the [22] Flled' June 1971 interior of the perforated cores which carry the PP 153,945 packed material to be treated and their perforated tubular supports and the other chamber communicates [30] Foreign Application Priority Data with the outside of these cores.
  • the treatment bath volume UNITED STATES PATENTS which each time flows through the textile matter from the outside towards the inside of same is being kept 1,623,548 4/1927 Niesen ..68/l90 enclosed in i chamber which communicates with the inside of the perforated tubular supports which support the textile material, and is at same time kept separated from the remainder of the total treatment bath volume which has not passed through the textile matter.
  • This invention refers to a device for the wet treatment of textile and other similar filiform matters, and more strictly speaking, it has for its subject an improved autoclave capable of being applied in the textile industry, the purpose of which is to subject to the action of the various treatment baths the textile matters which find themselves in their various processing stages; it is specially meant for the dyeing of raw, spun or woven fabrics; this autoclave offers substantial, mainly technical, advantages in comparison to those used heretofore.
  • the filiform or textile matter is suitably packed inside the autoclave and the treatment bath or baths are being impelled through them, whereby this form of circulation within the normal autoclaves is being achieved by means of a pump or propeller.
  • the uniformity of the wet treatment of the packed textile matter depends, among the other factors, of the number of times the circulation flow of the treatment fluid is reverted through the textile matter, thus said uniformity improves considerably along with the increase of said number of reversals, but since the pumps own inertia does not allow to revert its movement at a high frequency, it results that a relatively considerable time is needed to perform the necessary reversals of the treatment baths direction of flow.
  • this wet treatment consist in a dyeing process, it is, furthermore, utmost essential to have a treatment bath temperature control, for the temperature has an utmost marked effect on the absorption velocity of dyestuffs by textile matters and on the total quantity of dyestuffs absorbed by the fiber at the end of the dyeing process.
  • the absorption velocity constant K varies exponentially with the temperature so that when the temperature increases the absorption velocity increases notably.
  • the value of this increment depends from the momentary affinity towards the fiber, and in great afiinity dyeing systems, for instance, cationic dyeing stuffs and polyac'rylonitrile fibers, temperature differences of 1C mean absorption velocity differences of the 30 percent order, what causes these dyeing systems to be extraordinarily sensible to temperature variations.
  • this device is made up by an autoclave container, consequently it is provided with a tight look, containing the treatment bath, and comprises a volumetric reciprocating mechanism impelling said treatment bath from a chamber which communicates with the drilled supports or material carriers which carry the materials to be treated, so that the reciprocating movement of said mechanism impels a portion of the treatment bath during the upward stroke as well as during the downward stroke and compels it to flow through the textile matter in the one and opposite direction, whereby at the same time a separation between the two cited chambers is being established, what is the reason why the amount of the treatment bath flowing through the textile matter from its outside towards the inside of same finds itself confined independently from the total treatment bath volume which does not flow through it; this separation allows to independently handle each one of the portions into which is divided the total bath volume, in order to heat or cool them or add products to them; for this purpose the above cited chambers of the autoclave itself are provided with independently controllable heat exchangers as well as with the appropiate means for the introduction of additional products
  • the active organ of this treatment bath impelling mechanism may consist of a piston, membrane pump or radial rotary pump or any other contrivance with a reciprocating movement capable of acting in its two opposite strokes.
  • FIG. 1 is a diagram explaining the operating conditions of the usual autoclaves, where the circulation of the treatment bath is obtained by means of a pump.
  • FIG. 2 is a diagram similar to above, but the impelling of the treatment bath is made by a volumetric mechanism according to the invention.
  • FIG. 3 is a sketch showing a lengthwise section through a textile package showing the flow of the fluid through same.
  • FIG. 4 is a plan view corresponding to the foregoing figure.
  • FIG. 5 is a diagram showing the variations of the concentration of the product affine to the fabric according to the distinct zones of the packet, as a function of time, which take place in the treatments by means of the usual devices.
  • FIG. 6 is a diagram similar to the foregoing one, cor responding to the treatment by means of the device which is the subject of this invention.
  • FIG. 7 is a schematic cutaway of an embodiment of the device which is the subject of this application, in
  • FIGS. 8 and 9 are views similar to that of FIG. 7, which show two variants in which different typed of the treatment bath impelling mechanism are used.
  • FIGS. 10, 11 and 12 show the same number of variants of the device, each one provided with the treatment bath impelling mechanism as shown in FIGS. 7, 8 and 9, but this mechanism being located outside the autoclave.
  • this device which is the subject of this invention, lies in that itis provided with a volumetric device for the propulsion of the treatment bath through the textile packet, this device having a reciprocating movement, the features of which make it essentially different, both in regard to construction and to operation, from the known autoclaves in which the propulsion of the treatment bath is made by means of a pump or screw, whereby the difference of operation is to be seen from the diagrams shown in FIGS. 1 and 2.
  • each textile packet has its own fluodynamic characteristics so that when a liquid passes through it it offers a resistance to the passage of the same which depends on the permeability and flow per unit time which passes through it, these characteristics being connected with each other by an ex ponential function; in said FIG. 1 are shown the curves E and E corresponding to two textile packets of different permeability.
  • the operating point of the treatment bath impelling pump is determined by the intersection of the curve M with that of the corresponding textile packet, i.e., by the points A, and A for thetextile packets E, and E, and they determine the flow of liquid per unit time Q and Q respectively, which passes through the textile matter.
  • the flow of liquid per unit time depends 'on the pump type used and on the features of the textile packet.
  • the value of the-pressure depends on the resistance offered by the textile packet to the passage of the liquor in the way shown in FIG. 2,
  • the working pressures will be P and P respectively, for a determined flow of liquor per unit time Q, the pressures depend on the nature of the textile packets but noton the features of the treatment bath impelling mechanism.
  • this variation may be obtained by speeding up or slowing down the movement of the reciprocating mechanism, resulting, then, the flows per unit time Q and Q0, respectively, in this event the textile packet will be subjected to different pressures.
  • This possibility also means an advantage over the propulsion of the treatment bath by .means of a pump, for one is in the position to vary the flow per unit time for a determined textile packet, which is not so easily possible when the impelling mechanism is a pump.
  • the consequence of the constructive mode and of the operation of the reciprocating mechanism is the possibility to change, using a high frequency of the piston strokes, the direction of flow of the solution through the textile packet.
  • the possibility to quickly vary the direction of flow is of the highest importance in order to obtain a uniform dyeing of the inner and outer layers of a textile packet treated with circulating solutions flowing through it; this is based on the follow-
  • a textile packet such as shown in FIGS. 3 and 4
  • a treatment in which affinity effects between the fabric and the component products of the treatment solution (such as dyeing stuffs, chemical products, etc.) are involved, selective absorption of the product effects are produced in the measure the treat ment passes through the fabric.
  • the reversal may be done up to 20 four times per minute what means from 48 to times as much as in the present machines, and this makes that its treatment levelling possibilities are highly superior for the distribution of the product in the inner and outer zone is made without accumulations whilst the presently used time spans for these processes may be shortened; part of these processes are used to obtain a regularization of the accumulation of the product after its being deposited on the textile fabric.
  • the device which is the subject of the present invention and is shown in FIG. 7, having the above mentioned principles of irnpelling the treatment bath through the fabric altematingly in the one or other direction, comprises an autoclave container 1 provided with the conduits 2 and 3 with their corresponding valves 4 and 5 for the inlet and outlet, respectively, of the treatment bath, as well as a lid 6 endowed with a self sealing closing means and of a scavenger pipe 8 and a safety valve 9.
