Description

1. The present invention relates to a method and a device for

  heat and humidity treatment of a textile product in the form of filaments, such as a yarn, filaments and ribbons of fibers (hereinafter called to simplify the textile product in the form of filaments) of a

  continuously and quickly by submitting the text product

  to treatments such as pre-treatment, fixing

and a tincture.

  It is known to subject a textile product in the form of filaments to treatments such as a pre-treatment, a

  fixing and dyeing before subjecting it to a

  secondary in order to manufacture products such

  than knitted and woven clothes.

  For example, a textile product in the form of a fila-

  elements extracted from a crossed coil, a coil or the like

  gue is impregnated with a coating treatment solution

  ment or immersion, and routed to a processing chamber

  heat in the open air. However, in this case, the method has certain limitations in the application of the treatment solution, in the duration of the treatment.

  thermal and other limitations, so that such a process

  dice does not allow rapid processing and manufacturing

serial.

  Another method consists in subjecting a 2. textile product in the form of filaments impregnated with a treatment solution to the outside of a high pressure vaporizer.

  wet heat treatment in a reaction chamber

  tion, that is to say a high pressure vaporizer, at a high temperature and pressure. However, in this case, as the textile product previously impregnated with the treatment solution must be strongly compressed during its introduction into the body of the vaporizer so as to

  decrease the amount of treatment solution that has adhered

  re to product, no wet heat treatment of ex-

  this quality cannot be achieved due to lack of

  treatment lution. In addition, since a waterproof-

  ity air has been adopted in the prior art to seal a high pressure vaporizer, it is difficult to

  keep this body well exposed to moist heat,

ie saturated steam.

  In view of the above, the present invention

  relates to a process and a device for

  the moist heat of a textile product in the form of

  filaments in a continuous and rapid manner, with a pro-

  high ductivity in a high pressure vaporizer by subjecting it to treatments such as pre-treatment,

  fixing and dyeing (hereinafter simply treated

  is lying). The essential points of the process of the present invention are that a textile product in the form of filaments continuously introduced into the body of a high pressure vaporizer in which humid heat is maintained,

  high temperature and pressure, is impregnated con-

  venable from a treatment solution and is treated there with moist heat, and the textile product thus treated is subjected to a fixing process by cooling

  near the outlet of the vaporizer body and ex-

trait of it.

  The present invention will be well understood during

  the following description made in conjunction with the drawing

  which represents a device for the wet heat treatment of a textile product in the form of filaments in

a high pressure sprayer.

  relative to each other and close to each other. The con-

  voyeurs consist of a net made of wire, fiberglass, fiber called teflon and the like, but a sheet

  porous metal and a plurality of endless strings available

  laid in parallel can be used.

  The reference 3 represents a crimping device making it possible to place a textile product 4 in the form of filaments in the crimped state on the conveyor 1. The textile product is transported in the crimped state as soon as it has

  been put on the conveyor 1, being held by the con-

  upper voyeur 2, from left to right of the figure

  re, thanks to the movement of the two conveyors.

  vaporizer 5 respectively have a sealing mechanism

  side 8 on the inlet side and a sealing mechanism 9 on the outlet side allowing the passage of textile products in the form of filaments and conveyors with maintenance inside the body of the vaporizer of moist heat at

  a temperature of about 1600C and a high pressure.

  The mechanism 8 comprises a pair of rubber sealing rollers pressed against each other 81, a tank of liquid 82 between the rollers 81 and the orifice

  input 6, a pair of compression rollers 83 allows

  both to control the liquid content of tex-

  tiles coming out of the tank 82, a supply line 84

  with the rubber rollers 81, so that first

  cool the rollers 81, then allow the treatment solution to flow into the tank 82. On the other hand, the sealing mechanism 9, on the outlet side, comprises a pair of pressed rubber sealing rollers 9

  against each other in the same way as for the mechanic

  me on the inlet side, a slow cooling tank 92, a pipe 93 for supplying the tank 9 with a liquid

  cooling which is also used for washing from outside

  laughter of the vaporizer, and a guide wall 94 allowing the coolant supplied by the pipe 93 to the tank 92 to come into contact with the rubber sealing rollers 91 so as to first cool the rollers

  91 then allow the coolant to circulate

dissement in the tank 92

  Reference 10 represents guide rolls.

  dage mounted in the body 51 of the vaporizer, the reference 11 a liquid tank located outside the body 51, the reference 12 a pump for supplying the treatment solution of the tank II successively to the tank 82

  located inside the body 51 of the vaporizer, the reference

  ce 13 a washing tank for washing the textile product leaving the body 51 of the vaporizer, the reference 14

  a dryer, and reference 15 of the supply lines

  tion of the vaporizer body, The operation of the previous device will

  now described. First, the interior of the body 51 of the va-

  porizer is kept filled with saturated steam at high pressure having an appropriate temperature up to OC; a prescribed treatment solution (for example, a caustic alkali solution for the pretreatment and a dye solution for the dye) is supplied to the tank 82 through the supply line 84, and fresh water is introduced through line 93 in the tank of

slow cooling 92.

  Then a textile product 4 in the form of a fila-

  5.ments is curled by device 3 and placed after

  on the conveyor 1. The crimped textile product 4 is compressed

  down for a short period of time by the con-

  voyeur 2 and transported from left to right of the figure. The textile product is introduced, through the mechanism 8, into the body 51 of the vaporizer, then immediately immersed with the conveyors 1 and 2 in the

  solution for treating tank 82 so as to imprint

  impregnate with the treatment solution. The textile product

  impregnated with the treatment solution is slightly

  awarded by the rollers 83 so as to control the content of treatment solution, and then is subjected to steam in the body 51 of the vaporizer so as to carry out the desired treatment, such as dyeing, pretreatment,

and weight reduction.

  The textile product, after having been subjected to sufficient steam, is cooled slowly by passing through the slow cooling tank 92, extracted from the body 51 of the vaporizer, washed in the tank 13, dried in the dryer

  15, and wound on a spool or a crossed spool.

  As described above, the present

  The invention impregnates a textile product in the form of filaments with a treatment solution in

  the liquid tank 82 arranged in the body 51 of the vapori-

  so that the textile product can be exposed to steam while incorporating a sufficient quantity of treatment solution, which allows treatment with

  uniform and efficient moist heat. Furthermore, being

  born that the textile product is then effectively fixed

  by slow cooling in the tank 92 (at a temperature

  ture of about 500C) just before being extracted from the body 51 of the vaporizer, its feel and its swelling are not affected, even when it is compressed during its passage through the rubber rollers 91 'which makes it possible to obtain

  a high quality product. The present invention pre-

  feels the other advantage of avoiding the use of high pressure air through the use of the treatment solution

  and slow coolant as sealing media

  6.bodyness of the vaporizer body, so that one can

  maintain inside the body 51 of the vaporizer a

  their high quality wet (saturated steam) and submit

  the product steamed effectively and excellently.

  The present invention is not limited to the exemplary embodiments which have just been described, it is on the contrary subject to modifications and variants.

  which will appear to those skilled in the art.
