Definitions

  • ABSTRACT Fibrous materials are continuously heat-treated under pressure by passage through a heat-treating chamber filled with a pressurized heating fluid and provided with at least a pair of symmetrical sealing chambers which are located at the inlet part and the outlet part of the heat-treating chamber.
  • Sealing fluid is introduced into the sealing chambers through pipes for in-: troducing the sealing fluid; and ejected from the clearances A and A toward the outside of the heat-treating chamber, while applying a static pressure to the atmosphere around the fibrous materials passing through the slits formed in the central part of the inlet and outlet of the heat-treating chamber. Leakage of the pressurized heating fluid from the heat-treating chamber can bethereby prevented, and the fibrous materials can be heat-treated without any damages.
  • This invention relates to an apparatus for continuously heat-treating various fibrous materials such as tows, slivers, filaments, strand-like fiber bundles or fabric products such as knittings, etc. in a pressurized fluid thereby to give desired physical properties or characteristics to said fibrous materials or to treat said fibrous materials.
  • the present invention relates to an apparatus for continuously heat-treating the fibrous materials under pressure in a heating fluid such as heating steam above atmospheric pressure, or various vapors or gases above atmospheric pressure, or various treating liquids in a pressurized state above atmospheric pressure, or the like to improve the quality of the fibrous materials.

Therefore, there is no problem relating to apparatus when the heat-treatment is carried out batchwise, for example, by means of an autoclave, etc., but, in an apparatus for continuously heat-treating fibrous materials by passing them through a pressurized fluid, it is necessary to cause a smooth passage of the fibrous materials through the inlet partand theoutlet part for the fibrous materialsfand further not to allow the pressure in the treating chamber to leak out of the inlet thereof. and the outlet part

  • the clearance B between the sealing plates 6 and 6', and the clearance B of the blank flange 5 musthave such widths and distances that the fibrous materials may not be damaged by the friction, but there takes place a leakage of the internal pressure, if the clearances are too large. That is, these clearances depend upon the sizes of the fibrous materials to be treated.
  • the directions of the sealing plates 6 and 6 are made symmetrical so that the clearances A and A may be directed towards the heat-treating chamber 2.
  • the direction in such a way that the clearances A and A may be directed symmetrically towards the outside of the heat treating chamber 2, or in parallel in the same direction, depending on heat-treatment.

  • the angles 0 and 0' between the sealing plates 6 and 6' and the blank flange 5 must not be more than to attain a good sealing efiect based on the pinching pressure of the sealing fluid and discharge the sealing fluid from the heat-treating chamber to the outside. If the angles are more than 60, the pinching pressure of the sealing fluid is lowered, and the sealing fluid is liable to enter into the heat-treating chamber 2.

  • the sealing fluid is a cheap one such as air
  • the fluid is fed by a blower. In such a case, there is no need of recovery and recycle of it.
  • a liquid having a high specific gravity usually has a good sealing effect, and particularly water is commercially advantageous, and its recyclic use is more economical.
  • the overflow chamber 4 is a compartment for collecting the fluid ejected through the clearances A and A'and owing to the restricted angles of ejection of the sealing fluid, the sealing fluid enters into the overflow chamber 4 outside the heat-treating chamber 2 from the sealing chambers 3 and 3 and never enters into the heat-treating chamber 2.

In the case of heat-treatment in a relaxed state, the speed of the withdrawing rollers 18 is made lower than the speed of the feeding rollers 17.

  • a further great feature of the present invention is that the sealing fluid never enters into the heat-treating chamber on account of the restricted angles of ejection of the nozzles, and is dis charged under the atmospheric pressure to the outside from the heat-treating chamber, and further can be recovered and recycled. Since there is no mixing of the pressurized heating fluid and the sealing fluid, it is possible to use different kinds of fluids. Even if the pressurized heating fluid is toxic or at a high temperature, it can be discharged from the overflow chamber 4 through the discharge pipe 10 and further recovered therethrough, and thus the present apparatus is quite distinguished in safety and sanitary protection. Furthermore, since the sealing fluid is recovered and recyled under the atmospheric pressure, the storage tank 11 may not be of a pressure-resistant construction.
  • a sealing can be attained by making the pinching pressure due to the static pressure of the sealing fluid-equal to the pressure of the heating medium in the heat-treating chamber.
  • the present apparatus has such advantages that various fibrous materials can be continuously heat-treated at a high speed without any leakage of the pressurized heating medium from the heattreating chamber to the outside and any damage to the fibrous materials, based on quite novel principle.
