Definitions

  • This invention relates to textile treating apparatus and more particularly to an apparatus for conditioning a tow of filamentary material formed from a synthetic composition such as acrylonit-rile polymers or the like with a pressurized fluid such as steam.
  • these stretched filaments possess excellent physical properties when formed into yarn and, in turn, fabrics, they are prone to fibrillate or spilt ofi into fibrills when subjected to abrasion. This fibrillation causes abraded portions of the fabric to appear lighter in color than the remaining portion giving the illusion of wear. It is thought that the fibrillation results from the internally strained condition of the molecular structure of the filaments created during the stretching operation. It has been found that this fibrillation can be reduced or substantial-1y eliminated by heat-relaxing or annealing the tow and this annealing operation may be carried out by subjecting the tow to a high temperature medium capable of wetting the polymer structure.
  • the tow was processed in a batchtype operation which involved loading large quantities of tow material into autoclaves or similar pressure vessels wherein it was subjected to steam under pressure for an extended period of time while in a relaxed condition. It can be understood that such a batch-type annealing operation is time consuming and is generally expensive from the standpoint of both time and labor expended as well as the initial investment in the bulky apparatus required.
  • a primary object of this invention is to provide a new and novel apparatus for the treatment of textile material.
  • Another object of this invention is to provide such an apparatus for continuously annealing a tow of filamentary material formed from a synthetic composition such as acrylonitrile polymers and the like.
  • a further object of this invention is to provide a new and novel apparatus for treating continuous material with a pressurized fluid.
  • This invention further contemplates the provision of a new and novel apparatus for continuously conveying a filamentary tow of synthetic material formed from a composition such as acrylonitrile polymer and the like through a substantially sealed chamber containing steam at a relatively high temperature and pressure so that, while the tow is in the chamber in a relaxed condition, it is subjected to the steam and subsequently removed therefrom in an annealed condition.
  • a still further object of this invention is to provide a new and novel apparatus for continuously annealing a filamentary tow which eliminates any contamina tion or-physical deterioration of the tow during annealing to give an annealed product of relatively high quality.
  • Still another object of this invention is to provide a new and novel apparatus for annealing acrylic tow which is simple in construction, virtually eliminates any discharge of steam into the surrounding atmosphere, and which automatically performs an annealing operation in a highly efficient manner for prolonged periods of time without danger of breakdown.
  • the objects of the invention and other related objects are accomplished generally by providing a conditioning chamber of substantially sealed construction containing a pressurized fluid such as steam. Pressurized steam at a relatively high temperature and in a wet or saturated con-. dition is supplied to the chamber for carrying out a heatrelaxing or annealing operation on a tow of filamentary material formed from a synthetic composition such as acrylonitrile polymers or the like.
  • a pressurized fluid such as steam.
  • Pressurized steam at a relatively high temperature and in a wet or saturated con-. dition is supplied to the chamber for carrying out a heatrelaxing or annealing operation on a tow of filamentary material formed from a synthetic composition such as acrylonitrile polymers or the like.
  • feeding means are associated with the container which continuously move the filamentary material into the chamber where it is received by conveying means in the chamber interior.
  • Means are also associated with the chamber for removing the tow from the conveying means inside the chamber to the chamber exterior subsequent to the completion of the annealing operation.
  • FIGURE 1 is a diagrammatic view of an annealing apparatus constructed in accordance with the invention.
  • FIGURE 2 is a sectional view taken substantially along line 2-2 of FIGURE 1 in the direction of the arrows;
  • FIGURE 3 is a sectional view taken substantially along line 3--3 of FIGURE 1.
  • FIGURE 1 there is shown a material treating apparatus constructed in accordance with the invention which is utilized to treat continuously moving material with a fluid medium maintained at a relatively high pressure.
  • the apparatus of FIGURE 1 may be employed to treat any desired type of material with any suitable type of fiuid medium, it is particularly useful in the heatrelaxing or annealing of filamentary material composed of a synthetic composition such as acrylonitrile polymers and the like, and it is for carrying out such an operation that the apparatus of the invention will be described hereinafter.
  • a tow designated by the numeral 11 which is composed of a plurality of continuous filaments of acrylic material Which have been freshly formed and are in an internally strained condition as a result of a previously carried out molecular orientation-treatment such as stretching or the like.
  • a conditioning chamber 12 which may be of any suitable shape such as that shown in FIGURES l-3.
  • the chamber :12 contains an interior 13 which may be filled with a fluid medium such as steam for carrying out the tow annealing operation discussed above.
  • tow feeding means designated generally by the numeral 14 which are preferably positioned as shown in association with the upper or top wall 16 of chamber 12. More specifically, the towfeeding means 14 comprise a pair of cooperating continuous webs or belts 17, 18, each of which is mounted on a pair of driving rolls 19, 21. Each pair of rolls 19, 21 is arranged to be driven by any suitable means (not shown) or if desired one of the rolls may be driven with the other roll arranged as an idler. As shown in FIGURE 1, rolls 19, 21 are positioned on opposite sides of the chamber wall 16 with the belts 17, 18 extending through suitably spaced wall openings 22. In this manner, the belts 17, 18 may be driven to move the tow 11 in sandwiched relationship with the cooperating portions of the belts and feed the tow continuously into the interior 13 of the conditioning chamber 12.
  • any suitable pressure device such as a labyrinth seal or resilient sleeve designated generally by the numeral 23 is suitably positioned adjacent each of the wall openings 22.
  • the belts and the tow 11 may then move continuously through the openings 22 and the sealing devices 23 while the chamber 12 is maintained in a substantially sealed position.
  • the sealing device 23 is of the type disclosed and claimed in the copending patent applications of each of the present applicants, Serial No. 728,459, filed Apr. 14, 1958, by Robert C. Jackson and Serial No. 728,461, filed Apr. 14, 195 8 by- James P. Richeson.
  • a heatrelaxing or annealing step is often required to relieve internally strained filaments and to obtain a tow having commercially acceptable physical characteristics.
  • Such an annealing step is generally carried out by subjecting the filamentary tow to a heated fluid medium such as 4 saturated or wet steam under pressure while the tow is in a'substantially tension-free or relaxed condition.
  • Conveying means therefore, have been provided for positioning the tow 11 fed to the chamber interior 13 in a substantially relaxed condition while being subjected to treatment by steam.
  • a continuous belt 24 is disposed within the lower portion of the chamber interior 13 as shown in Figure 1 and is mounted on rolls '26, 27, 28, so that its upper portion is driven in the direction of arrow I.
  • the belt 24 is arranged to provide a continuously moving, horizontal surface 29 on which the tow is deposited as it gravitates or falls from the nip of the. rolls 21 in the .tow feeding means 14.
  • rolls 26, 27 are positioned within the interior 13 of chamber '12 and roll 28 is positioned on the exterior of the chamber so that the belt 24 moves through openings 31 in the side wall 32 of the chamber 12.
  • the belt 24 is positioned so as to cooperate with an upper belt 33 of relatively short length and form means, designated generally by the. numeral 30, for moving the annealed tow 11 out of the chamber 12.
  • the upper belt 33 is suitably mounted on rolls 34, 36 which are driven in any suitable manner so as to move the upper belt 33 at the same linear speed as the elongated lower belt 24.
  • roll 34 is mounted so as to cooperate with roll 27 and roll 36 with roll 28 whereby tow 11 is sandwiched between the overlying portions of the belts 24, 33 and conveyed to the exterior of the chamber 12 through the centrally arranged opening 31.
  • the wall openings 31 are provided with suitable sealing devices, designated generally by the numeral 37, which are preferably similar to those associated with the wall openings 22 so as to maintain the pressure in chamber 12 and prevent the leakage of steam through the wall openings 31.
  • the interior 13 of chamber 12 is supplied with steam in order to bring the tow 11 to an annealing temperature of between approximately to C. It has been found that a steam pressure between 35 to 50 pounds per square inch gives satisfactory results. Furthermore, it should be understood that the steam is preferably of low quality for facilitating the annealing treatment.
  • suitable inlet means have been provided in the chamber upper wall 16 such as a fitting 38 which, of course, is preferably provided with a check valve or a similar device to facilitate the admission of steam.
  • a screen 39 may also be positioned as shown. in FIGURE 1 by any suitable means on the inner surface of the inclined portion of wall 16 adjacent fitting 38.
  • the steam passing through fitting 38 into the chamber interior 13 is reduced to a relatively non-turbulent condition.
  • the tow 11 is continuously fed into the chamber interior 13 through the top wall 16 by means of belts 17, 18 so that it gravitates, as shown best in FIGURE 1, onto the moving upper surface 29 of belt 24.
  • the tow 11 distributes itself along the moving surface 29 as shown best in FIGURE 3, so that successive portions of its length are continuously maintained for a predetermined period of time in a sub stantially relaxed condition.
  • the steam flows through the fitting 38, it fills the chamber 13 so that the tow distributed along the belt surface 29 is heated and moistenedby the steam as the tow moves across the chamber interior in a relaxed condition on the belt 24.
  • the internally strained filaments of the tow are heat-relaxed and the tow is in a completely annealed condition as it enters the nip of the rolls 27, 34.
  • the tow is picked up by the rolls 27, 34, it is sandwiched between the belts 24, 33, as described above, and carried out of chamber 12 through the centrally arranged wall opening 31 and cooperating sealing device 37 so that it may be subsequently collected and further processed in any desired manner.
  • the rate at which the tow is deposited on the moving surface 29 of belt 24 is regulated by any suitable means responsive to the movement of the tow.
  • tow speed monitoring means such as photoelectric cells 41, 42, are suitably positioned within the chamber interior 13 so that their associated light sources (not shown) may be interrupted by the reach of tow between the rolls 21 and the upper surface 29 of belt 24 when the tow is underfed or overfed.
  • the cells 41, 42 may be arranged in any suitable manner to control the speed of the tow feeding means 14 or the tow removal means 30. In one arrangement, cell 41, when its light source is interrupted, acts to reduce the speed of belts 17, 18, and cell 42, when its beam is interrupted, to increase the speed of belts 17, 18.
  • Condensed steam in the chamber interior 13 may be removed by means such as an outlet fitting 43 (FIG. 1) in which a suitable steam trap may be positioned.
  • filamentary tow or any other similar material may be continuously subjected to a pressurized fluid medium such as the apparatus of the invention is particularly suitable for treating wet spun acrylic tow and permits such a tow to be efficiently heat-relaxed or annealed in a simple or easy manner.
  • the annealing operation is completely automatic and the novel construction of the invention permits control of the annealing conditions over a wide range in accordance with the type of tow processed.
  • the container through which the tow is passed is maintained in a sealed condition to not only eliminate a source of annoyance caused by continually leaking steam, but also to enable the annealing conditions within the chamber to be accurately maintained at a predetermined level.
  • the tow is smoothly and rapidly moved through the annealing chamber with a minimum of change in form so that contamination of the tow is prevented and an annealed tow of high quality emerges from the chamber at the completion of the operation.
  • Apparatus for treating a tow of filamentary material comprising, in combination, a conditioning chamber having a top wall and side wall, means for supplying pressurized steam to said chamber, a pair of endless belts having engaging spans for cooperating to receive the tow therebetween and feed said tow into the interior of said chamber through said top wall, pressure sealing means mounted on the top wall of said chamber adjacent to and in contact with said pair of cooperating belts, a horizontal ly disposed endless belt drivably positioned in said chainber and extending through the side wall thereof for receiving tow from said cooperating belts, said horizontally disposed belt being arranged to convey said tow through the interior of said chamber in a relaxed condition whereby said tow is subjected to said steam, an endless belt mounted on the chamber and having a span engaging a portion of said horizontally disposed belt for cooperating with said horizontally disposed belt to hold the tow therebetween and convey said tow through said chamber side wall, pressure sealing means mounted on said chamber side wall adjacent to and in contact with said horizontally disposed
