Definitions

  • This invention relates to a pressure sealing apparatus suitable for sealing a continuous high pressure processing chamber for bundles of fibers or yarns arranged in tow form so as not to leak pressurized medium to the outside atmosphere and also relates to a processing apparatus equipped with the same.
  • this invention relates to a pressure sealing apparatus used in introducing fibers to a high pressure processing chamber from the outside atmosphere or in taking out them from the former to the latter for the purpose of continuous processing of bundles of fibers or yarns in tow-form collected and arranged in parallel from a number of groups of filaments or yarns especially of artificial fibers or tows thereof (throughout in this specification these will be referred to simply as fibers"), the order and arrangement of which are prefixed by e.g. adhesive tapes, yarns, or threads at several points near both the ends of warped fibers, in such continuous processings carried out under a temperature higher than 100 C. and a pressure higher than 1 atm. in steam atmosphere as scouring, bleaching, dyeing carried out by a pad-steaming process, stretching, relaxation, annealing, heat treatment or the like.
  • a pressure sealing apparatus used in introducing fibers to a high pressure processing chamber from the outside atmosphere or in taking out them from the former to the latter for the purpose of continuous processing of bundles of fiber
  • the fibers are led through an inlet side small tubular passage into a processing chamber and taken out through an outlet side small tubular passage to the outside atmosphere without heating and then pressurized steam is introduced into the processing chamber while controlling the ratio of the total cross-sectional area of fibers to that of the small tubular passage (hereinafter referred to filling up ratio of fibers) by adjusting the opening degree of the valve or cock installed so as not to cause a large amount of the leakage of steam out of the chamber and after an appropriate temperature is attained and processing operation is started, the leakage of pressurized fiuid, particularly pressurized steam, at the outlet is apt to vary and increase gradually. This phenomenon is often observed particularly in case of processing of artificial fibers, because the fine structure of artificial fibers becomes more compact due to the heat applied, causing shrinkage of cross-sectional area and reduces the filling up ratio of fibers in said small tubular passage.
  • Such a pressure sealing may be useful when the pressurize'd fluid for processing is liquid, but it is impossible to realize effective pressure sealing with only one valve or cock attached to the small tubular passage in the abovementioned invention without injuring fibers when the pressure fluid is steam which has extremely low viscosity.
  • valves or cocks in multiple stages, successively along a small tubular passage by which the cross-sectional area of it can be controlled only at places where valves or cocks are inserted and a controlled amount of steam is vented to the atmosphere at each stage between valves or cocks to adjust the steam pressure at each stage.
  • An object of the present invention is to provide an apparatus to overcome the drawbacks of the apparatus of two preceding inventions above-mentioned. Such an object can be attained by the apparatus of the present invention.
  • the present invention consists in an apparatus for sealing a high pressure continuous processing chamber at its inlet or outlet, through which; fibers are introduced into said chamber from the outside atmosphere and taken out therefrom without receiving any damage, which comprises a small deformable tubular passage having a length sufficient to produce a desired pressure drop, made of practically elastic material, installed in a protecting pressure chamber and directly attached to the outlet or inlet of the processing chamber; the cross-sectional area of the small tubular passage being adjustable to such an extent that filling up ratio of fibers passing through the small tubular passage is maintained at a value between 25- 50% of the adjusted area of the small tubular passage by controlling, from the outside atmosphere, the gap of at least a set of two plates throughout their entire length which are placed along the small tubular passage so as to clamp it, whereby the leakage resistance of the pressurized fluid from the pressure processing chamber on both the ends is increased so as to keep the filling up ratio of fibers between 2550% by strengthening the clamping of the two plates at one time or decreased by loosening the clamping of the two plates
  • the present invention consists in, an apparatus equipped with at least one above-mentioned pressure sealing apparatus useful for such a processing as scouring, bleaching, dyeing, chemical treatment, stretching, relaxation, annealing, heat treatment or the like, all carried out under a high pressure and a high temperature.
  • the apparatus of the present invention is different from and more advantageous than that of US. Pat. No. 2,954,687 in the points that a small tubular passage used for pressure sealing is installed in a protecting pressure chamber and its cross-sectional area can be controlled almost throughout its entire length within said chamber by the operation carried out from the outside atmosphere even in the course of processing and more advantageous than that of US. Pat. No. 3,213,470 in the points that it does not require valves or cocks in multiple stages as is the case with the above-mentioned patent in which they are used for controlling the opening degree of each valve or cock equipment.
  • the present apparatus is diiferent from and advantageous over conventional apparatuses particularly when fibers are to be stretched under heating at a high temperature in the atmosphere of a high pressure steam.
  • the crosssectional area of the small tubular passage can be reduced gradually as explained later and pressurized steam must be passed to leak through a long range of constricted passageway where the filling up ratio of fibers is increased, the pressure in said small tube drops gradually and continuously and thus a high pressure is practically sealed ofl? without impairing fibers.
  • a small thin wall tube of phosphor bronze, steel, stainless steel or the like having an elliptic cross-section and easily deformable by pressing it in the direction of the short axis of the illipse of the crosssection due to its elasticity, and also a flexible tube made of spring wound up in a tubular form and covered with TFEP and the like.
  • the inside cross sectional area becomes smaller and thus the filling up ratio of fibers passing therethrough is increased.
  • FIG. 1 shows a birds eyeview of a pressure sealing apparatus of the present invention which is attached to a pressure processing chamber by means of flanges and through which fibers are led into or out of said pressure processing chamber.
  • FIG. 2 shows a longitudinal crosssection of said pressure sealing apparatus furnished at the inlet of the pressure processing chamber and
  • FIG. 2 shows a longitudinal cross-section of said pressure sealing apparatus furnished at the outlet of the pressure processing chamer.

  • an apparatus having a diverging guide pipe 4' shown in a protecting chamber 30, is a pressure sealing apparatus for the outlet side of the processing chamber through which fibers are guided to the outside atmosphere after high temperature, and high pressure processing
  • an apparatus having a converging guide pipe 4a shown partly in the outside of the protecting pressure chamber 30 is a pressure sealing apparatus for the inlet side of the pressure processing chamber 1, through which fibers are guided into the pressure processing chamber 1.
  • the converging guide pipe 4' is fixed to the right end of the small tube 3 and placed within the protecting pressure chamber 30, and the wider end of said guide pipe is jointed to the opening of the outlet wall of a processing pressure chamber 1.
  • a stafiing box 5, through which the small tube passes, is provided at the end of the protecting pressure chamber 30, toward the side of the outside atmosphere and serves to seal the protecting pressure chamber 30 from the outside atmosphere.
  • the converging guide is provided whose wider end opens to the outside atmosphere and narrower end pipe 4 is attached to the right end part of the small tube 3, as shown in FIG. 2.
  • the spread fibers which have been subjected to a preliminary treatment such as padding with a dyeing liquor in the outside atmosphere prior to the high temperature and high pressure processing as stated later, are converged in the converging guide pipe 4 as shown in FIG. 2, and introduced into the small tube 3 which forms the inlet Side principal sealing means.
  • the small tube 3 directly connected to the guide pipe 4 or 4 is held between two plates 6 and 7, as seen in FIG. 3.
  • the clamping with the two plates is carried out by pushing said two plates with one or more rods which exerts vertical force upon the plates.
  • Explanation will be given in case of two rods.
  • the end parts 10 and 11 of the two rods 8 and 9 which are movable upward and downward, are placed in respective sockets 12 and 13 fixed on the plate 6, similarly, the end parts of two rods 25 and 26 which are movable also upward and downward, are placed in respective sockets 12 and 13 fixed on the plate 7, and further each of these end parts of the rods is secured to the plates 6 or 7 by means of bolts 14 or 14 as seen in FIG. 3.
  • the plate 6 is so constructed that it takes parallel positions relative to the plate 7 and the small tube 3 is clamped between the two plates 6 and 7 throughout its entire length by the vertical movement of the rods.
  • the movement of rods can be carried out from the outside atmosphere by any one of various mechanism.
  • One embodiment will be illustrated by a case where two rods are shafts of two screw presses having respective chain wheels in order to exert uniform pushing force upon the plates.
  • a handle 15, and a chain wheel 18 are fixed to a rotatable bushing 17, having female thread on its inner wall 17, and the male thread 16 on a shaft 8 engages with the female thread of the bushing 17.
  • the shafts 8 and 9 move up and down concurrently with the revolution of the handle 15.
  • the shafts 8 and 9 pass through staffing boxes 23 and 24, respectively in order to prevent the leakage of a pressure medium from the protecting pressure chamber 30.
  • the branched pipes 32 and 33 as seen in FIG. I serve as inspecting holes from which the inside of the protecting chamber is accessible for setting or repairing and through which the two upper and lower plates are fixed to the shafts by means of bolts 14 and 14 as seen in FIG. 3.
  • the lower plate 7 when the lower plate 7 is to be fixed at a proper horizontal position, it is adjusted at such a position by moving it up or downward by revolving the shafts 25 and 26, followed by fixing air tightly, with lock-nuts 27 and 28 and packings, respectively as shown in FIG. 3. Thereafter the plate 7 is set by means of a bolt 14 to the shaft 25 or 26 through the above mentioned holes 32 and 33.
  • the plate 7 may not always be of a structure movable up and down. It may be possible to predetermine, for practical use, the position of the plate 7 lying at a short distance apart from and along the centerline of said small tube and set it by means of shafts 25 and 26 as abovementioned and thus the upper plate 6 alone is moved up or downward in order to adjust the gap between the plates 6 and 7.
  • Both the right and left ends of the plates 6 and 7 are made in such a slant form like a forward end of a ski as shown in FIG. 2 to attain a smooth conveying movement of fibers because abrupt contraction of the small tube can 6 be avoided and the passing of the fibers through the small tube 3 becomes easier.
  • the pressure within the small tube 3 is generally lower than that of the pressure in the protecting chamber 30. Accordingly, even when a thin TFEP tube is used as a small tube, its inside cross-sectional area is not reduced down to a certain limit, since fibers filling it, are passing through it.
  • the inside cross-sectional area of the small tube is controlled by clamping it between two plates as stated formerly.
  • the leakage of pressure fluid from the protecting pressure chamber can be prevented, by merely welding the outer wall of the converging guide pipe 4 to the opening of the protecting pressure chamber through which said guide pipe is inserted.
  • the temperature of fibers is usually equal to that of the outside atmosphere and is below C. even in case where there is a need for heating them, for instance, in case of padding of a dyeing liquor, and even when the filling up ratio of fibers in the small tube at the inlet side is lower than that at the outlet side, the leakage of pressure steam or the like scarcely occurs, or is extremely little, because direction of leaking fluid is diametrically opposite to the traveling direction of the fibers introduced and moreover, in case of steam heating, the heat of leaking steam is absorbed in the cold entering fibers and the condensate is carried away in the small tube together with the fibers in high speed operation.
  • the distance of gap between the two plates is controlled so as to increase the inside cross-sectional area of the small tube to such an extent that fibers may not be injured by abrassion and the leakage of the pressure fluid, such as steam, is as slight as possible.
  • the operation is almost the same with that in the inlet side in principle, but it is often necessary to recontrol the clamping grade of the small tube especially soon after the beginning of the normal operation in such a way that the gap between the two plates becomes narrower. It is, particularly, so in case of artificial of synthetic fibers whose cross-sectional area is liable to become smaller by the shrinkage during processing.
  • TFEP tube makes the slipping of fibers better, without fear of injury thereupon and also is preferable in the point of corrosion-resistance.
  • TFEP tube When a TFEP tube is connected to the narrower end of a converging guide pipe, it is preferable that one end of the tube is expanded at first by heating, before being inserting in the narrower end of the guide pipe and the inserted part is tied with wire tightly.
  • a pressure scaling in case of high pressure steam processing, requires a length of about cm. of the small tube per difference of one atm. between the pressure in the processing chamber and that of the outside atmosphere when the filling up ratio of fibers is in the range of -35%. Accordingly, when a pressure in the inside of the chamber is ten atm., it is suitable to use a small tube whose inside sectional area is controllable over a length of about one meter for carrying out the processing without causing leakage of steam and affording any harmful effect on fibers.
  • the filling up ratio is increased up to 40%, the necessary length of the small tube to be controlled becomes shorter and even a length of about cm. will be sulficient for the sealing of 10 kg./cm. steam. But, considering the possible change in thickness of fibers during pressing, it is practical to carry out the pressure sealing by using a long small tube having a filling up ratio of approximately 30%.
  • the heat of the leakage steam is absorbed in cold entering fibers, the temperature of which is thus elevated and the condensate is carried away with the fibers, hence the steam leakage scarcely occurs or is extremely little, even if the filling up ratio of fibers is low.
  • fibers are often injured owing to the violent leaking jet of steam particularly at the inlet, unless the small tube is immediately clamped tightly. In such cases, the small tube must be, quickly and without delay, clamped by rotating the handle 15 shown in FIGS. 1 and 2 after stopping the operation.
  • the apparatus of the present invention is effective when it is furnished to the outlet or the inlet or the boh of a high pressure processing chamber of any structure equipped with necessary feed-in and taking-out rollers, guide bars, turning rollers etc., where a continuous processing is carried out under a pressure for a necessary processing period of time. Further, the present apparatus can be applied for processing fibers in tow form having a thickness within a wide range of from about 20,000 to several million denier by properly selecting the size and length of the small tube.
  • EXAMPLE 1 A filament yarn of about 5,000 denier consisting of 600 filaments of 8-8.5 denier, having a tenacity of 3.5 g./d. and an elongation of 36%, solely made of pure polyacrylonitrile, was subjected to twisting of 10 times per meter after being treated with an oiling agent for stretching (a kind of surfactant) so as to pick up 0.7% by weight.
  • an oiling agent for stretching a kind of surfactant
  • One unit of the stretching equipment used was composed of a group of feed pinching rollers placed in front of the high pressure steam processing chamber; the processing chamber itself having the pressure sealing ap paratus of the present invention at both the inlet and outlet side and further several fixed bars installed near the inlet in zig zag arrangement in order to spread and flatten the tow introduced; a group of taking up pinching rollers, and a winder arranged in this order in series.
  • the tow already put together into 250,000 denier was jointed to the end of the guiding thread at the feeding side of the feeding pinching rollers and then pulled together with the thread by means of taking up pinching rollers.
  • the tow was gradually introduced into the processing chamber and came out of it.
  • the tow after passing through the inlet side pressure sealing apparatus, was spread and flattened by passing over the fixed bars installed in the processing chamber in zig-zag arrangement. During this period, before stretching was begun, the small tubes were still kept round on both the inlet and the outlet sides and the filling up ratio of tows in the small tubes was estimated to be about 39% by calculation.
  • the stretching of the tow started by introducing pres surized steam into the pressing chamber till the temperature in the chamber rose up to 120 C. under a saturated steam pressure and the stretching ratio was gradually raised by controlling both the speeds of the inlet side and outlet side pinching rollers till it reached up to 2.5 times stretching.
  • the stretching ratio was raised and became close to the predetermined ratio, the small tubes of the sealing apparatus on both the inlet and the outlet side were pressed by clamping two plates till the tubes became elliptic in order to decrease leaking steam.
  • 50 kg. of the stretched tow of about 100,000 denier was obtained by taking it up at a rate of about 12 meters per minute.
  • the once stretched tow was then subjected to relaxation and simultaneous annealing giving 20% contraction in length under a saturated steam pressure at 165 C. using the same unit of the equipment to get 125,000 denier tow, followed by re-stretching by 2 times the relaxed and annealed tow at 140 in the atmosphere of a saturated steam, using also the same unit of the equipment, excepting that a small TFEP tube of 6.5 mm. inside diameter and 0.5 mm. wall thickness was used in place of the previous one having the 9 mm. inside diameter and 0.5 mm. wall thickness in the pressure sealing apparatuses on both the inlet and outlet side.
  • over-all stretching by 4 times of the original tow could be carried out by two step stretching while putting in a relaxation annealing step between the two stretching steps.
  • the restretched tow was then divided into two warped yarns originally composed of and winded on two beams, respectively, each of which was separated successively into 25 original yarns in parallel by the guidance of the weft yarns which had been inserted at both the beginning and the terminating ends of the warped yarn by passing through a comb installed at one end of a spindle type twisting machine, while giving effective vibrations transversely to the whole yarns in order to disentangle the yarns which might have become out of order during the processing and each yarn was wound on a bobbin with simultaneous twisting up to 50 turns per meter.
  • the yarns thus obtained after cutting off both the end parts thereof which had been unevenly stretched during the processing, had a tenacity of lll2 g./d., elongation of 67% and thickness of l,200l,300 denier and were of superior quality as raw materials for producing carbonized yarns having high tenacity and high Youngs modulas after carbonizing.
  • EXAMPLE 2 To obtain a tow of 500,000 denier, an acrylic polymer, prepared from 95% by weight of acrylonitrile and 5% by weight of methyl methacrylate by redox-polymerization, was subjected to wet spinning using a dope containing 14% by weight of said polymer in 67% HNO aqueous solution and, using 33% HNO aqueous solution at 2 C. as a coagulating bath; complete washing with water, primary stretching 2.5 times the original length before stretching in a water bath maintained at 70 C.; secondary stretching 6 times the length before stretching in a water bath at about C.; tertiary stretching 8.5 times the original length in a bath of -98 C., and drying successively.
  • the tow thus obtained was introduced into a pipe autoclave of 160 mm. in diameter, 80 meters in total length, arranged in U-shape and maintained at 134 with saturated steam, through a pressure-sealing apparatus of the present invention.
  • a group of pinching rollers At a place 2 meters from its inlet opening in the inside of the autoclave, there was installed a group of pinching rollers by means of which the tow was pulled into the autoclave at a speed of 90 meters per minute and the tow travelled over two driven turning rollers of mm.
  • the tow was subjected to relation-annealing, allowing contraction of about 23% of its length during passing through the autoclave in 1 minute.
  • the filaments after subjected to this heat treatment, were homogeneous in their physicochemical properties, resistant to fibrilation, highly stabilized in dimension, and of superior practical value.
  • acrylic fibers prepared according to a wet-spinning process using an organic solvent such as dimethylformarnide, dimethylacetamide, dimethylsulfoxide or the like, or an inorganic solution such as concentrated solution of rhodanates or zinc-chloride as a solvent for the polymer could be treated after once dried up, affording superior effects as fibers.
  • EXAMPLE 3 A crimped polyester tow of 300,000 denier, packed in a box every 50 kg., and available in the market, was spread up to about 200 mm. wide and stretched by 13% till its crimps disappeared completely during the processing in a steam chamber maintained at 95 C.
  • the tow was introduced into a padding vessel of a dye-liquor containing 2 g./l. of a dispersing agent and then, the tow was squeezed by a mangle so as to pick up 38% by weight of the dye liquor, the concentration of which had been so adjusted that the squeezed tow might pick up 2% of dispersed dye Dianix red brown, 1% of Dianix blue RN and 0.4% of Dianix yellow Y-L (all made by Mitsubishi Kasei Co., Ltd.) by O.W.F.
  • the dye liquor was al- 1 l lowed to sufficiently permeate into the tow during the passage of the tow through the dye vessel and over zigzag bars equipped between the dyeing liquor vessel and the mangle in the padding apparatus, while calculated volume of the dye liquor carried away by picking up was continuously supplied into the vessel.
  • the tow was introduced into a high pressure steamer 45 meter long and 120 mm. in diameter, maintained at 160 C. by introducing saturated live steam into it, through a pressure sealing apparatus by pulling in with pinch rollers installed in the inside of said steamer close to the inlet opening, at a speed of 45 meter per minute.
  • the tow was evenly dyed in deep brown by absorbing almost completely the dyestuffs on fibers, when drawn out at a speed of 42 meter per minute from the steamer through an outlet side pressure sealing apparatus of the present invention, without contacting with drain in the bottom of the steamer, by means of taking up picking rollers installed in the outside atmosphere.
  • the outlet side pressure sealing apparatus was satisfactory, needless to say of the inlet side one, and the fibers of the tow was scarcely damaged, when the small tube of said apparatus was adjusted to become narrower so that only a slightest amount of steam leaks through it together with the leaving tow.
  • the dyed tow was passed through a reducing agent bath, and a soaping bath and dried after washing with water, whereby an evenly dyed tow having brilliant gloss was obtained.
  • a tow dyed evenly in deep blue was obtained by using the said apparatus as abovementioned, when the amount of picked up dyeing liquor on the tow was adjusted to be 5% Resorein blue FBL and 0.3% Amacron orange LS. by O.W:F., using 2 g./l. of :Resper TL as a dispersing agent.
