Claims.
This invention relates to the treatment of textile fabrics with a heated,fluid such as steam, or with a hot mixture'of steam and another gas or vapor such as air, for the purpose of thorough- 1y heating said fabric and raising its temperature to a suitable degree. The invention relates to certain new and improved apparatus suitable for treating textile fabrics with a heated fluid, more particularly with a mixture of steam and air, so constructed as to permit this treatment to be carried out in an efllcient and convenient manner. This pplication is, in part, a continuation of my copending patent application Serial No. 394,646, filed May 22, 1941, now Patent No. 2,304,474.
Textile fabrics, either in the web form or coiled into a generally rope-shaped form, are frequently subjected in various textile finishing processes to the action of various heated fluids. For ex ample, in the treatment of textile goods of vegetable origin with alkaline scouring liquids, or with peroxide bleaching solutions, or with both agents,
suchas by methods disclosed in the Campbell and Fennell Patent 2,267,718, it is essential that the textile material be subjected to the action of a heated fluid such as steam. This may be readily accomplished either by passing the textile material in web form through a tube filled with steam or with a hot steam-air mixture, or by loosely forming the web of textile fabric into rope form and passing this rope through the chamber containing the hot-fluid. Since the success of various subsequent operations employed for treatment of the textile fabric frequently depends on the thoroughness of heating in this preliminary treatment step, I have devised a new and improved apparatus which can be more efliciently employed for heating textile fabric, either in web orrope form, by means of a hot fluid, particularly a steam-air mixture.
Accordingly, it is one of the objects of this invention to develop a new and improved steam tube construction which permits readier and more efficient treatment of textile fabrics with a heatair. Where steam under pressure and at a high temperature is available it is frequently essential not only to reduce the pressure to atmospheric or near atmospheric, but; also to mix with the main body of steam air in sufiicient amount to lower the steam temperature to one below the atmospheric boiling point. Thus, by suitably introducing a stream of air into the main body of air-steam mixture.
sible to reduce its temperature from 212 F. to 200 F. or lower, and to regulate the amount of mixed fluid supplied at the desired temperature. Accordingly, another object of my invention is to develop a new and improved steaming tube construction, including expansion piping, which permits the high pressure steam to expand to or V nearly to atmospheric pressure, and an air induc tion tube wherebysteam at high pressure may have its temperature reduced below 212 F. by suitably admixing therewith a sufiicient amount of air at room temperature. These steps are carried out in my improved apparatus before the mixture is brought into contact with the textile fabric to be heated.
Still other objects of this invention involve the improvement of the heating tubes which are now available by providing a construction which permits a longer period of contact between the textile fabric and the heated fluid, which heated fluid in my improved apparatus constitutes a mixture of steam and air. A further object is the provision of a heating tube so arranged as to permit ready access for inspection and for threadin through the rope orweb of textile material, An additional object of my invention is the improvement of presently available heating tubes by providing for a powerful jet of a steam-air mixture, this let being permitted to act upon the textile fabric which is traveling in a direction countercurrent to the direction of flow of the steam-air mixture. In this way the jet serves not only to drive out air present in the interstices of the textile fabric, but also to secure thorough impregnation and consequent heating thereof by the hot steam-air mixture. Other objects of my invention will be apparent from'the ensuing disclosure of certain preferred embodiments-thereof.
My invention may be more completely described with reference to the annexed drawing wherein Fig. 1 ma vertical cross-sectional view, some parts being shown in elevation, of my improved heating tube construction and accessory steam expansion and air induction elements.
This view shows the fabric in rope form passing through the U-shaped heating tube am being therein subjected to the action of the heated Fig. 2 is a plan view showing the and driving mechanism at the right hand portion of Fig. 1. Fig. 3 is a cross-sectional view taken on the line 3-3 of Fig. 1. Fig. 4 is a cross-sectional view showing in detail an element of the steam at or near atmospheric pressure, 'it is posing more fully described as the conduit and disupper pulleys tributor for supplying the hot steam-air mixture to the textile fabric. Fig. 5 is a cross-sectional view taken on the line 5-5 of Fig. 4. Fig. 6 is a cross-sectional view taken on the line 65 of Fig. 1.
My improved device consists generally of two vertical tubular members H and I2 through which the cloth is passed and wherein it is subjected to the action of the heated fluid. Above tube 12 there is provided pulley l4, while above tube H there is provided pulley l5, the fabric passing over these pulleys on its way into and out of the vertically-extending tubes. Below tubes H and I2 there is provided a pulley IS. The textile material IS, in web or rope form, travels in the general direction shown by the arrows, entering at the upper right in Fig. 1, passing over pulley l4 down through vertical tube l2, around pulley l6, up through vertical tube I I, over pulley l5, and thence out of the apparatus.
Around pulley l4 there is provided an enlarged box member 20 which is provided with a vent pipe 22 opening to the atmosphere. This pipe is provided with damper 24 which can be adjusted in a number of positions for controlling the venting.
bailie member 52, this outlet serving to discharge condensate outside the vertical tube II as shown in Figure 1.
As shown at the upper left hand end of Fig. 1.
- the steam-air mixture is supplied to distribution member 56 from the high pressure steam line 8|.
- The steam under pressure and at a high tempera- In a wall of the enlarged chamber 29 there is provided an opening 26 for the passage of the textile material l8. Within chamber there is positioned a supporting plate 28, attached as by welding to the lower wall of member 29, and in this plate another opening 30 is provided for the passage of and guidance of the rope or web of textile material being treated. As shown, the pivoted plate member 32 may be opened to permit ready access to the pulley l4.
Around pulley I5 is provided another enlarged chamber or box member 38, provided with a pivoted plate or door member 38. This plate may be opened to permit access to the pulley 15.
Below vertical tubes II and I2 there is provided the lower enlarged portion surrounding pulley I 6. This member is constructed with a foraminous false bottom 42 through which condensed steam may pass to discharge pipe 44 but on which lint or other foreign matter which may be present is retained. Access to the pulley l9 and to the gauze 42 is afforded through the opening in the member 40 covered by door 48. The
pipe for removing condensate 44 is constructed in U-form so as to provide a liquid seal at the bottom of the apparatus, thereby preventing escape of steam through this pipe.
In the vertical tube II there is provided the member supplying and distributing the hot ture in this line flows through two conduits 83 and 85, these conduits being branched from the high pressure steam main 8 i. The steam in conduit 83 passes through valve 81 and into enlarged expansion piping 89 wherein it expands to substantially atmospheric pressure, at the same time its temperature being lowered. That portion of the steam circulated into conduit 85 serves primarily for air aspirating or induction purposes, and may constitute only a very small part of the entire amount supplied to steam distribution member 56, the principal supply coming through conduit 89. In conduit 85 the steam passes through reducing valve 9| wherein its pressure is reduced to a gage pressure slightly above ,atmospheric, from 15 to 25 lbs. and then into that portion of the conduit designated by the numeral 93. The pressure at this point is indicated on gage 94. Valve 95 can be opened in amount sufiicient to control the supply of steam to the discharge nozzle 91, positioned within enlarged portion 99 of expansion piping conduit 89. As shown, there is provided a conduit 10l open to the atmosphere and controlled by valve I03, thisconduit being in communication with enlarged portion 99 of expansion piping conduit 89 surrounding thesteam discharge nozzle 91. The steam jet issuing from nozzle 9! acts as an injector serving to draw in atmospheric air through air inlet conduit llll, the amount'inducted at this point being controlled by valve I03. This atmospheric air is at room temperature and, when admixed with the expanded steam in enlarged portion 99 of expansion piping 89, the temperature steam-air mixture, this element being shown tion member 58 and in general alignment with vertical tube I l is the apertured tube 54, through the apertures of which the steam-air mixture passes into the vertical tube I l. The baille members 58 serve to distribute the heated fluiduniformly over the entire length of the apertured distribution pipes 54. To permit the escape of condensed-steam there is provided outlet 69 be ow of the resulting steam-air mixture is reduced below 212 F. This steam-air mixture is then supplied through conduit I01 as the heated fluid to distribution member 55 as previously described, thus bringing the heating medium into contact with the textile fabric to be heated.
In operation, the textile material enters in either web or rope form through eyes 26 and 30,
passes over pulley l4, down through vertical tube i2, over pulley l6, up through vertical tube ll, through the area within the apertured distribution tube 54, and out of the apparatus over pulley IS. The steam-air mixture supplied through conduit 50 is distributed by baille 52 throughout the entire extent of the member 55, and passing through the apertures in the apertured distribution tube 54, comes into contact with the textile material. The steam-air mixture entering through the apertures in distribution member 54'passes downwardly through pipe ll, its upward travel being restricted by the partial closure lip 55, forming an eye through which thei'abric being treated passes. After passing downwardly through the vertical tube II, the heated fluid then passes upwardly through vertical tube I2, thus coming into contact and impregnating and heating the textile material during the entire period that it is within the apparatus. Excess uncondensed steam is permitted to escapeto the atmosphere after emerging from the upper part of the vertical tube l2 through the damper controlled vent discharge 22. Condensed steam is drawn oif through the outlet pipe 44, constructed in U-form as previously explained to provide for a sealing trap at the bottom of the apparatus.
It will be noticed that the direction of flow of the steam-air mixture serving as heating fluid is generally counter-current to the direction of travel of the textile web or rope. This is an important feature of my arrangement, and, combined with the impinging of the steam-air mixture directly on the textile fabric, thus driving out air present in the interstices therein and replacing it by heated medium (thereby serving to effect thorough impregnation) results in much more satisfactory heating than heretofore possible. Moreover, any air entering with the web or rope 'of fabric at 26 is discharged through the flue 22, its removal from the apparatus at this point being aided by the stream of steam escaping therethrough, in which stream of steam the air is entrained and removed. By providing expansion piping and means by which air at a lower temperature may be introduced or injected into the steam to form a steam-air heating mixture I can secure any temperature desired, either above or below the atmospheric boiling point of water (212 F.), and can control the supply of heated'fluid in various volumes as desired.
Access to the pulleys I 4, l and I6 for inspection and for the purpose of threading the textile material through the apparatus is provided by pivoted door members 32 and 38 and through the pivoted door 48 in the lower enlarged compartment 40. Pulleys l4 and I5 are driven from sprocket 66, drive shaft 68, sprocket I0, chain or sprocket belt 12, sprocket I4, and drive shaft I5, serving to drive pulley ll, as shown more fully in Fig. 2. The lower pulley I 6 on shaft I1 is an idler pulley.
It should be understood that various changes and modifications might be made in the apparatus as described which would nevertheless come within the purview of my invention. Its scope is therefore not to be restricted to details intended merely as illustrative of the preferred embodiment thereof herein described, except as necessitated by the appended claims.
