Definitions

  • This invention relates to a continuously operating system for scouring cloth, knitted fabrics, and the like, which system is suitable for use at various processing steps thereof, such as preparation, mercerization, scouring after dyeing and after printing, as well as in the course of final finishing.
  • each single scouring system is only suitable for treating one product type.
  • scouring requirements other than those for which the machine has been intended no fully satisfactory results can be achieved; actually, there is no such thing as a really universal scouring tank or system, that is such as to ensure optimal results regardless of the type of woven or knitted fabric being handled, whether in the flat or tubular form.
  • the fabric should be let free, to a certain extent, to give and deform, as due to internal stresses or in order to accommodate exceptional and unforeseen treatment conditions.
  • the fabric is restrained rigidly in its movement, as where driven throughout its length, the likely result would be a failure in the scouring system due to the very high tensions induced in the fabric.
  • This invention sets out to provide a novel continuously operating scouring system which can satisfactorily obviate the drawbacks mentioned above.
  • the continuous operation scouring system according to this invention is.of a truly universal type, i.e. capable of operating in an optimum manner with any types of fabrics, knitted fabrics, etc., whether in the open or flat condition or tubular condition.
  • the scouring system of this invention is designed and constructed such as to impart no tension on the fabric being scoured, while allowing the fabric to develop any spontaneous shape changes.
  • the continuous scouring system of this invention affords a particularly efficient and active scouring action, and in particular a more effective scouring action than that provided by currently available systems.
  • a continuously operating system for scouring cloth, knitted fabrics, and the like which comprises an enclosure or housing containing a plurality of guiding rollers, means for carrying out a scouring process within said enclosure or housing, and means for driving a number of said roller plurality, characterized in that said rollers are parallel and closely adjacent each other such as to oblige a fabric, or the like, to a path of substantially continuous contact with said roller plurality, and that said scouring means are arranged, relative to said roller plurality and said path, such as to be active on both sides of said fabric, or the like.
  • the scouring system of this invention comprises an enclosure or housing 1 which extends tower-like in a vertical direction, and wherethrough is passed a continuous web of woven cloth, knitted fabric, or the like, either in the flat open or tubular condition, which will be termed hereinafter "fabric" for simplicity and designated with the reference numeral 2.
  • the fabric 2 is inserted into the system at the base of the housing 1 and led out of the system at the top of the housing.
  • the housing, or enclosure, 1 is provided along its vertical extension with a series of inspection rings 1a and a series of flow directing baffles 1b which can be tilted outwards to gain full access to the housing inside.
  • the housing supports rotatably a plurality of main rollers 3 of large size, and a plurality of squeezing rollers 4 of smaller dimensions.
  • the main rollers 3 are parallel to one another and stacked to precisely overlie each other at positions of close proximity.
  • the squeezing rollers 4 are also parallel to one another and to the main rollers 3, as well as vertically aligned to each other.
  • Each squeezing roller 4 is closely adjacent and at a forced contact position with a main roller 3. All of the cited rollers 3 and 4 serve a fabric guiding function.
  • the fabric 2 after running over a considerable portion of a main roller 3, engages with a squeezing roller 4, from which it is redirected to a main roller 3 overlying the former.
  • the fabric follows each time the same path, and in practice a series of loops or bights, while in contact with the rollers 3 and 4 such as to leave free but extremely reduced portions of the fabric, which appear quite negligible compared to the fabric extent passed around the rollers.
  • the fabric 2 follows a true transfer path in the vertical direction, whereas on the opposite side of the housing 1, the right side in Figure 1; the fabric 2 is simply deflected to said one side.
  • scouring means adapted for actuating the of the fabric 2, which means advantageously operate on both sides of the fabric.
  • These scouring means subject the fabric to three discrete types of scouring action, which are mutually coordinated such that the various scouring actions enhance one another.
  • a first type of scouring action is carried out in counterflow adjacent that side of the housing 1 whereat the fabric 2 follows practically a vertical travel path, that is, in Figure 1, at the left-hand side of the housing 1. More specifically, at the top of the housing 1, there are arranged main nozzles 5 operative to spray tap water, which after sweeping the fabric 2 directly while the latter leaves the scouring system flows downwards to sweep the fabric around the main rollers 3.
  • the flow directing baffles 1] 2 are arranged adjacent the main rollers 3, thereby favoring the counterflow scouring action.
  • the cascading water flows downwardly into a collecting tank 6 at the bottom of the housing 1, where an overflow device 7 discharges it gradually.
  • the second scouring action which consists of a forced scouring action effected by spraying the fabric 2 directly through spray nozzles 8 which are oriented to sweep the fabric 2 immediately ahead of where it winds over each main roller 3.
  • the second scouring step or forced spraying scouring action is effected by a centrifugal pump 9 which cycles back into the housing 1 the water collected at the bottom of the collecting tank 6, after the same has been filtered through a filtering device 10.
  • the centrifugal pump 9 feeds a vertical conduit 11 from which there extend, in parallel relationship, branching channels 12 which feed the spray nozzles 8 directly.
  • the spray nozzles 8 are arranged to sweep that side of the fabric 2 which, during the preceding scouring step in counterflow, contacted the main rollers 3 directly.
  • the nozzles 8 are on that side of the housing 1 which is opposite the one involved in the counterflow scouring action by cascading water supplied from the main nozzles 5.
  • These rollers do not serve solely for deflecting the fabric 2 toward that side of the main rollers 3 whereat the counterflow scouring occurs, but also to squeeze the fabric 2 prior to each series of scouring steps to eject the liquid accumulated therein.
  • the squeezing rollers 4 are biased by elastic means acting on their ends and comprising, for example, either springs or calibrated pressure pneumatic springs, against the main rollers 3, where the fabric just reverses its ascending motion.
  • the scouring action by squeezing enhances the other scouring actions in that not only an effective alternation of absorptions and squeezes is created in the fabric, but also because by freeing the fabric of the water absorbed during the preceding scouring steps and partially drying it, the subsequent scouring actions are made more effective.
  • Figures 2 to 5 show, inter alia, how the main rollers 3 are driven, around which extends a major portion of the travel path of the fabric 2.
  • all the main rollers 3 are rotatively driven, i.e. contribute all to entraining the fabric wound around them.
  • the driving action of the main rollers 3 is not of a rigid type, and can be overcome, both in acceleration and deceleration, by any tensions generated in the fabric, which tensions will in practice oblige each main roller 3 to turn at the most appropriate speed.
  • Figure 2 shows the use of a double chain 14 and above all the fact that, as shown also in Figures 3 and 4, direct contact with the wheel 13 occurs at the rotatable bushings 15 of the chain 14 rather than at the links 16.
  • This sliding engagement gradually converts to a forced driving engagement as the chain 14 is pulled tight to increase the friction between the pins 17, rigid with the links 16, and bushings 15 encompassing the pins 17.
  • Figure 4 shows, again in an exaggerated manner, the situation of forced contact created between the chain and wheel 13 when the chain is under tension.
  • all of the main rollers 3 are driving rollers, but each roller is allowed to disengage itself from the driving action of the chain 14 as an effort is applied thereto by the fabric 2 which exceeds that required to overcome the frictional resistance between the pins 17 and bushings 15. This frictional resistance will be directly proportional to the amount of tension applied to the chain 14.
  • FIG 5 there is illustrated schematically a device 10 for tensioning the chain 14. Also in Figure 5 are shown, between the wheels 13, simple elements 19 for deflecting the chain 14.
  • each scouring system is provided at its end, in a manner known per se, with a squeezer unit 20, and at the bottom, with a deflecting roller 21 submerged in the collecting tank 6.
  • a conduit 22 for indirectly heating the bath by steam there are provided, moreover, a conduit 22 for indirectly heating the bath by steam, a conduit 23 for direct heating by steam, and a conduit 24 for supplying chemicals.
  • the centrifugal pump 9 is preferably a high pressure variable flow one.
  • the fabric 2 initially enters the collecting tank 6 at the bottom of the housing 1, then proceeds upwards under the drive of the main rollers 3 to undergo the triple scouring action described hereinabove. More precisely, as the fabric 2 is wound around each main roller 3, it undergoes a counterflow scouring action, then as it leaves the main roller 3, it is squeezed, and subsequently violently sprayed on the opposite side where it had been mainly subjected to a scouring action in counterflow. Successively, the fabric is passed over a fresh main roller 3 and the scouring actions are reiterated as far as the last of the main rollers 3. This arrangement results in the fabric coming out perfectly cleansed from the top of the housing 1 already after a relatively small number of turns or loops around the main rollers 3. In the embodiment shown, the fabric 2 is scoured five times in counterflow on one side and five times by spraying on the opposite side. Furthermore, the fabric is squeezed four times.
  • the invention achieves its objects.
  • a continuously operating scouring system for fabrics has been provided which, thanks to its output potential, adaptability, and the absence of any stretching of the fabric or otherwise during the scouring process, finds universal application to the treatment of any types of fabric, whether woven cloth, knitted fabric, in the flat or tubular condition thereof, in the course of their processing.
  • the scouring system of this invention is more efficient than conventional ones, thanks to the simultaneous application of three scouring actions or steps. This reflects in a reduced size of the system, which advantage is further enhanced by the prevailingly vertical arrangement of the system.
  • the materials and dimensions may be any ones to suit individual requirements.
