    • D04H11/00—Non-woven pile fabrics

Definitions

  • the invention relates to the manufacture of pile fabrics wherein the pile forming substance, e. g. yarn, threads, filaments, or sliver, are assembled in spaced parallel layers and consolidated with a solidifying medium to form a solid block which is cut transversely of the run-of the pile layers to form slabs which are backed with a plastic or other layer so that the tips of the pile are fixed in the backing, the consolidated or solidified medium being ultimately removed from the pile.
  • the pile forming substance e. g. yarn, threads, filaments, or sliver
  • the object of the invention is to enable a method of the characterabove referred to, .to be carried out more expeditiously and economically, and to facilitate the determining-ofthe-density of the pile fabric produced.
  • a long mould which is preferably adapted to permit of the long block so formed being out directly into slabs, or alternatively into sections' for convenient handling and ultimate cutting into slabs.
  • This medium which is preferably a solution of soluble alginate, such as ammonium alginate, containing 'an insoluble salt, such as di-calcium phosphate-which can form a gel for example by the addition of Fon'nalin.
  • This medium increases in viscosity asthe setting .point is approached, and this is an item to be considered. in a method of manufacturing a pile fabric accordingto. the invention where the pouring or layering of the solidifying medium is extended.
  • the two reactants are stored in'bulk' separately and are delivered under control to a mixing :vessel, the discharge of which to the mould is controlled, so that the relative quantities of the two reactants as well as the time during which they are being'rnixedand-discharged can be determined.
  • Th'efiprogressive assembling of layers 'of solidifying medium and pile formingsubs'tance is preferably elfected softhatthe latter is under tension and is pressed into the solidifying medium as this thickens prior to setting.
  • the pile forming substance when sliver is used as the pile forming substance it may be sized and dried to give it stability. However, under wet conditions as when layered in contact with a layer of solidifying medium, the dried soluble size would be liable to dissolve and sink in the medium before the latter has set sufliciently to support .the sliver.
  • the sliver is in the first instance spray sized with a water soluble size and dried to give a paper-like handle, upon which is superimposed a suitable pattern of a water insoluble size similar in nature to the solidifying vmedium.
  • this setting solution When applied, this setting solution dissolves the soluble size in proximity to it, and thus embeds itself into the sliver tissue; it then thickens and sets giving a supporting framework to the sliver which is water-insoluble, as when in contact with the consolidating or solidifying medium in the mould.
  • This supporting pattern or framework is so disposed as to allow the free flow of consolidating medium through the layers of sliver without disturbing .the orientation of the layers of sliver and their component fibres. It is an. advantage, when sizing sliver, that no physical contact .is .made between the web of fibres and the size applying apparatus, such a method prevents the possi-. bility of licldng.or-dist-urbance of the web of'fibres.
  • a mixing apparatus as hereinbeforedescribed, would be suitable for. continuously preparing such a solidifying insoluble size immediately prior to its application to the web.
  • the invention also comprises apparatus for carrying out the method of manufacturing a pile fabric such as above referred to.
  • Figure 1 is a side-sectionalelevation and Figure 2 is an endelevat-ion illustrating one example of apparatus for preparing the consolidating or solidifying medium and progressively layering it and pile forming substancein a long mould;
  • Figure 3 is a plan of the layering-device
  • Figures 4 and 5 arerespectively, a side elevation and a plan of a sectional mould
  • Figure 6 schematically illustrates a long moulded bloc before being cut into sections
  • Figure 7 illustrates one section of this block ready for cutting into slabs
  • FIGS 8, 9, 10 and 11 illustrate successive stages in the known subsequent treatment of slabs
  • Figure 12 is a side elevation illustrating an alternative form of the apparatus for storing and mixing the solidifying medium.
  • Figures 13 and 14 are sectional elevations of alternative forms of mixing vessel.
  • two storage tanks 1 and 2 respectively, contain the bulk solutions whichvare to be mixed in a mixing vessel 3 to form the consolidating or solidifying medium.
  • the tank 1 contains'for example alginate solution with suspension of insoluble salt, and the other contains the setting medium, for example, Formalin solution.
  • the tanks 1 and 2 have-flexible delivery pipes 4 and 5 fitted with valves.6 and 7 respectively for cut off and controlling therate of discharge to the mixing vessel 3.
  • the mixing vessel 3 has a discharge nozzle 8 which may be fitted with a valve 9 for controlling the rate of discharge for layering the solidifying medium in the mould 10.
  • the nozzle 8 is fan-shaped or splayed as shown in Figure 3 to spread the solidifying medium evenly.
  • the tanks 1 and 2 and the mixing vessel 3 are'carried by a carriage 11 provided with wheels 12 running on a gantry 13, above the mould 10.
  • the mould 10 can be of any desired length.
  • the layering device 14 is fitted with a bar 15 over which the pile forming substance 16 is led from the spool 17.
  • the bar 15 is arranged just about level with or slightly below the side plates of the layering device 14 and thus acts as a doctor.
  • the layering device 14 is supported from the carriage 11 by screw-threaded rods 18, actuated by a suitable lifting device for simplicity indicated by nuts 19 so that the depth of the layering device 14 can be accurately adjusted.
  • the layering device 14 is raised by the screws 18 a predetermined amount equal to the desired spacing of successive layers of yarn, and the carriage 11'is returned in the direction of the arrow 23.
  • the raising of the screws by rotation of the nuts 19 may be effected auto matically by a trip device.
  • a fresh spool 17 wound with yarn is inserted in the layering device, the ends of the yarn being secured to a rod 20 placed on the previously formed combined layer of solidifying medium and yarn.
  • the valves 6 and 7 are re-opened and the carirage 11 is again moved in the direction of the arrow 21 and a second layer of medium is layered on the first layer and a layer of yarn on the second layer.
  • the carriage 11 is reciprocated back and forth until the required number of layers has been built up progressively.
  • the yarn or other pile forming substance 16 is pressed into each viscous layer of solidifying medium.. It is essential in order to obtain a final homogeneous mass that each successive layer of consolidating medium i laid when the'preceding layer has increased in viscosity sufiicient to support the next layer of yarn, but has not fully set.. Each penultimate layer of this medium is very viscous prior to setting. When sufficient layers have been deposited to form a block extending throughout the mould and the block i sufficiently set or solid, it is cut transversely of the run of the yarn layers directly into slabs or alternatively into blocks of convenient size to facilitate removal and subsequent cutting into slabs,
  • a suitable conveyor 24 may form the bottom of the mould so enabling the block to be moved forward in predetermined increments according to the thickness of the slabs required towards a vertical cutting device fixed at one end 41 of the mould.
  • the mould 10 may be in detachable sections 25 as indicated in Figures 4 and 5.
  • the spools 17, Figure 1 can be wound with coloured yarns or sliver strands in a similar manner to that adopted with the spools of an Axminster type loom, each spool being prepared with selected colours representing one pick in the repeat of the pattern to be produced.
  • the carriage 11 may be propelled manually or by power. 7
  • valves 6, 7 and 8 gear pumps or other pumps 34, 35 and 36 may be used as indicated in Fig ure 12.
  • the mixing in the mixing vessel 3 can be effected by any usual mixing means, for instance by arranging nozzles 37 and 38, Figure 13, from the valves 6 and 7 to co-operate to form turbulence, with or without the assistance of baffles 39; or rotary mixing propellers 40, Figure 14, may be used.
  • a method of manufacturing a pile fabric as specified in claim 5 comprising mixing controlled quantities of solidifying medium forming reagents and immediately delivering the resultant mixture to the mould.
  • a method of manufacturing a pile fabric as specified in claim 5 comprising mixing controlled quantities of solidifying medium forming reactants, immediately delivering the resultant mixture to the mould, and laying the successive layer of pile forming substance after each layer of solidifiable medium increases in viscosity without fully setting.
  • a method of manufacturing a pile fabric as specified in claim 5 comprising the steps of subdividing said block into shorter blocks and cutting said shorter blocks into slabs.
  • Apparatus for moulding a block of layered solidifiable medium and pile forming substance comprising a mould, a layering device within said mould comprising a transverse doctor bar, means for supporting a spool of pile forming substance to be passed around said bar, means for delivering solidifiable medium in front of said bar, rails above said mould, a carriage movable on said rails longitudinally of said mould, and means on said carriage and adjustably traversing said bar along said mould at the required height in said mould.
  • Apparatus for moulding a block of layered solidifiable medium and pile forming substance comprising a mould, a layering device within said mould and comprising a transverse doctor bar, means for supporting a spool of pile forming substance to be passed around said bar, a mixing vessel for solidifiable medium, said vessel being fitted with a controlling valve and a nozzle for delivering solidifiable medium in front of said bar, rails above said mould, a reciprocatory carriage on said rails, said carriage supporting separate tanks for storing the reactants of solidifiable mixture for supplying said mixing vessel, and means on said carriage and adjustably supporting said layering device at successively varied heights in said mould.
