Definitions
- the present invention relates to an installation of textile yarn processing in tablecloth which includes a washing station for wet treatment, arranged upstream of a device, for pre-drying son, and a drying station located downstream of the pre-drying device.
- the subject of the invention is also a method implemented by this device.
- Textile threads generally undergo, before their use, especially for weaving, washing and / or bleaching treatments as well as dye. These different treatments are carried out by humid and result in excess humidity of around 100% at 300% by weight, and require a consecutive drying operation.
- a method of expressing the surplus is also known. humidity by an air overpressure. Such an expression allows gains comparable to those obtained by mechanical spinning. However, in the in the case of the treatment of yarns in plies, such a method of expression is not suitable, the wires not being supported during the air jet treatment and risking to be tangled under the effect of said jet.
- US-A-3,592,585 describes a processing machine sheet material involving pressure devices under form of blocks provided with blowing nozzles, these blocks being driven mechanically via a support cooperating with a shaft drive. Such a machine is specifically intended for a use in laundry and cannot be used in the field of finishing of textile threads.
- the object of the present invention is to overcome these drawbacks by proposing an installation and a process for pre-drying textile yarns after wet treatment to obtain optimal expression of a ply of yarns and easier and relatively inexpensive subsequent drying.
- the installation for treating textile yarns in the form of a web has a washing station for wet treatment, arranged in upstream of a wire pre-drying device, and a drying station arranged downstream of the pre-drying device, the wire pre-drying device being constituted by a carrier for supporting the layer of wires, with permeable transport surface, by mechanical wringing applied continuously on the web of threads running on the conveyor support, by a means of applying a pressure difference by air circulation through said sheet and through an enclosure for recovering the expressed humidity comprising at its upper part the carrier of support.
- the subject of the invention is also a method implemented by this installation characterized in that it consists essentially in applying simultaneously with a sheet of wet threads running on a conveyor on the one hand, a permeable transport surface, continuous mechanical action and, on the other hand, a pressure difference by air circulation at across said web.
- the accompanying drawing shows a device 1 for pre-drying textile threads after wet treatment placed in a wire treatment, downstream of a washing station 2 and upstream of a drying, not shown.
- this device penetrates a layer of wires wet 3, which requires a significant expression of the humidity it contains, before its final drying.
- the device 1 of pre-drying of textile threads after wet treatment is essentially constituted by a conveyor 4 for supporting the layer of wires 3, on the surface of permeable transport, by a mechanical wringing means 5 applying in continuous on the web 3 of threads running on the support conveyor 4, by means 6 for applying a pressure difference by circulation air through said sheet 3 and through an enclosure 7 for recovering the expressed humidity comprising at its upper part the carrier of support 4.
- This pre-drying device implements a process which essentially consists in applying simultaneously to the layer of wires wet 3 running on a conveyor 4 with transport surface permeable, on the one hand, a continuous mechanical spin action and, on the other part, a pressure difference by air circulation through said sheet 3.
- the air passing through the layer of wires wet 3 running can advantageously be previously heated.
- the carrier 4 for supporting the layer of wires 3 is preferably consisting of a mat permeable to air and water, driven in displacement by an independent motor not shown, in synchronism with conveyors upstream and downstream of the pre-drying device.
- the permeable mat forming the conveyor 4 can, for example, be constituted by a reinforced or perforated natural or synthetic rubber band over its entire surface or by a strip made of a mesh of wires textiles or metal or by a perforated metal strip.
- the mechanical wringing means 5 being applied continuously to the layer of yarn 3 is advantageously formed in the form of a mat permeable guided on 5 'guide cylinders and extending above the carrier 4 for supporting the layer of wires 3, the width of this mat being greater than that of the permeable mat forming said support conveyor 4.
- the guide cylinders 5 ′ of the mat forming the means spin mechanical 5 are mounted on a frame, not shown, fixed above of the enclosure 7 for recovering the expressed humidity.
- the fixing of this mounting frame for the guide cylinders 5 'of the mechanical means of spin 5 on the enclosure 7 of recovery of the expressed humidity is preferably made in an adjustable manner so that the spacing between the support conveyor 4 and the mechanical wringing means 5 is adjustable.
- the permeable mat forming said wringing means 5 is automatically driven in the direction of movement of the web of wires by being guided on the guide cylinders 5 '.
- the application continuous spin pressure on the threads ensures regular expression moisture over the entire length of said wires.
- This means drive can either be a mechanical means such that a chain or a toothed belt cooperating, on the one hand, with a pulley corresponding integral with one of the guide cylinders 5 'and, on the other hand, with a pulley secured to a motion reverser connected to a cylinder guide of the permeable mat forming the support conveyor 4 or directly to the drive motor of the latter, a motor own training.
- the means 6 for applying a pressure difference by air circulation through the web 3 of threads running on the conveyor support 4 is advantageously constituted by a suction device connected to enclosure 7 for recovering the expressed humidity.
- This means 6 includes, for example, an exhaust fan 8 connected to the enclosure 7 by means of suction pipes 9 and 10, with interposition of a settling means 11 provided with a pump 12 of draining of the recovered water.
- This means 11 is advantageously constituted as a cyclone.
- the enclosure 7 is advantageously provided with peripheral sealing means of the support 4, not shown.
- the suction applied in enclosure 7 by the means 6 applies fully to the level of the support conveyor 4 and causes air circulation through said transport 4, the ply of wires 3 scrolling on the latter and the wringing means 5 moving in continuous together with the wire layer 3.
- the humidity contained in the layer of wires 3 is thus expressed, on the one hand, mechanically by the pressure action of the wringing means 5 on the support conveyor 4 and, on the other hand, by the suction effect of said humidity by the air passing through said layer of wires 3.
- the drops of water possibly remaining by capillarity, during mechanical expression, on the wires forming the sheet are entrained by the air current created artificially in the layer of wires. It follows that the expression of humidity is significantly improved.
- the means 6 for applying a difference of pressure by air circulation through the web 3 of threads running on the support conveyor 4 can also be constituted by a device application of air pressure above the ply of wires 3, through the wringing means 5, between the guide cylinders 5 'of the latter, the mounting frame of the wringing means 5 on the enclosure 7 then being provided with a tight closing cowl cooperating at its periphery lower with said enclosure 7.
- the space delimited by the cowling surrounding the wringing means 5 is connected to a supply means of pressurized air and air, passing through the permeable mat constituting said medium 5, as well as the ply of wires 3 and the support conveyor 4 also permeable, is evacuated into the enclosure 7 causing moisture adherent by capillary action, the enclosure 7 then being provided with a device not shown pumping the expressed humidity. It is also possible, at like the preferred embodiment described in connection with the figure annexed to carry out a settling treatment of the air charged with humidity of enclosure 7 by means of a cyclone or the like.

- Such an embodiment makes it possible to optimize the application of pressure difference in addition to the mechanical expression carried out by through the wringing means 5, by the fact that the pump air circulation used acts simultaneously on the layer of wires 3 to pre-dry, both by pressure and by suction with air continuously recycled.
- the means 6 for applying a pressure difference by air circulation to through the web 3 of threads running on the support conveyor 4 can be supplemented by an air heating device applied to said sheet of wires, not shown in the accompanying drawing, in the form of a battery of electric or steam heater, gas heater or other.
- the air passing through the sheet wet threads 3 running can advantageously be previously heated.
- the wringing means 5 In order to improve the mechanical expression of humidity, it can, moreover, be provided to equip the wringing means 5 with cylinders pressure (not shown) mounted in the mounting frame on the enclosure 7, between the guide cylinders 5 ′, vertically displaceable by compared to the permeable mat constituting the wringing means 5 against the action return springs.
- cylinders pressure (not shown) mounted in the mounting frame on the enclosure 7, between the guide cylinders 5 ′, vertically displaceable by compared to the permeable mat constituting the wringing means 5 against the action return springs.
- the pre-drying device according to the present invention is advantageously mounted downstream of a washing station 2, shown schematically in the accompanying drawing, and in which the washing is, of preferably made with heated water.
- a washing station 2 shown schematically in the accompanying drawing, and in which the washing is, of preferably made with heated water.
- Such washing makes it possible to obtain the outlet of the washing station 2 a sheet of wire which is wet at temperature relatively high, so that the pre-drying operation in the device 1 according to the invention is facilitated, the hot washing water can be expressed more easily from said sheet of yarn, because it adheres less to their fiber.
- the invention it is possible to carry out an expression high humidity of yarn having undergone a washing operation alone or after dyeing or other treatment with significant gains in expression, at knowledge of the order of 50% compared to the process implemented by the usually pre-drying devices. As a result, the consecutive drying operations can be considerably reduced, so the corresponding costs are also reduced to a large extent measured.
- the invention can also be used in wet treatment of threads, namely, especially for waterproofing, anti-UV treatment, fireproofing, the dye, etc., the washing water then being replaced by a treatment or by a dyeing bath for impregnating the layer of threads.
