Description
- This invention relates to a washing system for washing a long strip of fabric such as a slide fastener chain, slide fastener tape, surface fastener and ribbon.
- As is well-known, surplus dye remains adhered on fabric after it is dyed. Such surplus dye should be washed off from the fabric. With a conventional washing system, a long fabric strip is brought into a washing tub filled with washing liquid, steeped in the tub, guided up and down in a meandering manner, washed therein, and then drawn out from the washing tub. Sometimes a plurality of washing tubs are arranged in rows to wash the fabric strip therein.
- With this conventional washing system, the dyed fabric strip should be very slowly guided through the washing tubs. This washing system is disadvantageous in that washing efficiency cannot be improved and a great amount of washing liquid has to be provided for satisfactory washing. At present, there is a great demand for production of a good assortment of fabric strips in small amounts. In some cases, a slide fastener tape is dyed in one color for up to, say, some ten meters and is then dyed in a different color, and so forth. To wash such slide fastener tape by the conventional washing system, it is necessary to stop the washing system according to the dye colors and to use new clean washing liquid. Therefore the conventional washing system is not suitable to washing such fabric strip which is sectionally dyed in different colors.
- EP-A-0 180 755 discloses a system in which a nozzle feeds liquid vertically down through the fabric, and liquid passes into a drain funnel. The nozzle is located at the top on an inverted U-shaped path of the fabric, which is depressed downwards as it passes under the nozzle.
- It is therefore an object of this invention to provide a washing system which can overcome the inconveniences of the conventional washing system and wash the long fabric strip efficiently without using a great amount of the washing liquid, coping with the demand for production of a variety of long fabric strips in a small amount.
- According to this invention, there is provided a continuous washing system for a long moving fabric strip, comprising:
- (a) a plurality of injection nozzles located at one side of a conveying path for the fabric and spaced from one another for injecting washing liquid into the fabric strip; and
- (b) a plurality of drainpipes located opposite the injection nozzles at the other side of the conveying path and having hollow portions for absorbing the washing liquid injected by said injection nozzles,
- With this arrangement, the washing liquid is injected by the injection nozzles toward the dyed fabric strip guided along the conveying path. The stained washing liquid is sucked into the drainpipes so that the washed fabric strip will not be stained. Even when it is dyed in different colors, the fabric strip can be always washed by clean washing liquid without interrupting the washing process.
- Compared to the prior art, the arrangement of the present invention requires less space for the washing system and the washing system has twice the cleaning efficiency of the prior art washing systems relative to the number of drainpipes.
- FIG. 1 is a cross-sectional view of a washing system for a long fabric strip according to this invention; and
- FIG. 2 is an enlarged perspective view of a main part of the washing system.
- As shown in FIG. 1, a washing system comprises components located in and outside a hollow housing 1. A
guide roller 2 is located at an upper portion in the housing 1, and aguide roller 3 is located above the housing 1. Drawing-in and drawing-outrollers guide rollers rollers 5, 6 form a path 8 (indicated by arrows in FIG. 1), which downwardly leads a dyed fabric strip W into the housing 1 via an inlet 6 at the upper portion of the housing 1, then upwardly via theroller 4 toward an outlet 7 at the top of the housing 1. Thepath 8 is in the shape of U in the housing 1. - A plurality of
drainpipes 9 are arranged with preset intervals in parallel to theroller 4 in the U-shaped space of thepath 8. A pair each of injection nozzles are associated with eachdrainpipe 9 to inject washing liquid (i.e. hot water) to the outer surface of thedrainpipe 9 via the dyed fabric strip W guided along thepath 8. As shown in FIG. 2, theinjection nozzles 10 inject the washing liquid flatly and divergently onto the fabric strip W. Thedrainpipes 9 have intakes 11 to receive the washing liquid therein. - The
drainpipes 9 are communicated by apipe 12. The washing liquid received in thedrainpipes 12 is drained by a pump and an absorption canister (which are not shown in FIG. 1). As shown in FIG. 2, each drainpipe 9'has a pair offlanges 13 13 at its opposite ends so that the dyed fabric strip W is guided in contact with the outer surface of thedrainpipe 9 between theseflanges drainpipes 9 to be washed together. Each of the right and left injection nozzles is connected to each branch of thefeed pipe 14. Anexhaust port 15 is located at the bottom of the housing 1. - A
dehydrator 16 is positioned above the housing 1 to dehydrate the washed fabric strip W. Thedehydrator 16 of FIG. 1 comprises a plurality ofair nozzles 17 which are arranged vertically with preset spaces.Exhaust pipes 18 are installed in front of theseair nozzles 17 to be in contact with the fabric strip W, havingintake ports 19. - In the foregoing embodiment, one
drainpipe 9 is associated with each pair ofinjection nozzles 10. On the contrary, onedrainpipe 9 which is long and has flat portions may be used to serve a plurality of theinjection nozzles 10.Such drainpipe 9 has intake ports associated withrespective injection nozzles 10. - The U-shaped
path 8 is advantageous to make the washing system compact and to dispose a pair of theinjection nozzles 10 for eachdrainpipe 9, thereby simplifying the washing system. Otherwise, thepath 8 may be straight. - An example of a
dyeing unit 20 is shown in the left upper part of FIG. 1. Thedyeing unit 20 spray-dyes to both surfaces of the fabric strip W, guiding it through asteamy atmosphere 22 to fix the dye color. Then the spray-dyed fabric strip W is guided into the washing system. In such arrangement, the fabric strip W can be dyed in different colors to desired lengths, which is advantageous to produce a good assortment of dyed fabric strips W in a small amount. - The dyed fabric strip W is conveyed along the
path 8 to be washed by the washing liquid supplied by theinjection nozzles 10. The stained washing liquid is completely drained into thedrainpipes 9 by the suction pump. The washed fabric strip W is then dried by hot air applied via theair nozzles 17 of thedehydrator 16. Thus, the fabric strip W is always washed by clean washing liquid, being not affected by the stained washing liquid. - The dyed fabric strip W is conveyed with its one side in contact with the outer surface of the
drainpipes 9. The other side of the fabric strip W confronts with theinjection nozzles 10 with a preset space therebetween. Even a surface fastener can be reliably washed without damaging hook elements embedded thereon. - By means of this invention, a long fabric strip is conveyed along the path to be washed by the washing liquid sprayed by injection nozzles, which are located along the conveying path with the preset spaces. The drainpipes are associated with respective injection nozzles to receive the used washing liquid. The fabric strip is successively washed by clean washing liquid. Therefore, even if it has differently colored portions, the fabric strip can be continuously washed by clean washing liquid, thereby improving the washing efficiency. It is also possible to reduce the amount of the washing liquid.
