Definitions

  • a method of continuous decatizing includes the steps of passing a fabric to be decatized around a steaming g6 cylinder and around a suction cylinder.
  • a backing Field D 5 E 8 cloth which applies pressure to the fabric can be tensioned by different amounts at each cylinder.
  • a steaming apparatus in which a fabric web together with a backing cloth passes over a plurality of steaming rollers and deflecting rollers arranged inside a vacuum chamber.
  • a disadvantage of this prior proposal is the relatively small area of the fabric web on which the steam acts.
  • a further disadvantage of this previously proposed apparatus is that as a result of the numerous deflection points for the fabric and the backing cloth a relatively low surface pressure is exerted during the steaming period and the cooling period, on the fabric that is to be decatized.
  • a continuously operating decatizing machine with a felt backing cloth travelling round a cylinder has also been proposed.
  • part of the cylinder is used for steaming and another part for applying suction to the fabric.
  • the surface pressure caused by the tensile force in the backing cloth is the same in both the steaming period and in the suction period.
  • a method of continuously decatizing a fabric web comprising the steps of applying steam at a steam-applying station to the fabric web as the web traverses a cylindrical path and is subjected to pressure generated by tension applied to length of backing cloth, and applying suction at a suction-applying station to the fabric web as the web traverses a cylindrical path and is subjected to pressure generated by tension applied to the length of backing cloth, the pressures in lengths of the backing cloth at the steam applying station and at the suction applying station being variable independently of one another.
  • FIG. 1 is a vertical section through a first embodiment of decatizing apparatus for carrying out the method in accordance with the invention
  • FIG. 2 is a vertical section through a second embodiment
  • FIG. 3 is a section similar to that of FIG. 2 but also showing controllable transmission arrangements
  • FIG. 4 is a vertical section through a third embodiment
  • FIG. 5 is a vertical section through a fourth embodiment.
  • An endless backing cloth 1 (FIG. 1) which consists of a satin fabric or an endless belt of synthetic material or the like and serves primarily to transport the fabric 2 which is to be treated, passes over cylinders 3 and 4 under comparatively low initial tensile stress.
  • Each of the cylinders 3 and 4 has on its periphery a wrapping winding of the same material as the backing cloth 1, or a shrunk-on seamless tube. 5 and 6 respectively, of felt or the like. This ensures that the fabric 2 passes between the backing cloth 1 and the tube 5 or 6 and is subjected to each phase of the treatment without elongation.
  • the steam treatment on the cylinder 3 takes place from the inside to the outside or from the outside to the inside.
  • the fabric is subjected to suction and is cooled.
  • the backing cloth 1 is guided over deflecting rollers and is held under initial tension by means of a tensioning hydraulic or pneumatic cylinder ll acting on a deflecting roller 110. This applies a basic tension to the whole system and thus applies a minimum surface pressure to the fabric 2 which is to be decatized.
  • the backing cloth 1 is driven by the feed roller 7.
  • the tensile stresses in the parts of the backing cloth 1 passing round the cylinders 3 and 4 respectively can be adjusted independently of one another.
  • the withdrawal roller 8 has a higher speed of rotation than the feed roller 7.
  • the effective speed of rotation of the withdrawal roller 8 is thus only a few per cent higher than the speed of the feed roller 7, so that the speed difference is available as work of deformation of the backing cloth 1 passing around the cylinder.
  • the high speed of rotation of the withdrawal roller 8 leads to elongation of the circulating backing cloth 1 along the section between the feed roller 7 and the withdrawal roller 8 and therefore to a directly proportional increase in the tension of the backing cloth 1 in the longitudinal direction.
  • a radial force or pressure also results from the longitudinal tension of the backing cloth 1, and therefore the surface pressure on the fabric 2 in the region of the cylinder 3 is also increased when the speed of rotation of the withdrawal roller 8 is higher.
  • the controlled speed of rotation of the withdrawal roller 8 is then directly proportionally transmitted to the feed roller 9.
  • the feed roller 9 thus takes over the same function for the cylinder 4 as the feed roller 7 for the cylinder 3.
  • the withdrawal roller 10 following the cylinder 4 provides for a particular surface pressure which can be selected independently of the cylinder 3.
  • the tension in the backing cloth 1 can be adjusted within wide limits by way of the tensioning cylinder 11 and the deflecting roller 11a, and therefore the surface pressure exerted on the cylinder 4 can be made substantially higher than the surface pressure on the cylinder 3. This is possible only if the surface pressure resulting from the tension of the backing cloth, produced by way of the tensioning cylinder 11, acts on the cylinder 3 and the withdrawal roller 8 has a higher speed than the feed roller 7. The steaming process takes place with minimum surface pressure under these circumstances, that is to say with the low tensile force in the backing cloth 1.
  • the feed roller 9 receives the backing cloth 1 and the fabric 2 from the cylinder 3 at the same speed and conveys them to the cylinder 4.
  • the maximum value of the surface pressure on the periphery of the cylinder 4 is obtained when the speed of the withdrawal roller 10 as compared with that of the feed roller 9 is a maximum.
  • each cylinder is preceded by a respective one of feed rollers 7, 9 and I3 followed by a respective one of withdrawal rollers 8, l0 and 14.
  • a process particularly suitable for decatizing polyester fabrics is steam treatment on the cylinder 3 with superheated steam or alternatively with saturated steam, followed by suction on both of the cylinders 4 and 12 under higher surface pressure than in the case of the steam treatment.
  • this treatment permits the greatest possible stabilization.
  • the subsequent steam treatment with saturated steam at a relatively low surface pressure produces the required fee! and the desired volume of the fabric.
  • the final treatment with steam should be followed by intensive cooling process in each case.
  • FIG. 3 of the drawings is a purely diagrammatic illustration of the drive system of the decatizing of FIG. 2.
  • an electromechanical drive is considered.
  • this drive can be replaced by hydraulic or electronic and electrical drive or the like.
  • a transmission receives the necessary torque by way of a driving motor 16 and can be regulated within wide limits, whereby the working speed for the whole decatizing machine is finally determined.
  • the drive is first transmitted at a suitably reduced speed to the feed roller 7 and the circulating backing cloth 1 is thereby set in motion.
  • the controlled speed of rotation of the transmission 15 is transmitted by way of a shaft 17 to a following transmission 18. This makes it possible to transmit a higher speed of rotation to the withdrawal roller 8 by suitable regulation of the transmission 18. This establishes an increase in the tension of the backing cloth 1 in the region of the cylinder 3 between the rollers 7 and 8, and this causes the surface pressure to rise.
  • the controlled speed of rotation of the withdrawal roller 8 is now transmitted directly and positively to the feed roller 9. Also, the controlled speed of rotation of the transmission 18 is transmitted by way of a shaft 19 to a further following transmission 20.
  • the drive speeds for the withdrawal rollers 10 and 14 can be regulated by way of transmissions 20 and 21 in the manner described above.
  • the driven shaft 22 of the transmission 20 represents the input for the transmission 21.
  • a change in the surface pressure on the cylinders 3 and 4 is effected by an arrangement in which in addition to the different speed regulation for the withdrawal rollers 8 and 10 a different surface pressure in each case is exerted on the circulating backing cloths l and 1a by way of tensioning rollers 23 and 24.
  • the whole system is thus moved not by a single backing cloth 1 but by two backing cloths 1 and la which are unequally tensioned.
  • the change in the surface pressure for the cylinders 3 and 4 is effected by an arrangement in which an additional surface pressure is exerted on the backing cloth 1 with the aid of a respective one of two circulating pressure webs 25 and 26.
  • These pressure webs 2S and 26 are guided over deflecting rollers of which at least one in each case, for instance the deflecting roller 27 and 28 respectively, can be displaced and held in position. in this way the contact pressure force of the corresponding pressure web 25 or 26 can be changed.
  • a separate speed regulation of the withdrawal rollers 8 and 10 can be omitted in this case.
  • the pressure webs 25 and 26 are pre-stressed with different forces by way of the deflecting rollers 27 and 28, and 29 and 30 if necessary, acting as tensioning rollers.
  • the deflecting rollers 27 and 30 are capable of being displaced and held in position.
  • Endless webs consisting of textile fabric may be used as the pressure webs 2S and 26.
  • metal webs with perforations are used for transmitting large tensile forces. These metal webs must be resistant to corrosion and their structure must be made such that the media necessary for the treatment, for instance steam, air and the like, can pass through without hindrance.
  • the total surface pressure is then produced by the sum of the separate forces producing surface pressure, that is to say the tensile force of the backing cloth, the higher speeds of rotation of the two withdrawal rollers 8 and 10 and the tensile forces of the pressure webs 25 and 26.
  • a method of continuously decatizing a fabric web comprising the steps of applying steam at a steam-applying station to the fabric web as the web traverses a cylindrical path and is subjected to pressure generated by tension applied to a length of backing cloth, and applying suction at a suction-applying station to the fabric web as the web traverses a cylindrical path and is subjected to pressure generated by tension applied to a length of backing cloth, the pressures in the lengths of the backing cloth at the steam-applying station and at the suction 8 applying station being variable independently of one another.
  • a method according to claim 1, comprising the further step of applying steam at a further steamapplying station as the web and a length of backing cloth traverse a cylindrical path, the first application of steam employing saturated steam with the web under relatively low pressure and the second application of steam employing superheated steam with the web under relatively high pressure.
  • a method according to claim 1 comprising the further step of applying suction at a further suctionapplying station as the web and a length of backing cloth traverse a cylindrical path, the steam application employing at least saturated steam and both of the suction steps taking place with the web under higher surface pressure than in the steam applying step.
