Definitions

  • the invention relates to a method according to the preamble of claim 1. Such a method belongs to the prior art according to Article 54 (2) EPC.
  • Permanent decating effects can usually only be achieved under discontinuous working conditions, e.g. B. with the help of a boiler decatizing machine.
  • the goods and idler fabric are wound together on a decatizing and treatment cylinder and then treated in an autoclave under high temperature conditions.
  • GB-A-2 194 804 discloses a process for the continuous permanent decatation and fixing of web-like textile goods, such as woven fabrics, knitted fabrics or the like, in which the moistened textile goods are guided over a rotatably mounted, heated cylinder with a closed surface and by one Deflection rollers looped, impermeable pressure tape is pressed against a part of the cylinder surface and in which the surface temperature of the heated cylinder is greater than 140 ° C.
  • DE-PS 35 39 792 shows a method of how permanent decatation effects can also be achieved in a continuous manner. Essentially it is a matter of the fact that chemical fixing agents have to be switched on parallel to the physical effect of the decaturing so that a permanent degree of fixing is ensured. According to this known method, the chemical fixatives are applied with the addition of hygroscopic substances in the area of a foulard - that is, before the tensioning and drying process.
  • the fixing agent is activated by controlled rewetting.
  • the fixing agent activated by the moistening is reacted in the fiber structure of the goods in the area of the decatizing and fixing device under temperature and mechanical pressure.
  • the object of the invention is to achieve a permanent decatizing and fixing effect without the use of chemicals of any kind, the loss of goods being indistinguishable on both sides, that is to say on the left and right side of the goods.
  • the textile material is moistened in a moisture range between 20 and 35%
  • the textile material is also moistened in the second treatment stage.
  • the moisture of the textile goods and the surface temperature of the heatable cylinder can expediently be changed independently of one another in the two treatment stages.
  • the treatment in a third processing stage can be regarded as a finish decatur as required, whereby only gloss, volume and grip can be improved or corrected.
  • a finish treatment is carried out on the same decatizing machine; however, the textile material is only allowed to come into direct contact with the surface of the heated cylinder.
  • Treatment with the two treatment stages I and II is sufficient for certain textile goods qualities. In this case, however, it is expedient to introduce the textile material leaving treatment stage II into a suction station.
  • the pressure band acting on the textile material is impermeable to the media, as a result of which the amount of moisture introduced via the textile material is converted into steam by means of the heating of the cylinder and the pressure band.
  • the temperature of the textile material can also be chosen to be so high that permanent fixing effects can occur under high temperature conditions. This effect is based on the knowledge that even when using high contact temperatures, e.g. B. up to 160 - 180 ° C, no damage or yellowing occur in the textile goods, provided that sufficient moisture of the textile goods is ensured.
  • controllable moisture values of the textile material are used compared to the prior art. This important factor has so far been neglected in all known decating methods. It was generally always believed that moisture got into the goods through steam. The opposite is true. Rather, the steam dries out the goods. Measurements show a loss of moisture in the goods of approx. 2 - 3% during a normal decatation process.
  • the decatizing and fixing method according to the invention is based on the fact that the moist state of the textile material to be treated can be individually corrected and influenced by an effective moistening device before each treatment stage. It has proven particularly effective if the humidification device is formed from a combination of open damping (steam lock) and direct contact with the finest water mist.
  • the textile material and the enclosed air are first heated in the same, so that in the subsequent spraying, considerably more water can be offered before the dew point limit is reached.
  • treatment stage I is already on the left side of the textile. With this wet fixation, the steam conversion in the area between the heatable roller and the pressure belt of treatment stage I reduces the fabric moisture from 85 to approx. 40 - 48%. In the subsequent treatment of the right side of the goods in treatment stage II, the moisture is already reduced to approximately 17-20%, so that in principle the desired residual moisture is already achieved after treatment stage II.
  • a final finish-decatizing treatment that goes beyond this can only improve the fixing effect achieved in terms of gloss, volume, grip and design.
  • I and II ( Figures 1 and 4) denote the two treatment stages.
  • 1, 2, heated cylinders with a closed, smooth surface are indicated, which are heated in a suitable manner so that their surface temperature is greater than 140 ° C.
  • 3 denotes a median-impermeable pressure band, which is guided around part of the associated heatable cylinder 1, 2 and over deflection rollers.
  • 4 is a tension roller, while the deflecting roller 5 can be heated independently of the cylinder 1 or 2.
  • the heated deflection roller 5 has the task of heating the printing belt 3.
  • the textile material 6 is guided over the part of the cylinder 1 or 2 wrapped around by the printing tape 3 so that it comes to lie between the latter and the printing tape 3. Before the textile material 6 is introduced into the gap between the printing belt 3 on the one hand and the heatable cylinder 1 or 2 on the other hand, the textile material 6 is passed through a moistening device 7 or 8.
  • a humidification device 7 is provided in each treatment stage I and II. Details of an expedient embodiment of the moistening device 7 are shown in FIG. 2 of the drawing. There, this device consists of a steam lock 7a with a directly downstream rotor spray device 7b, the intensity of the humidification being able to be carried out by regulating the pressure and the amount of water. Regulation can also take place automatically via corresponding setpoint specifications, regardless of the type of textile material, but depending on the speed of the textile material.
  • the Mollier-i-x diagram (FIG. 3) makes it easy to see the advantages between the damping and the water spray immediately following it.
  • the textile material leaving treatment zone I is introduced into subsequent treatment stage II, which in the embodiment according to FIG. 1 contains the same devices as treatment stage I.
  • the heatable cylinder 2 is a mirror image is arranged to the heatable cylinder 1, the mirror plane being indicated by AA. This ensures that the textile material 6 rests on the heatable cylinder 1 or 2 in treatment stage I with its left side and in treatment stage II with its right side. This ensures an even loss of goods.
  • the textile material 6 leaving treatment stage II is optionally fed to a suction station, which is indicated in FIG. 1 by reference number 9.
  • FIG. 4 differs from that according to FIG. 1 in that a humidification device 8 is provided only in treatment stage I, in which the textile material 6 is subjected to 100% humidification.
  • This moistening device 8 consists of a hot water trough, the driven roller 10 taking over the transport of the textile material 6.
  • a dancer device 13 connected downstream of the driven feed roller 12 ensures low-tension running of the goods 6 into the decatizing machine of treatment stage I.
  • This drive measure ensures that the dangerous expansion moments in the goods 6 caused by hot water treatment are avoided during the passage.
  • the heat transfer value is so high due to the supply of heat on both sides that the textile material 6 already has a moisture content of approx. 85% to 40-48% after the treatment stage I. has broken down.
  • the evaporation occurs as soon as the textile material 6 leaves the cylinder 1.
  • a sensitive dancer device 14 scans the goods 6 without load and ensures automatic readjustment of the goods transport, which is carried out by a carrying belt 15. From here, there is now a low-tension transport of goods to treatment stage II, where the right side of the goods is subjected to the fixing treatment.
