Definitions

  • the invention relates to a method according to the first part of claim 1 and extends to a clamping frame for performing the method.
  • the temperatures prevailing over the treatment section are measured continuously in order to correct the amount of energy expended depending on the deviations from the target temperatures required for the optimal treatment and, if necessary, to adapt the treatment rate to an average of the temperature deviations, so that For example, the speed at which a material web is guided through a tenter frame is slowed to the extent and for the duration that the temperature falls below or falls below the target temperatures.
  • temperature sensors In order to determine the temperature profile over the length of a treatment section as precisely as possible, temperature sensors must be provided in a correspondingly dense sequence along the treatment section. Contactless temperature sensors such as radiation pyrometers are very expensive. Their use to determine the temperature profile over the treatment line allows an optimization of the web speed and thus an energy saving, but the investment required to do so largely removes the operating cost advantage. Inexpensive non-contact temperature measuring devices are also known (see “Textil cleanse” April 1981, p. 55), but they have to be arranged within a boundary layer that is only a few millimeters thick, so that touching the measuring devices with the web cannot be excluded and markings on the web can arise.
  • the amount of heat given off by the heated treatment medium to the material web which is proportional to the difference between the temperature of the incoming treatment medium and the temperature of the goods, is a function of the difference between the temperature of the arriving treatment medium and the temperature of the reflected or flowed through treatment medium certainly.
  • this measuring method delivers a temperature profile corresponding to the web temperature.
  • the invention has for its object to optimize the duration of treatment in the heat treatment of a textile web, and also to determine the temperature profile of the textile material over the treatment line, as in the method known from DE-A-31 48 576, but without this
  • the respective temperature of the textile goods must be measured directly or the temperatures of the treatment medium flowing in and out must be measured.
  • the material web speed is regulated.
  • the procedure can be such that values of the amounts of energy expended per unit of time are fed to a computer which compares the location of the treatment path with the maximum value deviation and corrects the target path of the treatment path and corrects the material web speed accordingly by a predetermined dryness - and to adhere to the fixing time.
  • the method according to the invention takes advantage of the knowledge that the amounts of heat supplied are, for example, proportional to the degree of opening of valves of the treatment medium flows.
  • the valve positions can be tapped electrically in a manner known per se and displayed, for example, by means of light-emitting diodes.
  • the stenter In order to make the transition point between the dry treatment and the fixing treatment clear, the stenter is first heated. After the temperature has been reached, a certain heat consumption occurs with the valve positions also determined. The resulting measurement values can be trimmed to zero. In this way, the idle power of the stenter, that is, the portion that results from machine-related losses, can be eliminated. After the web has been retracted into the stenter, new measurement values are obtained which only correspond to the proportion for heating up the web and evaporating the water. In this way, the transition point on the treatment line between the dry treatment and the fixing treatment can be displayed.
  • a stenter frame consisting of several drying and fixing fields, each with a fan circulating a stream of a gaseous treatment medium in the circuit and a heating device for maintaining the flow at the treatment temperature for carrying out the method according to the invention, is preferably equipped in such a way that the probe of a thermometer is arranged in the circuit of the treatment medium, which is connected to a heating controller to which a valve which changes the amount of energy flowing to the heating device per unit of time is connected, the respective position of which can be detected.
  • the heating device consists of a heating register arranged on the suction side of the fan or a gas or oil burner, the probe of the thermometer being arranged behind the heating device in the flow direction.
  • a web 1 is guided in a wide-stretched state between nozzle boxes 2 and 3 and acted upon by a gaseous treatment medium flowing essentially in the circuit.
  • a burner 5 arranged on the suction side of a fan 4 heats up the treatment medium, the temperature of which is continuously measured on the pressure side of the fan 4. Via a line 6, the temperature is given to a heating controller 7 as an actual value, to which a setpoint is additionally given via a line 8.
  • a heating valve 10 in a fuel supply line 11 is controlled via a line 9, via which the burner 5 is supplied with a corresponding amount of fuel. The respective position of the heating valve 10 is made visible by a display instrument 12.
  • the temperature of the treatment medium is thus measured in the flow direction behind the burner 5 and before the material web 1 is loaded.
  • the actual value determined in this way is compared in heating controller 7 with the setpoint, i.e. the set temperature. If the actual value is below the target value, the heating controller 7 opens the heating valve 10 and closes it again step by step if the actual value is greater than the target value.
  • a specific valve position of the heater is thus assigned to a specific heat consumption of the stenter.
  • the heat balance of a drying and fixing process can be represented as follows, for example:
  • the heat quantities under a), b) and c) form the idle heat requirement of the stenter.
  • the heat quantities under d) and e) are the quantities to be applied for the goods. It can be seen from this that the drying process requires a multiple of the thermal energy of the fixing process.
  • each stenter frame is equipped with a heating valve and a display instrument that shows the valve position, the decrease in heating energy consumption over the length of the treatment section from one measuring point to the next can be determined, which indicates the point on the treatment section where the drying process ends is and the fixing process begins.
  • a display instrument 13 symbolizes the length of a schematically illustrated clamping frame 14 from seven fields 15 arranged one behind the other over the treatment path.
  • the transition point between drying and fixing treatment should lie in the tenter 14 where this is cut by a line 16.
  • the display instrument 13 shows that the fixing path 17 that is too short results from the selected web speed, which is preceded by a drying path 18 that is dimensioned too long.
  • FIG. 3 illustrates a fixing section 17 that is too long and a drying section 18 that is too short.
  • the fixing section 17 and the drying section 18 are coordinated with one another in such a way that their transition through line 16 is determined. Only in this example is the web speed optimal, so that the dry treatment time as well as the fixing treatment time is as short as possible, but also as long as necessary.
