- the invention also relates to a method for recognizing properties a textile in a device for treating textiles, that's the characteristics of claim 14 contains.
- electromagnetic radiation i.e. H. Radiation in UV
- the textile is processed in some way in the treatment device, for example wetted with a liquid medium, dried, spun, strengthened, dry cleaned or otherwise Way changed.
- the treatment device is a laundry treatment device, for example a washing machine, a tumble dryer, a spin dryer, a lack of laundry, a machine for dry cleaning or Dyeing of textiles. If the term "laundry item" is used below, then to always understand any kind of textile medium.
- a transmitting element in the sense of the invention is any radiator, the electromagnetic one Emits radiation, for example an incandescent lamp, a halogen lamp, a Mercury vapor lamp, a light emitting diode, a laser diode, a gas laser and the like.
- Transmitters that emit a narrow-band spectrum are particularly suitable, or transmitters that produce monochromatic light.
- Monochromatic ones are suitable or narrowband transmitters in connection with one or more receivers, whereby these can be broadband, provided that they are only the bandwidth of the transmitter or radiation emitted by the transmitters.
- broadband radiators can be used and use assigned wavelength-selective receivers.
- wavelength selective Receivers can also use broadband transmitters and / or receivers if narrow band filters are assigned to either the transmitters or the receivers are.
- a plurality of transmission elements is preferably also used, wherein these either different spectra or monochromatic light different Generate wavelengths.
- the reception elements are corresponding to the transmission elements adjusted, this either a certain band within that of the transmitting element or detect the transmission radiation emitted by the transmission elements, or exactly capture the wavelength emitted by the transmitter element or elements, if this or these are monochromatic light sources.
- Photodiodes or phototransistors are therefore particularly suitable.
- the received Light must be selected according to the wavelength. This can be done using a Filters, a prism or a diffraction grating.
- the light emitted by the transmitting element or elements is emitted by the Textiles, especially laundry items, are partly absorbed, but partly reflected or transmitted.
- the reflected light is primarily for detection suitable because the transmitted light only a small fraction of the transmitted radiation and the proportion of the transmitted with increasing thickness of the textiles Radiation decreases sharply.
- spectra reflected by the textiles from a transmitted spectrum or wavelengths can be inferred from the properties of the textiles. This also applies for the transmission spectra.
- the spectra are either over a specific one spectral range evaluated or only at certain frequencies or wave numbers.

H. their chemical composition from different fibers, e.g. cotton, wool, silk, synthetic fiber, or their type of tissue as well as temporary properties that are characterized by the Treated by certain media. Wetting is particularly relevant here by water or an organic solvent, by alkali or by treatment by starch or other equipment.
- the evaluation circuit obtains a signal from the received signals, which either is of immediate importance to the operator or for the further treatment of Textiles is relevant. For example, a signal can be obtained to present the operator to incorrectly program the treatment device.
- the evaluation circuit wins from the received one electromagnetic radiation, for example in the IR range, information about the type of textile, for example silk, and gives an optical or acoustic signal, if provided the operator sets a temperature at which silk would be damaged. In another Fall will automatically heat the washing machine to a temperature above the temperature permitted for silk and prevented by the evaluation circuit Program carried out based on the properties of the laundry drum Textiles take care so that none of the textiles are damaged, discolored etc.
- the detection of temporary properties of textiles is taken into account according to a particular embodiment of the invention, treatment in the washing machine adapted to the desired residual moisture or the tumble dryer.
- the operator has a certain residual moisture has been set during the spinning or drying process continuously or at certain intervals, the respective moisture status based on the electromagnetic radiation reflected and / or transmitted by the textiles recorded and from this a remaining running time of the spinning or drying program calculated.
- the spinning or drying canceled.
- the level or the loading of a laundry treatment machine can also be to capture. This happens, for example, when the machine is being filled, if each item of laundry has a sensor, preferably a plurality of Sensors are detected so that there is information about the textiles can determine the area occupied within the laundry drum. In the volumetric determination of the drum level are those of the Reflections caused by the drum rear wall are taken into account.
