Abstract

A device for detecting a mixture ratio of two components of a textile fabric contains a radiation source for transmitting electromagnetic radiation in a spectral band in the direction of the textile fiber structure, a radiation sensor for receiving at least a part of the electromagnetic radiation, and a spectral filter with spectral properties in the spectral band for filtering at least one part of the electromagnetic radiation. The transmittance of the spectral filter in the spectral band has at least one local maximum and at least one local minimum. The spectral properties of the spectral filter in the spectral band are adapted to the spectral properties of the radiation source and each of the two components such that a radiation intensity received by the radiation sensor is a monotonous function of the mixture ratio of the two components. The device is simple in design and allows the use of spatially resolving imaging radiation sensors.
