Abstract:
      Effects of fabric testing thickness,equipment running speed,scan integration time and scan times on the online near infrared detection of equipment were discussed by using a self developed “high efficiency identification and sorting device for the main components in fiber products”.The online near infrared spectrum was compared with the offline spectrum acquired using a raster type near infrared spectrometer.Although the resolution of the online near infrared spectrum of each kind of fabric was reduced,there were obvious characteristic absorption peaks,and the repeatability for the acquired spectrum was good,which indicated that the device could be used for online identification and sorting of fabrics.The best detection conditions were as follows:the test thicknesses for the tight woven fabric samples and the loose knitted fabric samples:1 mm or more and 2.5 mm or more,respectively,the equipment running speed:0.41 m/s,scan integration time:1 millisecond(ms),and the scan times:10 times.The test conditions obtained provided a reference for the online detection of the subsequent fiber fabric.
