Near infrared rapid non-destructive detection method for textile components

The invention discloses a near infrared rapid non-destructive detection method for textile components, comprising the following steps: firstly turning on a power, switching on a near infrared spectrometer and detecting the state of the near infrared spectrometer, when detecting a textile sample, putting the sample to be detected in an accessory, determining the detection thickness of the sample according to prompts of an LED indicator light on the accessory; exposing the surface of the sample to be detected to the light emitted by a light source, and forming diffuse reflection in the interior, receiving diffuse reflection light by a detector and transiting the received diffuse reflection light into digital signals, saving the digital signals in a computer, selecting an already established model to calculate spectral signals, displaying the calculated fiber blending ratio of the sample to be detected, taking out the detected sample, cleaning the accessory, and preparing for a next detection.
