Problems solved by technology

Due to the conventional detection method or because of complicated operation, difficult sample preparation, or because of harsh experimental conditions, the accuracy is difficult to guarantee, or because of the interference of subjective factors that cannot be ruled out, or because the final distinction effect is not obvious, it has not been possible to achieve the final determination of the gross. Fast, accurate identification of fibers

Embodiment example

[0035] The application of the patent of the present invention will be described in detail below by taking fox fur, raccoon fur, mink fur, rabbit fur and sheep fur as examples, but the scope of the patent of the present invention is not limited to the following examples.

[0036] 1) Establishment of calibration model

[0037] First, the spectrum of a known sample is collected as figure 1 , all kinds of fur cannot be classified from the original image, and then the original spectrum is preprocessed by first-order derivation and mean centering, and then the SIMCA classification model is established, and the established model is verified. The verification results are as follows figure 2 , 3 , 4, 5, 6. From the results in the figure, it can be seen that the classification effect of fox fur, raccoon fur, mink fur, rabbit fur and sheep fur is very good.

[0038] 2) Practical application

[0039] Using the method and equipment of the present invention to classify 18 samples of kno...

Abstract

The invention discloses a rapid nondestructive qualitative analysis method and device for fur. A fur detection device is developed based on molecular spectroscopy and chemometrics method, and rapid classification detection of fur is realized by spectral acquisition and data processing.

Description

technical field [0001] The invention discloses a method and equipment for fast and non-destructive qualitative classification of fur, in particular to a method and equipment for fast and non-destructive qualitative classification of fur by near-infrared spectrum. Background technique [0002] With the improvement of people's living standards, people pay more attention to clothing, and the demand for high-grade fur clothing is increasing. my country is rich in wild animal resources and various in variety. my country is the center of fur production, processing and consumption in the world, and is a big country in fur industry. In the market, unscrupulous manufacturers are driven by huge profits to sell imitation, counterfeit or even counterfeit fur products. Ordinary consumers do not have the ability to identify the authenticity of fur. However, the current fiber detection system lacks detection standards for fur fibers. Urgent research is needed to establish a set of practic...
