Embodiment 1

[0028] A non-destructive testing method for dyes on textile cultural relics, which adopts the following steps:

[0029] 1) Connect the deuterium lamp-halogen tungsten lamp combination light source, the miniature fiber optic spectrometer, the diffuse reflection device and the portable computer;

[0030] 2) Open the spectrometer software, adjust the angle and height of the fiber optic probe, and use a standard white board to calibrate the spectrometer;

[0031] 3) Place the yellow cultural relic sample at a distance of about 1cm below the fiber optic probe, adjust the integration time according to the strength of the spectral signal, and obtain the ultraviolet-visible reflection spectrum of the dye;

[0032] 4) Save the spectrogram of the sample to be tested and compare it with the dye standard spectrum. The results show that the characteristic absorption peaks are located at 344nm and 438nm, and the species of the dye is identified as Phellodendron amurense.

Embodiment 2

[0034] A non-destructive testing method for dyes on textile cultural relics, which adopts the following steps:

[0035] 1) Connect the deuterium lamp-halogen tungsten lamp combination light source, the miniature fiber optic spectrometer, the diffuse reflection device and the portable computer;

[0036] 2) Open the spectrometer software, adjust the angle and height of the fiber optic probe, and use a standard white board to calibrate the spectrometer;

[0037] 3) Place the red cultural relic sample at a distance of 0.5cm or 1.5cm below the fiber optic probe, adjust the integration time according to the strength of the spectral signal, and obtain the ultraviolet-visible reflection spectrum of the dye;

[0038] 4) Save the spectrogram of the sample to be tested and compare it with the dye standard spectrum. The result shows that the characteristic absorption peak is located at 520nm, and the species of the identified dye is hematoxylin.

Abstract

A non-constructive detection method for dyes on textile antique comprises following steps: (1) connecting a composite light source composed of deuterium lamp and halogen tungsten lamp, a micro fiber optic spectrometer and a diffuse reflection device to a portable computer; (2) running the spectrometer software, adjusting the angle and height of the optic fiber probe and correcting the spectrometer with a standard white board; (3) putting the sample to be detected under the optic fiber probe ( the distance is about 1 cm), adjusting the integration time according to the strength of the spectral signals and obtaining a ultraviolet-visible spectrum of the dyes; (4) saving the spectrogram of the sample to be detected, comparing to a standard dye spectrogram, and identifying the sorts of the dyes. Compared to the prior art, the non-destructive detection method has the advantages that: the method is suitable for dye detection under various environments, the sorts of dyes can be identified without sampling, categories of various natural dyes can be precisely identified by the method, and the method also provides basic data for the color protection of textile antiques.

Description

technical field [0001] The invention relates to a non-destructive detection method for dyes on textile cultural relics, and belongs to the technical field of cultural relics analysis and detection methods. Background technique [0002] Various dyes on textile cultural relics reflect the exquisite printing and dyeing technology in ancient my country and embody the innovative spirit of the Chinese nation. There are many methods currently used in the detection of textile cultural relic dyes, including thin layer chromatography, high performance liquid chromatography, laser Raman spectroscopy, infrared spectroscopy, etc. For the well-preserved handed down textiles, we cannot obtain enough samples for the detection and analysis of the above methods. Therefore, it is extremely important to develop a method for the non-destructive detection of dyes on textile artifacts. Contents of the invention [0003] The purpose of the present invention is to overcome the deficienci...
