Light aging test frame for fugitive dye of silk fabrics and light aging test method

Abstract

The invention discloses a light aging test frame for a fugitive dye of silk fabrics. The light aging test frame comprises a base with a detection substance placing area, wherein a vertical column is arranged on the side edge of the base; a movable rod and a light source traveling device are connected to the vertical column; the movable rod can move up and down; an input optical fiber of a miniature fiber optic spectrometer is connected to the upper part of the light source traveling device; the side edge of the light source traveling device is connected with an output optical fiber of the miniature fiber optic spectrometer. According to a light aging test method using the light aging test frame for the fugitive dye of the silk fabrics, the miniature fiber optic spectrometer is used as a main body, and the input illumination intensity is changed by sliding of the movable rod in the light aging test frame, so that the fading degree of the fugitive dye of the silk fabrics is changed along with the change of the input illumination intensity, and the aging degree of the fugitive dye of the silk fabrics under the illumination is judged. The light aging test frame has the advantages that the wavelength range is wide; the detection speed is high, and the aging time is short.

Description

technical field

[0001] The invention relates to a light-aging test method of silk fabric fading dyes and a light aging test frame, in particular to a light-aging test method of silk fabric light-fading dyes based on micro-optical fiber spectroscopy technology and a light aging test frame used in the method. Background technique

[0002] Silk is a symbol of ancient Chinese civilization. The ancient Chinese silk industry has embroidered a glorious chapter for Chinese national culture and made an indelible contribution to the development of human civilization in the world. Unearthed silk fabrics have become fragile due to various environmental factors. How to protect cultural relic silk fabrics has become an important topic for museum researchers. When silk fabrics are exhibited, they are affected by temperature, humidity, light, etc., and light will not only cause the dyes of silk fabrics to fade, but also cause the strength of silk fabrics to weaken. However, silk fabrics mus...
