Embodiment 1

[0026] Example 1: Human eye detection method for the discoloration function of photochromic textiles.

[0027] Specific steps are as follows:

[0028] Prepare 4 samples with a size of (5 × 10) cm. The discolored parts in the samples should have the same discoloration effect and not less than 4mm. One of them is used as a standard sample, and the remaining 3 are used as test samples. Before the test, both the test sample and the standard sample were placed in the standard atmosphere specified in GB / T 6529 for 12h.

[0029] Place the 3 test samples on a neutral gray color card, and place them under a xenon light source equipped with an AM1.5 filter. Adjust the current size and the distance between the xenon light source and the sample to simulate a solar irradiance of one. Standard sunlight, turn on the light source and illuminate the test sample for 5min.

[0030] After turning off the light source, quickly take out 3 test samples and place them in the standard color matching...

Embodiment 2

[0033] Example 2: Instrumental detection method of photochromic textile discoloration function.

[0034] Specific steps are as follows:

[0035] Prepare 3 test samples with a size of (5 × 10) cm. The discolored parts in the samples should have the same discoloration effect and be no less than 4mm.

[0036] Before the test, the test samples were placed in the standard atmosphere specified in GB / T 6529 for 10h conditioning.

[0037] First take a sample, use a hand-held spectrophotometer to measure the CIE tristimulus value of the photochromic sample under the conditions of D65 standard light source, 10° field of view, and UV off, as the standard value.

[0038] Place the above three test samples on a neutral gray color card respectively, adjust the current and the distance between the xenon light source and the sample to simulate the sunlight irradiance as a standard sunlight, and turn on the light source to illuminate the test samples for 5 minutes.

[0039] After turning off...

Embodiment 3

[0043] The difference between this example and Example 1 is that the adjustment time is 0.5h, the irradiation time is 10min, and the recovery time is 60min.

Abstract

The present invention provides a detection method for photoretically discolored textiles. It uses standard sunlight as a stimulating color change source to determine the color difference between color variants after the sun is excited and removed by the stimulating light.The color changing performance of optical discoloration textiles.The present invention solves the current detection problem of optical discoloration textiles. It can effectively test the discoloration properties of the color -changing textiles, including color variability and color -changing simulation.This method has the advantages of simple, easy operation and standardization.

Description

technical field [0001] The invention relates to a method for detecting textiles, in particular to a method for detecting the discoloration performance of photochromic textiles. Background technique [0002] With the continuous introduction of high-tech, color-changing textiles, as high-tech functional textiles with rapid development in recent years, are also endowed with higher added value and benefits because of their fashionable beauty, tasteless and non-toxic, and have good development prospects and broad application prospects. [0003] Photochromic textiles are the most widely used and most mature color-changing textiles. The samples are excited by the ultraviolet-visible light band, such as from indoors to outdoors, from the shade to the sun, and discoloration occurs. When the light disappears, it will return to its original state. color. Reversibility, fast color change, vivid color, easy excitation and wide application are the special attributes of this type of text...
