Embodiment 1

[0043] 1) The 99.5% pure copper backing material with a thickness of 1mm is placed under the sample of modern simulated aging wool fabric, and the sample surface is flat and fits the upper surface of the backing material; the pure copper backing material has a shape size of 6cm in length and 4cm in width. The modern simulated aging wool fabric sample is a modern wool fabric cut into 20cm x 5cm strips of cloth, placed flat on a porcelain tray, and then placed in an oven at 150 ° C, the tray is fixed at the same layer. In order to make the aging sample treatment effect more stable, turn the surface every other day and make parallel movements. Samples were taken out at 4d, 8d, 12d, 16d, 20d and 24d respectively to obtain heat aging samples;

[0044] 2) Place the two electrodes of the corrected resistance tester on the surface of the modern simulated aging wool sample, measure the surface resistance between the two electrodes, read the value and record;

[0045] 3) According to the su...

Embodiment 2

[0049] 1) The 99.5% pure copper backing material with a thickness of 2mm is placed under the fragment of the hemp fabric cultural relics, and the surface of the cultural relics is flat and fits on the upper surface of the backing material; the pure copper backing material has a length: 6cm, a width of 3cm. The fragments of the hemp fabric cultural relics mentioned are excavated in Henan, dating back about 2,700 years.

[0050] 2) Use a surface resistance meter to gently place the surface of the cultural relic fragment to measure the surface resistance between the two conductive strips, read the value and record;

[0051] 3) According to the surface resistance data, the surface resistance range of modern simulated samples with different aging degrees of hemp fabrics is controlled, and the aging state of cultural relics is judged;

[0052] Final embodiment 2 of the surface resistance value as Figure 2 As shown, the fragment of the cultural relics is woven with two different colors o...

Embodiment 3

[0054] 1) The 99.9% sterling silver backing material with a thickness of 0.5mm is placed under the fragments of woolen fabric cultural relics, and the surface of the cultural relics is flat and fits on the upper surface of the backing material; the shape of the sterling silver backing material is length: 5cm, width 4cm. The fragments of the wool fabric cultural relics are excavated from Xinjiang, dating from the Xiaohe period, which is about 3,800 years ago.

[0055] 2) Use a surface resistance meter to gently place the surface of the cultural relic fragment to measure the surface resistance between the two conductive strips, read the value and record;

[0056] 3) According to the surface resistance data, the surface resistance range of modern simulated samples with different aging degrees of hemp fabrics is controlled, and the aging state of cultural relics is judged;

[0057] Final embodiment 3 of the surface resistance value as Figure 3 As shown, the belt jacket is woven from w...

Abstract

The invention relates to the technical field of detection of cultural relics, and discloses a surface resistance evaluation method for the aging degree of ancient textile cultural relics, comprising: 1) placing a strip-shaped backing material under the textile cultural relics to be tested; 2) measuring the surface resistance of the textile cultural relics; 3) Compare the surface resistance value with the surface resistance of the aging degree of modern analog samples according to the material type, and determine the value range of the surface resistance value; 4) Judge the aging degree of textile cultural relics; 5) Compare the surface resistance value with modern analog samples according to the material type The corresponding relationship between the sample breaking strength retention rate and the surface resistance, according to the corresponding relationship, the fabric breaking strength retention rate achieved by the measured object can be inferred. The method of the invention can improve the surface resistance sensitivity of the sample without destroying or applying pressure to the sample, and can quickly and non-destructively judge the aging degree of textile cultural relics in combination with the corresponding relationship between the breaking strength and the surface resistance.

Description

Technical field [0001] The present invention relates to the field of cultural relics detection technology, in particular to a surface resistance assessment method for the aging degree of ancient textile cultural relics. Background [0002] Including silk fabrics, cotton fabrics, wool fabrics, linen fabrics and other textile cultural relics in the excavation and collection process of aging, due to the rarity of cultural relics, can not use the mechanical test method for fracture strength performance test, the test has the characteristics of damage, can not directly judge the textile fiber fracture strength, so it is impossible to intuitively judge the fracture strength of textile cultural relics after aging. At this stage, the application of amino acid analysis, infrared spectroscopy, microscopic magnification observation, proteomics and other means is to collect cultural relics samples, for precious cultural relics, due to their special uniqueness and non-renewable and irreplacea...
