Problems solved by technology
[0005] In the existing copper ion adsorption method, the adsorption amount of damaged wool to copper ions is obtained by measuring the loss of copper ions in the solution. In this way, the test results often cannot accurately reflect the degree of wool damage. The reasons are: (1) The test process involves steps such as soaking the wool in a solution containing copper ions, pulling out the wool, measuring the concentration of copper ions in the solution, and calculating the loss of copper ions. The error in the test results may be relatively large due to differences in human operations, for example, When the wool is pulled out, part of the solution will be adsorbed, and the copper ions in this part of the solution are not adsorbed due to the damage of the wool, so the error of the test result is relatively large; (2) because the copper ions adsorbed by the wool are relatively The amount of copper ions in it is small, so the error in measurement and calculation is relatively large

Abstract
The invention provides a method for detecting a damage degree of wool, which detects the damage degree of the wool by measuring adsorption capacity of the damaged wool to copper ions. In comparison with the prior art, the method is characterized by comprising the following steps: 1) dividing the damaged wool in a damaged textile into a single line to serve as a sample to be detected, immersing the sample to be detected in a solution containing the copper ions, and then rinsing and stoving the sample to be detected; 2) directly measuring the content C1 of the copper ions in the sample to be detected after the step 1); 3) taking a single line of the undamaged wool as a check sample; 4) directly measuring the content C2 of the copper ions in the check sample; and 5) calculating a value of C1-C2, and taking the value as the adsorption capacity of the damaged wool to the copper ions. The method provided by the invention has the technical advantage that the test result can reflect the damage degree of the wool more accurately.
Description
technical field [0001] The invention relates to a fabric damage detection technology, in particular to a method for detecting wool damage. Background technique [0002] In the process of dyeing and finishing, wool fiber damage is a potentially serious problem, which exists in any wool processing operation, and can cause huge losses to the producer. Therefore, it is necessary and practical to establish a simple and feasible detection method for the damage degree of wool fiber for enterprises to monitor the damage of wool products. [0003] Compared with undamaged wool samples, wool damage is characterized by rough handle, yellowing, and color change. These phenomena are actually the appearance of severe damage to the peptide bonds or disulfide bonds on wool fibers. During the processing of wool fiber or fabric, such as strong acid carbonization, alkali scaling finishing, dyeing, etc., the protein main chain and various amino acid side chains are prone to peptide bond hydroly...
