The textile fiber components and content are important indexes related to the performance, cost and product care of textiles, clothes and home textiles. At present, the identification of the fiber content is incorporated into the mandatory standard in many countries, and becomes one of the contents that all the clothes and home textiles need to disclose the identification to consumers when being sold. The content authenticity of the fiber components and the content is also one of the items of various market supervision and inspection, and is the item with higher unqualified incidence in the supervision and spot inspection of various textiles.

The premise of accurately marking the fiber components and the content is the accurate measurement of the fiber components and the content, and therefore, production enterprises, detection mechanisms and national supervision centers in the textile industry need to consume a large amount of manpower and material resources to analyze the fiber components and the content. Among the most used methods, chemical dissolution quantitative analysis is used. The chemical dissolving quantitative analysis method is that a plurality of small samples are cut from the textile, the small samples are dried and weighed, then the small samples are put into different reagents, such as sulfuric acid, sodium hydroxide solution and the like, so that the small samples are dissolved, the small sample residues are filtered and dried, and the residual weight of the dissolved small samples is weighed. When the solution reagent is selected, the solution in which only one of the components is dissolved is selected as a detection reagent by contrasting the component table of the textile, and the proportion of the component can be obtained by comparing the original dry weight of the small sample with the dry weight of the residue after dissolution.

However, the operation of the conventional chemical dissolution quantitative analysis method requires manual work in the whole process, and the dissolution efficiency is low, so that the conical flask containing the reagent and the sample needs to be stirred or shaken manually and continuously.

And drying and weighing the cut sample, recording the weight of the sample before dissolution, then filling the sample into a corrosion-resistant filter bag, and marking. Several filter bags requiring dissolution testing using the same dissolution reagent are placed in the sample tank 24 and the tester is turned on. After the tester is started, water is injected into the water bath 21, and if the temperature requirement of the dissolution standard method is met, the heating pipe 211 is started to heat. Meanwhile, the dissolving reagent is introduced into the dissolving tank 22 through the liquid inlet and outlet system 4, enters the sample tank 24 through the meshes 241 on the sample tank 24, and permeates into the filter bag to be contacted with the small sample. The motor 31 is started to drive the first magnetic block 32 to rotate, and the second magnetic block 33 is driven to rotate under the action of magnetic force. Because the rotating block 23 connects the second magnetic block 33 with the sample tank 24, when the second magnetic block 33 is driven by magnetic force to rotate, the rotating block 23 and the sample tank 24 rotate together with the second magnetic block 33, and at the same time, the stirring block 231 on the rotating block 23 stirs the dissolving reagent in the dissolving tank 22, thereby increasing the dissolving speed of the selected component in the small sample.
