Blended fibers are generally blended with more than 2 types of fiber materials. For example, some clothing labels write 30% cotton, 60% polyester fiber, 10% silk, etc. in the component label column. This is the mixed fiber material. Clothing made from 3 fiber materials, chemical fiber and silk. To obtain the result of the component content of these mixed fibers requires a method that is specifically used to detect the fiber content.
Actually with regard to fiber content The test plan has always represented a worldwideProblem. At present, there is no instrument that can quickly detect the content of different fibers in the mixed fiber. There are usually two methods for checking the fiber content. One of them is chemical methods, one is Microscopy.
1. Chemical Method is a method of dissolving a specific fiber in a specific solvent. The sample is previously weighed and placed in another solvent, and then dried to test the weight change to obtain fiber content data.
Second, microscopy consists of making a specific sample of mixed fibers and then using aMicroscope to zoom on the sample. Different fiber materials have different colors and surface characteristics, so it is easy to count the number of different fiber materials in the sample after distinguishing several different fibers. After the statistics are completed, data calculation can be performed to obtain the content data of different fiber materials in the mixed fibers.
However, this method is extremely slow in detection as the test sample may contain thousands of fibers that need to be counted individually. When the digital(Semi-Automatic)Fiber Fineness Analyzer for testing requires specialized personnel to analyze data statistics to perform, and a test often takes 2-3 If you use a fully automaticWhen using fiber fineness analyzer, the computer can automatically count the number of different fibers, which can greatly improve the test efficiency, but it also takes half an hour, and Automatic Fiber Fineness Analyzer is very expensive, and customers can follow the test plan choose their own needs.
