There were several institutions that could appraise mulberry silk. Among them, the China Science and Technology Testing Institute and the China Analysis Research Institute were professional third-party testing institutions. They had the qualifications of the CMA-CNAC, professional equipment, and talents. They could conduct the testing and identification of mulberry silk. Zhongke Testing provided a full range of testing and appraisal services at a reasonable cost, and issued professional test reports according to national and industry standards. The research and analysis center of the China Research Institute could also conduct mulberry silk testing. It had the CMA-testing qualification, complete testing equipment, and scientific and reliable data. These organizations could provide customers with accurate mulberry silk identification services.
The quality inspection report of mulberry silk needed to test both the filling (silk) and the fabric. The precautions for the filling included the type, length, content, impurity content, and environmental indicators (such as the pH value) of the silk. The type of silk should be mulberry silk, and the length should be long silk cotton or medium-long silk cotton. The content must meet the requirements of first-class and first-class products, and the impurity rate and oil content should also be limited accordingly. The testing items for the fabric included appearance quality, composition, formalin content, PH value, nitrogen, odor, oil content, moisture regain, weight, compression resilience, contraction rate, and color firmness. For specific testing standards, you can refer to the relevant standards such as "GB/T2910-2009" and "GB/T32016-2015". However, the given information did not provide specific quality inspection report results, so it was impossible to give a specific answer.
Mulberry silk quality inspection report was a report on the quality of mulberry silk products. The quality inspection report mainly focused on two aspects: the filling (silk) and the fabric. In terms of fillings, one needed to pay attention to the type, length, content, impurity content, and environmental indicators of silk (such as the PH value and the content of formalin). The filling of the mulberry silk quilt should be mulberry silk, and the silk content of high-grade and first-grade silk quilts must reach 100% and be long silk cotton or medium-long silk cotton. The silk content of qualified silk quilts should reach more than 50%. In terms of fabric, one needed to pay attention to the composition and content, environmental indicators (such as the PH value and the content of Formalide), and the content of aromatic aromatic amine that could be decomposed after dyeing. The quality inspection report could be tested by the testing institution. The testing period was usually 3-10 working days. The testing fee needed to be quoted according to the specific project and the complexity of the experiment. The testing range included silk quilts, mulberry silk, silk nightdresses, silk protein, silk rope, silkworm silk, tussah silk, silk fabrics, silk fibers, and silk fabrics. For testing standards, you can refer to the following standards: "Silk Quilt","Determination of Silk Acid","Silk Performance and Test Terminology","Silk and synthetic fiber screens", and "Silk and synthetic fiber screens".
The easiest way to test mulberry silk was to observe its appearance and feel. The appearance of mulberry silk should be shiny, soft to the touch, clear silk lines, regular patterns, no obvious impurities and defects. In addition, he could use the fire method to test it. A small section of silk was lit with a lighter. When the real silk burned, it would emit white smoke. It was flame resistant and would automatically extinguish after leaving the fire source. The ash was grayish black and very brittle. It would turn into powder after pinching it. It could also be distinguished by touching it. Mulberry silk felt smoother and easier to stick to the hand, while tussah silk felt a little astringent and was not easy to stick to the hand. Finally, he could use the static electricity method to pull out some of the silk quilt, fold it up and rub it quickly. If the silk was a poor conductor of electricity, it was not easy to generate static electricity, so it would not attract small paper scraps.
There were a few third-party testing organizations that could test mulberry silk. Among them, Beijing Zhongke Guangxi Science and Technology Research Institute was a third-party testing organization with the CMA-certified qualification. It could provide testing services for mulberry silk, silk quilts, mulberry silk fabrics, and other mulberry silk-related products. The institution had a team of doctors and imported testing equipment to ensure the accuracy of the data. In addition, their test report also supported the verification of the authenticity of the QR code. In addition, the material testing organization of the Institute of Chinese Medicine could also provide silk testing services. They were a CMA-certified organization with complete laboratory equipment and a strong research team. These institutions could issue approved silk test reports.
Mange mites are quite minuscule. They're usually less than 1 millimeter long. Their small size is one reason why detecting and treating mange can be challenging.
