5. Early warning of the latest counterfeiting methods
According to the 2023 quality inspection report, new fraud methods include:
- "Sandwich layer" process: the upper and lower layers are made of real silk, and the middle is filled with chemical fiber
- "Core-spun silk" technology: chemical fiber wrapped with thin layer of silk
- Add weight gainers: use calcium chloride, etc. to gain weight
It is recommended that consumers ask merchants to provide a testing port (at least 30cm), and each layer of fibers can be randomly selected for testing. Keep the proof of purchase and report quality problems to 12315 in a timely manner. By comprehensively applying these methods, you can effectively avoid consumer traps and purchase truly high-quality silk products.
