3 ways to distinguish true silk from false silk
1. look at the chemical reaction
the real silk into 84 disinfectant, about 10 minutes will disappear and dissolve, and chemical fiber or kapok and other fake silk is insoluble in this solution. The silk can be extracted from any corner of the test, not just the silk of the test mouth!
2. look at the fiber toughness
the real silk has good ductility and continuous pulling, while the chemical fiber and kapok pretend to be silk pulling will be broken and scattered.
3. look at the burning state
the true silk burns white smoke, accompanied by the smell of burnt hair, after burning is loose gray, ash a pinch will be broken. Chemical fiber fake silk, when burning black smoke, smell pungent and drip-drawn phenomenon, residue for glassy black brown hard ball, not easy to crush.
4 ways to distinguish silk from good

2. look at the appearance
the appearance of high-quality silk has a pearl-like color, and has the performance of diffuse refraction of light. Clean and few impurities, silk road orderly. The poor quality of silk is often due to the addition of chemicals such as bleach, so that its appearance is pale, not shiny and moist, more impurities, silk road chaos.
