To identify silk fabrics and tell the difference between pure silk and rayon, you can try the following steps:
1. Observe the luster: Silk has Natural luster, while rayon often appears more sparkly and lustrous. When viewed in natural light, silk will reflect a soft sheen, while rayon may have a brighter sheen.
2. Touch feel: Silk feels very soft, smooth and cool, and usually gives people a special sense of comfort. In contrast, rayon may be rougher to the touch or may not have the special feel of real silk.
3. Singeing test: Place a small amount of fabric fibers (preferably at the corners of clothes) in a non-flammable container and ignite it. Silk fibers will burn quickly when caught on fire, with a burning smell similar to hair, and a cloud of ash will remain. Rayon burns more slowly, smells like burning plastic, and leaves a brittle, hard ball.
4. Look at the thread ends of the yarn: disassemble a small section of yarn and observe its cross section. Silk threads are flat and smooth, while rayon threads may look more obvious and irregular in shape.
These methods are all based on sensory observation and experiments to determine the differences between real silk and rayon. However, due to factors such as textile quality inspection standards and blending of different brands and manufacturers on the market, it may sometimes make identification more difficult. If you need more accurate results, it is recommended to conduct testing and confirmation through a professional laboratory or textile certification agency. .
