Tips for distinguishing between real silk and rayon

May 12, 2020

Everyone knows that real silk is skin-friendly, but how can you confirm that the silk fabric you bought is authentic?


How to distinguish between real silk and rayon

The simplest point is that all "man-made" fibers generally look bright, regardless of color distribution or fiber thickness. On the contrary, some may have a small number of impurities, which is actually genuine.


Observe the gloss

The color of real silk is similar to pearls and has the characteristics of diffuse refraction to light, and the silk path is neat and orderly. Some chemical fibers are bright but pale and dazzling.


Touch by hand

The real silk is soft and delicate, and it feels full of elasticity when touched by hand. Due to the pore structure on the natural fiber, it sometimes feels "astringent and sticky". The raw materials of artificial silk, such as chemical fiber, feel stiff or slippery.


Listen to the sound with ears

Open the silk quilt, take a little fiber, knead and rub with your hands, and listen carefully. The dry silk will make a rustling sound when rubbed. "Siming" also known as "silk singing" is the unique characteristic of real silk, but neither chemical fiber nor cotton. In addition, during the friction with two fingers, the silk will generally "gather" into a thread, and the chemical fiber will slip out of the finger.


Pull test

Try to strip a little fiber from the bulk fiber. If the fiber is not only long but also closely interwoven, as if it is endless, it is difficult to pull it apart. If the fiber is shorter and thicker, it is tussah silk or quilt. If the fiber thickness is uniform and the color is single and regular, it is chemical fiber.
