How to identify if the thread is natural mulberry silk thread?

Because the price of natural mulberry silk thread is very expensive, some merchants will sell imitation synthetic silk thread as natural mulberry silk thread. If you are not sure whether the thread you bought is natural mulberry silk thread, you can identify it through the following three methods.

1.Take a small section of the purchased silk thread and soak it in 84 disinfectant (the main component is sodium hypochlorite, and the effective chlorine content is 4%-4.9%). It can be completely dissolved within ten minutes. Only part of the dye will remain.

2.Burn it. Natural mulberry silk thread is a silk thread spit out by silkworms (a kind of insect), so it will produce the smell of burnt insects after being burnt. When mulberry silk is burned, it will produce white smoke, quickly turn into ashes, and it will naturally extinguish after leaving the fire source. The residue after burning is black and brittle granules. These black granules are very similar to the black granules produced after hair is burnt.

3.It can be identified by observing with the naked eye and touching with hands. This method requires people with certain experience to identify. Compared with synthetic silk thread, natural mulberry silk thread has a softer gloss, a more delicate and soft touch, and a certain toughness.
