Mulberry silk soaked in water can indeed serve as a method for identifying authenticity. True mulberry silk has good moisture absorption. When in contact with water, it quickly absorbs moisture and becomes moist. In contrast, synthetic fibers or other imitations have poor water absorption and often only have a moist surface after contact with water. Mulberry silk is composed of natural proteins, so it will dissolve in water under certain conditions, requiring a certain amount of time and temperature. If mulberry silk is placed in water at room temperature, it will not immediately dissolve, but after prolonged soaking, it will gradually lose its strength and dissolve. Synthetic fibers, on the other hand, usually have good stability to water and are not easily soluble.

In addition, after soaking mulberry silk in water, its texture becomes softer and smoother. This is because after the mulberry silk fibers absorb moisture, the friction between the fibers decreases, making the feel more comfortable. Imitation products may have a rough feel or remain the same.

Another method is to randomly draw out a few strands of silk and wet them with water. If they break from the wet area, it is artificial silk, and if the broken ends are in a fluffy shape of varying lengths, it is real silk.

It should be noted that this method requires a certain amount of experience and professional knowledge, which may be difficult for ordinary consumers to make accurate judgments. Therefore, when purchasing mulberry silk products, it is best to choose a reputable merchant and check the relevant quality certification.
