3. Mulberry silk

Mulberry silk is a kind of continuous long fiber, also known as "natural silk", which is solidified by silk liquid secreted by mature silkworms when they cocoon. Mulberry silk is the best raw material for making silk quilts. The silk quilt made of mulberry silk is not only soft, close-fitting, warm and breathable, but also has many health functions for human body because of its green and healthy characteristics. Moreover, the hygroscopicity of silk is 1.5 times that of pure cotton and 1.8 times that of wool, which can keep the balance of skin moisture and has a good curative effect on the elderly with dry skin.

Tussah silk has good heat resistance, high toughness, thick fiber, moisture resistance, acid resistance and alkali resistance, which is far superior to mulberry silk quilt. Tussah silk is very good as a real silk carpet. But as a quilt, tussah silk is not as smooth, warm and breathable as mulberry silk. Moreover, there is a phenomenon that many manufacturers will bleach the squeezed silk in order to make it look better, which is not good for people's health.
