what is mulberry silk made of

Mulberry silk is made from the natural protein fiber produced by Bombyx mori silkworms, which are fed only white mulberry leaves. The silk comes from the cocoons they spin, and it is a real animal-derived silk fiber, not a synthetic fabric.

Quick Scoop

• Source: cocoons of the mulberry silkworm, Bombyx mori.

• What it’s made of: long, fine protein filaments created by the silkworm.

• Why it’s special: the mulberry-leaf diet helps produce a very smooth, uniform, strong silk fiber.

In plain English

If you see “mulberry silk” on bedding, clothing, or pillowcases, it means the fabric was made from silk threads harvested from silkworm cocoons, then spun or woven into a textile. It’s considered one of the highest-quality types of silk because the fibers are especially fine, soft, and consistent.

Bottom line

Mulberry silk is basically silk protein from silkworm cocoons , specifically from silkworms raised on mulberry leaves.
