The Difference Between Mulberry Silk and Tussah Silk, Explained Clearly from Source to Use

Mulberry silk and tussah silk are both natural silks, but they do not come from the same source. Mulberry silk is spun by domesticated silkworms, which feed on mulberry leaves, and it is the main traditional type of silk in our country. Tussah silk, on the other hand, comes from tussah silkworms that feed on oak leaves and are mostly reared in the mountainous areas of the north, with relatively lower output.

The two differ quite noticeably in appearance and feel. Mulberry silk is naturally white in color, with long, fine fibers, a soft luster and a smooth feel, and the fabric woven from it is delicate and close-fitting. Tussah silk is originally pale yellow or yellowish brown, with coarser fibers and greater stiffness, and it feels slightly rough, but it has better loft and breathability.

In terms of use, mulberry silk is mostly used to make high-end silk fabrics, silk scarves, sleepwear and silk quilts, with an emphasis on comfort and drape. Tussah silk is better suited to silk quilt fillings, outerwear fabrics or blending with other fibers, and it performs well in durability.

When buying, you can make a preliminary judgment by color and feel, and silk that is unusually stark white or yellowed deserves extra caution. It should be noted that both are protein fibers and both give off an odor similar to burning hair when burned, so it is hard to distinguish them by the burn test alone; when purchasing, you should pay more attention to the product labeling and test reports. Overall, mulberry silk is delicate and smooth and usually more expensive, while tussah silk wins on durability and affordability, so just choose according to your own needs.
