What Is Mulberry Silk? Premium Silk Characteristics and Buying Guide

Aug 22, 2025 townssilk

What Is Mulberry Silk

Mulberry silk is made from the long silk fibers spun by domesticated silkworms (Bombyx mori). In commercial farming, these silkworms are fed exclusively on mulberry leaves, resulting in finer, more uniform fibers with a soft, lustrous sheen. For centuries, mulberry silk has been the premium material of choice for luxury silk pillowcases, duvets, and garments.

Compared with wild silk or other silk types, high-quality mulberry silk is naturally whiter in color and has a smoother touch, making it ideal for direct contact with skin.

Natural Benefits of Mulberry Silk

  • Skin-Friendly & Smooth – The fiber surface is smooth and soft, reducing friction with skin and hair to prevent frizz and sleep creases.
  • Breathable & Insulating – Cool and breathable in summer, warm and insulating in winter, providing comfort all year round.
  • Hypoallergenic – Rich in silk protein, resistant to dust mites, and friendly to sensitive skin.

Mulberry Silk vs. Regular Silk

The term “silk” is a general category that includes silk from different silkworm species, such as mulberry silk and tussah silk (wild silk). They differ significantly in origin, fiber structure, appearance, and application:

Comparison Criteria Mulberry Silk Wild/Other Silk
Source Farmed silkworms fed on mulberry leaves Semi-wild or wild silkworms, varied diet
Fiber Diameter Fine and uniform, smooth surface Coarser, with a slightly fuzzy texture
Color & Luster Naturally white, soft sheen Yellow-brown, duller sheen
Dyeability Easily dyed into a variety of colors Often used for darker shades
Common Uses High-end bedding, apparel Warm duvets, decorative items
Hand Feel Soft, smooth, excellent drape Stiffer, with a granular feel

How to Identify Quality Mulberry Silk

  • Fiber Type – Premium mulberry silk often uses continuous long fibers with a smooth surface.
  • Grading – Rated from A to 6A, with 6A being the finest and most uniform.
  • Momme Weight – 19 momme for lightness, 22 momme for durability, 25 momme and above for luxury items.
  • Luster & Feel – Soft, warm sheen with a smooth, elastic texture.
  • Burn Test – Burns slowly, shrinks, leaves powdery ash, and smells like burnt hair.

Care Tips for Mulberry Silk

  • Washing – Use silk-specific detergent, hand wash in cold water, or use a gentle machine cycle for silk.
  • Drying – Air dry in a cool, shaded place; avoid direct sunlight.
  • Storage – Keep dry and avoid contact with chemicals.

Summary

With its delicate texture and breathable, skin-friendly qualities, mulberry silk is one of the most comfortable types of premium silk. When shopping for a silk pillowcase or duvet, mulberry silk should be your top choice.

If you value sleep quality and skin health, the Townssilk Mulberry Silk Bedding Collection is a worthwhile long-term investment.
