What Is Mulberry Silk and Why Is It Special?

If you've ever shopped for silk products, you've likely come across the term "mulberry silk." But what exactly is mulberry silk, and why is it considered the gold standard of silk? Here's everything you need to know.

What Is Mulberry Silk?

Mulberry silk is the highest quality silk available. It's produced by silkworms of the species Bombyx mori that are fed exclusively on the leaves of mulberry trees (Morus alba). This controlled, specialized diet results in silk that is remarkably uniform, smooth, and lustrous — qualities that set it apart from all other types of silk.

The name "mulberry silk" comes directly from the silkworm's diet. The mulberry leaf is the only food source for Bombyx mori silkworms, and this exclusive diet is what gives mulberry silk its exceptional properties.

How Is Mulberry Silk Different from Other Silks?

Not all silk is created equal. Here's how mulberry silk compares to other types:

• Mulberry Silk: Produced by Bombyx mori silkworms on a controlled mulberry leaf diet. Fibers are long, uniform, and naturally white. The smoothest, most lustrous, and most durable silk available.
• Wild Silk (Tussah Silk): Produced by wild silkworms that eat a variety of leaves. Fibers are shorter, less uniform, and naturally tan or brown. Coarser texture and less sheen than mulberry silk.
• Eri Silk: Produced by Samia ricini silkworms. Heavier and more matte than mulberry silk. Often used for sustainable "peace silk" production.
• Muga Silk: Produced only in Assam, India. Has a natural golden color and high durability, but is rare and expensive.

Why Is Mulberry Silk So Special?

Exceptional Smoothness

Mulberry silk fibers are among the longest and most uniform natural fibers in the world — a single cocoon can yield a continuous filament up to 1,600 meters long. This length and uniformity creates an incredibly smooth fabric with minimal surface irregularities.

Natural Luster

The triangular prism-like structure of silk fibers refracts light at multiple angles, creating silk's characteristic shimmering appearance. Mulberry silk's long, uniform fibers maximize this optical effect, giving it an unmatched natural sheen.

Hypoallergenic Properties

Mulberry silk is naturally hypoallergenic. It's resistant to dust mites, mold, and mildew, making it an excellent choice for people with allergies or sensitive skin.

Temperature Regulation

Silk is a natural protein fiber with excellent thermoregulating properties. It keeps you cool in summer and warm in winter, making it ideal for bedding and sleepwear year-round.

Durability

Despite its delicate appearance, mulberry silk is surprisingly strong. Silk is one of the strongest natural fibers by weight. With proper care, mulberry silk products can last for decades.

What Momme Weight Means for Mulberry Silk

Momme (mm) is the unit used to measure silk fabric weight and density. Higher momme = more silk = heavier, more durable fabric.

• 16 momme: Lightweight, ideal for scarves and linings
• 19 momme: Medium weight, popular for pillowcases and sleepwear
• 22 momme: Heavier, more durable — ideal for bedding and pillowcases
• 25+ momme: Premium weight for the most luxurious bedding
