Is Mulberry Silk Real Silk? (Quick Answer)

Yes — mulberry silk is real silk, and it’s widely considered the finest type. Sourced from silkworms fed only mulberry leaves, it produces long, smooth fibers with a luxurious feel and natural sheen. It’s breathable, hypoallergenic, and ideal for pillowcases that protect hair and skin.

 

When you find mulberry silk pillowcases or mulberry silk bedding, you might wonder if you're really getting genuine silk. The good news is that mulberry silk is real silk. In fact, it's some of the highest-quality silk you can get.

Purchasing this kind of silk fabric means you're getting the softest and smoothest silk available. Mulberry silk is a natural fiber, which sets it apart from synthetic alternatives (satin) and makes it an eco-friendly choice.

Knowing more about this kind of pure silk can help you appreciate all of the benefits it offers. The fiber type is what distinguishes real silk, like mulberry silk, from synthetic satin—satin refers to the weave, while mulberry silk is prized for its natural fiber composition.

Check out the following information about pure mulberry silk, including its history and properties.

Where Does Mulberry Silk Come From?

Mulberry silk has been around for thousands of years. A 2022 study published in Heliyon states that this natural silk started being produced in China more than 5,000 years ago. Find out more about the fascinating history of silk as an ancient tradition.

Where do these silk fibers come from in the first place? They're from the cocoons of the Bombyx mori moth.

When these moths are still in caterpillar (silkworm) form, they eat a steady diet of white mulberry leaves from the mulberry tree. The cocoons they create end up having long strands of pure white fibers. Silk harvesters gather these strong strands and weave them into silk fabrics for pillowcases, sheets, and other products.

6 Reasons Mulberry Silk Is Unique 

Mulberry silk is considered the best quality silk for many reasons. This natural silk offers some great benefits in terms of its appearance, quality, and strength.

1. Gorgeous sheen

Pure mulberry silk has a beautiful sheen that gives it a lustrous look. Whether it's used for pillowcases or loungewear, it always provides a touch of luxury.

2. Smooth texture

This type of silk also has a super soft texture that's smooth to the touch. Sleeping on a mulberry silk pillowcase or wearing a robe made from this natural fabric feels soothing on your skin.

3. Impressive strength

While mulberry silk strands might seem delicate, they're actually incredibly durable. Each long strand of this silk offers a ton of strength that helps it stay in good condition.

4. Hydrating and cooling

Mulberry silk is also good for your skin and hair. Its hydrating properties mean you'll have a lower risk of having dry hair and skin. It also has a cooling effect, which is ideal for better beauty sleep. A 2012 study in the Journal of Physiological Anthropology found that the right thermal environment helps improve sleep quality.

5. Moisture wicking

Mulberry silk also has moisture-wicking properties. A 2012 study in Frontiers in Life Science states that mulberry silk's proteins allow it to easily absorb moisture and release it. This helps keep you from getting sweaty while trying to sleep.

6. Hypoallergenic

With mulberry silk being hypoallergenic, you also don't have to worry about having an allergic reaction to this fabric. Instead, this silk feels comfortable and cool against your skin.

Mulberry Silk vs. Other Types of Silk

Mulberry silk isn't the only type of silk out there, but they're not all created equally. The others, known as eri silk, muga silk, and tussar silk, have different appearances, textures, and properties. How do these other materials compare to mulberry silk?

 

Rolled silk fabrics in light and dark purple shades on pink surface
Silk Type Appearance Texture Weight Ideal Uses
Mulberry Naturally white, uniformly colored Smoothest, softest Lightweight Bedding, pillowcases, versatile
Muga Brownish-gold Soft (less than mulberry) Lightweight Apparel, traditional garments
Eri Reddish, white, or off-white Wooly, like cotton Heavier Apparel, eco-textiles
Tussar Deep gold, uneven coloring Rougher Lightweight Saris, traditional wear

Bedding and pillowcases are ideal uses for mulberry silk because it enhances the comfort and appearance of the bed. Its softness, durability, and natural sheen make the bed look luxurious and inviting, which is why mulberry silk is a popular choice for luxury bedding.

Appearance

Mulberry silk is the only silk type with a naturally white color. Mulberry silk is often woven in a charmeuse weave, which gives the fabric a luminous, smooth front and a matte reverse, making it especially desirable for luxury bedding and apparel. Satin weave is a another weaving technique commonly used for silk fabrics, contributing to its shiny look.

Muga silk has a brownish-gold color, while eri silk can be reddish, white, or off-white. Tussar silk has a deep gold color. Unlike mulberry silk, which is a uniformly colored fabric, tussar tends to have uneven coloring.

Texture

Mulberry silk offers the smoothest, softest texture. Eri silk's texture is more wooly, like cotton, while tussar silk is rougher. Muga silk has a soft texture, but it doesn't match mulberry silk's softness.

Properties and Uses

Mulberry is lightweight, like tussar and muga silk. Eri silk tends to be heavier. The ideal uses of these silks also differ. Mulberry silk is the most versatile, making it a good choice for bedding, pillowcases, and other items. Its many properties, from cooling effects to hypoallergenic properties, set it apart from other silks.

Common Myths and Misconceptions About Mulberry Silk

Despite being a real silk, misconceptions about mulberry silk are still around. What are a few of these myths?

Myth: Mulberry silk is slippery

It's soft and lustrous, but not as slippery as satin. Mulberry silk won't catch on your skin either as satin and cotton can.

Myth: Mulberry silk needs to be dry cleaned

You can wash your mulberry silk pillowcase in your washing machine or by hand. No need to go out of your way to bring your mulberry silk items to the dry cleaners.

Myth: Mulberry silk is too delicate and won't last long

Mulberry silk might seem like it has a short lifespan, since it's so soft and lightweight. That's not the case, though. The durability of mulberry silk means it lasts for a long time, even with regular washing.

Frequently Asked Questions (FAQ) About Mulberry Silk

Is mulberry silk as good as silk?
Yes—mulberry silk is real silk and is considered the highest quality silk fabric. Spun from uniform silk fibers, it’s stronger, smoother, and more durable than other silks. That’s why premium products like Blissy’s silk pillowcases and bedding use 100% mulberry silk for superior feel and beauty benefits.
What are the disadvantages of mulberry silk?
Main drawbacks are price and care. As a luxurious fabric, mulberry silk costs more than cotton or polyester satin. It also prefers gentle washing in cool water and no fabric softener. Still, its smooth feel, durability, and skin- and hair-friendly properties make it a worthwhile upgrade—especially with Blissy’s easy-care designs.
How is silk made without killing silkworms?
“Peace silk” (Ahimsa) lets silkworms emerge before harvesting. This humane approach yields shorter, less uniform silk fibers, so the fabric is typically less smooth and durable. Traditional mulberry silk offers the finest, most consistent results—why luxury items like Blissy’s mulberry silk pillowcase use it for a truly premium finish.
How to tell if mulberry silk is real?
Look for a soft glow, a buttery smooth feel, and “cool to the touch.” Real silk fibers also pass the burn test (hair-like smell, fine ash) while synthetic satin melts. Certifications (e.g., OEKO-TEX) and reputable brands like Blissy help ensure authentic 100% mulberry silk and a quality silk weave.
What is the difference between 100% silk and mulberry silk?
“100% silk” is a broad label; “mulberry silk” is a specific, premium fiber type. Mulberry silk comes from mulberry silkworms, producing longer, more uniform silk fibers and a consistently smoother fabric. In silk vs synthetic satin, mulberry’s natural fiber wins for comfort, breathability, and beauty benefits—ideal for pillowcases and duvet covers.
Can mulberry silk get wet?
Yes, but handle gently. Wet silk fabric is more delicate. Wash in cool water, avoid wringing, and air-dry away from direct sunlight to protect the silk weave. Blissy’s care instructions make it simple to maintain that luxurious texture across pillowcases, sleep masks, and other mulberry silk bedding.
What is the lifespan of mulberry silk?
Years with proper care. High-grade mulberry silk (e.g., 22-momme) resists wear while staying exceptionally smooth. Gentle laundering, air-drying, and storing away from heat and dust help extend longevity. Premium options like Blissy’s silk pillowcases are designed for durability without sacrificing that cloud-soft, luxurious feel.
Can you wash 100% mulberry silk?
Absolutely—just be gentle. Use cool water and a mild detergent, skip fabric softener, and air-dry flat. This protects delicate silk fibers and preserves the satin-like sheen. Blissy’s machine-washable design makes caring for luxury silk bedding surprisingly easy for everyday self care.
Why is mulberry silk so expensive?
It’s the finest, most consistent silk, and it’s labor-intensive to produce. Controlled feeding of silkworms and meticulous spinning create long, flawless threads with exceptional softness and temperature-regulating properties. The result is premium comfort and aesthetic appeal—why Blissy’s mulberry silk pillowcase is a smart investment in better hair, skin, and sleep.
