Dupioni Silk vs Raw Silk: Differences, Benefits & Price
Key Takeaways
-
Dupioni silk and raw silk both look textured and rustic, but they are not the same fabric: dupioni is a slubbed weave made when two silkworms share a cocoon, while raw silk is unprocessed silk that still carries its natural sericin protein.
-
Many shoppers buy one expecting the other, then end up with a fabric that wrinkles, scratches, or simply does not suit the project, because retailers often use the two terms interchangeably.
-
For tailored jackets, drapes, and bridal pieces, dupioni or raw silk both work well, but for anything that touches skin every night, Mayfairsilk's Grade 6A mulberry silk bedding is the right pick.
-
Dupioni runs about £15 to £27 per metre with a crisp, structured drape, raw silk sits around £17.90 per metre with a softer matte finish, and mulberry silk in 22 to 25 momme weights delivers the smoothness neither textured silk can match.
-
Mayfairsilk stocks Grade 6A mulberry silk pillowcases and bedding in 22 to 25 momme weights, made for nightly skin contact rather than the structured projects dupioni and raw silk are built for.
Dupioni vs Raw Silk: What's the Difference?
Dupioni silk is a crisp, slubbed plain weave woven from threads spun by two silkworms sharing one cocoon, and raw silk is unprocessed silk fibre that still contains sericin, the natural protein that binds the cocoon together. Dupioni runs about £15 to £27 per metre and holds its shape for tailored garments and home furnishings, while raw silk sits around £17.90 per metre with a softer, matte hand feel that suits artisanal pieces. Which one fits depends on what you are making, how much structure you need, and whether the fabric will ever touch skin.
Both silks have earned their place in bridal wear, drapery, and statement jackets, but neither was designed for the pillow you sleep on. That gap is where mulberry silk, and brands like Mayfairsilk that specialise in it, fill in.

What Is Dupioni Silk?
Dupioni silk (also spelled dupion or douppioni) is a plain weave fabric made with fine threads in the warp and uneven, thicker threads in the weft. Those uneven threads come from two silkworms that spun their cocoons together, which creates the fabric's signature slubs.
The result is noticeably thicker, crisper, and more structured than most other silks. You'll find it in bridal wear, evening gowns, jackets, and home furnishings, where its crisp body holds shape better than charmeuse or chiffon.
Benefits of Dupioni Silk
-
Structured drape: holds shape without lining in many garments.
-
Natural sheen: catches light beautifully without looking glossy.
-
Durability: the dual-thread construction resists wear.
-
Timeless look: the slubbed texture feels handcrafted and artisanal.
-
Versatility: works for both fashion and interior design.

What Is Raw Silk?
Raw silk is silk fibre or fabric that hasn't been fully processed. In its truest form, it still contains sericin, the natural protein secreted by silkworms to bind their cocoons. This protein gives raw silk a stiffer texture, a more matte finish, and a slightly rough hand feel compared to processed silks. Many artisanal and hand-woven fabrics are made from raw silk precisely because of this natural, earthy quality.
In everyday retail, the term "raw silk" is sometimes used loosely to describe dupioni or other textured silks, which is where the confusion starts. The two are technically distinct, but their shared rustic look has tangled the terms in popular usage.
Benefits of Raw Silk
-
Natural appearance: matte, unrefined texture for an understated look.
-
Eco-conscious production: small-scale, artisanal methods with minimal processing.
-
Unique hand feel: sericin gives it a texture processed silks cannot replicate.
-
Strong fibre structure: sericin adds rigidity and strength to the raw fibre.

How Much Do Dupioni Silk and Raw Silk Cost?
In the UK, plain 100% silk dupion typically costs £15–£27 per metre. Premium dupion from heritage Indian weavers or Italian mills can climb higher, especially with hand-loomed weights or embroidery.
Raw silk costs less in its unprocessed form, with pure silk fabric available at around £17.90 per metre. Dupion is durable and wrinkle-resistant, while raw silk can degrade faster if exposed to moisture before the sericin stabilises.
Key Differences Between Dupioni and Raw Silk
Place dupioni and raw silk side by side and the differences are immediately obvious. Surface texture, light reflection, weight, and drape all tell a different story. These are fundamental differences that should shape which fabric you pick for any given project, which is why professional designers treat them as separate categories even when retailers use the terms interchangeably.
Texture and Surface Appearance
Dupioni silk has a recognisable surface. Those horizontal slubs, the raised ridges running across the fabric, come from the dual-silkworm thread construction and can't be replicated artificially. The surface feels crisp and slightly rigid. Raw silk, by contrast, has a more uniformly textured surface that feels grainy or rough thanks to the retained sericin. It lacks dupioni's pronounced slubs but offers its own tactile depth.
Weight and Structure
Dupioni is noticeably heavier than most silks, and that weight gives it built-in structure ideal for garments that hold a shape, like bodices, tailored jackets, and full skirts. Raw silk in its unprocessed state is also relatively heavy due to sericin, but it becomes lighter and softer once degummed. For curtains or upholstered headboards, dupioni's weight is a real practical advantage.
Sheen and Light Reflection
Dupioni has a multi-tonal sheen that shifts as the fabric moves, often because warp and weft threads are woven in different colours (a technique called shot weaving). The iridescent effect makes it a favourite for bridal and formalwear.
Raw silk has a matte, subdued finish: the sericin coating diffuses light rather than reflecting it. It gains some lustre once degummed, but in its truest state it sits firmly on the matte end.
Breathability and Comfort
Both fabrics are natural protein fibres, so both breathe better than polyester or nylon. Dupioni's crisp, tightly woven structure sits slightly away from the skin rather than draping against it, which actually improves airflow in warm conditions. Raw silk can feel slightly rough against bare skin due to the sericin coating, though many wearers find it softens with wear and washing.
For everyday wearability, neither matches the buttery softness of high-grade mulberry silk. Dupioni works best in structured garments where skin contact is minimal, while raw silk suits looser silhouettes where breathability matters more than a smooth hand feel.

A Much More Premium Silk Option to Consider
If dupioni and raw silk represent the textured, structured end of the silk spectrum, mulberry silk sits at the opposite end: refined, impossibly smooth, and widely considered the highest quality silk in the world. Mulberry silk is produced exclusively by Bombyx mori silkworms fed on mulberry leaves, resulting in a fibre that is longer, finer, and more uniform than any other silk type. That uniformity is what gives mulberry silk its legendary softness and its bright, consistent lustre.
Unlike dupioni, which is best suited for structured garments and home furnishings, mulberry silk excels in direct skin-contact applications: pillowcases, bedding, sleepwear, and scarves. It is naturally hypoallergenic, temperature-regulating, and significantly gentler on skin and hair than cotton or synthetic alternatives. For those who love the luxury of silk but want something wearable every single day rather than reserved for special occasions, mulberry silk is in a category of its own.

Frequently Asked Questions (FAQs)
Is Dupioni Silk the Same as Raw Silk?
No, they are not the same. Dupioni is a woven fabric made from threads produced by two silkworms that spun their cocoons together, which creates its signature slubbed texture. Raw silk refers to silk fibre that hasn't been degummed, so it still contains the sericin protein that gives it a stiffer, more matte feel.
Which Is More Expensive: Dupioni or Raw Silk?
Dupioni silk typically ranges from £15–£27 per metre, while raw silk in its unprocessed form is usually less expensive. Hand-woven artisanal raw silk from regions like Varanasi or Assam can match or exceed dupioni prices, since craftsmanship drives cost more than fibre type alone. Both fabrics require dry cleaning or careful hand washing, which adds to long-term ownership costs.
Can Dupioni Silk Be Washed at Home?
Dupioni silk can be hand washed at home with care, but dry cleaning is the safer option. If you wash it at home, use cold water and a gentle silk-safe detergent, then lay the fabric flat to dry away from direct sunlight. Keep in mind that washing may slightly soften the crisp texture that defines dupioni.
What Is the Main Disadvantage of Raw Silk?
The biggest drawback of raw silk is its sensitivity to moisture and improper handling. Because of the retained sericin, the fabric can become stiff, misshapen, or damaged if it gets wet unexpectedly or is washed without care. It also lacks the smooth softness of processed silks, making it less comfortable in direct skin-contact use.
How Durable Are Mayfairsilk's Mulberry Silk Pieces?
Mayfairsilk uses 6A grade mulberry silk, the top tier of silk grading, which means the fibres are longer, more uniform, and significantly stronger than lower-grade alternatives. Higher momme weights like the 25 momme used in their bedding line also indicate a denser weave that holds up better to repeated washing. With gentle care, Mayfairsilk products are built to last for years without losing their softness or lustre.
