Satin weave is a classic weaving technique that produces fabric with a smooth, glossy front (face) and a soft, matte reverse (back). When pure mulberry silk is woven in a satin weave, the result is charmeuse silk-the luxurious fabric you know from high-end pillowcases and sheets. In this guide, we'll define satin weave in simple terms; explain how charmeuse is made; compare satin weave to other weaves; and share care tips so your silk looks beautiful for years.

Satin Weave 101: Warp, Weft, and "Floats"
In French, the word charmeuse means "charmer" - and once you touch this exquisite silk fabric, you'll understand why. Charmeuse silk, also known as silk satin, is woven using a satin weave, a technique that produces a glossy front and a soft matte reverse.
In a satin weave, the warp threads float over several weft threads-often in a "four over, one under" pattern. This arrangement exposes more of the weft on the surface, creating a luminous, reflective face and a smooth, fluid hand that defines luxury silk fabric. The reverse side, where the warp threads are more visible, has a subtle matte finish and soft texture.
All Mulberry Park Silks bedding and accessories are made from 100% pure mulberry silk woven in this elegant charmeuse satin weave. The result is a smooth, breathable, and durable silk fabric that looks as beautiful as it feels.
Before diving deeper, let's define a few important terms that help explain silk quality and construction:
Mulberry Silk: Derived from silkworms fed exclusively on mulberry leaves, this is the world's finest and most consistent silk fiber. The highest grade, 6A long strand mulberry silk, delivers exceptional softness, shine, and strength.
Satin Weave: The satin weave refers to the weaving pattern itself-characterized by long, floating warp and weft threads that give silk satin fabric its luxurious sheen. While charmeuse silk is a true satin weave, not all "satin" fabrics are made of silk; many are polyester or rayon imitations.
Charmeuse = Silk in a Satin Weave
Silk charmeuse fabric is uniquely soft with a lustrous drape, which makes it perfect for bedding. While both surfaces of the charmeuse (front and back) are soft and comfortable, the front is glossy and shiny with a beautiful luster, while the back is a duller, soft finish. This is an intentional feature of the charmeuse style of weaving. Charmeuse weave has been produced for thousands of years, first in China and later in Europe, particularly in France; this explains the Francophone origins of the term "charmeuse" which translates to "charmer." Today charmeuse silk is woven on large industrial looms similar to the one below:
Styling Note: When making a bed with charmeuse silk sheets, most people choose to lay the top sheet "front" side down, so that you are sleeping in between the smoothest surfaces. However, there is no "right" way to make your bed with charmeuse sheets; either side of charmeuse silk will confer its legendary beauty and wellness benefits (see below).
Benefits of Satin Weave Silk for Bedding
Sleeping on a charmeuse silk pillowcase or sheet set is wonderful for your hair, skin, wellness, and sleep quality .
Gentle on Hair & Skin
The soft surface of a charmeuse silk pillowcase allows your hair and face to smoothly glide across the surface. For your hair, a mulberry silk pillowcase in charmeuse weave minimizes bedhead, tangles, frizz, and knots. It also helps prevent sleep creases and facial wrinkles from forming. Regular pillowcases made of cotton fabric contain small fibers that pull and tug on hair and delicate facial skin; charmeuse silk is far gentler than cotton .
Helps Retain Moisture
Like your skin and hair, silk fiber is protein based. In fact, silk contains essential amino acids that are important ingredients found in many salon- and spa-quality hair and skin products. Mulberry silk charmeuse naturally hydrates your skin and hair while you sleep. Cotton, on the other hand, is absorbent and can actually pull moisture away from your skin and hair.
Naturally Hypoallergenic
Pure silk charmeuse is naturally hypoallergenic and resistant to mold, mites, and other irritants. This makes silk an excellent choice for anyone with sensitive skin including babies and anyone suffering from allergies, eczema, psoriasis or other irritation. Dermatologists often recommend sleeping on silk for their patients with sensitive skin. Note: While pure mulberry silk is hypoallergenic, Mulberry Park Silks has taken the extra step of having all of our silk products independently certified by OEKO-TEX as free from any harmful chemicals through every phase of production.
Temperature Regulating
The unique molecular structure of silk fiber means that charmeuse silk sheets, pillowcases, and bedding will keep you cool in the summer by wicking away moisture and warm in the winter by creating pockets of insulation. This makes charmeuse silk a versatile fabric that can keep you sleeping comfortably year-round.
Satin Weave vs. Other Weaves (Plain, Twill, Jacquard)
While charmeuse silk is the most popular type of silk weave for bedding and even clothing, there are many other styles of silk weave in the marketplace. Here are a few others you may have heard of:
- Gauze : a sheer, delicate, floaty silk
- Organza : sheer, lightweight plain weave that holds shape
- Chiffon : a plain weave sheer silk often used in evening wear and dresses
- Crepe de Chine : crisp, crinkled wave
- Jacquard : a drapey silk with a pattern woven in
- Shantung : a crisp, light silk with an irregular slub weave
- Taffeta : a crisp, plain silk weave that "rustles"
Where Momme Weight Fits In
Another important term to understand with regard to any type of silk is momme. Similar to thread count in cotton fabric, momme is the measurement of a silk's weight and the density of the weave . Higher momme count silk contains more silk fiber than lower momme count silk; it is also made with heavier silk fibers. For reference, silk gauze is typically 3 to 5 momme weight; silk chiffon is generally 6 to 8 momme weight; and silk crepe de chine ranges between 12 and 16 momme.
Mulberry Park Silks pillowcases, sheets, and bedding range from 19 to 30 momme weight, with 19 momme being roughly the equivalent of 600 thread count in cotton. Our 22 mommeweight is our most versatile and popular, with 30 momme representing the heaviest weight and most luxurious bedding we sell.
Silk Vs Satin
With the popularity of pure silk charmeuse pillowcases, bedding, and accessories, there has been a bit of confusion about the difference between silk and "satin." As we mentioned above, charmeuse is a type of satin weave. However, many unscrupulous merchants will attempt to capitalize on this ambiguity to sell an inferior silk, a silk blend, or a polyester fabric that is not at all silk to customers who think they are purchasing genuine silk.
To be clear: only pure mulberry silk charmeuse confers the health, beauty, and wellness benefits we are discussing. Furthermore, genuine natural silk is a truly luxurious fabric. Satin is a style of weaving. Satin is also a shorthand term for a smooth, charmeuse-style weave synthetic fabric that is made from petroleum-based nylon or rayon. Satin is NOT the same as silk .
So how can you tell the difference? To begin with, satin is shiny, where silk is soft and lustrous. Also, genuine silk will ALWAYS be labeled with a momme weight. You should also read the product description and the label of any item you are buying, and purchase only from a trustworthy company like Mulberry Park Silks. A reputable silk vendor will be completely transparent about the content and origins of their fabric. A very low price point is also a red flag; if a pillowcase is priced less than twenty dollars, you should be suspicious that it is not genuine silk.
Care Tips for Charmeuse (Satin Weave) Silk
Charmeuse silk bed linen from Mulberry Park Silks can be easily cared for with only a bit of extra attention. The best news: your pure silk charmeuse sheets are hand- and machine washable. We recommend using Luxury Silk, wool, and Cashmere Detergent from Heritage Park, which is specially formulated without enzymes to gently natural fibers like silk, cashmere, and wool fabric. Note: you can also use this detergent for any washable silk garment (follow the manufacturer's care guidelines).
Wash your silk items by themselves in cold water. Turn pillowcases inside out and submerge in a sink or utility tub (even a clean bathtub for sheets works well) Add a small amount of soap, submerge, and gently agitate with your hand; don't rub or scrub. Thoroughly rinse out all soap. Do not wring; if need be, roll silk in a clean, white towel to absorb excess moisture.
For machine washing, wash silk in a separate, silk-only, load. Turn silk pillowcases inside out before laundering, and place all silk items in fine mesh laundry bags to help keep the silk from tearing. This is particularly important if your machine has an agitator mechanism. Silk is a lightweight fabric that can sometimes get caught under the agitator and tear and pull. A mesh fabric wash bag will help protect your silk sheets from damage. Use cool water on a delicate or silk cycle. Again, if your silk is wet after washing, do not wring it out; use a towel to absorb excess moisture.
Never put your silk charmeuse bedding in the dryer. Hang it to dry indoors or outside away from direct sunlight, which can fade silk. You can touch up your silk with a cool iron (lowest setting, iron on the reverse) but we find that when you make your bed, the wrinkles naturally release within a day or two.
How Long Strand Silk Compares to Lower Grades
At Mulberry Park Silks, all of our products are woven from 100% pure mulberry silk made exclusively with long strand Grade 6A silk fibers-the highest grade available. We use long strand silk because it:
- Creates a smoother surface: Continuous filaments mean fewer joins or rough spots, giving our charmeuse (satin weave) fabric its signature buttery-soft feel.
- Delivers higher shine and drape: Long filaments reflect light evenly, producing that natural, luminous sheen associated with luxury silk.
- Improves strength and longevity: Fewer breaks in the yarn make the fabric more durable and resistant to pilling or tearing.
-
Enhances comfort and beauty benefits: The even surface helps hair and skin glide smoothly, reducing friction, frizz, and sleep creases.
In contrast, short strand silk (or "spun silk") is made from broken fibers-the leftovers from damaged or pierced cocoons. Those short fibers must be spun together much like cotton yarn, which produces a coarser, less lustrous, and less durable fabric. If a brand does not label their silk's grade, it is likely a lower grade.

Frequently Asked Questions About Satin Weave and Charmeuse Silk
A satin weave is a weaving technique where the warp threads float over several weft threads, creating a glossy face and a soft matte reverse. This pattern gives the fabric its signature luster, drape, and silky hand, common in charmeuse silk and silk satin.
In a plain weave, each warp thread alternates evenly with each weft thread, creating a balanced, matte fabric such as cotton or chiffon. A twill weave forms diagonal ribs, while a satin weave floats over multiple threads for a smooth, lustrous silk fabric often used in evening gowns.
Charmeuse silk is the most common type of silk woven in a satin weave. Made from long strand mulberry silk fiber, it produces an exceptionally smooth surface and natural glow—ideal for pillowcases, sheets, and accessories.
No. Satin refers to the weave, while silk describes the fiber. True silk satin is made from natural mulberry silk fibers in a satin weave, while many inexpensive “satins” use polyester or rayon. Only real silk offers the breathability, softness, and strength of genuine silk fabric.
Charmeuse silk uses a satin weave that reflects light for a radiant finish. Made from Grade 6A long strand silk fiber, this fabric is soft, durable, and naturally lustrous—perfect for bedding and evening gowns.
The satin weave exposes more weft threads on the fabric surface, giving it a smooth, fluid hand. This luxurious texture makes silk satin pillowcases feel cooler and gentler on skin than cotton or twill weaves.
Satin weave silk fabric is used for silk pillowcases, bedding, and apparel. Beyond the bedroom, silk satin is a favorite for evening gowns, blouses, and bridal wear due to its elegant drape and luminous finish.
In a satin weave, each warp thread passes over several weft threads—often four over and one under. This pattern reduces interlacing, creating the sleek, lustrous face typical of silk satin fabric, while the back appears more matte and soft.
Long strand silk fiber is continuous and unbroken, producing a tighter, smoother satin weave. The result is stronger, shinier, and longer-lasting silk fabric than short-strand or spun silk, which is often mixed with cotton.
Cotton satin (also known as sateen) uses the same satin weave but lacks the natural brilliance of silk satin. Only pure mulberry silk fibers woven in a true satin weave create the signature glow, drape, and luxurious hand of authentic charmeuse silk.
