    What is Momme in Silk Fabric?

    Here at Mulberry Park Silks, we are passionate about silk. All of us are true believers in the many health and beauty benefits of sleeping on silk sheets and pillowcases. We think it's a privilege to educate our clients about all things silk-related: why a silk pillowcase can be great for skin and hair; how silk bed linen can regulate body temperature; the different types of silk and what makes silk fibers special; various weaves, including charmeuse, and how they are used in bedsheets, pillowcases, and other silk products; and how to understand and interpret various silk-specific terminology, such as the universal unit of silk measurement known as "momme."

    What is Momme?

    What is Momme in Silk Fabric

    Momme [mom-ee] is a Japanese word used as a unit of weight measurement for real silk. Momme, often abbreviated as mm, is defined as the weight in pounds of a piece of fabric sized 45 inches x 100 yards. That is an incredibly long piece of fabric -- about the length of a football field! To put it terms closer to the size of sheets: one momme equates to about 4.340 grams per square meter. Eight momme fabric weighs about 1 ounce per square yard or 35 grams per square meter.

    The higher the momme, the heavier and denser the weave will be. During the process of silk production, the silk factory will adjust the density and yarn count of the silk thread to control the weight -- or momme -- of the fabric. With 30 momme charmeuse pillowcase, for example, the weft and warp of the silk fibers are woven closer together than they would be for a 19 momme charmeuse pillowcase. Higher momme silk fabrics are also made with thicker yarn. In this way, momme is similar to thread count, which is commonly used to measure the weave of cotton sheets.

    Momme ranges for different Silk Weaves

    A quick look at the typical momme (mm) range for common weaves of pure silk can further clarify the meaning:


    3 to 5 momme


    4 to 6 momme


    6 to 8 momme

    Crepe de Chine

    12 to 16 momme


    12 to 30 momme (typically used in a silk pillowcase or sheets)

    Raw silk

    35 to 40 momme (this is very heavy silk with texture)


    Anything under 20 momme is considered lightweight silk. 20 momme to 28 momme is considered midweight, with anything above 28 momme is categorized as heavy. When considering a specific weave or type of silk, higher momme is generally considered to be of better quality. Most silk sheets and bedding are made with charmeuse silk, a particular type of weave that allows extra luster and shine on the "front" of the fabric with a dull finish on the back. It is often used for items that don't require showcasing both front and back of the fabric, such as pillowcases, sheets, and duvet covers. Silk Charmeuse bedding made of 30 momme silk will be stronger, smoother, and have a richer luster than that made of 19 momme.

    The Importance of Knowing the Momme of Your Silk Sheets and Pillowcases

    Most silk bed linen -- sheets, pillowcases, and duvet covers -- are made from mid-weight silk ranging between 18 momme and 30 momme. Knowing the momme of your silk sheets can help you choose the fabric weight to suit your style, comfort, and budget.

    At Mulberry Park Silks, our silk pillowcases are made from 100% pure mulberry silk charmeuse in weights 19 momme, 22 momme, and 30 momme. The lighter weight products are made of 19 momme and include silk pillowcases, travel pillowcases, crib sheets, and toddler pillowcases, along with an extensive collection of pure silk gifts and accessories such as sleep masks, head scarves, and scrunchies. This Charmeuse silk is soft, comfortable, and affordable.

    Our silk sheets, sold individually and in sets, come in heavier weight options of 22 momme along with our duvet covers. These Charmeuse sheet sets are soft and lustrous, delivering the ultimate in comfort and a good night's sleep. With the higher momme products, the silk threads are woven more tightly, making the sheets more durable and luxurious to the touch. All our products can be machine washed (but please follow the washing instructions).

    The Advantages of Silk Fabric with Higher Momme

    As we mentioned, a 100% pure silk pillowcase or silk bed sheets with higher momme are likely to be of superior quality. As with higher thread count cotton sheets, silk bedding with higher momme will be heavier, softer, and more durable. As the table below illustrates, higher momme means MORE silk is used.

    Amount of silk used in pillowcase

    22 momme

    25 momme

    30 momme

    vs. 19 momme

    +16% more silk

    +32% more silk

    +58% more silk

    Amount of Silk Used in Pillowcase 19 Momme

    Amount of Silk Used in Pillowcase 22 Momme

    Amount of Silk Used in Pillowcase 25 Momme

    Amount of Silk Used in Pillowcase 30 Momme

    Pure silk sheets with a higher momme count should also be machine washable, which makes them easier to care for over time than a lighter weight silk fabric that may require hand washing.

    The Benefits of Silk for Hair and Skin

    It's important to note, however, that pure mulberry silk sheets and pillowcases have wonderful benefits for skin, hair, and health regardless of momme. Along with being the ultimate in luxury, silk redefines the term "beauty sleep" for hair and skin as well as overall wellness:

    • Silk tames "bed head." If you wake with a head full of tangles, it's likely due to friction from your cotton pillowcase. Silk pillowcases let your hair glide across their surface instead of snagging, no matter how much you toss and turn. You'll get a new morning look: smoother, silkier, and tangle-free. Silk also protects fragile or newly regrown hair from breakage.

    • Silk keeps hair and skin moisturized. Cotton is absorbent and pulls moisture from hair and skin while you sleep. Silk is protein-based and helps hair and skin retain precious moisture.

    • Silk minimizes "sleep wrinkles." Cotton pillowcases tug and pull at delicate facial skin, leaving it creased and wrinkled. Over time, those lines can become permanent. Silk greatly reduces that friction; minimizes the incidence of sleep wrinkles; and slows the damage they cause.

    • Silk helps regulate body temperature. When you sweat, silk wicks away moisture and keeps you cool. In cold weather, silk creates a thin insulated layer that maintains warmth. It's the ideal fabric for year-round comfort.

    • Silk is healthful. Silk is hypoallergenic and non-irritating. It's gentle on even the most sensitive or acne-prone skin. Silk is also naturally resistant to mold, dust, and mites.

    • Silk is luxurious. No fabric on earth can compare to the look, comfort, and indulgent feel of silk. Sleeping on silk is a luxury like no other.

    With that said, higher momme sheets are more densely woven, which means a greater concentration of silk thread; a richer luster; and an overall softer feel. We believe they are a worthwhile investment in your health, beauty, and sleep!
