What Momme Silk is the Best for Pillowcases? Fabric Weight Explained

Key Takeaways

• Momme is the gold standard for measuring silk quality. Higher momme means denser, more durable, and more luxurious fabric, especially important for pillowcases.

• 19 momme silk is lightweight and budget-friendly, but it may wear out faster with everyday use.

• 22 momme silk hits the sweet spot between softness, strength, and value, making it a top pick for regular use.

• 25 to 30 momme silk offers unmatched luxury and durability, ideal if you want that extra touch of long-lasting indulgence.

• Mayfairsilk crafts its 25 momme Grade 6A Mulberry silk pillowcases with care, blending elegance, sustainability, and real benefits for both hair and skin.

What is Momme?

Momme, pronounced “mommy” and shortened to mm, is how silk fabric weight and density are measured. It's based on the weight of a standard-sized silk piece, so the higher the momme, the denser and more luxurious the silk. Think of it like thread count for cotton, but more accurate for silk because silk threads are much finer, and thread count alone doesn't tell the full story.

Momme Weight Ranges and Their Typical Uses

Silks under 12 momme are super lightweight and best for delicate items like scarves. Between 12 and 16 momme, you'll find silks used in lingerie and pajamas, but they’re still too light for bedding. Once you hit 19 momme and above, you’re in the sweet spot for pillowcases and sheets, with enough density to deliver both softness and durability.

Why Momme Matters for Silk Pillowcases

Since pillowcases face daily friction and washing, momme plays a big role in how long they last and how they feel. Higher momme silk is tougher, more resistant to wear, and has a richer texture with a deeper shine. While all silk offers natural benefits like being gentle and moisture-wicking, heavier silk can hold up better over time, keeping those perks intact longer.

Additional Factors Influencing Silk Pillowcase Quality

• Manufacturing Quality: Don’t underestimate the finishing touches! Well-executed stitching, thoughtful dyeing, and crisp seams all add up to a pillowcase that looks, feels, and lasts better.

Frequently Asked Questions (FAQ)

How long does a 22 momme silk pillowcase typically last?

With good care, a 22 momme silk pillowcase can last 1–2 years of nightly use. That’s about 100–150 gentle washes before wear and tear starts to show.

Can I machine wash higher momme silk pillowcases?

You can, as long as you do it carefully. Use a mesh laundry bag, a delicate cycle with cold water, and a detergent made for silk. Avoid heat, fabric softeners, and bleach, and always air dry out of direct sunlight. Heavier momme silk holds up better than lighter weights, but it still needs good maintenance.

Why are 19-momme silk pillowcases so much cheaper?

They use less silk, around 14% less than 22 momme and nearly 37% less than 30 momme, so they cost less to produce. That makes them a more budget-friendly entry point into silk, but with trade-offs in durability.

Will a higher momme silk pillowcase help with my hair and skin more?

Yes, but only slightly. All silk pillowcases reduce friction and retain moisture, which is great for hair and skin. Heavier momme silk has a denser weave that stays smoother longer, giving a small boost in those benefits. But the biggest difference is when you switch from cotton to silk; going from 22 to 30 momme is more of a luxury upgrade than a must for most people.

Are Mayfairsilk pillowcases suitable for sensitive skin and allergies?

Absolutely! They're naturally hypoallergenic, antibacterial, and dust mite resistant, making them a gentle and safe choice for sensitive skin and allergy-prone sleepers. Check out our collection today!
