Q: What does 22 momme mulberry silk mean for a pillowcase?

A: Momme (pronounced “mo-mee”) is the measure of silk’s weight and quality. A 22-momme silk pillowcase represents a premium grade — thicker, more durable, and luxuriously smooth to the touch. While many standard silk pillowcases are 19 momme, ours are made with 22 momme mulberry silk, using a tighter weave and more silk per square inch for long-lasting strength and a richer finish.

Mulberry silk refers to silk from silkworms fed exclusively on mulberry leaves — the highest-quality silk fibre available. It’s smoother, softer, and more resilient than other types. In short, 22 momme mulberry silk means your LS Silk pillowcase is exceptionally dense, ultra-smooth, and made to last.

Q: How do I wash and care for my silk pillowcase?

A: Gentle care will help preserve the beauty and feel of your silk. We recommend handwashing in cool water using a pH-neutral, silk-safe detergent. If you prefer machine washing, place your pillowcase in a mesh laundry bag and select the delicate cycle with cold water. Avoid bleach or harsh chemicals — they can damage the silk fibres and dull its natural sheen.

To dry, never wring your silk. Instead, lay it flat on a towel or hang it in the shade. Iron on a low-heat setting while slightly damp or use a steamer for best results. With proper care, your LS Silk pillowcase will remain soft, glossy, and elegant for years. (Every pillowcase comes with care instructions inside the box.)

Q: What’s the difference between a satin pillowcase and a silk pillowcase?

A: Great question — it’s one of the most common confusions. Silk is a natural fibre produced by silkworms; all LS Silk pillowcases are made from 100% pure mulberry silk. Satin, however, refers to a weave — and most satin pillowcases are made from synthetic materials like polyester.

While both may feel smooth at first, the difference is in the details. Polyester satin isn’t breathable, often traps heat, and lacks the natural softness of real silk. In contrast, mulberry silk is a breathable, temperature-regulating fibre that’s gentle on both skin and hair. It helps retain moisture, reduces friction, and is naturally hypoallergenic.

In short: silk is the real deal — natural, luxurious, and kind to you. Satin is the imitation. Always look for “100% mulberry silk” to ensure you’re getting genuine quality.

Q: How do I wash and care for my silk pillowcase?

A: We recommend gentle care to maintain the beauty of your silk. Hand-washing in cool water with a pH-neutral silk-safe detergent is ideal. If using a machine, use the delicate cycle in a mesh laundry bag. Always use cold water and avoid bleach or harsh chemicals (these can damage the silk fibers and strip its sheen). After washing, do not wring; instead, lay the pillowcase flat or hang it to dry away from direct sun. Iron on the lowest heat setting if needed (or use a steamer) while the pillowcase is slightly damp. With proper care, your LoveSilk pillowcase will stay soft and lustrous for years. (Tip: We include detailed care instructions with each pillowcase.)

Q: What’s the difference between a satin pillowcase and a silk pillowcase?

A: This is a great question because the terms can be confusing. Silk is a natural fiber produced by silkworms; our LoveSilk pillowcases are made of pure mulberry silk fabric. Satin refers to a type of weave and can be made from various materials, often polyester. In fact, many cheap “silky” pillowcases on the market are polyester satin, not real silk. While both silk and polyester satin have a smooth feel, polyester is not breathable or as gentle on skin. Silk is a breathable natural fiber – it helps regulate temperature and wicks moisture, whereas satin (polyester) can trap heat and sweat. Silk also has amino acids that are kind to hair and skin, and it’s hypoallergenic. In short, mulberry silk pillowcases offer superior comfort and benefits compared to satin imposters. Always check if “silk” products are labeled as 100% silk (like ours) to ensure you’re getting the real thing.
