Silk care

Your Mayfairsilk® bed sheets will provide many years of enjoyment when you follow these simple care instructions. Due to its natural properties, you will find it requires less frequent washing than cotton bed linen:

Machine-wash in tepid water (< 30ºC / 86ºF) on delicate cycle.
Or, hand-wash in tepid water (< 30ºC / 86ºF).
Use 'delicate' pH neutral liquid detergent without enzymes.
Do not use bleach, whiteners or fabric softeners.
Do not wring or tumble dry.
Place bed sheet between two cotton towels and press gently. Most of the water will transfer into the towels. Remove, reshape and hang/line dry in the shade.
Use handheld steamer to relax creases if required (using silk attachment), or
Iron on low heat inside out whilst still slightly damp to relax creases.
You can dry clean if required (no trichloroethylene).

Traditionally, silk was made in a low momme fabric which meant it was hand-wash or dry clean only. However, MayfairSilk bed linen is crafted from high momme silk fabric using a special weave so there is more silk per inch. This makes it not only machine washable, but also provides longer durability, smoother hand-feel and deeper lustre.

So that's it. MayfairSilk is surprisingly easy to care for. Keep heat low, pH neutral detergent without enzymes, line dry in the shade. Silk is long lasting (with high momme), all natural, hypoallergenic and sustainably produced. It's truly nature's gift.

Discover for yourself why it has been regarded as the "Queen of Textiles" for over 4000 years. MayfairSilk®, where tradition meets modern design and weaving technology.

The Mayfairsilk difference

More to silk than meets the eye

Momme (pronounced ‘mom-ee’) measures the weight of silk fabric. A higher number means more silk by weight in the same area of fabric. It is one part of the picture, alongside the fibre grade, weave and finishing.

This fabric is 22 momme, Grade 6A Mulberry silk: a fluid drape, a smooth hand feel and our signature soft matte sheen. Our pillowcases use a separate 25 momme silk fabric.

What is momme? Read the full guide

22momme

The silk weight of this fabric

Weight: Momme
Fibre grade: 6A Mulberry silk
Finish: Soft matte sheen

Weight, fibre grade and finish each tell a different part of the story.

Our signature finish

A softer sheen. A modern kind of silk.

Silk needn’t have a high-gloss look. Our weave and finishing give Mayfairsilk its distinctive matte appearance, with a subtle lustre that catches the light.

Rich colour, a smooth hand feel and a relaxed, contemporary look; silk that feels as beautiful as it looks in your bedroom.
