Silk, Mulberry Silk & Satin: What’s the Difference?

Silk is a natural fibre. Mulberry silk is a type of silk produced by silkworms that feed on mulberry leaves. Other types of genuine silk also exist, so “silk” and “mulberry silk” are related terms, but do not mean exactly the same thing.

Satin describes a weave, not a fibre. Satin can be woven from silk, polyester or other fibres. A smooth, shiny appearance does not prove that a fabric is silk: 100% polyester satin is not silk.

Check the composition, not just the headline. Words such as “silky,” “silk-like” or “satin” do not confirm silk content. Look for a clear fibre composition, and check whether it applies to the whole item or only one side.

Understand momme

Momme (mm) describes the weight of silk fabric. It is different from millimetres and from thread count.

Check the momme stated for the silk fabric on the individual listing. A higher number alone does not describe the fibre composition, stitching, closure or overall construction. Compare these details together.

Choose the right fit and finish

Measure your pillow’s width and length, then match the exact dimensions of the option you select. Standard, Queen and King names vary between countries. Convert inches to centimetres by multiplying by 2.54.

A hidden zipper encloses the pillow; an envelope closure uses an overlapping opening. Choose your preference and check the piece count. For fitted sheets, also measure mattress depth; for duvet covers, measure the duvet rather than the bed.

Care begins with the label

Always follow the care label on your item. Where hand washing is permitted, use cool water and a detergent suitable for silk. Do not use bleach, wring the fabric or expose it to high drying heat.

Machine washing is suitable only when the item’s care label permits it. Our pillowcase washing guide explains gentle washing, drying and storage. Check separate care instructions for mixed fabrics, embroidery and personalised pieces.
