Silk or TENCEL™ Lyocell? Look Beyond the Fabric Name

Two browser tabs are open: a silk pillowcase in one, a lyocell bedding set in the other. It is easy to compare the prices as if the products were alternatives. But perhaps the pillowcase is the only thing you meant to replace. Or perhaps the fitted sheet is worn, and a new pillowcase will leave that problem untouched. Those prices make more sense when you know what is in each parcel.

Those names on the tag

Silk is an animal-derived protein fiber. Lyocell is a regenerated cellulose fiber made from plant material such as wood pulp. TENCEL™ Lyocell is Lenzing's branded lyocell fiber. The names can sit close together in a search result, but a listing that says simply “lyocell” does not confirm Lenzing's branded fiber. The brand name has to belong to the item you are considering, not just to an article about that kind of fiber.

And even when you know the fiber, weave, construction and finishing can change how a finished item feels. A material name will not tell you how a pillowcase closes or what size a sheet is.

A pillowcase, or the whole bed?

At The Silk Space, The Absolute Silk Pillowcase is listed as 22 momme mulberry silk, with size and Single or Pair options. Our Lyocell Bedding Set is a different purchase: one fitted sheet, one duvet cover and two envelope pillowcases. The set's product page calls the fiber lyocell; it does not identify it as TENCEL™ branded. Check the selected colour and size there before ordering.

Put those two prices side by side and you are looking at different quantities, not a clean material comparison. If the pillowcase is the only piece you want to change, start there. If the fitted sheet and duvet cover are on your list too, look at the set. Either way, check the measurements and closures against what you already own. A Queen label alone does not answer every fit question.

The tag inside matters, too

The next laundry day is part of the choice. A silk pillowcase and a lyocell bedding set may look equally inviting in your browser, but they do not automatically share a wash cycle. Read the sewn-in label on each piece; then keep the silk care guide or lyocell care guide nearby for the item you choose.

When you return to those two tabs, start with the piece you wanted to replace. The material name matters, but so does what will arrive at your door.
