Silk and satin can both have a smooth, lustrous finish, so it is easy to confuse the names. The useful distinction is simple: silk tells you what a fabric is made from; satin describes how the fabric is woven.
What is a silk pillowcase?
Silk is a natural fiber. If you want a silk pillowcase, check the fiber-content label rather than relying on words such as “silky.” NIGHT’s 100% Mulberry Silk Pillowcase uses 22 momme, Grade 6A silk and has a hidden zipper.
What is a satin pillowcase?
Satin is a weave that creates a smooth face. The word alone does not identify the fiber. NIGHT’s Satin Pillowcase is made from polyester and has a traditional open-ended closure.
