Why the Word Satin Causes Confusion

The Dutch word 'satijn' refers to a glossy weave, not a fiber — a satijnen kussensloop can be made of polyester, viscose, or silk; without an explicit composition mention, there's no way to know which of the three is actually being bought.

What Only Genuine Silk Fiber Delivers, and Polyester Satin Doesn't

Polyester satin mimics the glossy look but remains a synthetic fiber that traps heat and moisture against the skin — only natural silk fiber offers the breathability and low friction documented by research.

"Satijn describes a weave, never a fiber — the only mention that guarantees silk's documented benefits is '100% zijde,' never 'satijn' alone. "
