Lyocell is a cellulose fiber, primarily made from wood pulp. The properties of Lyocell are comparable to those of viscose and silk; soft and absorbent. But Lyocell remains very strong when wet and wrinkles less.
The process to make Lyocell is more expensive, but relatively more eco-friendly, because the solvent for the wood pulp is recovered afterwards.

‘Ag’ is the symbol for silver (Argentum) in the periodic table.
Lyocell Ag+ indicates that the Lyocell fibers are fused with nano-particles of silver that actively act against odors and bacteria.
