01 / The fiber
What’s different about Lenzing lyocell?
Lyocell is the generic name for a regenerated cellulose fiber. Lenzing is an Austrian fiber producer. It describes a closed-loop lyocell manufacturing process that recovers and reuses its solvent, and describes moisture absorption and release as a property of its branded lyocell fibers.
Fiber choice is only one part of the feel of a sheet. Yarn, weave and finishing matter too. In the LunaQ set, we pair 100% lyocell fibers sourced from Lenzing with a sateen weave for a smooth surface, soft sheen and fluid drape.
TENCEL™ is Lenzing’s fiber brand. We describe our fiber source; the submitted fabric report confirms the fiber composition, not a trademark license or the fiber’s production site.

Why fabric can feel cool at first touch.
When skin meets cooler fabric, heat moves into the fabric. Q-max measures the peak rate of that initial transfer under test conditions. LunaQ’s submitted flat-sheet sample measured 0.32 W/cm². That helps describe the first touch; it does not tell us how much cooler a person will be overnight.
Moisture handling and airflow are different properties. A bedding study by Umut Bilen compared cotton-warp fabrics with different weft blends. Some blends changed air permeability, but the study did not find a significant difference in thermal absorptivity for the blends overall. The study used different fabrics from LunaQ’s set. The useful lesson: you can’t predict cool touch from a fiber name alone.
Sleep researchers Okamoto-Mizuno and Mizuno reviewed how thermal conditions influence sleep. Warm, humid conditions can disturb sleep in the studied settings; bedding, clothing and room conditions all affect the thermal environment. This was not a test of LunaQ sheets.

A better night has a next day.
Sleep supports attention, memory and mood. The CDC emphasizes both sleep duration and quality; for adults aged 18–60 it recommends at least seven hours a day. Good sleep also means waking up feeling rested, not just meeting a number.
Start with what you can control: keep a regular sleep schedule, give yourself time to wind down, and make the bedroom quiet, relaxing and comfortably cool. Bedding is one part of the environment. It is not a treatment for a sleep disorder.
