What Is Lyocell? The Modern Fibre Explained

Short answer: Lyocell is a cellulose fibre just like viscose, but made in a newer and more environmentally friendly process. The solvent is gentler and is recycled in an almost closed loop. The result is a soft, strong fibre with the same comfortable properties as viscose – often with a smaller chemical footprint.

The difference between lyocell and viscose

Both fibres are made from plant cellulose, for example from bamboo or wood. The difference lies in the process: viscose uses several chemical steps, while lyocell dissolves the cellulose directly in an organic solvent that is collected and reused. We go into depth in bamboo lyocell vs. bamboo rayon.

What does lyocell feel like?

Lyocell is smooth, soft and cool to the touch, and it shares the good moisture transport of viscose. The fibre is strong at the same time, even when wet, which makes it hold up well in the wash. The properties are close to what you know from bamboo bedding and soft bamboo underwear for women.

Is lyocell more sustainable?

The process is more closed, and that is a genuine step forward. But no textile production is entirely without a footprint, and the raw material, energy and dyeing count too. Read the nuanced walkthrough in the honest guide to bamboo viscose and the environment.

Frequently asked questions

What is lyocell made of?

From cellulose from plants such as wood or bamboo, dissolved and spun into fibres in an almost closed chemical loop.

Is lyocell better than viscose?

The process is typically gentler on the environment, because the solvent is recycled. In everyday use, though, the properties are very similar to viscose.

Does lyocell shrink in the wash?

Lyocell holds its shape when it is washed gently at low temperatures. Always follow the washing instructions on the individual product.
