What regenerated fabrics are and how they differ from virgin fibers

Short answer: regenerated fabrics are made from fibers obtained from natural raw material, usually wood cellulose, which goes through a chemical process to become yarn. Viscose, modal and lyocell are examples. They differ from virgin natural fibers, like cotton and linen, which are only harvested and spun, and from synthetic ones, like polyester, made from petroleum.

A simple classification

1. Natural fibers: come from plants or animals and are processed mechanically, like cotton, linen, wool and silk.
2. Synthetic fibers: are produced chemically from petroleum derivatives, like polyester, nylon and elastane.
3. Regenerated or man-made cellulosic fibers: start from a natural material, like cellulose, that is dissolved and turned into yarn.

Common examples

• Viscose: soft and fluid, good for dresses and blouses. It tends to shrink and lose shape with improper washing.
• Modal: a variation of viscose, usually stronger and softer to the touch.
• Lyocell: produced in a process that aims to recover much of the solvent, and is therefore often presented as a lower-impact alternative, although the result depends on the manufacturer.
• Acetate: derived from cellulose, with a silky feel, common in linings.

What matters for impact

Impact depends on the origin of the raw material, forest management, the chemicals used and how effluents and waste are treated. Labels and certifications can help verify practices, but it is worth checking who issues the label and what it covers. Labels that merely say "natural" or "eco" are not enough.

What to look at on the label

• The composition by percentage.
• The washing instructions, since regenerated fibers often need more care.
• The presence of blends with synthetic fibers, which change feel and durability.

Counterpoints

Regenerated does not automatically mean sustainable, nor does synthetic always mean worse. Performance and impact depend on the whole: fiber, process, durability and use.
