Triacetate

Semi-synthetic

Regenerated cellulose

A fully acetylated cellulose fibre with higher heat resistance and dimensional stability than standard acetate. Less common today but still used in pleat-retaining and wrinkle-resistant fabrics.

Origin & Production

Produced by fully acetylating cellulose (all three hydroxyl groups), unlike acetate which is partially acetylated. The result is a more crystalline, heat-stable fibre.

Key Properties

Excellent pleat retention
Wrinkle-resistant
Higher heat resistance than acetate
Good dimensional stability
Silk-like lustre

Common Uses

Pleated skirts & dressesFormal wearWrinkle-free garmentsBlended with other fibres

Sustainability

Derived from renewable cellulose but production uses chemicals. Less widely produced than acetate. Biodegradable. Limited recycling infrastructure.

Care Instructions

Washing

Machine wash at 30 °C on gentle cycle — triacetate handles washing better than acetate.

Drying

Tumble dry low or hang dry. More heat-resistant than acetate.

Ironing

Medium heat (150 °C). One of the few semi-synthetics that holds pleats well after ironing.

Tips

Unlike acetate, triacetate is more resistant to acetone/nail polish remover
Pleated garments can be machine washed and will retain their shape
Low-maintenance compared to other cellulosic semi-synthetics
