How is Triacetate made?

Triacetate is a form of Acetate material. It is a synthetic fibre manufactured from cellulose and was first produced commercially in 1954.

Triacetate Manufacture

Triacetate is derived from Cellulose. The cellulose is combined with acetate from Acetic acid and Acetate Anhydride. The cellulose acetate is dissolved in a mixture of Methylene chloride and methanol for spinning.

These filaments are then put through a spinneret. Once they have emerged as long, filament fibres the solvent is evaporated in warm air. This process in known as dry spinning. The resulting fibre is almost pure cellulose acetate.

Triacetate fibres contain a higher acetate to cellulose ration than Acetate fibres. At least 92% of the Hydroxyl groups are acetylated. This is how Triacetate is recognised. It was first developed as an improved version of Acetate, improving is heat resistance among other properties.

Properties of Triacetate

  • Significantly more heat resistant than regular Acetate
  • Shrink resistant
  • Wrinkle resistant
  • Easily washable
  • Maintains creases and pleats well
  • Less absorbent than acetate

End uses of Triacetate

  • Apparel
  • Sportswear
  • Skirts
  • Materials where pleat retention is important
