In contrast to viscose, the fibers of this fabric are not made from pure cellulose, but from cellulose acetate. Description: acetate and tri-acetate have slightly shiny surface and look rather like natural silk. They hardly crease and keep their shape well. Acetate can absorb very little moisture (only about 6 %), so it dries very quickly. However, it is very sensitive to heat (melts at about 210 degrees C) and dissolves in acetone. Tri-acetate absorbs even less moisture than acetate but is less sensitive to heat (melting point, about 300 degrees C) and can be permanently pleated. Fabric care: wash acetate by hand with normal detergent at 30 degrees or machine-wash on the delicate cycle. Dry-cleaning is also possible. Never put acetate in the drier but always hang up while still wet. It will dry quickly and hardly needs to be ironed. If it must be pressed, then do it from the wrong side under an ironing cloth and at a low temperature. Triacetate can stand normal machine-washing at 70 degrees C and a higher ironing temperature (silk/wool setting). The other care instructions are the same as for acetate.
