Rayon acetate is a blend of man-made material (acetate) and natural fibre (rayon). The blending of these materials creates a fabric that is delicate and yet stronger than acetate alone. You can iron rayon acetate, but you must take precautions you would not need to take with fabrics such as cotton. Rayon acetate can burn more easily than heavier fabrics.
Place a thin, clean white cloth or pillow case on your ironing board. Even if your board looks clean, it may not be and the dirt can transfer to the fabric.
Turn the fabric inside out, if it is a garment. For best results, you should iron the less shiny side of the material; this is an additional precaution against damaging the appearance of the fabric.
Turn on your iron to the lowest setting. Rayon acetate can be damaged by heat--do not use a hot iron on this fabric.
Spread the fabric evenly and loosely--do not stretch it--over the ironing board. Fill a clean spray bottle with water. Mist the fabric lightly to dampen it.
Place a thin, white cloth (use T-shirt material or pillow case material if you do not have a press cloth) over the material. This offers additional protection from heat and from direct contact with the iron; substances on the iron can be transferred to the material. Also, some irons have areas that heat up more than other areas and may burn the fabric.
Iron small areas at a time. Try not to stretch the fabric as you do so, and avoid leaving the iron pressed against one area for long. Keep the iron moving as you iron and press only lightly.
If the iron starts to get too hot, unplug it and let it cool before resuming ironing.
