Evelon is a soft handle, non-woven synthetic. Drapes like soft fabric with the appearance of suede - hence, 'SuedeFX'.
The direct application of heat from a heat gun causes SuedFX to create distorted bubbles and holes - a combination of some of the characteristics of Tyvek Film and FibreDK. It also becomes hard (losing the drape) with this heat application creating rigid 3D effects.
SuedFX can be ironed without distortion so enabling the use of Transfer Dyes and Transfer Paints. When printed in this way the colours are strong.
