Working Properties

Synthetic FOSSHAPE® can easily be cut with scissors, will not fray like conventional woven fabrics and can be readily sewn to itself or other fabrics as a hidden stiffener or shaped into stand alone structures. Fabric steamers are the often preferred method for forming a desired amount of rigidity and stiffness, but conventional steam irons or an industrial hot air gun may oftentimes be helpful. The level of stiffness is achieved by adjusting heat, time and pressure. Depending on heating technique, it will shrink in the range of 15% or more.
