Lightweight, nonwoven white iron on fusible interfacing. 100% polyester, 20 wide. Backed by a dry adhesive film that is activated by heat, HeatnBond interfacing forms a nose bond three times stronger than other traditional fusible web without adding weight or stiffness. With a low temperature and short pressing time, it allows for a wider range of materials to be bonded. There is no seam or pressing cloth needed, and it will not lift or pucker after washing. Machine washable, dry cleanable.
