🪡 Poliflex 457 LT — Black Cotton-Blend Woven Fusible Interfacing (457)
Poliflex 457 LT is a soft, lightweight woven fusible interfacing in black, made from a cotton-polyester blend with a heat-activated adhesive backing. It irons on in seconds to add clean, lightweight body and structure without stiffening the hand or distorting the drape — the black base is ideal wherever a white interfacing would shadow through a dark fabric. Because it’s woven rather than non-woven, it moves naturally with the material instead of fighting it, making it a dependable choice for interlining, footwear, handbags, garments, and leatherwork that need gentle reinforcement in a darker shade. The soft hand keeps finished pieces flexible and easy to sew or shape.
Application couldn’t be simpler: position the interfacing adhesive-side down, press with a hot iron at 130 °C (266 °F), and it fuses in seconds — no sewing or basting required. At a 53″ width, a single roll covers a wide range of craft and production projects, making it a reliable everyday interfacing for both workshop and factory.
