What is the fiber composition of Fusible Interlacing?

• A. 70% Cotton, 30% Polyester
• B. 80% Polyester, 20% Nylon
• C. 100% Polyester
• D. 60% Polyester, 40% Nylon

Answer: (B)

Fusible interlining needs a fiber mix that fuses well to fabric while still providing stability and a comfortable hand. A high portion of polyester gives the heat-seal and dimensional stability that create a firm, durable bond. Adding nylon brings a bit of elasticity and tear strength, helping the interfacing resist stiffness and maintain shape after washing. The blend of eighty percent polyester and twenty percent nylon strikes a practical balance between easy fusing, durability, and a softer hand, which is why this composition is commonly used. Other mixes, such as those with cotton or higher nylon content, don’t fuse as consistently or can alter hand and performance in less desirable ways.
