Resins

These are the materials applied to the base cloth and when subjected to heat and pressure, they become the sole bonding agent between the top cloth and the interlining. Thermo plasticity, or change with heat, is the basis of all fusible interlinings; in its cold state the resin is not adhesive and only becomes viscous when heated. Through the application of pressure the heated resin penetrates into the top cloth; on cooling, it solidifies again, so forming a bond between the two fabrics.

Today no naturally occurring resins are used for interlinings, but a large variety of thermoplastic resins are used including polyamides, polyester, PVC, etc.
