Every clothing manufacturer continually attempts to produce garments with immediate sales appeal. However, one of the most important materials used for nearly every item of outerwear has no sales appeal, because it is invisible to the consumer. This material is the fusible interlining, and since these materials were first introduced in the early 1950s, they have become an integral component of garment construction.
The term fusible interlining is used to describe a base fabric coated on one side with a thermoplastic adhesive resin which can be bonded to another fabric by the controlled application of heat and pressure. These materials, generally called fusible, provide the designer with a number of properties which can enhance the appearance of finished garments by the following –
a. Control and stabilization of critical areas.
b. Reinforcement of specific design features.
c. Minimum of modification to the ‘handle’ of the top cloth.
d. Preservation of a crisp and fresh look.
Correctly selected and applied, fusible have many advantages for the designer, the production unit and the consumer.
A fusible combines the following three factors in its construction –
Base material – Also called the substrate.
Thermoplastic resins – Synthetic resins which melt when subjected to heat and revert to their original solid state when cooled.
Coating – The amount of resin deposited and how it is secured on to the base fabric.
