What is fusible interlining? Construction of fusible interlining
Introduction
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.
Definition 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,…show more content… 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.
Construction 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. The following figure shows the basic construction of a fusible and illustrates how the resin is disbursed into the top cloth when the two layers are bonded. The finished bond is referred to as a laminate.

Base materials The base materials are produced in a diversity of woven, knitted and nonwoven forms, with each type having its own particular application according to its intended function on the garment. The materials can be produced from natural or synthetic fibres or from blends of each of these fibres. Base cloths influence the following characteristics of the finished garment –
a. Handle and bulk.
b. Shape retention.
c. Shrinkage control.
d. Crease…show more content… Whilst this temperature varies according to the consumption of the top cloth, it rarely exceeds 1750 C.
Lower-limit temperature – This is the lowest temperature at which the resin starts to become viscous. For most fusible this is about 1100 C, and for the fusible used for leather and suede materials, the temperature is considerably lower.
Clean ability – The adhesive properties of the resin have to be sufficiently strong to withstand washing or dry cleaning throughout the normal life of the garment.
Handle – The resin must contribute to the required handle and non act as an unwanted stiffening agent on the final laminate.
Resin types and applications The type and properties of the most widely used resins are –
Polyethylene – At different densities this is suitable for wash and wears garments or for those which have to be dry-cleaned only.
Polyamide – All polyamide resins produce full dry-cleanable and washable bonds but there is a class of this resin which is dry-cleanable
