What is fusible interlining fabric? (Comprehensive information guide)

Fusible interlining is a special type of auxiliary fabric with "glue" on the back. It's a very common material in modern garment making, making clothing production simpler and more efficient.

Here's a detailed explanation:

○ What is Fusible Interlining?

You can think of it as a **"fabric sticker"**. The front is ordinary woven or non-woven fabric, while the back is covered with tiny glue particles. This glue is dry and non-sticky at room temperature, but it melts when heated.

○ Its Main Features:

Instant Bonding: This is its biggest feature. You simply lay it on the back of the main fabric and iron it with an iron or a heat press. The heat melts the glue dots on the back, causing the interlining and the garment fabric to bond tightly together.
Provides Support: The bonded fabric becomes more structured. For example, the reason why shirt collars stand up or why suit fronts look so smooth is usually because this supportive interlining is added inside.
Prevents Fabric Distortion: Some fabrics are soft or prone to fraying. Adding this "underlining" makes the fabric much more stable, preventing it from shifting during cutting and sewing, and preventing deformation after prolonged wear.
Invisible Thickening: It's hidden inside the garment and completely invisible from the outside, but it subtly increases the thickness and feel of the fabric, making inexpensive fabrics feel more luxurious.

○ Common Types:

Woven Type: Like ordinary fabric, it has warp and weft threads, offering high strength, and is often used in high-end suits or coats.
Knitted Type: It has a certain degree of elasticity, suitable for use in garments that also have elasticity (such as sportswear), without restricting body movement.
Non-woven Type: Similar to paper in feel, it has no directional properties, is relatively inexpensive, and is often used for DIY projects or simple localized reinforcement.
