Interlining, in the context of garment and textile production, refers to an additional layer of fabric inserted between the outer fabric and the lining of a garment. This layer is typically used to provide structure, stability, and shape to the garment. It is often found in areas that require extra support, such as collars, cuffs, lapels, and waistbands.

Here is a detailed description of interlining with a focus on its applications, types, and characteristics:

Applications

1. Garment Construction: Interlining is used to reinforce specific parts of garments like suits, coats, dresses, and jackets.
2. Home Textiles: It can be used in curtains, draperies, and other home furnishings to provide a finished look.
3. Accessories: Found in items such as hats, bags, and belts to give them a sturdier shape.

Types of Interlining

1. Fusible Interlining: Has an adhesive on one side that bonds to the fabric when heat is applied. It's easy to apply and widely used.
2. Sew-in Interlining: Requires stitching to attach to the fabric. It is used for fabrics that cannot withstand the heat of fusible interlining.
3. Non-woven Interlining: Made from fibers bonded together. It provides a stiff structure and is often used in tailored garments.
4. Woven Interlining: Made from woven fabrics, offering flexibility and durability. Suitable for lightweight and delicate fabrics.
5. Knitted Interlining: Made from knitted fabrics, providing stretch and flexibility. Ideal for knit and stretch fabrics.

Characteristics

1. Thickness: Varies depending on the required support and structure. Thicker interlining provides more rigidity.
2. Weight: Should be chosen based on the weight of the outer fabric to ensure compatibility.
3. Adhesive Properties: For fusible interlining, the quality of the adhesive determines the durability and ease of application.
4. Breathability: Important for comfort, especially in garments like jackets and coats.
5. Washability: The interlining should be compatible with the care instructions of the outer fabric.

Selection Criteria

1. Fabric Compatibility: Choose an interlining that complements the outer fabric's weight, texture, and care requirements.
2. Intended Use: Consider the specific part of the garment or item where interlining is needed and the required properties (e.g., flexibility, stiffness).
3. Durability: Ensure that the interlining will withstand the wear and care procedures of the garment
