tussenvoering

Tussenvoering, in garment construction often referred to as interlining, is a fabric layer placed between the outer fabric and the lining of a garment. Its primary purpose is to provide body and shape, improve drape, and add warmth or opacity. It also reinforces areas such as collars, lapels, and waistbands to help the garment hold its structure.

Types and materials: Interlinings can be fusible, with a heat-activated adhesive on one side that bonds to the outer fabric when pressed, or sew-in (non-fusible). They come in woven, nonwoven, or knitted forms and in different weights. Materials range from synthetic fibers (polyester, nylon) to natural fibers (cotton, wool) and blends.

Application and use: The interlining is cut to match the outer fabric and placed on the wrong side before assembly. Fusible interlinings are bonded with heat; sew-in interlinings are stitched. Interlinings are common in tailored garments such as jackets, coats, suits, collars, cuffs, and waistbands, and they can be used to add body to dresses or other structured pieces.

Care and lifecycle: Depending on the type, interlinings are durable but may lose stiffness after repeated cleaning. The choice of interlining affects the garment’s shape retention and overall longevity, and some interlinings may be replaced or refurbished when updating a piece.
