Interlining and interfacing are two types of fabric used in sewing and tailoring that serve different purposes. While both are used to provide additional structure and support to fabrics, they differ in their application, material, and usage.
Interlining refers to a middle layer of fabric that is added to a garment to provide warmth, weight, and shape retention. It is usually made of natural fabrics such as cotton, wool, or silk, and can be woven or non-woven depending on the desired effect. Interlining serves as an insulation layer between the inner and outer layers of a garment, and is used in jackets, coats, and other winter wear. It can also be used to add volume to skirts and dresses, or to make a fabric less transparent.
Interfacing, on the other hand, is a material added to a fabric to add strength, stability, and structure. It is typically made of synthetic materials such as polyester, nylon, or rayon, and is available in different weights and stiffness levels. Interfacing is used to reinforce areas of a garment that may be subject to stress and wear, such as collars, cuffs, and waistbands. It can also be used to add shape and structure to bags, hats, and other accessories.
One key difference between interlining and interfacing is their application. Interlining is usually added between the layers of a garment during construction, while interfacing is applied to specific areas of a garment before or during construction. Interlining is typically sewn in place along the edges of a fabric panel, while interfacing can be fused to the fabric using heat or sewn in place.
Another difference is the materials used. Interlining is usually made of natural fibers and is intended to add warmth and weight to a garment. Interfacing, on the other hand, is made of synthetic materials and is designed to add strength and structure to a garment.
In conclusion, while interlining and interfacing are both used to provide additional support and structure to fabrics, they differ in their application, material, and usage. Interlining is used to add warmth and weight to a garment, while interfacing is used to add strength and structure to specific areas of a garment. Understanding the differences between the two can help in selecting the appropriate material for a specific fabric project.
