doubleknit

Double-knit is a fabric produced by knitting two layers simultaneously, forming a single, stable material. It is typically created on a knitting machine that produces two fabric layers joined to form a double layer, with either identical or contrasting faces. The result is denser and more stable than a standard single-knit like jersey, with greater thickness and less tendency to curl.

Construction and varieties: The two layers may share stitches or be joined at the edges depending on the machine setup. The face and reverse can be identical or different in texture. A common form is interlock, a double-knit fabric in which the face and back carry the same stitch structure and present smooth surfaces on both sides. Ponte di Roma is a heavyweight double-knit used in dresses, skirts, and jackets.

Properties: Double-knit fabrics vary in weight from midweight to heavyweight. They offer good shape retention, durability, and warmth, with stretch and recovery in both directions. They are generally less prone to curling than lighter single-knit fabrics. Fiber content—such as cotton, wool, or synthetic blends—affects drape, hand, and care requirements.

Uses: Double-knit fabrics are used for tailored garments like coats, jackets, dresses, skirts, and trousers, as well as for sportswear and some upholstery applications. They are valued for structure, durability, and a smooth appearance.

Care: Care depends on fiber content. Many double-knits are machine washable, but wool and some blends may require gentle cycles or dry cleaning. When in doubt, follow the specific care label and avoid high heat to prevent shrinkage.
