Elastane in Clothing

Stretch can come from an elastic fiber, a knitted structure, or a flexible material with a different chemistry. Elastane, spandex, and Lycra terminology should be distinguished from fabric names such as jersey. Checking the composition alongside the textile construction explains more than assuming that every stretchy garment contains the same ingredient.

A fabric made with loops

Jersey is a knitted fabric rather than a single raw material. The source describes earlier wool versions and the widespread modern use of cotton and synthetic fibers. Its close-knit structure, stretch, and ability to drape make it familiar in T-shirts, underwear, and other garments worn close to the body.

Elastane in Clothing: Jersey Is a Knit Structure Used Across Many Fibers

Look beyond the garment name

An athletic jersey is a type of clothing, whereas jersey fabric is a textile construction; the two terms should not automatically be treated as identical. Fiber content also changes how a jersey knit feels and hangs. Comparing fabrics therefore means checking both the material and the knit, especially when a similar-looking garment uses a different blend or has a different intended role.
