elasticized

Elasticized describes a material that has been made elastic, either by incorporating elastic fibers into the fabric or by attaching elastic components to it. In textiles, this enables stretch and recovery, allowing garments and textile products to fit more flexibly and move with the wearer.

Elasticization is achieved through several methods. Elastic fibers such as elastane (also marketed as spandex or Lycra) can be knitted or woven into the fabric to create stretch. Alternatively, elastic tapes or cords can be sewn into edges or casing passages, producing elasticized waistbands, cuffs, hems, or trims. Another technique, shirring, uses elastic thread inserted during stitching to gather fabric and provide uniform stretch.

Materials commonly used include cotton, polyester, nylon or blends combined with elastane. The resulting fabrics vary in stretch percentage and recovery, influenced by fabric structure, stitch type, and care. Repeated stretching and washing can reduce elasticity over time.

Applications are widespread: apparel such as underwear, leggings, swimwear, activewear, and fitted garments; home textiles like elasticized fitted sheets; and some medical or support garments. The term can also describe decorative or functional edging designed to flex.

Etymology: elasticized derives from elastic, from Latin elasticus, from Greek elastikos, meaning capable of being stretched.
