Elasticized is a term used to describe fabrics that have been treated with an elastic material, such as rubber or spandex, to give them a STRETCHY quality. This allows the fabric to be stretched and then return to its original shape. Elasticized fabrics are often used in clothing, such as swimwear, activewear, and lingerie, as well as in upholstery and other items. The term 'STRETCHY' is often used interchangeably with 'elasticized' to describe this type of fabric.
