This type of cotton has been treated to tighten and polish the fibers, giving it a smooth, silky feel and a natural sheen. The process makes the fabric stronger, more durable and less prone to shrinking or wrinkling, while keeping it breathable and comfortable in every season. It also absorbs dye more deeply, which means vibrant colors that last wear after wear. This unique fabric has its roots in 1844, when British chemist John Mercer discovered how a simple treatment could transform ordinary cotton into something timeless and luxurious.
