Yoga wear: Coping with the

challenge of spandex dyeing and washing fastness

Yoga wear fabrics often contain 3%-20% spandex, which is highly elastic, but spandex has poor affinity for dyes and is prone to poor washing fastness. Our specially selected dye series can stably dye spandex during the dyeing stage, and can be decomposed from spandex under the action of alkali and reducing agents during the reduction cleaning process, significantly improving the fastness performance of spandex blended fabrics, which is particularly suitable for highly elastic functional clothing.
