4D printing includes the fourth dimension of time with the traditional 3D coordinates. Three dimensional (3D) Fabrics and textile items that can change shape and function over time are categorized as 4D Textiles. This transformation is caused by a complex interplay between hybrid materials and the exposure of external stimuli. For 4D textiles, elastic knitted fabrics and shape memory polymer are desirable materials. Medical products, soft robotics, architecture, automotive, sports, clothing and more fields may benefit from 4D textiles. In this study, the concept of 4D Textiles is reviewed in brief.
