Interlining, a seemingly bland material on the surface, actually has a rich historical background. Its development began in ancient times, and it was originally used as a hand-woven fabric, and it also carried people's hopes, prayers and emotions. With the progress of social productivity, the production mode of interlining has shifted from manual to mechanized, which has brought about a substantial improvement in product quality and production capacity. In addition, the use of interlining has also ushered in diversification, from the development of clothing lining to household accessories, decorative paintings and other uses. Nowadays, interlinings are even considered as a new art medium. The future development of interlinings in what form will exist in our lives is highly anticipated.
