Abstract: Crepe is often used as a means of deep processing and secondary design of fabrics. The conventional crepe fabric is made on the calender for creping by the principle of thermal deformation of chemical fiber materials. The paper designed double-layer weft elastic jacquard structure, which uses the different float and shrinkage effects of the weft elastic yarn to produce the warp crinkled crepe. With a reasonable dyeing and finishing process, the fabric is formed into a warp crepe pattern, which has a threedimensional effect. After various tests on the products, the results were better than or equal to the technical specifications of conventional products.

Key words: crepe; double-layer weft elastic jacquard; structure
