Since the left frill, the middle wrinkles and the left frill have no spandex coated yarn, the elastic band is tightened and squeezed to form wrinkles. Since the left frill and the left frill are located at the outermost edge (left and right edges) of the elastic band, there is no constraint, so a wrinkled lace is formed, which is beautiful. The wrinkles in the middle are held by the left and right plain weaves to form small wavy wrinkles, which makes the elastic band have a certain elasticity, wide and beautiful, with sufficient heat and moisture exchange space when in contact with the human body, good heat and moisture comfort, and linear contact with the human body, good contact comfort. At the same time, polyester 75D / 36f polyester Coolcon DTY warp yarn is used as functional polyester, which has antibacterial function, negative ion emission function and deodorization function.

[0053] The invention provides an elastic band with double frills and central wrinkles and a manufacturing method thereof. The elastic band is used for sewing clothing hems, clothing collars, clothing cuffs, waists, hat edges and other parts as a fastening and decorative piece, has health protection functions such as antibacterial, negative ion emission, and deodorization, has left and right frills, and is beautiful; has central wrinkles, reduces the contact area between the fabric and the human body, has a heat and moisture exchange space, and has good contact comfort and heat and moisture comfort.
