China Printing Fabric Factory introduces the processing method of seersucker:
The method of processing fibers with different shrinkage properties, such as weaving with warp yarns or weft yarns separated from polyester and cotton, and treating with sodium hydroxide solution, because cotton fibers shrink more than polyester fibers, the cloth body forms concave and convex bubbles; another example High shrinkage polyester and ordinary polyester are woven into spacer strips in the warp or weft direction, and through heat treatment, the cloth body forms concave-convex bubbles due to the different thermal shrinkage rates of the two fibers.
The raw material of seersucker is pure cotton or polyester/cotton yarn, and the density of the bubble warp is greater than that of the ground warp, or the bubble warp is made of strands, and the ground warp is made of single yarn. When weaving, the amount of let-off of the bubble warp is larger than that of the ground warp, and then dyed and finished loosely processed the cell warp to form beautiful and uneven bubbles. Using the principle that the diameter of cotton fibers increases and the length is shortened when they encounter concentrated lye.
