Processing method of seersucker

Method of processing fibers with different shrinkage properties

For example, the warp yarn or weft yarn between polyester and cotton is woven and treated with sodium hydroxide solution. As cotton fiber shrinks more than polyester fiber, the cloth body will form bumpy bubbles; another example is the use of high shrinkage polyester and ordinary polyester in the warp. The fabric is woven into spacer strips arranged in the weft direction or in the weft direction. Through heat treatment, the fabric body forms concave-convex bubbles due to the different heat shrinkage rates of the two fibers.

The raw material of seersucker is made of pure cotton or polyester/cotton yarn, and the density of the bubble warp is higher 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 let-off volume of the bubble warp is greater than that of the ground warp, and then the cell warp is dyed and processed loosely to form beautiful, uneven bubbles. Use the principle that cotton fiber encounters concentrated lye to increase the diameter and shorten the length.
