Printed Seersucker is a printing method that uses the principle that the diameter of the fiber increases and the length shortens when it encounters a bulking agent, causing different physical changes in the fabric part and the base fabric, and forming uneven patterns on the surface of the fabric. Its product is called seersucker. There are bubbles on the surface of the fabric, which makes it not close to the body and has a cool feeling when worn. It is suitable for children's clothing, shirts, dresses, pajamas, etc.; the seersucker with thicker yarns can be used to make bedspreads, curtains, etc.
According to the different principles of bubble formation, seersucker is divided into weaving seersucker and alkali shrinkage seersucker; according to different printing and dyeing processing methods, it is divided into dyed seersucker, printed seersucker, and yarn-dyed seersucker. Most of the woven seersuckers are yarn-dyed color strip products, some are cotton, and some are pure fiber or chemical fiber blends, and it is troublesome to change the variety. Alkali-shrunk seersucker is produced by foaming printing process, so its pattern layout is limited to grids, with rich varieties of designs and colors, and the raw materials are all cotton or synthetic fibers; compared with weaving seersucker, the process is simple, and printing and foaming can be completed at one time, and can be carried out alternately with printing processing, which can produce various effects.
Foaming printing process: There are basically two processes in foaming printing: one is to use the principle that cotton fiber expands when it encounters concentrated alkali, its diameter increases, and its length shortens, and caustic soda paste alkali is directly printed on cotton fabrics. The fiber shrinks, and the non-pattern area foams, and the resulting seersucker is called alkali seersucker; the other is to print alkali-resistant pulp on the cotton fabric, and then pad the lye, then the non-pattern area shrinks, and the pattern area foams, Acquired colorful bubble pattern.
