2 Common Printing Methods Of Printed Seersucker

Blister fabric refers to a fabric with partial concave-convex bubbles. It is a breathable and comfortable clothing fabric such as children's shirts, blouses, pajamas, etc. It can also be used as decorative cloth for curtains, bedspreads, etc. Its processing method has two kinds of weaving method and printing method. The weaving method can only make strip seersucker, the printing method can make flower seersucker, and the pattern is not limited.

The weaving method adopts two different warp beams, ground warp, and foaming warp. The yarn count of the foaming warp is thicker, and its let-off speed is about 30% faster than that of the ground warp. Dyeing and finishing. Printed seersucker is to use chemical methods to shrink a part of the yarn on the fabric by chemical treatment, and the unshrinking yarn becomes a concave and convex bubble or is interwoven with two fibers with different shrinkage rates, one of which is treated to shrink. Shrink, another fiber becomes bump-like bubbles. There are two kinds of shrinkage treatment: physical method and chemical method. For example, high-shrinkage polyester and ordinary polyester are woven at intervals. High-shrinkage polyester is shrunk by heat treatment, and low-shrinkage polyester is curled into bubbles. For cotton and polyester spaced woven fabrics, the cotton can be shrunk by padding with cold caustic soda, while the polyester is curled into bubbles.

2 common printing methods of Printed Seersucker . One method is to print a 30%-35% NaOH solution on a single-roll printing machine with a printing roller engraved with a straight pattern and then dry it in a loose state, the cotton fiber will shrink violently, and the cotton fiber at the unprinted part will shrink. It is forced to shrink to form uneven bubbles, and then it is washed loosely and washed with caustic soda. This method can obtain strip-shaped bubbles, the width of which varies with the engraving of the fountain. The second method is to print a water-repellent agent on the cotton fabric first, and the water-repellent agent makes the printing place water-repellent. After drying, the fabric is padded with caustic soda solution and then ventilated. Where the water repellent is printed, the caustic soda solution cannot enter, and the cotton fibers in the unprinted place shrink in the lye solution, so that bubbles are formed in the unprinted place. Since the alkali-shrinked cotton fibers will continue to stretch during wearing, the bubble effect will also be weakened. Semi-finished products for printing seersucker are bleached, dyed, and printed. Printed seersuckers are mostly thin fabrics.
