Printed Seersucker uses chemical methods to prepare a color paste containing a strong shrinkage agent or bulking agent, or a water-repellent agent and a suitable thickener, and prints it on the fabric in the form of a pattern, thereby causing the printing of the fabric. Severe shrinkage or expansion occurs, and then the corresponding severe deformation occurs at the non-flowered part, resulting in an uneven three-dimensional flower shape on the fabric. The effect of this three-dimensional pattern can be varied and unlimited. This kind of printed textile is called seersucker printed textile. . It can be seen from the above that in order to obtain the printing effect of seersucker, the key is to choose an auxiliary agent that can cause the fibers of the printed fabric to expand or shrink violently, so that the local base fabric on the fabric will undergo physical changes to varying degrees, thereby obtaining the uneven surface of the fabric. Uneven three-dimensional pattern effect.
Seersucker printed textiles can be obtained in two ways. One way is to print a shrinking agent on the fabric. For cotton fabrics, concentrated caustic soda can be printed and relaxed to make the printing place shrink violently, so as to obtain a three-dimensional printed fabric of seersucker. Another way is: to print the water-repellent agent on the fabric, and then soak the fabric in the shrinking agent for loose shrinkage (for cotton fabrics, it can be soaked in a concentrated caustic soda solution), so that the flowerless place will shrink violently, and there will be Due to the existence of the water repellent agent, the shrinkage agent (concentrated alkali) has no effect on the printing area, and the fabric at the printing area does not shrink, thus forming another uneven three-dimensional printing effect of seersucker; the pattern on this three-dimensional printing product The pattern changes dynamically with the dry and wet state of the fabric. This is because the printing part is water-repellent, and the color of the printing part does not change with the change of the dry and wet state of the fabric, while the color of the non-flowered part varies with the dry and wet state of the fabric. change. Different printing methods, different additives, and different processes can produce seersucker fabrics with different effects. The pattern shape of the seersucker printed fabric is not limited, and the three-dimensional effect is strong. This kind of textile is widely used in various clothing fabrics.
