Seersucker Fabric is also a bumpy three-dimensional printed textile. The seersucker effect on the fabric can be obtained mainly in two ways. One method is to obtain the seersucker effect by using a mechanical method. One kind of seersucker has a single effect, which is only striped seersucker; another method is to use a chemical method to obtain the seersucker effect.
Printed seersucker textiles use chemical methods to prepare color paste containing a strong shrinkage agent or bulking agent, or water repellent agent and suitable thickener, and print it on the fabric in the form of a pattern, thereby causing the printing of the fabric. Severe shrinkage or expansion occurs at the place where there is no flower, and then the corresponding severe deformation occurs at the place without a flower, resulting in a bumpy three-dimensional flower shape on the fabric. This three-dimensional pattern effect can be infinitely varied and unrestricted. This printing textile is called seersucker printing. textile. It can be seen from the above that to obtain the printing effect of seersucker, the key is to choose an auxiliary agent that can make the fibers of the printed fabric swell or shrink violently, so that the local base fabric on the fabric undergoes physical changes to varying degrees, so as to obtain the uneven surface of the fabric. Uneven three-dimensional pattern effect.
Seekers printed textiles can be obtained in two ways, one is to print a shrinking agent on the fabric, and for cotton fabrics, a concentrated caustic soda can be printed and relaxed, so that the printed area shrinks violently, so as to obtain a three-dimensional seersucker printed fabric with an effect. Another way is: printing the water-repellent agent on the fabric, and then soaking the fabric in the shrinking agent for loose shrinkage (for cotton fabrics, it can be soaked in a concentrated caustic soda solution) so that there is a severe shrinkage at the non-flowering area. Due to the presence of water repellent in the flower area, the shrinking agent (concentrated alkali) does not work on the printing area, and the fabric does not shrink at the printing area, 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 water repellency at the printing place does not change with the dry and wet state of the fabric, while the color of the flower-free part varies with the dry and wet state of the fabric. change. Different printing methods, different auxiliaries, and different processes can produce seersucker fabrics with different effects. The pattern shape of seersucker printed fabric is not limited, and the three-dimensional effect is strong. This type of textile is widely used in various clothing fabrics.
Pure cotton fabric seersucker printing process, different fabric materials, different properties, different bulking or shrinking agents. The choice of bulking agent (shrinking agent) not only considers the good bulking effect of the fiber but also needs to consider the cost, pollution, taste, and whether it is easy to wash off in the future. For cellulose products, the most commonly used shrinking agent is caustic soda.
