Spandex reactive printing process

In the reactive printing process of spandex, in the process of reactive printing of spandex, it is necessary to strictly control the temperature of the drying room, and also consider that the excessive temperature causes the vat dye to be reduced early to affect the color development.

The engraving and printing process is carried out with steaming. If it is piled up for a long time, it will cause the dye on the surface of the cloth exposed to the air to be oxidized first, resulting in permanent color difference. For the printing process of the polyester fabric with smooth surface, although there is solidity The amount of paste is relatively high, but it does not rule out the possibility that the layer is easy to be towed. The printing process can not be squeezed after falling, and the washing with spandex knitted fabric is more important than the washing of the general knitted fabric. problem.

The rope-shaped pull cylinder is the most traditional washing equipment. It is more suitable for washing knitted fabrics. However, when it comes to the engraved printing process fabric, the flat-width knitted fabric can easily puff the pulp on the fabric by spraying water. Washing off the alkali agent on the fabric and a part of the floating color and then entering the rope soaping or reducing cleaning process will get a good water washing effect.

The same weaving specifications, due to different processing methods, will produce different grams of mass, width, shrinkage and twist. The predetermined width control and temperature and speed play a decisive role.

In the processing of spandex-containing knitted fabrics, the most important thing is to grasp the problem of no wrinkles in each process, which is to start every step from weaving. The requirements for the quality, width, shrinkage and torsion of the final product containing spandex knitted fabrics must be grasped from the predetermined shape in addition to the requirements for weaving.
