Jacket nylon ink printing technology and skills

every factory engaged in jacket printing claims to have some expertise to ensure success. Most technologies revolve around improving adhesion. Some printers have made efforts to reduce the deposition of ink. China's electronic universal testing machine has also achieved a certain amount of development. They believe that this will improve the surface adhesion. Others believe that nylon must be properly "treated", including washing or impregnating the nylon surface with isopropyl alcohol or acetone, or nylon passing through a dryer before printing. These technologies are not very practical for large-scale printing business, but each has its own advantages, which should be considered

during fiber production and later jacket production, nylon can be coated with some materials, including silicone, softener and glue

use silicone to make the fiber waterproof and increase luster, but it destroys the adhesion of ink. 3. Control accuracy: upper limit +2%, lower limit ⑴% mouth growth will show a stable and progressive situation. The most common is to wipe nylon materials with isopropyl alcohol or acetone to reduce the impact of silicone. The traces of this treatment will be left on the clothes and will not disappear until the first washing or dry cleaning

the softener used on some nylon, such as taffeta, is mainly soap, which also destroys the adhesion of the ink. They form a barrier around the fiber to avoid the ink from contacting with nylon. When clothes are washed, soap dissolves in water, sometimes bringing down a part of the image in the washing solution. If nylon is obviously soft, the printer only needs to wash the jacket in advance before printing

the glue, especially the acrylic glue, decomposes when heated, and completely loses its adhesion after heat curing or Flash curing. Before printing, the jacket is preheated in a dryer to decompose the glue. In order to ensure that all residues are removed, some printing plants also pre wash after preheating

these preparations before production are time-consuming and expensive, but jackets do not need these materials to be processed, and they will be cheaper than inferior products

another way for printers to improve adhesion is to maximize the penetration of ink into textile fibers. Its purpose is to close the fiber in a way very similar to that of direct emulsion filling and surrounding the hole, so as to achieve strong mechanical adhesion. In theory, the maximum penetration of the ink, the impurities on the fiber is irrelevant, because once the ink solidifies, the impurities are fixed in place

the main variables of screen printing can be controlled to increase ink transmission. However, sedimentation should not be confused with infiltration. The purpose is to make the ink enter the fiber, not on the top of the fiber. Ink viscosity, wire mesh number and wire diameter can be changed and balanced with the slower scraper speed and larger scraper pressure of the "plastic limit order" implemented since June 2008 to achieve ideal results. But the printer must know that when using this technology, the hole should not be too large, otherwise it can't bear the image, and the ink can't be too thin, too thin will flow to the non image area. Finally, excessive penetration will damage or stain the inside of the jacket
