What is the best ink for nylon elastic fabric?
The curing temperature of the hot melt ink is about 166 DEG C, and the optimum time of application is 8~12 h, which is enough for the printer to finish the printing task. It should be noted that once the ink is used, the unused part must be thrown away. And before the use of ink, silk screen and tools must be thoroughly cleaned.
The most commonly used nylon printing ink system is a two-component hot-melt ink and catalyst. The standard hot melt ink is similar to rubber and has good flexibility. Printed products do not exhibit flexing.
The mixing ratio of two-component hot-melt ink is generally 20 parts of hot melt ink and L catalyst. This is calculated according to mass (weight), because it is more accurate by volume than by volume. If the volume ratio must be, then the ratio of about 16:l. Ink mixing must be uniform, otherwise it will affect the curing effect of ink and the adhesion between ink and nylon fabric.
If the ink is too thick to dilute, use the thinner recommended by the ink manufacturer to ensure the quality. Diluted ink is catalysed by the fact that the catalyst will dilute the ink, so adding a catalyst to the already dilute ink will cause excessive viscosity to be used.One component inks are usually solvent based and air dried. A two-component epoxy resin or acrylic acid based ink ink can also dry air, or at 12L degrees Celsius temperature drying. The above three inks are very limited, usually less than a few hours.
