Embossed silicone printing gloves
In the global clothing industry gathering place, silicone ink is more and more widely used in the clothing printing process, similar to flat screen printing, thermal transfer flower, embossed printing, embossed printing and rope dip glue and so on. Gloves as daily life, work, sports supplies, glove manufacturers also apply silicone ink to the glove printing process, for decoration, anti-slip and trademark printing. This article describes how to use the molding process to print silicone ink on gloves.
Molding silicone ink
The main components of silicone ink are vinyl base glue, hydrogen-containing silicone, catalyst, toner, etc., the silicone ink is fully mixed and filled into the metal mold, the machine is used to close the mold, at a certain temperature (such as about 180 ° C), the curing time is 25 seconds, and the impression is printed on the glove fabric cut piece (semi-finished product).
The printing process
Single die printing process is simple, the prepared base glue and additives, color paste fully mixed into ink, due to the mixing process of air will produce some bubbles, these bubbles will make the cured silica gel to produce pores, so before the silica gel filled into the metal mold, need to place a vacuum device to extract bubbles. Of course, bubbles may also be generated when filling, and a vacuum should be pumped as much as possible to ensure that the molded silicone is more three-dimensional and tight.
The adhesion of silicone ink
Silicone ink has considerable firmness for most fabrics used in clothing, especially cotton and cotton blended fabrics, because the molecules in silicone can penetrate into the fabric, and there will be a certain degree of enrichment between molecules; Silica gel ink will greatly increase the tear strength and tensile strength after curing, which is an ideal material for clothing printing.
