If it is a cotton fabric with reactive dyes, the dye will react with the cotton fiber, and it is impossible to bleed with this dyeing method. Bleeding will only occur on polyester, polycotton dyed with disperse dyes, cotton dyed with pigments and other fabrics. This dyeing method is to coat the fiber surface with dye. When the fabric passes through high temperature (130~160) \u2103, the dye will sublimate and penetrate into the printed pattern, or slowly diffuse into the printed pattern over a period of time.<\/span><\/p>\n<p style=\"line-height: 1.6;\">&nbsp;<\/p>\n<h2><strong><span style=\"color: #2ab28c;\">Selection of activated carbon<\/span><\/strong><\/h2>\n<p style=\"line-height: 1.6;\"><span style=\"color: #3b3b3b;\">At present, anti-sublimation water-based inks and anti-sublimation thermosetting inks are more common in printing.

Due to the rich pore structure and huge specific surface area of activated carbon, activated carbon has the ability to adsorb gas and liquid molecules. Therefore, the pore structure of activated carbon has a very important impact on the adsorption performance of activated carbon.<\/span><\/p>\n<p style=\"line-height: 1.6;\"><span style=\"color: #5c5c5c;\">The voids in activated carbon can be divided into macropores, mesopores and micropores according to size.
