 3. Anti-pollution (pulp) printing ⑴ resist printing: printing fabric to resist paste digital roller printing machine, and then dyed. Pre-printed on the fabric to prevent colored dyes on anti-stain color (white) pulp, which resists the dye does not affect paste dyed. Can form different parts of the printing color patterns, so-called "color proof"; if the paste does not contain dyes available white pattern, called "anti-white." Features: this printing process compared with the discharge printing process, low cost thermal transfer roller printing machine, less streaky and easy to find. The disadvantage is not as good as discharge printing pattern outline clear. Anti-pollution Principle: resists chemical and physical sub categories. Anti-chemical agent is colored dye and chemical properties of the opposite, preventing the dye or dye destruction; physical resists mostly glue or wax, clay and other substances of plants, they only play slow dyeing or mechanical stain blocking effect, does not participate in chemical reactions. ⑵ anti-paste printing fabric to make a smaller area of ??the resist printing paste supply roller printing machine, and then paste printing large surface (overprint), when the anti-pollution pulp resists semi-defense, but also less sets multi-color effect. Printing Process: paste (color paste) Preparation of Ink main components: the original original paste printing paste dye additives: 1. Original role and requirements of the original paste paste effects: (1) the dye is fixed at a predetermined position is formed partially dyed pattern (2) as a diluent dye (3) as a dye and chemical transfer agent (4) to prevent infiltration, thus enabling a clear outline of the pattern (5) the original paste steaming hygroscopic agent should have when printing performance and conditions: (1) dye, chemical stability and mechanical stirring (2) Good deformability (plasticity) (3) to a higher amount of color (4) easily washed (5) Storage stability (6) having a suitable viscosity and the ability to overcome the imbibition (7) has a certain adhesion (8) has a good film-forming sex (9) pasting easy, without pigment (10) pasting rate, cheap roller printing machine prices | rich colors all in Yu Chen (certified) | spring roller printing machine by the Dongguan City Yuchen Digital Printing Technology Co., The company offers.
