The Research Of New Technology Of Pigment Printing Of Cashmere Fabric

For pigment printing was not restricted by fiber fabric, and it is not affected by the weaving method,combined with the advantages of digital printing dye is clear, color coherent on color vision,flowering of high precision, fast and convenient and pollution-free,this topic using digital print technology of pigment printing to pigment printingon the wool fabric.And adopted different pretreatment technology to processing in advance,including milling processing,cationic modification of pretreatment, chitosan pretreatment,rare earth pretreatment research,getting the different degrees of increase of rubbing fastness and feel level.Selection a wide variety of pigment printing binder of low temperature that are product in recent years, although sejiang, wetting penetrating agent, etc.By optimizing the best baking temperature on cashmere fabric,best glue dosage, best paste dosage, the best dosage of penetrant and to lower curing temperature to 105 ℃,solving that cashmere line brittle damage, yellowing problem, after the high-temperature baking,and printing parts have a good touch feeling, ensuring the fastness at the same time.Selection and deployment of the white ink that have the ability of cover of water-based white cover ink,optimization of the best proportion of water cover white ink and sulfur dioxide urea,in combination with the slurry and the penetrating agent,urea, antioxidant, etc giving the special black white cashmere fabric cover black(white with white at the same time) printing paste,combining the best gas steaming and baking temperature and time finally get better whiteness and handle, break the conventional giving white cover black of cashmere fabric printing technology.Screening of a variety of gold silver, gold, silver printing adhesive wetting penetrating agent and crosslinking agent of recent years production.Through optimizing the best baking temperature on cashmere fabric, gold silver powder dosage, the optimum dosage of adhesive and the best dosage of penetrant gold silver printing areas get good fastness and penetration,ensure the printing parts don’t drop powder, film is not an omission,having a shiny golden mosaic effect.
