Background technology
Pigment printing be utilize some have higher tackability, macromolecular compound that suitably mechanical and physical performance and chemical property are stable at stamp after bake film forming on fabric, thereby pigment is anchored on the fabric.Pigment printing is compared with dye printing, and have following outstanding advantage: printing technology is simple, and pattern contour is clear, and the mill base colorant match is convenient, and chromatogram is complete, the color and luster favorable reproducibility; Applicability is strong, is applicable to all fibres, can also obtain the printing quality that dye printing can't or be difficult to acquisition sometimes; Low ecology load is realized energy-saving and emission-reduction.
Therefore, pigment printing has become printing method most popular in the printing in textiles, also is the main flow trend of following stamp development.If but using the thickener such as the natural hydrophilic high mol thickener of high solid content, the solid matter after the pigment printing set in the former paste can be coated by adhesive and can not eccysis, can have a strong impact on the feel of product, and is particularly outstanding when particularly printing bulk face pattern.In order to guarantee the soft feel of pigment printing product, must use the synthetic thickening agent of low solid content or the emulsion thickening of ultralow solid-containing rate.
Ultralow solid-containing rate emulsion thickening the earliest is the w/o type emulsion thickening, is water mutually in it, and the foreign minister is a kerosene, once is applied in the pigment printing of the U.S. in early days.Because the foreign minister of such emulsion thickening is a kerosene, stains equipment very easily in use and be difficult to eccysis, so promptly be eliminated very soon.Once being widely used in the A nation slurry of pigment printing in five sixties of 20th century, and belonging to O/W type emulsion thickening, is kerosene mutually in it, and the foreign minister is a water, has solved the problem of kerosene contaminated equipment.W/O or O/W type emulsion thickening all have electrolyte-resistant, anti-discharging agent, the ultralow characteristics of mill base solid content, but owing to will use kerosene, have a large amount of kerosene during oven dry and evaporate in the air, kerosene is discharged into again in the water during washing, therefore atmosphere and water source is polluted.In addition, kerosene is inflammable, causes security incident easily in the process of using.
Synthetic thickening agent has solved pollution and the safety problem that emulsion thickening exists, and transportation and store convenient, configuration is simple, clear-cut, lovely luster, is that pigment printing uses the widest thickener always.Synthetic thickening agent generally is divided into two classes: nonionic thickener and anionic thickener.
Nonionic thickener is the polyethylene glycol ether derivative mostly, though electrolyte is to not influence of nonionic thickener, its adaptability is good, but thickening effect is not as good as the anionic thickener, so large usage quantity, and prepare hydro carbons such as still needing kerosene in the printing paste process, further develop thereby limit it.And the anionic thickener is the polyelectrolyte compound, contains a large amount of ionogenic carboxyls in the molecule, is characterized in that the thickener ability is strong, and it is minimum that its viscosity is influenced by shear rate, and is little to the gloss influence.But it is to chemical addition agent sensitivities such as electrolyte, pH value, discharging agents, and bad adaptability often needs the secondary thickening in actual applications, makes former paste solid content rise.On the other hand, though its thickening capabilities is very strong, synthetic thickening agent still has certain solid content, and its pigment printing feel can't reach the soft effect of dye printing.
Therefore, for the kerosene that solves the pigment printing emulsion thickening pollutes and the electrolyte tender subject of synthetic thickening agent, need develop environmental protection, safety, good stability, solid content near zero novel emulsion system, enlarge the pigment printing The Application of Technology, improve the quality of pigment printing textiles, realize the energy-saving and emission-reduction of technology for printing fabric made simultaneously.
