Polyster fibre is the maximum synthon of output, and the printed articles of polyester piece good accounts for about 40% of terylene dyeing and printing process total amount; The major way of printed polyester has the mode such as direct printing and pigment printing:
1) direct printing: by the mill base of dispersed dye directly by the surface of screen print at polyester piece good, form coloured pattern; Then, evaporated (high-temperature steam medium) by high temperature, complete dispersed dye to the upper dye of polyster fibre and set; Again by soaping, reduction clearing, the operation such as washing, remove the dyestuff (dyestuff loose colour) and stamp medium (as thickener, additive) that above do not contaminate or do not anchor on polyster fibre, finally by oven dry or tentering setting, the printed articles of the excellent and fabrics feel soft of obtained colour fastness.Direct printing is the major way of current stamp, and the colour fastness of printed articles is excellent, printed articles soft.The maximum inferior position of direct printing is: very big to the consumption of water resources, wastewater discharge is very big, and the colourity of waste water is comparatively dark, and COD value is higher; According to statistics, produce 1 ton of fabric water consumption 200-250 ton, wherein soap, reduction clearing, the postprocessing working procedures water consumption accounting such as washing reach more than 70%.
2) pigment printing: by the mill base of coating (coloured pigments) directly by the surface of screen print at polyester piece good, form coloured pattern; Then, by high-temperature heat treatment (high-temperature hot air medium), by the effect of tackiness agent in mill base and linking agent, complete the set of coating and polyster fibre, obtained printed articles.The consumption of pigment printing to water resources is little, and wastewater discharge is little.In existing pigment printing tackiness agent and dosage of crosslinking agent larger, printing quality is bad, colour fastness is poor, the maximum inferior position of pigment printing is: the performance of tackiness agent and linking agent determines colour fastness and the feel of printed articles, for direct printing goods, colour fastness is poor, and feel is harder or coarse, and the chromatogram of coating is abundant and diversified not as good as dispersed dye.Because of the shortcoming of pigment printing, limit the application of pigment printing, small area can only be used for or to the less demanding printed articles of feel.
Along with today that requirement that is energy-saving and cost-reducing, energy-saving and emission-reduction more and more comes into one's own, the polyester piece good printing technique that necessary research and development are new.Need that both there is the advantage that stamp work flow is short, little to water resources consumption amount and wastewater discharge is little, there is again the excellent and fabrics feel soft of direct printing colour fastness, advantage that chromatogram is wide; Need to avoid the shortcoming that direct printing is large to water resources consumption amount and wastewater discharge is large simultaneously, also will avoid the shortcoming that stamp feel is harder or coarse, stamp colour fastness is poor; But existing acrylic ester emulsion polymkeric substance is mostly applicable to pigment printing, inapplicable direct printing.For this reason, need to develop the performed polymer made new advances, there is the performance that can reduce the retention rate to dispersed dye, namely improve dispersed dye to the rate of transform of fiber; Meanwhile, there is again good film-forming properties and flexibility, thus realize the short route of dispersed dye and the direct printing technology of energy-saving and emission-reduction.
