Abstract

The invention discloses a laser heat thermal induction reduction reaction type discharge printing agent as well as a preparation method and application thereof. The laser heat thermal induction reduction reaction type discharge printing agent is composed of an active component and a catalytic component, wherein the active component comprises sodium oxalate, ammonium oxalate, glucose, sodium benzene sulfinate, sodium methanesulphinate, thiourea dioxide, citric acid, sodium citrate, ammonium citrate and de-ionized water; the catalytic component comprises hydroxyanthraquinone, zinc sulfate, a discharging-resisting fluorescent whitening agent, glycerin, polyethylene glycol and de-ionized water. According to the laser heat thermal induction reduction reaction type discharge printing agent, respective technical advantages of traditional chemical-method discharge printing and modern laser etching printing and graphic image digital control are combined together to create a new discharge printing technology which is different from the traditional chemical-method discharge printing, is also different from the present new laser etching printing, and has the characteristics of good white discharge effect, less damages on fabric fibers, less drop of fabric strength, short technical flow, convenience in operation, flexibility, energy conservation, environmental friendliness and the like.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, and more particularly relates to a laser heat-induced reduction reaction type dye discharge agent and its preparation method and application. Background technique [0002] Discharge printing technology of textiles has a long history. The traditional textile discharge printing technology is to use the printing paste prepared by chemical agents such as diaoba powder, which is printed on the fabric through a screen or a roller, and then decomposed and peeled off the dye on the fiber under high temperature steaming conditions to achieve color discharge. Although this technology can produce unique exquisite products with full background color, beautiful flower shape, but the process is cumbersome and cumbersome, the operation control is difficult, the production cost is high, and it is difficult to meet the rapidly changing market requirements of small batches and multiple varietie...
