Problems solved by technology

The prior art mainly has the following defects: first, because metal copper is a rare metal, my country’s copper resources are relatively short, resulting in high production costs for copper products; second, the domestic production process of electroplating copper is not very mature, and electroplating technology control will exist For some defects, if you want to pursue good electroplating quality technology, you must invest a lot of money to purchase advanced equipment, so that the investment and consumption are relatively large; third, the electroplating copper roller will affect the environment, and the electroplating operation is intensive, which is not good for the health of workers. ; Fourth, the electroplating copper roller is likely to cause iron, nickel, and copper to delaminate because of poor bonding of iron, nickel, and copper after the wax is heated on the roller, resulting in quality accidents such as product printing through the bottom, waxing is not firm, etc.
Therefore, the use of copper roller engraving and printing increases the operating cost of the enterprise, and the production technology requirements are harsh and the pressure of environmental protection is high, which greatly discounts the product advantages of copper roller printing wax in the batik industry.
In addition, the current roller engraving adopts electronic engraving, the blade is easily blunted, the engraving speed is extremely fast, and some follow-up processes such as chrome plating and polishing are still required, and it is difficult to protect the original appearance of the flower shape. Therefore, it is easy to find a processing, low production cost, and environmental protection. The cleaning method has become a very important choice for batik roller printing products

Abstract

The invention discloses a method for wax printing by carving and printing of an iron roller and a method for processing the iron roller. The wax printing method is characterized by comprising the following steps of: machining to shape the iron roller by using a No.20 seamless pipe; coating waterborne photoresist GPR 501 or oily photoresist GPR 206 on the surface of the iron roller; baking the iron roller coated with the photoresist at the temperature of 60 DEG C; making a marker by using a computer to form a He-Ne laser pattern sheet; wrapping by using a film, exposing, developing, and detecting the pattern of the film; putting the iron roller wrapped with the film onto a propene polymer (PP) (plastic) corrosion machine; corroding by using a chemical corroding agent, wherein the corrosion depth of the pattern is 0.25 to 0.35mm; and installing to print wax on grey cloth, dyeing and performing post-processing. By the method, a copper roller with high cost is replaced by the iron roller, so that the cost can be greatly saved, the cost of each set of iron roller can be saved by 900RMB according to practical trial and measurement, environment friendliness is facilitated, the pollution to water, atmosphere and the like caused by electroplating the copper roller is prevented, a printed pattern has a clear outline, and registration is accurate.

Description

technical field [0001] The invention relates to a textile printing and dyeing process, in particular to a method for engraving and printing batik with an iron roller and a processing method for the iron roller. Background technique [0002] The roller wax printing technology in the batik industry occupies a pivotal position in the batik field with its printing and dyeing technical characteristics of fine printing, lively wax pattern and strong three-dimensional effect. At present, roller printing is mainly completed through the following steps: 1. Pretreatment of gray fabrics, including desizing, refining, bleaching, mercerizing, adjusting PH value, stacking, washing, etc.; 2. Electroplating copper rollers and engraving printing on copper rollers , including making electroplated copper roller cores—nickel-plated iron rollers, electroplated copper rollers, making photosensitive film, wrapping and exposure, developing, chemical corrosion, copper roller engraving inspection, et...
