Making method of WK160 (160-mesh WK nickel screen) rotary printing screen

Abstract

The invention provides a making method of a WK160 rotary printing screen. The method comprises making of a base die, making of the base die comprises making of a male die, the male die is in conical surface involute form, the width of a rib line on the male die is not greater than 2 micrometers, the width of the rib line on the base die after press rolling is not greater than 15 micrometers, and the making method of the WK160 rotary printing screen also comprises primary nickel plating and secondary nickel plating. According to the making method, the thickness, the aperture ratio and the pulp passing capacity of the WK160 screen are high, which are more than twice those of an existing 155-mesh rotary screen and are larger than those of a rotary screen with the mesh number being lower than 155, the thickness and the aperture ratio in the length and circumferential directions are uniform, the strength is good, and the toughness is moderate.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a printing rotary screen, in particular to a method for making a WK160 printing rotary screen. Background technique [0002] As we all know, rotary screen printing occupies a large share of the home textile printing market due to its advantages such as fast printing speed, large number of colors, simple production process, and low production cost. [0003] According to different textile fabrics, printing patterns, and printing effect requirements, there are currently 100-155 mesh printing rotary screens available in the market. The existing 155-mesh printing rotary screen has a thickness between 95 and 105 μm (micron unit symbol: μm), and an opening rate of less than 13%. Because of its high mesh density, it can print fine patterns with clear layers and better results. , suitable for printing and imitation wax printing of high-end home textile products. [0004] How...

Problems solved by technology

[0004] However, due to its small pore size, the permeable volume does not exceed 13.65 ml / mm 2 , the speed of printing should not be too fast and it is easy to block holes, which is not conducive to the penetration of slurry or wax. After printing a certain number of meters, it needs to be cleaned and used. The production efficiency is low and it is not environmentally friendly.

[0005] Moreover, the toughness of the 155-mesh mesh is soft, and it is easy to fold during plate making. The thickness of the mesh is low, the strength is poor, and the mesh is easy to break when printing. Higher cost and lower productivity

[0006] The mesh below 155 mesh has higher printing efficiency than 155 mesh in thickness, porosity, and penetration, but its mesh density is relatively small.
