Method for processing normal line of paper making felt

Abstract

The invention relates to a method for processing a normal line of a paper making felt, which is characterized by comprising the following steps of: mounting a 20-40-centimeter-wide temperature-sensitive color strip (4) printed with a brand name logo and an arrow direction in a thermal transfer stamping machine, and uniformly moving the thermal transfer stamping machine on a paper making felt (1), so that disperse dyes on the temperature-sensitive color strip (4) can be transferred onto the paper making felt (1) by means of a stamping iron plate (6) on the stamping machine, thus automatically stamping a normal line (2) color strip. The normal line of the paper making felt stamped by adopting the method provided by the invention has even and clear color, good color fastness, acid/alkali corrosion resistance and standard and stable dimensions. The invention overcomes the disadvantages of possible bending deformation and fuzziness of the normal line manufactured by felt needling and pile coating, and also avoids the defects of uneven color, poor color fastness, acid/alkali corrosion, easy color fading of the normal line and failure to calibrate the paper making felt as a result of manual spraying.

Description

technical field [0001] The invention belongs to the field of papermaking felts, in particular to a standard line processing method for papermaking felts. Background technique [0002] The papermaking felt is one of the important processes of the paper machine. It runs continuously at high speed in a closed loop on the paper machine. It is required that the relative position of the paper machine must be kept accurate during the initial installation and operation. If the initial installation position is not accurate, the felt is easy to run. Partial, gradually deformed, the water filtration performance of the blanket is reduced, and the service life of the blanket is affected. Usually people adopt the papermaking felt standard line method that is provided with ribbon on the papermaking felt to reach the relative position of papermaking felt and paper machine in operation and keep accurate in place. In the prior art, there are two processing methods for the standard thread of ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to aim at the shortcomings of the papermaking felt standard thread produced by the papermaking felt standard thread processing method in the prior art, and provide a papermaking felt standard thread processing method, so that the papermaking felt can be printed on the paper surface. The color of the thread ribbon is significantly bright, the standard thread is not deformed, the color is uniform, and it does not fade, which solves the problems of poor color fastness and corrosion resistance of the standard thread

[0005] The paper-making felt standard line printed by the paper-making felt standard line processing method of the present invention has uniform and clear color, good color fastness, acid and alkali corrosion resistance, and stable size standard; it overcomes the needling flocking in the prior art to penetrate the inside of the felt The shortcomings of the standard line produced by this method are easy to bend, deform and blur, and it also solves the problems of uneven color and poor color fastness caused by manual spraying, and when the papermaking felt is running on the paper machine due to acid and alkali corrosion and washing. Defects that the color of the thread fades quickly and cannot correct the papermaking felt
