Abstract
The present invention relates to a kind of method with temperature-sensitive sensitization discoloration ROTARY SCREAM PRINTING, comprise the steps: recovery and the cleaning of (1) cylinder；(2) upper photoresists: be coated with the photoresists of specific components on nickel screen after cleaning；(3) expose and imaging；(4) the described stamp that baking solidification obtains starts to occur color change or flower pattern dimly visible in 30～32 degree of regions Celsius.It is an advantage of the current invention that the exposed rear instantaneous solidification of glue being coated with on cylinder, non-light irradiation part maintains the original state, and after rinsing with water, the glue of non-light irradiation part is washed out, and light is irradiated staying of solidification and formed pattern on the net.By using the photoresists ROTARY SCREAM PRINTING of specific components, pattern is bright-coloured and flower pattern clear, and the stamp simultaneously obtained has the characteristic that temperature-sensitive is photosensitive, starts to occur color change or flower pattern dimly visible in 30～32 degree of regions Celsius.
Description
Technical field
The present invention relates to a kind of method of pattern-making on photoresist process stamp cylinder, be used primarily in dyeing.
Background technology
It is one of conventional method at dyeing cylinder stamp on the textile, needing print figure on the textile
Case is first produced on cylinder, prints on textile the most again, and what on cylinder, pattern-making was commonly used at present is Film Dosimeter, ink-jet
Method.
Dyeing is for improving production efficiency now, and major part uses ROTARY SCREAM PRINTING technique, and Photoactive Gum for Rotary Screen is that it uses
Wax spray, ink-jet and laser explosure make the required raw material during flower pattern, and printing quality is risen critical by the quality of its quality
Effect, but generally there is exposure in the Photoactive Gum for Rotary Screen produced under current technical conditions fineness is poor, time of exposure length and resistance to
The shortcoming that print rate is low, causes printing and dyeing enterprise and is difficult to be greatly improved in the flower pattern printing fine, print and dye of low grade, with
Time time of exposure and the defect of press resistance rate cause the cylinder sense that printing and dyeing cost is high, profit is low and currently marketed of printing and dyeing enterprise
Optical cement with the addition of organic solvent mostly, zest during causing the volatilization of organic solvent in lithography process and baking
The generation of smog, not only pollutes environment, and human body causes certain injury.
Summary of the invention
For drawbacks described above, it is an object of the invention to, it is provided that a kind of side with temperature-sensitive sensitization discoloration ROTARY SCREAM PRINTING
Method, uses technical solution of the present invention both to overcome the problem that pattern in ROTARY SCREAM PRINTING is the most bright-coloured and figure clarity is the highest, simultaneously
The stamp obtained has the characteristic that temperature-sensitive is photosensitive.
For achieving the above object, the technical scheme is that a kind of method with temperature-sensitive sensitization discoloration ROTARY SCREAM PRINTING,
Comprise the steps of
(1) recovery of cylinder and cleaning: chromic acid solution with 60% or the sulfuric acid solution wiping of 7%-10% for several times, eccysis net
On oil stain, then through alkali cleaning, washing, be dried；
(2) upper photoresists: being coated with photoresists on nickel screen after cleaning, wherein, photoresists comprise as follows in parts by weight

(3) expose with imaging: during exposure, the cylinder embryo having been coated with photoresists is enclosed within the cylinder air cushion of photographic machine, gas
Bag expands after inflation and makes cylinder embryo tensioning, and with black and white original text sheet tight connecting, be then exposed, time of exposure is 3-
5min, image after exposure, cylinder is placed in the tank of 30-40 DEG C immersion 5-15min. and is rinsed again, by unexposed
The photoresists eccysis at place；
(4) solidification is dried: carry out after imaging checking and repair, be dried in 50-60 DEG C of hot blast, repair with light-sensitive emulsion,
Carry out second time after repairing to expose, make the photoresists at non-decorative pattern the most photosensitive, thus improve its ruggedness, then, will circle
Net is at 160-190 DEG C of hot setting 3-5h, after cooling, is silently coating 634 epoxy resin and 650 solidifications with cylinder joining place
Agent, 60-80 DEG C of heating, makes epoxy melting set, and the described stamp obtained starts to send out in 30～32 degree of regions Celsius
Raw color change or flower pattern are dimly visible.
Preferably, described photoresists comprise following component in parts by weight:
