A kind of photochromic PET film and the application in transfer printing thereof
Technical field
The present invention relates to cloth print technology field, be specifically related to a kind of photochromic PET transfer film and the application in transfer printing thereof.
Background technology
Hot transfer printing is an emerging typography.This technique mode of printing is divided into transfer film seal and transfer printing processing two large divisions, transfer film printing adopts net-point printing, pattern is imprinted on to film surface in advance, the pattern levels are rich of printing, bright in luster, ever-changing, aberration is little, repeatability is good, and the person that can reach layout requires effect, and this explained hereafter is simple, clean and tidy, convenient, requisite space is little, is applicable to very much producing in enormous quantities.
Applicant is mainly engaged in the research and development of various photochromic products, and photochromic material is opened up markets, and this kind of material has the effect of experiencing sunlight turn colors, is made into clothes or other articles for use, has visual novel sense and impulsive force.Photochromic product be printed with several different methods, hot transfer printing is a kind of mode of often taking, existing technique exists that step is complicated, repeated labor is many, the low inferior problem of production efficiency, therefore need to develop a kind of new photochromic caloric transfer printing technology, both can increase the interest of garment printing, and can increase work efficiency again.
Summary of the invention
The object of this invention is to provide a kind of easy and simple to handle, increase work efficiency, photochromic PET transfer film and the application in transfer printing thereof of good transferring effect.
For realizing above-mentioned goal of the invention, technical scheme of the present invention is as follows:
A photochromic PET transfer film, it comprises ground, prime coat, photochromic picture and text layer and hot melt adhesive layer, described ground is PET mould release membrance, if PET film is not with mould release, need be before printing, first printed mould release, then print.
Described prime coat is according to pattern demand printing, and some can bottoming, and prime coat mostly is white bottoming.
The application of described a kind of photochromic PET transfer film in transfer printing, comprises the steps:
1) bottoming on ground;
2) prepare photochromic picture and text layer: by a kind of photochromic screen printing paste printing, formed, the preparation method of described a kind of photochromic screen printing paste adopts the allotment of microencapsulation light-induced variable toner to form;
3) on photochromic picture and text layer, print hot melt adhesive layer;
4) transfer printing;
5) after printing all completes, on hot melt adhesive layer, add antitack agent and thermal fusing powder.
Described a kind of photochromic screen printing paste is a kind of in photochromic ink, photochromic water-based concentrator.
Described photochromic picture and text layer is formed by a kind of photochromic screen printing paste printing, the preparation method of described a kind of photochromic screen printing paste adopts the allotment of microencapsulation light-induced variable toner to form, and specifically in Chinese patent 201110342506.7, records.
The invention has the beneficial effects as follows: photochromic screen printing paste has adopted the processing method of microencapsulation, and suitable organic solvent and emulsifying agent have been selected, more homogeneous is good to make the effect of microencapsulation, and the color fastness to washing of the off-color material after printing and water permeability resistance etc. are improved; Variable color PET film on fabric, has shortened the time cost of printing by the direct pressing of heat pressing process greatly, has improved production efficiency.
The specific embodiment
Below principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Embodiment 1
A photochromic PET transfer film, it comprises ground, prime coat, photochromic picture and text layer and hot melt adhesive layer, described ground is PET mould release membrance, if PET film is not with mould release, need be before printing, first printed mould release, then print.
Described prime coat is according to pattern demand printing, and some can bottoming, and prime coat mostly is white bottoming.
The application of described a kind of photochromic PET transfer film in transfer printing, comprises the steps:
1) bottoming on ground;
2) prepare photochromic picture and text layer: by a kind of photochromic screen printing paste printing, formed, the preparation method of described a kind of photochromic screen printing paste adopts the allotment of microencapsulation light-induced variable toner to form;
3) on photochromic picture and text layer, print hot melt adhesive layer;
4) transfer printing;
5) after printing all completes, on hot melt adhesive layer, add antitack agent and thermal fusing powder.
A kind of photochromic screen printing paste is photochromic water-based concentrator.
The foregoing is only preferred embodiment of the present invention, be not limited to the present invention, within the spirit and principles in the present invention all, any modification of making and be equal to replacement, within all should being included in protection scope of the present invention.
