First, the computer will pattern, color separation and the design through the high precision made in Switzerland MDC electric machine, seiko carved carving the first-class quality of transfer printed version roller (gravure) use electronic DiaoKeBan roller and printing ink, will be printed on paper in special pattern, namely transfer printing paper for heat transfer printing paper after a certain time, temperature and pressure control, the pattern was printed on the cloth. Finally, using the fine print into various sewing home textile products, clothing, tourism supplies, and thousands of people went into deck beautification life!!!!!
Transfer printing and the advantages of the application:
Transfer printing with resistance to light drying, resistance to water, color fastness is strong, rich color and other characteristics, can be used for clothing, household textiles (curtain, sofa, table cloth, umbrellas, shower curtain, bags) and other products in the printing. The enterprise existing hundreds of designs and fabrics are available.
Transfer printing have a few kinds of methods:
1. The sublimation method
This is a kind of the most commonly used method, using the sublimation of disperse dyestuffs characteristics, use molecular weight for 250 ~ 400, particle diameter of 0.2 ~ 2 micron dispersal dyes and water-soluble carrier (such as sodium alginate) or alcohol-soluble carrier (such as ethyl cellulose), oil soluble resin printing ink, in 200 ~ 230 ° C on transfer printing machine processing 20 ~ 30 seconds, scatter dye move to polyester, etc synthetic fiber and a solid.
2. Move method swimming
The dye printing ink layer transfer paper according to the nature of the fiber selected. The first solid color additives fabric and paste the composition such as the mixture of padding, and then deal with under wet condition through the hot pressing, make dyes from swimming move of transfer printed paper transferred to the fabric and a solid, finally the QiZheng, washing and other wet process. The dye, fabric and transfer in transfer between paper needs to have larger pressure.
3. Melting method
Transfer printing paper with ink layer dye and wax as basic composition, through the melt pressure, will ink layer fabric embedded part ink transferred to fiber, then according to the nature of the dye makes the corresponding post-processing. Through melting method in, the need more pressure, dye shift rate with the pressure increases.
4. Ink layer stripping method
Use encounter heat to produce fiber after strong adhesion of printing ink, in smaller pressure can make whole ink printing paper transferred to the rotation of fabric, again according to the nature of the dye accordingly solid color processing.
The sublimation of transfer printed process
Will all the requirements of customers, style, color design, through the computer design fancy computer color separation-electricity carved version-the heat transfer printing gravure wheel paper-heat transfer processing to the polyester chemical fiber fabric, TC cloth, long villi fabric, artificial leather different material, the technology more than traditional printing screen printing and dyeing, printing in the design of rich fancy degree, the level of resolution, color, the bright of verisimilitude, environmental protection, and to washing, resistance to bask in and feel has greatly improved, the world speak highly and products to high-grade the popular printing and dyeing process!
The sublimation of transfer printed principle
Transfer printing is to point to the transfer of the paper will dye move to fabric printing process technology. It is according to some dispersal dyes the sublimation of the characteristics, the choice in 150 ~ 230 ° C sublimation of dispersal dyes, and with the slurry mixes "the color", again according to different design requirements, the "color" printing to transfer paper (this is a kind of special paper, therefore calls transfer paper), then the transfer of decorative pattern design with paper and fabrics, in close contact with control a certain temperature, pressure and time, dyes from printing paper transferred to the fabric, through to the diffusion into the fabric, so as to achieve the internal colouring of purpose.
The sublimation method is to use the sublimation of disperse dyestuffs characteristics, use molecular weight for 250 ~ 400, particle diameter of 0.2 ~ 2 micron dispersal dyes and water-soluble carrier (such as sodium alginate) or alcohol-soluble carrier (such as ethyl cellulose), oil soluble resin printing ink, in 200 ~ 230 ° C on transfer printing machine processing 20 ~ 30 seconds, scatter dye move to polyester, etc synthetic fiber and a solid. The sublimation of three process: general experience in transfer process all happened before, dyes were on the paper printing, printing fabric by film and air gap of the dyes to zero, the air gap concentration depends on the size of the fabric structure, yarn and the transfer of the pressure; In the process of transferring to transfer temperature, when the paper, dye sublimation, and began to volatile or in the paper and fiber is formed between volatile, when the concentration of printing fabrics to transfer temperature, in fiber surface began the dye absorption, until it reaches a certain saturated value. Because dyes from the transfer of the paper to fiber is ongoing, the absorption rate depends on the dye diffusion to the rate of fiber interior. In order to make dye diffusion, often can directional in dyed the bottom of the side that a vacuum pumping, make dye diffusion transfer to orientation; In the transfer process, dyed thing after coloring, down the content of the dyes on the paper, part of the rest of the dye migration to the paper, the internal residual dye amount depends on the vapor pressure of dyes, dyes to size or transfer the affinity of paper and printing film thickness. The sublimation law generally do not need to after wet process, can save energy and reduce the load of sewage treatment.
Transfer printing in addition to apply to synthetic fabric outside, also can be used for natural fibre pure spinning and blended fabric printing. It has the following advantages: some
(1) no water, no sewage;
(2) process short, seal is finished products, namely after don't need water, such as steaming process after;
(3) fine decorative pattern, rich administrative levels and clear, artistic quality high, stereo sense is strong, for general method cannot, and printing and printing photography and painting style of design;
(4) printing color, in sublimation process, dye residues in the transfer of tar is on paper, no pollution fabric;
(5) high, can transfer macvhine a print more precise color decorative pattern and shall not be obliged to sets;
(6) flexibility, customers can select pattern in a short period of time printed out.
