What is transfer printing? Transfer printing is to print pigments or dyes on paper, rubber or other carriers, and then transfer them to the fabric to be printed. Now most of the transfer printing is applied to polyester fabrics, and it is less applied to other fabrics. How to apply this technology to other fabrics will be the future development direction of transfer printing. Let's first introduce the technical methods of transfer printing we have now.
The current transfer printing is generally divided into wet method, dry method, steam method, vacuum method, thermal method and other forms. The advantage of transfer printing is that because it can accurately reproduce the pattern, it is possible to apply mechanized production to reality, and its production method is simpler. In terms of post-printing processing, it is more than the traditional printing and dyeing process. Convenient, so many factories began to use transfer printing methods to replace traditional printing and dyeing. However, in our country, the factories that use traditional printing and dyeing still account for the majority.
At present, the most widely used in transfer printing is hot-melt resin except polyester, in addition to polyamide, vinyl acetate copolymer and polyurethane. In addition to polyester, transfer printing has also made a certain breakthrough in nylon fabrics. Polyamide hot-melt adhesives have strong adhesion, toughness, low temperature resistance, and good affinity with nylon fabrics, so they are suitable for preparing nylon transfer printing paper. Ethylene-vinyl acetate copolymer has a low melting point and strong adhesion. It is suitable for producing transfer printing paper after adding printing ink.
How to use the characteristics of transfer printing to make it appear on fabrics other than polyester is the difficulty of contemporary printing and dyeing technology. We can first analyze the characteristics of transfer printing.
1. The transfer printing pattern has the characteristics of lifelike pattern, detailed pattern, clear level and strong three-dimensional effect. Transfer printing can print natural scenery and artistic patterns.
2. The transfer printing equipment has the characteristics of simple structure, small area, low investment and high economic efficiency. And its printing and dyeing is suitable for all kinds of fabrics with inconsistent thickness. It is also extremely convenient in the processing after printing, and it can be directly produced without too much post-processing.
3. Transfer printing is very environmentally friendly compared to traditional printing in terms of environmental pollution. Because it is a dry process, there is no need for washing, steaming, drying and other processes, so no waste gas and waste water are discharged.
4. Transfer printing has the advantages of high production efficiency, labor saving and easy operation. The production efficiency of transfer printing is extremely high, it can save a lot of labor, and the operation is simpler than the complicated and complicated of traditional printing.
