After the transfer printing process began to emerge in mainland China in the 1990s, it quickly occupied the advantages of its flexible flower size and realistic printing effect, especially its almost no sewage, and its advantages in environmental protection. Many traditional direct printing techniques have market share. Through more than ten years of development, the transfer printing process has made great progress in the dark concentration, brightness, color fastness, etc. of color.
Most transfer printing uses dispersed dyes. In high temperature states, the high temperature sublimation characteristics of dispersed dyes are used to transfer them to polyester fabrics, which is called heat transfer printing. The application limitation of this process is that it can only be used. Print chemical fiber fabric. In the field of home textiles and clothing, more and more designers use natural fiber fabrics, such as cotton cloth, linen, recycled cellulose fibers, such as modal, tensil and other fabrics to achieve their design goals, giving people a natural and environmentally friendly , soft and breathable, breathable and smooth, moisture-absorbing and sweat-free. After the Danish Tansk Group’s natural fiber transfer printing process entered China, it pioneered the transfer printing on natural fibers. This transfer process uses room temperature transfer without heating during the transfer process, also known as cold transfer printing. Since cold transfer uses reactive dyes, any cellulose fiber can be colored, including cotton, linen, viscose regenerated cellulose fibers, etc. Its dye transfer rate can reach 95%, and the dye transferred to fabrics also has a fixation rate of nearly 90%. Although it also requires water washing after color fixation, it produces much less waste than traditional direct printing. Cold transfer printing is not limited by the structure of the fabric. Whether it is shuttle fabric or knitted fabric, thick fabric or thin fabric, it can be transferred. For some thicker tight fabrics, you can also use double-sided two-layer printing paper to simultaneously transfer the printing effect of double-sided printing. Since it can adopt the principle of four-color and can reflect photo effects with rich layers and infinite colors on the fabric, the exquisite printing effect can be comparable to computer printing.
The process of cold transfer printing of cotton and its printing effect can be said to be a revolution in printing and dyeing technology. It breaks the size limit of the original traditional garden screen printing, and it breaks the original traditional color number limit. The main reason is that it borrows the principle of stacking the four-color color on the original printing, which can reflect it like a photo three-dimensional layering and brightness. The effect of this printing can bring shock to all printing and dyeing professionals, and the effect of this printing is pursued by all printing and dyeing workers. This process brings the effect of printing and dyeing closer to the effect of printing, so the effect of this printing is at its peak in the printing and dyeing industry.
As the cost of the whole cotton cold transfer process further decreases, it will show its advantages in fine printing. In addition, due to the poor dimensional stability of knitted fabrics, it is more difficult to print than woven fabrics during the printing and dyeing process, and the unit price cost is high, and the whole cotton cold transfer printing will also have a great performance in the printing of cotton knitted fabrics.
