In addition to synthetic fabrics, transfer printing can also be used for the printing of natural fiber pure spinning and blended fabrics. It has the following advantages: Short process flow, finished product after printing, no post-processing process such as steaming and washing; simple equipment, low investment, small footprint, low energy consumption; fine pattern, rich and clear layers, artistic High, strong three-dimensional, not for the general method of printing, and can print photography and painting style patterns; printing colorful, in the sublimation process, the tar in the dye is left on the transfer paper, will not contaminate the fabric; genuine With a high rate, multiple sets of patterns can be printed at one time without the need for flowers; the flexibility is strong, and customers can print them in a shorter period of time after selecting the pattern, and can also be printed on the clothes besides the printed flower heads. Transfer printing on the finished product, such as the top of the clothing collar, cuffs, pockets on the partial printing. Transfer printing also has its disadvantages. For example, 80% of transfer printing is used for polyester fabrics, 10% for polyester blended fabrics, and 10% for acrylic, nylon, acetate fiber, etc. For natural fiber fabrics, mass production is not yet available. The scope of use is subject to certain restrictions. In addition, a large amount of paper needs to be consumed. In addition to the transfer paper, a backing paper is also required. Therefore, the area of ​​the consumed paper is twice that of the printed fabric, and the disposal of the leftover paper is also a problem. In addition, the production efficiency of transfer printing is relatively low. The output of a transfer printing machine is 3 to 4 m/min, and the high one is only about 8 m/min. It is only applicable to small batches and many varieties.
Printing ink layer peeling method
Use the ink that can produce strong adhesion to the fiber when exposed to heat, and the entire ink layer can be transferred from the transfer paper to the fabric under a relatively small pressure, and then a corresponding fixing treatment is performed according to the nature of the dye.
