The inconvenience caused by metal thermal transfer paper warping
Thermal transfer paper uses a special thermal transfer ink to print various patterns on a special kind of paper, and then transfer the patterns to the product through temperature and pressure. This special paper in the thermal transfer process is called thermal transfer paper. Transfer printing refers to the printing process in which dyes are transferred to fabrics via transfer paper.
According to the sublimation characteristics of some disperse dyes, the disperse dyes sublimated at 150~230℃ are selected, mixed with the slurry to make "color ink", and then according to different design pattern requirements, the "color ink" is printed to Transfer paper (this is a special kind of paper, so it is called transfer paper), and then the transfer paper printed with patterns is in close contact with the fabric. Under the condition of controlling a certain temperature, pressure and time, it enters the fabric through diffusion Inside, so as to achieve the purpose of coloring.
Thermal transfer paper is a kind of coated paper. The inconsistency of the expansion and contraction rate of the coating layer and the base paper under dry and high temperature will cause single-sided warping. When the transfer paper warps, the following operations will be inconvenient:
1. The printer is inconvenient to feed paper. (Dry warping at room temperature)
2. When printing in large batches, it is inconvenient to organize due to warping. (Dry warping at room temperature)
3. Before thermal transfer, the transfer paper is warped and the alignment with the fabric is not correct, causing the transfer to fail. (Dry warping at room temperature)
4. Under the thermal transfer ironing board, the warping and rolling of the transfer paper will cause the transfer to be misaligned and cause the transfer to fail. (High temperature warpage)
The products produced by various thermal transfer paper factories at home and abroad have different degrees of warpage. The excellent quality transfer paper has a small warpage angle and slow warpage, which can meet the flatness and time requirements of the printing transfer production process. , It is easier to operate.
