Tips | How to distinguish whether the fabric is direct-injection digital printing or thermal transfer printing?
1. First look at the fabric. Under normal circumstances, the thermal transfer process is more suitable for polyester fabrics; if it is cotton, silk, linen, rayon and other fabrics, usually only direct digital printing can be done, if reactive digital printing is used for paper transfer The cost will be higher, so generally do not do this.
2. Ink permeability. The digital printing ink on direct-injection digital printing has good penetration and can directly penetrate into the reverse side of the fabric, so the pattern can also be clearly seen on the reverse side of the fabric; while the transferred digital printing products generally only penetrate on the front surface of the fabric, and the reverse side is almost Still the original color of the fabric.
3. There are two differences between fabrics after they are made into clothing: on the one hand, the stitches are different. If it is a paper transfer digital printing fabric, the stitches will be a little white, which is unacceptable for high-end clothing brands; on the other hand, The paper transfer digital printing fabric is dark on one side and shallow on the other, so it is not suitable for fabrics such as scarves.
4. Since the direct-injection fabric needs to be washed and finished after finishing, and the thermal transfer digital printing fabric is completed after the transfer process without any finishing, so the feel of the fabric and the floating color of the dye on the fabric also have some differences.
In general, the thermal transfer process is surface coloring, and the activity is coloring through the bottom, which is selected according to the characteristics of the fabric.
