Causes and solutions for DTF printing edge warping
Recently, many friends have asked what is the reason for the warping of DTF heat transfer printing after hot pressing, and how should we correct or remedy it if it occurs? Let’s learn about it together! The warping of DTF printing is caused by the following reasons: material problems, improper hot pressing temperature, insufficient hot pressing time and equipment problems.
1. Material problem: DTF printing is hot stamping on the surface of fabric. The material of the fabric is not suitable for hot stamping. The hot stamping process will cause the fabric to deform or shrink, which will lead to edge warping.
2. Improper hot stamping temperature: When printing DTF, hot stamping temperature that is too high or too low will cause edge warping. If the temperature is too high, the fabric will be excessively deformed; if the temperature is too low, the hot stamping adhesive will not be sticky enough and cannot be firmly bonded.
3. Insufficient heat pressing time: When dtf printing is pressed, insufficient heat pressing time will cause the heat transfer glue to not completely melt and penetrate into the fabric fiber, and the heat transfer cannot be firmly fixed, causing warping.
4. Equipment problems: Equipment problems such as inaccurate temperature control, uneven pressure, or uneven ironing head of the printing machine lead to uneven heat transfer, which in turn causes warping. In order to avoid the problem of dtf warping, you can consider the applicability of the material when choosing fabrics and heat transfer designs, and ensure that the appropriate heat transfer temperature and time are used.
In addition, using reliable quality dtf printing equipment and correct operation methods can also help reduce the occurrence of warping problems. In actual operation, it is best to test a small piece of fabric first to determine the best heat transfer parameters. If warping is found after pressing, you can repeat the pressing once to achieve the effect you want
