What Is DTF Film Made Of
DTF film mainly consists of the following layers:
Base layer: This is the base layer of DTF film, usually made of PET (polyethylene terephthalate) film, which has good mechanical properties and stability.
Release layer: This layer prevents the coating from sticking to the PET film, ensuring that the pattern can be smoothly transferred to the fabric during the printing process.
Adhesive layer: This layer is responsible for firmly adhering the pattern to the fabric to ensure that the pattern does not fall off.
Printing layer: This is the layer where the pattern is actually printed, usually containing an ink-absorbing coating that absorbs ink and forms a clear pattern.
Protective layer: After printing is completed, this layer protects the printed pattern from damage.
Antistatic layer: Prevents the film from affecting the printing effect due to static electricity accumulation during the printing process.
The production process of DTF film includes the following steps:
Coating ink-absorbing coating: Applying ink-absorbing coating on PET film increases the clarity and adhesion of the pattern. During the coating process, attention should be paid to the control of temperature and speed to ensure that the coating is uniform and firm.
Drying and curing : After coating, drying and curing treatment is required to ensure that the coating is firmly bonded to the PET film. The drying temperature and time need to be adjusted according to the specific situation to avoid incomplete resin unsealing or reduced ink absorption capacity. Inspection and packaging : Finally, the finished product is inspected for quality and packaged to ensure that there are no defects for transportation and use.
