Heat transfer printing is mainly suitable for polyester fabrics, especially those with a high polyester content, such as sportswear and swimsuits. In addition, some blended fabrics, such as polyester-cotton blends, can also undergo heat transfer printing, but the printing effect may be affected. It is recommended to choose blended fabrics with a higher polyester content. For pure cotton fabrics, although they can also be heat transfer printed, special inks and processes are required, and the printing effect and fastness may not be as good as those of polyester fabrics.

The following is a detailed description of the fabrics suitable for heat transfer printing:

1.Polyester fabric:
Best choice: Polyester is the best medium for thermal transfer printing. Its structure is suitable for combining with transfer ink, and it can produce bright and long-lasting printed effects.
Application scope: Sports clothes, swimsuits, outdoor casual wear, banners, posters, etc.
Precautions:100% polyester fabric is the best choice. Blended fabrics can also be used to some extent, but it is recommended to choose blended fabrics with a high polyester content.

2. Polyester-cotton blended fabric:
Applicability: It can be heat transferred, but the printing effect and durability may be affected. It is recommended to choose a blended fabric with a higher polyester content.
Precautions: Ensure the fabric is properly pre-treated and select the appropriate ink and heat transfer parameters.
 

3. Pure cotton fabric:
Applicability:Theoretically, it can be heat transferred, but special ink and processes are required, and the printing effect and durability may not be as good as those of polyester fabric. Notes:
The fabric needs to undergo pre-treatment. Select ink suitable for pure cotton and adjust the appropriate temperature and pressure.
Alternative options:If you need to print on pure cotton fabric, you can consider other printing techniques such as digital direct printing.
 

4. Other fabrics:
Artificial fibers: Can be dyed, but the sublimation dyeing effect is not as good as polyester, and the color fastness is poor.
Nylon fibers: Have high strength and wear resistance, are often used in outdoor clothing, can be heat transferred, but the water wash fastness may be poor.
Spandex fibers: Have good elasticity and flexibility, are commonly used in sportswear and fitness wear, can be heat transferred.

Summary:
Heat transfer printing is mainly suitable for polyester fabrics, especially 100% polyester ones. For blended fabrics, it is recommended to choose fabrics with a high content of polyester to achieve better printing results and durability. Pure cotton fabrics can also be heat transferred, but special processes and inks are required. For blended fabrics, it is recommended to choose fabrics with a high content of polyester to achieve better printing results and durability.
