Can you use Discharge Ink on Recycled TPE?

Feasibility of Discharge Ink Printing on Recycled TPE

Discharge ink printing is a popular technique used in the textile industry, particularly for creating vibrant designs on dark fabrics. However, its application on other materials such as recycled thermoplastic elastomers (TPE) is not as common. The feasibility of using discharge ink on recycled TPE largely depends on the specific properties of the TPE and the desired outcome of the print.

Is Discharge Ink Printing on Recycled TPE Advised?

While it is technically possible to use discharge ink on recycled TPE, it is not generally advised. The primary reason for this is that discharge ink is designed to work with fabrics that have been dyed, as it essentially removes the dye to reveal the natural color of the fabric. Recycled TPE, on the other hand, is not typically dyed, and therefore the discharge ink may not produce the desired effect. Furthermore, the heat required for discharge ink printing may potentially damage the TPE.

Better Printing Techniques for Recycled TPE

Given the limitations of discharge ink printing on recycled TPE, other printing techniques may be more suitable. Pad printing, for instance, is a versatile method that can be used on a variety of materials, including TPE. It involves transferring ink from a silicone pad onto the material, allowing for high-quality prints even on complex surfaces. Another option is digital printing, which can produce detailed, full-color prints on a wide range of materials. Both of these methods are more adaptable to the properties of recycled TPE and are likely to yield better results.
