The surface treatment of non-woven fabric printing should choose corona or plasma treatment
Date: Aug 04 2023 From: Star Color
The choice between corona and plasma treatment for the surface treatment of non-woven fabric printing depends on several factors, including the desired printing results, the specific characteristics of the non-woven fabric, and the available equipment and resources. Here's some information to consider:
Corona Treatment: Corona treatment involves exposing the material to a high-voltage electrical discharge, which creates a corona or plasma discharge on the surface of the non-woven fabric. This discharge modifies the surface properties of the fabric, making it more receptive to inks and coatings. Corona treatment is commonly used for improving the printability of non-porous materials.
Pros of Corona Treatment:
It is a well-established and widely used method for surface treatment.
It is relatively cost-effective and requires less complex equipment compared to plasma treatment.
It can enhance the adhesion of inks, coatings, and adhesives to the non-woven fabric.
It can be used on a wide range of non-woven fabric materials.
Cons of Corona Treatment:
It may not be as effective for certain types of non-woven fabrics, especially if they have a highly porous or textured surface.
The treatment effect may diminish over time, requiring periodic re-treatment.
It may generate ozone as a byproduct, which needs to be safely managed.
Plasma Treatment: Plasma treatment involves using low-temperature plasma to modify the surface of the non-woven fabric. Plasma is a highly ionized gas that can clean, activate, and functionalize the fabric surface. Plasma treatment is known for its effectiveness in enhancing wettability and adhesion.
Pros of Plasma Treatment:
It can provide a more uniform and controlled treatment compared to corona treatment.
It can improve the surface energy of the non-woven fabric, resulting in enhanced ink and coating adhesion.
It can effectively treat porous or textured surfaces, making it suitable for a wider range of non-woven fabrics.
It can be used to introduce specific functionalities to the fabric surface.
Cons of Plasma Treatment:
It typically requires more specialized equipment and expertise compared to corona treatment.
It may be more expensive to implement.
The treatment process may take longer than corona treatment.
The treatment effect may still diminish over time, although it is generally more long-lasting compared to corona treatment.
Ultimately, the choice between corona and plasma treatment for non-woven fabric printing depends on the specific requirements of the application, the characteristics of the fabric, and the available resources. It is advisable to consult with experts or equipment suppliers to determine the most suitable treatment method for your specific situation.
