Problems solved by technology

[0014] However, such solutions increase rather than reduce the overall cost of the processing setup due to the large difference between atmospheric pressure and process chamber pressure; moreover, such solutions are not easily adapted to highly outgassing materials , such as, for example, fur, fabric and paper materials

Embodiment 1

[0055] Example 1: The material can be pre-exposed to a liquid, gaseous phase or gas and vapor mixture treatment, and then plasma treatment (b) can be done by using an inert gas.

Embodiment 2

[0056] Example 2: It is possible to activate the surface using a plasma process and then disperse the latter in liquid or gaseous form, or as a vapor mixture or in a colloidal state (aerosol, emulsion, sol, etc.) for active treatment ( c).

Embodiment 3

[0057] Example 3: Plasma treatment can be used to activate the target surface and increase the efficiency (a+a) of the second plasma treatment.

[0058] Further combinations of the treatments disclosed above may also be provided to obtain surface multifunctional properties.

[0059] Now, the treatment of materials such as paper, cardboard, fabric and fur materials to provide water-repellent, oil-repellent and hydrophilic properties or further improved surface properties such as anti-staining, anti-adhesion, release and anti-aging properties, as well as some examples of desired surfaces for enhanced staining, printing, resin and glue adhesion properties.

[0060] Examples of Paper Handling

[0061] Embodiment 1: (water repellency)

[0062] Different paper surfaces made of paper materials with different basis weights were processed by using the following parameters:

[0063] Corona dose: 750W.min / m 2

[0064] Pressure: 900 mbar

[0065] Carrier gas (N2): 2l n / min

Abstract

A plasma treatment method for processing a material comprises a step of subjecting the material to a substantially atmospheric-pressure plasma, thereby obviating the need of providing expensive vacuumapparatus and pumpin assemblies, while facilitating a continuous and quick treatment even in a controlled working environment. Depending on the materials to be processed, several processing methods can be used.

Description

technical field [0001] The present invention relates to atmospheric pressure plasma treatment processing methods generally used for processing materials. Background technique [0002] It is well known that techniques or methods based on plasma processing are of great importance in a large number of industrial fields, and mainly in the field of microelectronics they have become almost indispensable. [0003] Other exemplary fields in which the above-mentioned techniques or methods are advantageously used are aerospace, automotive, steel manufacturing, waste treatment and biomedical fields, where by using plasma processes, for example, it is possible to harden surfaces, change optical properties, neutralize toxic substances and improve the biocompatibility of processed materials. [0004] Surface modification of the material by subjecting the material to a plasma generally has several advantages compared to eg conventional chemical processes. [0005] In fact, the plasma pro...
