How does atmospheric pressure plasma cleaning machine improve the hydrophilicity of non-woven fabrics!

Plasma cleaning is a process that uses plasma technology to modify and clean the surface of non-woven fabrics. It mainly involves physical or chemical reactions between high-energy particles (such as ions, electrons, free radicals, etc.) and molecules on the surface of non-woven fabrics to achieve the effects of cleaning, activation, etching, or coating deposition.

High energy particles in low-temperature plasma can bombard the surface of fiber textiles, effectively removing residual organic pollutants and small particle impurities on the product surface, and achieving a highly clean state on the surface. Through the physical sputtering effect of plasma (such as argon plasma), the surface of non-woven fibers can be etched at the nanoscale, increasing surface roughness and specific surface area.

PET dust-free cloth is commonly used to clean sensitive surfaces such as LCD, PCB, camera lenses, etc. 

Therefore, a soft material with good hydrophilicity and cleaning efficiency is required. The wettability and hydrophilicity of PET dust-free cloth itself cannot meet the requirements of good hydrophilicity, which will affect the use of PET dust-free cloth. If we want to solve the problem of poor hydrophilicity of PET dust-free cloth, we first need to understand the reasons. As mentioned earlier, PET is a polymer material with high cleanliness, low surface freedom, poor wetting and hydrophilicity, which is the fundamental reason for the poor hydrophilicity of PET dust-free cloth.

The surface of textile fibers can be modified using a plasma surface cleaning machine to improve the hydrophilicity of PET dust-free cloth. Usually, a certain surface modification treatment is used. Plasma surface modification uses a plasma surface cleaning machine, which can not only retain the original excellent properties of PET dust-free cloth, but also significantly improve its hydrophilicity.

After being processed by the plasma cleaning machine, lay the dust-free cloth on the table and inject the blue transparent reagent solution onto the dust-free cloth again. 

At this point, the reagent solution can be placed on the table, and the PET dust-free cloth can be quickly spread out. At this point, compared to before plasma surface treatment, the hydrophilicity of the dust-free cloth has significantly improved.

The plasma activation treatment of PET introduces a large number of polar functional groups into the surface of the dust-free cloth. 

The more functional groups there are, the higher the surface freedom of the dust-free cloth, and the better the wettability and hydrophilicity. In addition, the surface of PET dust-free cloth in plasma cleaning machine can achieve micro corrosion, which not only retains its inherent excellent performance, but also increases surface roughness and improves its hydrophilicity. The PET plasma surface modification process is also applicable to material treatment.

In addition, in order to improve the bonding effect, plasma cleaning equipment can increase the surface roughness and effectively remove interface pollutants before bonding, usually taking only a few seconds to effectively remove these organic pollutants. At the same time, plasma cleaning machines can also undergo complex chemical reactions on the surface of activated materials through the introduction of reactive gases, producing carbon oxides, amino groups, carboxyl groups, etc. 

These are all active factors that can effectively improve the surface activity of materials and enhance surface roughness without damaging the material foundation.

The plasma surface cleaning machine can precisely control the degree of surface modification by adjusting parameters such as gas type (such as Ar, O ?, N ?, CF ?, etc.), power, processing time, etc. The applicability of the plasma cleaning machine is very wide. In addition to being suitable for textile fibers, it can also be applied to materials such as polypropylene (PP), polyester (PET), nylon (PA), etc., without affecting the properties of the material itself.

The plasma cleaning modification effect mainly focuses on the surface (nanometer to micrometer level), has no effect on the internal properties of the material, and has a high equipment cost. Plasma processing machines (such as online vacuum plasma and atmospheric pressure plasma generators) are suitable for large-scale production, with simple operation and good performance.
