Summary
This study enhances polyester (PET) fabric
Area of Science:
- Materials Science
- Textile Chemistry
Background:
- Polyester (PET) fabrics exhibit hydrophobicity, limiting their dyeability and comfort.
- Developing eco-friendly surface modification techniques is crucial for sustainable textile processing.
Purpose of the Study:
- To improve the surface properties of PET fabric for enhanced coloration and functionality.
- To investigate the combined effect of plasma treatment and cationization on PET fabric.
Main Methods:
- PET fabric was treated with three different plasma gases followed by cationization using quaternary ammonium salt (Quat 188).
- Natural dyes from madder roots were used for dyeing and printing applications.
- Color strength (K/S), wettability, tensile strength, and roughness were evaluated.
Main Results:
- Nitrogen plasma treatment prior to cationization significantly improved PET fabric coloration.
- The combined nitrogen plasma and cationization technique enhanced surface properties, including wettability and tensile strength.
- Optimized nitrogen plasma treatment at 3 l/min yielded superior results.
Conclusions:
- The eco-friendly plasma and cationization method effectively modifies PET fabric surface properties.
- This approach offers a sustainable route for improved dyeing, wettability, and mechanical performance of PET textiles.
- Nitrogen plasma combined with cationization is a promising technique for advanced textile functionalization.
