Summary
This study introduces a green atmospheric plasma treatment to improve polylactic acid (PLA) fiber dyeing. The eco-friendly method enhances fiber hydrophilicity and dye binding, overcoming PLA
Area of Science:
- Materials Science
- Polymer Chemistry
- Surface Engineering
Background:
- Polylactic acid (PLA) fibers exhibit poor dyeing performance due to a lack of active chemical groups, limiting their use.
- Conventional chemical modification methods for PLA are often environmentally unfriendly, generating effluents.
Purpose of the Study:
- To develop a green, efficient, and continuous method for improving PLA fiber hydrophilicity and dyeing performance.
- To investigate the mechanisms of enhanced dye binding on plasma-modified PLA fibers.
Main Methods:
- Surface diffuse atmospheric plasma treatment of PLA fibers.
- Grafting of oxygen-containing functional groups (e.g., carboxyl) onto the PLA fiber surface.
- Analysis of hydrophilicity and dye binding interactions (covalent, ionic, hydrogen bonds).
Main Results:
- Atmospheric plasma treatment successfully introduced oxygen-containing functional groups, enhancing PLA fiber hydrophilicity.
- Improved dye uptake and binding strength were observed due to enhanced interactions between dyes and modified PLA fibers.
- The plasma process is efficient, continuous, and avoids chemical additives.
Conclusions:
- Green atmospheric plasma surface modification is a viable and eco-friendly approach to enhance PLA fiber dyeing performance.
- This method offers potential for broader applications of PLA in fields requiring improved material properties and coloration.
