Summary
This study developed durable, submicron multilayer microcapsules using chitosan and sodium dodecyl sulfate. Applied to plasma-treated polyester fabric, these microcapsules demonstrate excellent wash durability due to ionic interactions.
Area of Science:
- Materials Science
- Textile Chemistry
- Surface Chemistry
Background:
- Developing functional textiles requires durable surface modifications.
- Microcapsule technology offers potential for imparting new properties to fabrics.
- Chitosan and sodium dodecyl sulfate are biocompatible polymers suitable for microcapsule formulation.
Purpose of the Study:
- To develop and characterize multilayer microcapsules using chitosan (Chi) and sodium dodecyl sulfate (SDS).
- To investigate the application and wash durability of these microcapsules on polyester (PET) fabric.
- To evaluate the effect of air atmospheric plasma treatment on PET fabric's surface properties for enhanced microcapsule adhesion.
Main Methods:
- Multilayer microcapsules were synthesized via combined emulsification and phase coacervation with 11 alternate Chi/SDS additions.
- Microcapsules underwent alkali treatment and were applied to PET fabric using a padding process.
- PET fabric surface modification was achieved through air atmospheric plasma treatment.
- Characterization involved Zeta potential, XPS, wetting measurements, SEM, and AFM with surface roughness analysis.
Main Results:
- Submicron-sized multilayer microcapsules with desired morphology were successfully developed after alkali treatment.
- Plasma treatment activated the PET fabric surface, promoting enhanced microcapsule adhesion.
- Various characterization techniques confirmed the wash durability of the microcapsules on the treated PET fabric.
- Ionic interactions between chitosan-based microcapsules and the activated PET surface were identified as key to durability.
Conclusions:
- The developed multilayer microcapsules are suitable for textile applications, offering enhanced functionality.
- Plasma pre-treatment of PET fabric significantly improves the wash durability of chitosan-based microcapsules.
- The study demonstrates a viable method for creating durable functional textiles through microcapsule technology and surface modification.
