Utilization of monochloro-triazine β-cyclodextrin for enhancing printability and functionality of wool

Area of Science:

• Textile Chemistry
• Materials Science
• Nanotechnology

Background:

• Wool fabric modification is crucial for improving its functional properties.
• β-cyclodextrin (βCD) derivatives offer unique host-guest complexation capabilities.
• Antibacterial treatments for textiles are in high demand.

Purpose of the Study:

• To modify wool fabric using Monochloro-triazine β-cyclodextrin (MCT-βCD).
• To evaluate the impact of MCT-βCD modification on post-printing and antibacterial properties.
• To investigate the effectiveness of subsequent treatments with silver nanoparticles (Ag-NPs) or triclosan derivatives.

Main Methods:

• Wool fabric pre-modification with MCT-βCD.
• Post-printing treatments with various dyestuffs.
• After-treatment with Ag-NP colloid or triclosan derivatives.
• Assessment of printing quality and antibacterial activity.
• Washing durability tests (15 cycles).

Main Results:

• MCT-βCD successfully modified wool fabric structure.
• Modified wool showed improved post-printing performance and significant antibacterial activity.
• Antibacterial properties were retained above 75% after 15 washing cycles.
• Property enhancement depended on modification degree, dyestuff fixation, and antibacterial agent loading.

Conclusions:

• MCT-βCD is an effective agent for enhancing wool fabric's printing and antibacterial functionalities.
• The guest-host complexation of βCD moieties and wool's active sites contribute to improved properties.
• The developed treatment sequence offers durable antibacterial performance for modified wool textiles.
