Flexible and Robust Biomaterial Microstructured Colored Textiles for Personal Thermoregulation.

Area of Science:

• Materials Science
• Textile Engineering
• Biotechnology

Background:

• Wearable thermoregulation technologies offer energy savings and improved thermal comfort.
• Existing textiles face limitations in working temperature, comfort, and reliability.

Purpose of the Study:

• To develop a skin-friendly personal insulation and thermoregulation textile.
• To achieve passive heating and cooling with zero energy input using a single textile.

Main Methods:

• Fabrication of biomaterial microstructured fibers with inherent insulation properties.
• Incorporation of biocompatible phase-change materials into the fibers.
• Coating the fibers with polydimethylsiloxane for enhanced properties.

Main Results:

• The developed textile provides both passive heating and cooling capabilities.
• The material exhibits good thermal insulation, low thermal emissivity, and dyeability.
• Enhanced thermoregulation textile shows water hydrophobicity, mechanical robustness, and working stability.
• Slow heating/cooling rates contribute to improved thermal comfort.

Conclusions:

• The proposed thermoregulation textile offers a feasible and adaptive solution for personal thermal management.
• The technology enables scalable manufacturing for practical applications in wearable electronics and intelligent fabrics.
