In Europe, a research team has recently successfully developed an innovative bio-based dual-layer encapsulation strategy. Utilizing β-cyclodextrin and L-arginine, they have produced cotton fabric with flame-retardant, antibacterial, and hydrophobic properties, aiming to meet application demands in various fields.

The core of this strategy lies in using β-cyclodextrin and L-arginine as key components to modify cotton fabric through a dual-layer encapsulation structure. β-cyclodextrin is a naturally derived cyclic molecule with good inclusion properties and stability, while L-arginine is an amino acid that can effectively enhance the bioactivity of materials. By combining these two substances, the researchers have achieved functional enhancement of the cotton fabric.

The treated cotton fabric exhibits significant flame-retardant properties, capable of delaying flame spread in high-temperature environments and improving safety performance. Simultaneously, its antibacterial function helps inhibit bacterial growth, making it suitable for medical and hygiene-related scenarios. The hydrophobic property endows the fabric with water-repellent capability, extending its service life and enhancing comfort.

This dual-layer encapsulation strategy based on β-cyclodextrin and L-arginine not only simplifies the production process but also reduces environmental impact, aligning with sustainable development trends. The research team stated that this technology is expected to find wide application in the apparel, home furnishing, and industrial sectors, promoting textile innovation.
