**Vapor Phase Infiltration (VPI) for multifunctional and antimicrobial
textile**
Natalia Chamorro
Post-doctoral Researcher, Nanomaterials, CIC nanoGUNE
The growing demand for functionality and connectivity in the textile industry
has motivated the development of textile products based on nanotechnology. The
textile industry is seeking materials with a wide range of exciting new
applications such as self-cleaning, antibacterial, anti-odor, etc., ideally at
the same time. One of the very promising strategies to implement such
properties into textiles is the application of vapor phase chemistry to the
manufactured textile.
In this work, we present our strategy to functionalize textiles with a mixed
composition, namely denim jeans (a mix of cotton and polyethylene fibers) with
the incorporation of TiO2, ZnO, and Al2O3 by applying vapor phase infiltration
(VPI). Not only we demonstrate the utility of the VPI technique, but we also
investigate the stability of the chemical structure and properties of the
hybrid material under long-term use conditions.
We show that the VPI process can have a very positive impact on the wetting,
UV blocking and antimicrobial properties of the textile. Furthermore, the
durability of the hybrid fabrics has been investigated by simulated washing
processes to demonstrate the applicability of the approach in real life.
Further important properties of the hybrid textile materials are currently
being evaluated.
