Summary
Researchers developed smart textiles from recycled cotton waste. These novel fabrics exhibit reversible photochromic and fluorescent properties, offering durable and stable color changes under UV light.
Area of Science:
- Materials Science
- Textile Engineering
- Nanotechnology
Background:
- Cotton is a versatile natural fiber with desirable properties but faces demand for sustainable alternatives.
- Smart textiles that change color with light stimulus are gaining interest for various applications, including UV sensing.
- Recycled cotton waste presents an underutilized resource for developing novel textile materials.
Purpose of the Study:
- To develop a novel method for creating luminescent and photochromic nonwoven textiles from recycled cotton waste.
- To investigate the feasibility of using screen-printing technology with inorganic phosphor nanoparticles for textile functionalization.
- To evaluate the colorimetric and photoluminescent properties, as well as the durability of the developed smart textiles.
Main Methods:
- Utilized screen-printing technology to apply an aqueous printing paste containing inorganic phosphor nanoparticles (10-18 nm) onto recycled cotton nonwoven fabric.
- Characterized the colorimetric properties using CIE Lab color coordinates.
- Analyzed photoluminescence spectra to confirm emission characteristics under ultraviolet (UV) light (365 nm).
Main Results:
- Successfully developed a cotton fabric exhibiting reversible green emission (519 nm) under UV light.
- Achieved photochromic and fluorescent properties even at a low pigment concentration (2%) in the printing paste.
- Demonstrated high durability and photostability of the colorfastness in the printed fabrics.
Conclusions:
- Recycled cotton waste can be effectively transformed into functional smart textiles with photochromic and fluorescent capabilities.
- Screen-printing with inorganic phosphor nanoparticles offers a viable method for creating advanced textiles with tunable optical properties.
- The developed smart textiles show potential for applications requiring UV responsiveness and durable color-changing functionalities.
