Polyester Fabric with Fluorescent Properties Using Microwave Technology for Anti-Counterfeiting Applications.

Area of Science:

• Materials Science
• Textile Engineering
• Analytical Chemistry

Background:

• Counterfeiting is a significant issue in the textile industry, necessitating advanced identification methods.
• Fluorescent materials offer potential for secure labeling and authentication of products.
• Polyester fabrics are widely used but require effective methods for anti-counterfeiting applications.

Purpose of the Study:

• To investigate the application of fluorescein as a fluorescent material for anti-counterfeiting in the textile sector.
• To develop a method for labeling and identifying legitimate textile articles using fluorescein.
• To evaluate the effectiveness of fluorescein in detecting counterfeit textiles.

Main Methods:

• Application of fluorescein to polyester fabrics using microwave irradiation.
• Incorporation of a UV absorber into the fluorescent solution.
• Morphological characterization using Scanning Electron Microscopy (SEM).
• Quantitative analysis using optical spectroscopy (reflectance and transmission).

Main Results:

• Fluorescein-treated polyester samples exhibit a yellowish-green emission under UV light.
• The microwave irradiation technique successfully applied fluorescein to the textile substrate.
• UV absorbers improved the light resistance of treated samples by 25%.
• The method allows for detectable fluorescence under specific UV excitation wavelengths.

Conclusions:

• Fluorescein is an effective fluorescent material for anti-counterfeiting technology in textiles.
• The developed method enables secure labeling and identification of legitimate articles.
• The addition of UV absorbers enhances durability and provides UV protection to the fabric.
