This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,953.

Background and Problem Solved

The original patent provides a launderable bactericidal and virucidal fabric finish, but it has inherent limitations, such as reduced efficacy after repeated washing, lack of real-time monitoring, and limited durability. The present invention solves these problems by introducing a system for enhancing the launderability, a method for improving durability, and a composition with enhanced molecular mimicry.

Novelty and Inventive Step

The present invention's novelty lies in the integration of real-time monitoring, nanofiltration, and low-temperature plasma treatment to enhance the launderability and durability of the fabric finish. The inventive step is the synergistic combination of these elements, which provides a significant improvement over the original patent.

Alternative Embodiments and Variations

Alternative embodiments include using different types of fabric treatment modules, such as ultrasonic or microwave-based systems, or incorporating additional sensors to monitor fabric finish properties. Variations of the composition could include different ratios of crosslinkers and catalysts or the use of alternative beta-cyclodextrin-based agents.

Potential Commercial Applications and Market

The present invention has significant commercial potential in the textile and healthcare industries, particularly in the development of medical-grade fabrics, personal protective equipment, and high-performance sportswear. The market demand for such products is increasing, driven by growing concerns about public health and safety.
