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 disclosed a launderable bactericidal and virucidal fabric finish, but it had limitations in terms of wash durability, treatment time, and fabric properties. The present invention solves these problems by introducing novel formulations and methods that provide improved performance and functionality.

Novelty and Inventive Step

The new invention's novelty lies in the combination of improved wash durability, accelerated treatment times, and enhanced fabric properties, which are achieved through the use of novel formulations and methods. The inventive step resides in the identification of specific crosslinkers, catalysts, transition metal salts, and additives that provide the desired improvements, as well as the development of a system for continuous production of launderable bactericidal and virucidal fabrics.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include the use of different crosslinkers, catalysts, transition metal salts, and additives, as well as variations in the formulation compositions and treatment methods. Additionally, the invention could be adapted for use with different types of fabrics, such as cotton, polyester, or blends.

Potential Commercial Applications and Market

The present invention has significant commercial potential in the textile industry, particularly in the production of medical, healthcare, and hygiene-related products. The invention's improved performance and functionality make it an attractive solution for companies seeking to develop high-quality, bactericidal and virucidal fabrics for various applications.

Field of Art

Textile chemistry, antimicrobial fabric treatments, and chemical modification of textile surfaces, involving expertise in organic chemistry, materials science, and microbial control technologies

Person of Ordinary Skill (PHOSITA) Profile

A professional with a graduate degree in chemistry or materials science, familiar with textile treatment techniques, antimicrobial agent design, and chemical modification strategies for fabric surfaces

Obviousness Rationale

A PHOSITA would recognize that the PTD's variations represent predictable engineering improvements to the source patent's bactericidal fabric treatment method. The disclosed modifications involve standard techniques of adjusting crosslinkers, catalysts, and treatment parameters that would be well-understood within the textile chemistry domain. The incremental enhancements in wash durability, treatment time, and fabric properties represent routine optimization strategies known to practitioners in antimicrobial textile technologies.
