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. 11,857,662.

Summary of the Inventive Concept

This inventive concept leverages the core technology of hair coloring compositions to develop a novel, sustainable textile dyeing system using monosaccharides, offering a more environmentally friendly and customized approach to textile coloring.

Background and Problem Solved

The original patent disclosed hair coloring compositions using monosaccharides, but it was limited to the hair care industry. The present inventive concept addresses the need for a more sustainable and customizable textile dyeing system, which is currently lacking in the textile industry. The new claims overcome the limitations of the original patent by applying the monosaccharide-based technology to textile dyeing, providing a solution that is both eco-friendly and adaptable to various textile materials and designs.

Detailed Description of the Inventive Concept

The sustainable textile dyeing system comprises a composition including a first monosaccharide having 2 to 4 carbon atoms and a second monosaccharide having 2 to 4 carbon atoms. This composition is substantially free of surfactants and has a pH of from 2 to 5, making it an environmentally friendly alternative to traditional textile dyes. The system can be used to create customized textile dyes by mixing the monosaccharides in various ratios and applying them to textile materials using digital printing techniques. The resulting textile materials exhibit improved colorfastness and durability.

Novelty and Inventive Step

The new claims introduce a novel application of the monosaccharide-based technology to textile dyeing, which is non-obvious compared to the original patent's focus on hair coloring compositions. The inventive step lies in the adaptation of the technology to the textile industry, overcoming the limitations of traditional textile dyes and providing a sustainable and customizable solution.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of monosaccharides, varying the ratio of the first and second monosaccharides, or incorporating additional components to enhance the colorfastness and durability of the textile materials. Other variations could involve using different digital printing techniques or applying the composition to various textile materials, such as cotton, polyester, or silk.

Potential Commercial Applications and Market

The sustainable textile dyeing system has significant commercial potential in the textile industry, particularly in the fashion and apparel sectors. The system's eco-friendly and customizable nature could appeal to environmentally conscious consumers and fashion brands seeking to reduce their environmental footprint. The market potential is substantial, with the global textile dyeing market projected to grow significantly in the coming years.
