Regulations on waste are expected to become rigorous due to environmental pollution and resource depletion, which will make recycling of textile waste more important both industrially and socially. Research has been conducted to recycle waste fibers, but there is still a lack of fundamental and experimental understanding of fiber structure after base or acid or enzyme treatment. Complex reaction mechanisms, including swelling processes and interactions between textiles and chemicals, and various surface functional groups (i.e., bulk fibers and microfibers) of chemically treated products are all deweaving. Until now, there is a lack of spectroscopic and microscopic data to understand the structure and morphology of lung fibers. Because structural analysis due to the complexity and diversity of clothing and fiber structures is not performed accurately, material structure analysis using state-of-the-art optical microscopy methods is required. We propose eco-friendly thermal, chemical, physical and enzyme use methods that can economically regenerate waste fibers and antiquities and be used as raw materials for next-generation fiber production. Currently, domestic consumers are less willing to buy recycled clothing materials, and there is a lack of understanding of the exact requirements for actual buyers and users of recycled textile waste clothing products. Recycling, a sustainability trend aimed at environmental conservation and resource conservation, can be limited to the perspective of pursuing aesthetics by emphasizing low growth and ethical responsibility.
Negative images of recycled products are still in place. Therefore, it is necessary to plan and design products centered on consumer preferences and emotions to improve consumers' positive perception of recycled clothing material products and their purchasing intentions. The development and production of sustainable textile and clothing products requires company-wide participation and collaboration from design to planning, quality, marketing, etc. Design is at the center of sustainable product development as well as technology, and no matter how good the technology is, it cannot be a good technology unless you understand the user first. However, so far, most product development processes have been mainly conducted from the perspective of technology developers, and consumers' perception of recycled clothing products is negative and their intention to use them is not active. To overcome these limitations, this study developed excellent physical properties through the development of textile waste recycling technology (science and engineering), analyzed trend information based on consumer preference analysis, global marketing demand survey.
Research on the decomposition of cotton fabrics has been carried out continuously while changing chemical (non-toxic chemical use target), thermal (low temperature reaction target), and physical (low energy consumption target) conditions. Despite the difficulties of COVID-19, successful results were calculated in participating in domestic and foreign academic conferences and publishing papers aimed at during the research period. The goal is to design and brand products that utilize recycled and recycled textile waste materials, and to present commercially available products. Based on collecting fashion trend information and analyzing sustainable fashion status, we developed a brand called NOTTOC. Based on the identity, pursuit value, logo, character, and motif of the " NOTTOC" brand, we created a design sample book by dividing it into fashion clothing, fashion miscellaneous goods, and living products. Based on consumer surveys, we made actual design prototypes. Based on the results of the Sustainable Fashion Brand and Product Trend Survey and Consumer Survey, we proposed sustainable brand concepts and logos developed in the second year to corporate experts and consumers to conduct interviews and surveys. We collected this and applied it to future design development and branding, branding the developed products in the third year, and published a U.S. consumer survey on sustainable distribution channels and a big data paper on street fashion with potential marketability related to sustainable brands. Finally, this research developed a technology to resource domestic and foreign textile waste through chemical recycling, and designed and commercialized it as a user-centered product.
