The growing global emphasis on environmental issues has driven companies to exert greater efforts on making their products more sustainable. Natural dyeing, an eco-friendly dyeing method used in the textile and apparel industry, is safer for both the environment and human health, aligning with the needs of sustainable design development. This paper examines the key factors affecting Chinese consumers’ satisfaction with naturally dyed garments, aiming to provide research-based strategies for the design and development of such garments. In this study, we utilized the KJ method for the detailed categorization of the functionalities of naturally dyed garments, establishing five dimensions and thirty demand indicators. Based on this, the KANO model, coupled with the Better–Worse coefficient and the quadrant analysis method, was used to classify different demand items, ranking their satisfaction and importance. The results indicate that the wearing experience and environmental characteristics of products are key determinants influencing Chinese consumers’ demand for naturally dyed clothing. The top five factors significantly impacting product satisfaction, in descending order of importance, are comfort, environmentally friendly dyeing techniques, safety, degradability, and durability. Therefore, to ensure consumer satisfaction with naturally dyed clothing, these factors should be prioritized when establishing a support system that caters to consumer needs. Our findings can help companies to better understand consumers’ actual need for naturally dyed garments, enabling the more targeted development and optimization of such garments, enhancing product competitiveness, and promoting the green transformation and sustainable development of enterprises. Simultaneously, this study also contributes novel theoretical approaches and ideas for future research on consumer demand.

“…Moreover, Samant et al [ 129 ] reported that dyed fabric obtained from Acacia catechu showed antibacterial activities against E. coli and S. aureus . The pigments extracted from food industry wastes have antibacterial and antifungal activity for use in textile and as wound bandages in medicine [ 130 , 131 , 132 , 133 ]. Hakim et al [ 134 ] suggested that the pigment obtained from Senegalia catechu can be applied on various foods such as apples and cookies and, therefore, can be used as an edible ink.…”

Various fruit and vegetable wastes, particularly peels, seeds, pulp, and unprocessed residues from the food industry, are abundant sources of antioxidants and essential antimicrobial agents. These valuable bioactive compounds recovered from the food industry have a great application in food, agriculture, medicine, and pharmacology. Food-derived natural antimicrobials offer advantages such as diminishing microbial loads and prolonging the shelf life of food products particularly prone to microbial spoilage. They not only enrich the foods with antioxidants but also help prevent microbial contamination, thereby prolonging their shelf life. Similarly, incorporating these natural antimicrobials into food packaging products extends the shelf life of meat products. Moreover, in agricultural practices, these natural antimicrobials act as eco-friendly pesticides, eliminating phytopathogenic microbes responsible for causing plant diseases. In medicine and pharmacology, they are being explored as potential therapeutic agents. This review article is based on current studies conducted in the last four years, evaluating the effectiveness of food-based natural antimicrobials in food, agriculture, medicine, and pharmacology.

“…Bubbles generated by cavitation act as reactors and their asymmetric implosion leads to various physical effects of microfluidics, including high-speed microjets and high-intensity shock waves inducing effective mixing or stirring, enhancing localized heat and mass transfer; and reducing particle size and agglomeration, and changing particle morphology [18]. There are many reports on the preparation of antibacterial materials via sonochemistry methods, such as in the hygiene of fresh agricultural products [19]; preparation of edible films [20]; green synthesis of antibacterial metal oxides [21]; development of active nanomedicines [22]; dyeing of fiber materials [23]; research on antibacterial scaffolds [24]; food packaging films [25]; sterilization methods in the food industry [26]; wastewater treatment [27]; and improvement of marine environments [28]. Various substrates have been chosen during the sonochemistry process; however, it has been relatively rare to use cellulose-based materials as the packaging materials via sonochemical technology until now.…”

Cellulose is used widely in antimicrobial packaging due to its abundance in nature, biodegradability, renewability, non-toxicity, and low cost. However, how efficiently and rapidly it imparts high antimicrobial activity to cellulose-based packaging materials remains a challenge. In this work, Ag NPs were deposited on the surface of carboxymethyl cellulose/starch/N’N Methylenebisacrylamide film using ultrasonic radiation. Morphology and structure analysis of as-prepared films were conducted, and the antibacterial effects under different ultrasonic times and reductant contents were investigated. These results showed that Ag NPs were distributed uniformly on the film surface under an ultrasonic time of 45 min. The size of Ag NPs changes as the reducing agent content decreases. The composite film demonstrated a slightly better antibacterial effect against E. coli than against S. aureus. Therefore, this work can provide valuable insights for the research on antimicrobial packaging.
