Abstract: With the global advancement of environmental protection awareness, the textile industry is facing significant challenges. Traditional textile functional finishing agents are under strict regulation due to their negative impact on the environment. At the same time, consumers' demand for healthy textiles is also increasing, gradually relying on scientific research to bring functionality, health, and applicability to textile and apparel products.
The study aimed to develop a healthy, environmentally friendly and multifunctional textile fabric. Mulberry silk was chosen as the warp material, with silk and modified soy protein fiber being used as weft materials. To deeply investigate the impact of different mass fractions of fibers and fabric structures on the performance of the fabric, 15 groups of fabrics with different specifications were woven for trial. Among them, nine groups of fabrics were woven with different weft insertion ratios of the two types of weft yarns with the weft insertion ratios of the soy protein fiber to silk being: 0:1, 1:4, 1:2, 1:1, 2:1, 3:1, 4:1 and 1:0. Six groups were woven with different fabric structures, namely weft backed weave, twill weave, broken twill weave, five-heddle satin, eight-heddle satin, and honeycomb. The fabrics underwent tests for antibacterial properties and far-infrared emission performance, and regression equations were used to analyze the experimental data to reveal the relationship between various parameters and performance. The results show that as the mass fraction of modified soy protein fiber in the weft increases, the antibacterial properties of the fabric gradually enhance. This is mainly attributed to the natural antibacterial components in modified soy protein fibers, oligosaccharides, and saponins. Similarly, as the mass fraction of modified soy protein fibers in the weft increases, the far-infrared emission properties of the fabric also improve. This characteristic helps to improve human microcirculation and increase wearing comfort. Compared with previous literature and research, the conclusions drawn from this study are consistent with previous results and further verify the potential of protein fibers in environmentally friendly and multifunctional textile fabrics.
The study has successfully developed a healthy, environmentally friendly, and multifunctional textile fabric. Experimental results indicate that protein fibers, especially plant-based protein fibers, have great potential in functional development. Future research can further explore the application of different types of protein fibers and their combinations in textile fabrics, aiming to develop more diverse and superior-performing eco-friendly fabrics.
