Health hazards and environmental pollution are major concerns in present world. So, it is high time to think about ecofriendly and sustainable production. In this study, pumpkin juice has been used as an ecofriendly flame retardant finish to enhance the functionality of cotton twill fabric. The pumpkin juice extracted from the fresh pumpkin without any chemicals. The cotton fabric was treated with pumpkin juice in exhaust method. The treated and untreated samples were characterized by TGA, FTIR, SEM, and EDX. The flame-retardant property of the samples were evaluated based on the LOI and vertical flame tester. The result demonstrated that the treated samples exhibited high fire-retardant properties after being finished with pumpkin juice. The LOI value of the treated samples increased to 29 from 19 after treatment. The main reason behind the increased flammability is the dehydration of pumpkin juice-treated fabric which was clarified from the TG analysis. Moreover, the FTIR, SEM, and EDX report ensured the presence of bound and unbound water molecules, different salt, and several atoms in the samples treated with pumpkin juice that enhanced the protection against the spreading of the fire and thus improved fire-retardant properties of the treated samples.
健康危害和环境污染是当今世界的主要关注点。因此，是时候考虑生态友好型和可持续生产了。在本研究中，南瓜汁被用作一种生态友好型阻燃整理剂，以增强棉斜纹织物的功能。从新鲜南瓜中提取的南瓜汁未添加任何化学物质。棉织物采用浸轧法用南瓜汁进行处理。对处理过和未处理的样品进行了热重分析（TGA）、傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）和能谱分析（EDX）表征。基于极限氧指数（LOI）和垂直燃烧试验仪对样品的阻燃性能进行了评估。结果表明，用南瓜汁整理后的处理样品表现出高阻燃性能。处理后样品的LOI值从19提高到了29。燃烧性增加背后的主要原因是南瓜汁处理过的织物脱水，这从热重分析中得到了澄清。此外，傅里叶变换红外光谱、扫描电子显微镜和能谱分析报告证实，在用南瓜汁处理的样品中存在结合水和未结合水分子、不同的盐以及几种原子，这些增强了对火灾蔓延的防护，从而提高了处理样品的阻燃性能。
