Abstract

AbstractThe burning and melting of elastic fastening bands in high-temperature environments are major contributors to empyrosis and ambustion owing to their snug fit to human body parts in practical usage. Conventionally fabricated fastening bands show poor degradation, negative environmental impact, and poor flame-retardant performance. Herein, we report an ecofriendly cyclic phosphate ester-based flame-retardant polylactic acid (PLA) elastic band prepared using an impregnation-baking process, and experimental investigation was conducted on the optimized finishing process. The band was characterized using scanning electron microscopy, energy-dispersive spectroscopy, and thermogravimetry. The band exhibited a damage length of 3.9 cm after vertical combustion and self-extinguishing effect after being removed from the fire source without generating molten droplets. The cross-linking phenomenon between the modified PLA fibers was beneficial in improving the flame retardancy of the PLA elastic band in the condensed phase. The strength loss of the band was <5%. Thus, the prepared band can be widely used in real-world applications.Keywords: Antidrippingbakingblast dryercross-linkinggraphitizationorganophosphorus Disclosure statementThe authors report there are no competing interests to declare.Additional informationFundingThis work was supported by the National Key Research and Development Program of China under Grant number 2019YFA0706900 and Jiangsu Provincial Policy Guidance Programme-International Cooperation Projects under Grant number BZ2020010.

热防护服用阻燃聚乳酸松紧带的研制及性能分析

摘要:弹性扣带在实际使用中由于与人体部位贴合较紧，在高温环境中极易发生燃烧、熔化等现象，是造成烧伤和伏击的主要原因。传统制造的紧固带具有较差的降解性、对环境的负面影响和较差的阻燃性能。本文报道了采用浸渍-烘烤法制备环保型环磷酸酯基阻燃聚乳酸(PLA)弹性带，并对优化后的整理工艺进行了实验研究。利用扫描电子显微镜、能量色散光谱和热重法对其进行了表征。垂直燃烧后条带损伤长度为3.9 cm，离开火源后条带具有自熄作用，且不产生熔滴。改性PLA纤维之间的交联现象有利于提高PLA弹性带在缩合相的阻燃性。带强度损失<5%。因此，制备的带可以广泛应用于实际应用中。关键词:防滴漏;烘培;鼓风干燥机;交联;本研究得到国家重点研发计划项目(资助号:2019YFA0706900)和江苏省政策指导计划国际合作项目(资助号:BZ2020010)的支持。

期刊介绍： The Journal of The Textile Institute welcomes papers concerning research and innovation, reflecting the professional interests of the Textile Institute in science, engineering, economics, management and design related to the textile industry and the use of fibres in consumer and engineering applications. Papers may encompass anything in the range of textile activities, from fibre production through textile processes and machines, to the design, marketing and use of products. Papers may also report fundamental theoretical or experimental investigations, including materials science topics in nanotechnology and smart materials, practical or commercial industrial studies and may relate to technical, economic, aesthetic, social or historical aspects of textiles and the textile industry. All published research articles in The Journal of The Textile Institute have undergone rigorous peer review, based on initial editor screening and anonymized refereeing by two expert referees.
