Abstract
Para-aramid fibers, known for their remarkable strength and thermal stability, are frequently employed in protective textiles for military and aerospace applications. However, continuous exposure to ultraviolet (UV) radiation can damage their protective characteristics. This study analyzes the ultraviolet protection factor (UPF) and UV transmittance of woven fabrics produced from 30/2 Ne spun para-aramid yarns in the warp and 10 Ne core-spun yarns in the weft. The weft yarns consisted of three sheath fibers-para-aramid, meta-aramid, and polyester-in combination with different specialty core materials. The results show significant differences in UPF before and after UV exposure, with para-aramid sheaths giving the highest improvement. UV exposure caused structural changes in the fibers, resulting in increased UV protection, particularly in fabrics with para-aramid sheaths. This study concludes that the combination of para-aramid fibers with specific core materials significantly enhances UV protection, making them well-suited for applications in high UV exposure environments.
对位芳纶纤维以其出色的强度和热稳定性而著称,经常被用于军事和航空航天应用的防护纺织品中。然而,持续暴露在紫外线(UV)辐射下会破坏其防护特性。本研究分析了由 30/2 Ne 对位芳纶经纱和 10 Ne 包芯纱纬纱制成的机织物的紫外线防护系数(UPF)和紫外线透过率。纬纱由对位芳纶、间位芳纶和聚酯三种护套纤维与不同的特种芯材组合而成。结果显示,UPF 在紫外线照射前后有明显差异,对位芳纶鞘纤维的改善幅度最大。紫外线照射导致纤维结构发生变化,从而提高了防紫外线性能,尤其是对位芳纶护套织物。这项研究的结论是,对位芳纶纤维与特定芯材的结合可显著增强紫外线防护能力,使其非常适合应用于紫外线照射较强的环境中。
期刊介绍:
Polymers (ISSN 2073-4360) is an international, open access journal of polymer science. It publishes research papers, short communications and review papers. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Polymers provides an interdisciplinary forum for publishing papers which advance the fields of (i) polymerization methods, (ii) theory, simulation, and modeling, (iii) understanding of new physical phenomena, (iv) advances in characterization techniques, and (v) harnessing of self-assembly and biological strategies for producing complex multifunctional structures.
