This study examines the performance level of hybrid woven protective clothing (HWPC), manufactured from Kevlar® (K) and Ramie (R) yarns. The weave structures (plain, twill 1/3) and variables fiber ratios were used to produce HWPC. The performance level of HWPC was measured according to EN 388:2016. We came to the conclusion that blade cut resistance of plain and twill structure sustained protection level up to increase of KR 80:20 and KR 70:30, respectively; puncture resistance of K100% and HWPC remained in the same level of protection for plain and twill weaves; Abrasion resistance of K100% and HWPC of plain and twill weaves samples presented abrasive performance of same protection level, but the average number of cycles sustained for twill weave samples was slightly higher than plain weave. However, comparing the plain and twill weaves sample for tear resistance, twill weave samples have higher tear resistance than plain weave. A gray relational analysis and Taguchi method was performed to optimize the performance of two structures with variable fiber ratios. It was established that the article produced with K&R yarns with KR 80:20 ratio and twill weave presented the best performance against all test runs. The main objective of this study is to reduce plastic pollution by reducing the amount of synthetic fiber proportion in personal protective clothing and thereby reducing the dependence on nonrenewable sources for synthetic fiber. The 41 g/m reduction of Kevlar® fiber has been made in a conventional PC with ramie fiber, without compromising the protection level. This will enhance the sustainability of HWPC.
本研究考察了由凯夫拉®（K）和苎麻（R）纱线制成的混合编织防护服（HWPC）的性能水平。使用不同的织物结构（平纹、斜纹 1/3）和纤维比例变量来生产 HWPC。HWPC 的性能水平根据 EN 388：2016 进行测量。我们得出结论，平纹和斜纹结构的刀片切割阻力可持续保持保护水平，分别增加 KR 80:20 和 KR 70:30；K100%的穿刺阻力和 HWPC 的平纹和斜纹织物保持相同的保护水平；K100%和 HWPC 的平纹和斜纹织物样品的耐磨性呈现出相同的防护水平的耐磨性能，但斜纹织物样品的平均循环次数略高于平纹织物。然而，对于撕裂强度，与平纹织物相比，斜纹织物的撕裂强度更高。采用灰色关联分析和 Taguchi 方法对两种纤维比例可变的结构进行了性能优化。结果表明，采用 KR 80:20 比例的 K 和 R 纱线生产的平纹斜纹织物在所有测试运行中表现出最佳性能。本研究的主要目的是通过减少个人防护服中合成纤维的比例来减少塑料污染，从而减少对不可再生合成纤维资源的依赖。在传统的 PC 中，减少了 41 克/平方米的 Kevlar®纤维，同时保持了保护水平不变。这将提高 HWPC 的可持续性。
