A comprehensive investigation of the properties of poly(paraphenylene-1,3,4-oxadiazole) fibers showed that items based on them were dimensionally stable during operation up to 400°C and retained high strength indicators after prolonged action of soil microorganisms. The fiber tensile strength remained at 78-80% after exposure to light for 2,000 h; at 93-95%, if a stabilizer was added. The investigation results predict high retention of mechanical properties of cloth based on Arselon® fiber during operation of items made from them under Russian Northwest and similar conditions.

纺织品专用聚对苯并-1,3,4-恶二唑纤维的性能研究与分析

聚（对亚苯基-1,3,4-恶二唑）纤维的性能的综合研究表明，基于它们的纤维在高达400°C的温度下操作期间尺寸稳定，并且在土壤微生物长时间作用后仍保留了高强度指标。暴露2000小时后，纤维的拉伸强度保持在78-80％。如果添加稳定剂，则为93-95％。研究结果预测，在俄罗斯西北地区和类似条件下，使用Arselon®纤维制成的布料在其制成的物品运行期间会保留较高的机械性能。
