The objective of this study is to assess the effectiveness of hip protector pads utilizing warp knitted spacer fabrics treated with silicone and latex, specifically designed for hip protective applications. Three different types of warp knitted spacer fabrics and silicone- or latex-treated variants were evaluated in terms of transmitted force, compression resistance, and thermo-physiological comfort parameters. A drop weight impact tester with a real hip impact area was used to measure the force attenuation capacity of hip protective pads, yielding transmitted force values ranging from 14.39 to 31.83 kN under applied energies of 12.5 and 25.0 J. Compression resistance values varied from 219 to above 950 N, depending on the fabric structure and treatment. Air permeability of the fabrics ranged from 1300 to 6000 l/ms, thermal resistance values from 0.0355 to 0.0714 mK/W, and water vapor resistance values from 2.66 to 3.99 m Pa/W. The findings demonstrate that treated warp knitted spacer fabricsespecially both sides open-structured onesshowed higher force attenuation, moderate compression resistance, and improved breathability, making them suitable candidates for hip protective pads that combine protection with prolonged wear comfort.
本研究的目的是评估采用经硅酮和乳胶处理的经编间隔织物的髋部保护垫的有效性,这些织物是专门为髋部保护应用设计的。对三种不同类型的经编间隔织物以及经硅酮或乳胶处理的变体在传递力、抗压性和热生理舒适性参数方面进行了评估。使用具有真实髋部冲击面积的落锤冲击试验机来测量髋部保护垫的力衰减能力,在12.5和25.0 J的施加能量下,传递力值范围为14.39至31.83 kN。抗压值从219到950 N以上不等,这取决于织物结构和处理方式。织物的透气率范围为1300至6000 l/ms,热阻值为0.0355至0.0714 mK/W,水汽阻值为2.66至3.99 m Pa/W。研究结果表明,经过处理的经编间隔织物,特别是两侧开放式结构的织物,显示出更高的力衰减、适度的抗压性和改善的透气性,使其成为结合保护与长时间穿着舒适性的髋部保护垫的合适候选材料。
