袜口约束失效过程中对应腿部受压的研究

Research on Compression on Legs in the Process of Hose Top Constraint Failure

文章选用40种不同规格短袜作为实验原料,然后挑选20位测试者进行穿着,在穿着的袜子上选择4个不同位置,利用A-0505型接触压计进行对应腿部所受压强的测试,通过对测试数据进行系统分析。结果表明:袜子出现袜口约束失效的过程中,具有双层结构、口长较小和袜筒上口宽与口宽的差值比较大的袜子,在袜口处对应腿部所受到的压力更大,更容易感到紧绷。袜口约束失效过程中腿部受压情况和袜口结构的特征为:袜子前中处的压强普遍大于2.00kPa,袜口两层之间的结合处存在突出,且口长小于20mm,袜筒上口宽和口宽的差值大于10mm。

For purpose of this paper,socks of 40 different specifications were chosen for experiment,20 subjects were chosen to wear the socks,the intensity of pressure on four positions of legs wearing socks was tested with A-0505 contact pressure gauge,and systematic analysis was carried out based on the test data.The results show that the pressure on legs wearing socks of two-layer structure,with short hose top,and with large difference between the hose top width and mouth width is larger and feel tighter in the process of hose top constraint failure.The characteristics of pressure on legs and hose top structure in the process of hose top constraint failure are：the intensity of pressure on the center front part of socks is larger than 2.00 kPa,the joint of the two layers of hose top extrudes,the hose top length is less than 20 mm,and the difference between the hose top width and mouth width is larger than 10 mm.
