Pressure distribution and comfort pressure range of men′s seamless underwear

120 young men of different body sizes were selected to wear seamless underwears made of the same material and style,but different cylinder diameters,weaves and knitting methods under static condition.The seamless underwear pressure on different positions of the upper body was tested,and the wearers were required to give subjective evaluation of pressure comfort.Fuzzy mathematics,box control graph and other statistical methods were used to analyze the subjective and objective experimental data.The pressure distribution rule and comfort pressure range of the underwears were got.The results showed that on elbow,side part,armhole and back,young men are very sensitive to objective pressure′ s variation.Though the objective pressure on forearm and upper arm is large,subjective evaluation is comfort.On the contrary,the object pressure on chest is small,the subjective evaluation is bad.The reason is that pressure affordability varies with body parts.It is suggested that the pressure on armhole,back and chest should be decreased as much as possible when designing men′s seamless underwears.
