摘要:
针对目前关于人体出汗的研究均未涉及到女性胸部出汗的细化,从而导致关于女性文胸热湿优化设计并无科学的出汗率数值参考的问题,探究了青年女性胸部出汗分布规律、局部出汗率差异和整体出汗率大小。实验选取15名青年女性受试者,在温度为26 ℃、相对湿度为50%的环境下,采用本文提出的新型“三明治”结构吸汗贴测定胸部整体出汗率,进行代谢率为50~60 W/m2的静坐和系列代谢率为200~250 W/m2的中高强度运动,随后得到胸部出汗分布规律,测定出胸部非显性出汗率、显性出汗率、不同区域出汗率和不同运动阶段出汗率的变化规律。结果表明:显性出汗过程中,乳房中心点(BP点)周围环状区域、胸部边缘环状区域(尤其靠近前中)的出汗率相对较高并较先出汗;静坐状态下胸部非显性出汗率为(0.004 7±0.003 7) mg/(min·cm2),中高强度运动状态下胸部显性出汗率为(0.405 5±0.178) mg/(min·cm2); 局部区域显性出汗率中,靠近前中的胸部出汗率最大为1.844 mg/(min·cm2),其次是BP点周围为0.664 mg/(min·cm2), 再是胸部上边缘和下边缘。此出汗分布规律可指导文胸罩杯结构优化和通风透气孔分布设计,胸部出汗率可为文胸罩杯材料透湿性能指标的选择和新材料开发提供理论参考,助力企业开发新型透湿性能卓越的文胸产品。
