摘要
采用HFB-1型织物凉感测试仪对12种印花试样进行持续凉感性能的客观测试,探究了温度、风速以及水分含量对织物凉感的影响。此外,采用了秩位排序法对织物的凉感强弱进行了主观评价。结果表明:锦纶织物表现出最好的凉感效果,经过凉感印花后织物的最大瞬态热流密度、凉感持续时间和凉感时段总散热量均得到了一定程度的提升;随着温度的升高,织物的最大瞬态热流密度值从254.6W/m^(2)下降到98.8W/m^(2),稳态热流密度值从99.6W/m^(2)下降到27.8W/m^(2);随着风速的增加,织物的最大瞬态热流密度从243.6W/m^(2)增加到275.9W/m^(2),稳态热流密度值从98.5W/m^(2)增加到231.6W/m^(2);随着水分含量的增加,织物的最大瞬态热流密度值从246.9W/m^(2)增加到376.6W/m^(2),并且到达最终热平衡的时间也从318s增加到2200s;主观排序值与最大瞬态热流密度、凉感持续时间和凉感时段总传热量进行拟合的相关系数分别为0.977、0.748和0.719,说明主观评价指标与客观指标有较好的一致性。
This study adopted the HFB-1 fabric cool feeling tester to objectively test the cool feeling of 12 printed fabrics.Besides,we investigated the influence of temperature,air velocity,and moisture content on fabric cool feeling.Additionally,a rank-order method was employed for a subjective assessment of fabric coolness.The results indicate that the nylon fabric demonstrats the best cooling effect.Furthermore,the maximum transient heat flux,the duration of cool feeling and the total heat dissipation during the cooling period of the fabrics were enhanced to a certain extent after the cool-felling prints.As the temperature increased,the fabric experienced a decrease in maximum transient heat flux from 254.6 W/m^(2) to 98.8 W/m^(2),and steady-state heat flux declined from 99.6 W/m^(2) to 27.8 W/m^(2).Simultaneously,with an increase in wind speed,the fabrics maximum transient heat flux rose from 243.6 W/m^(2) to 275.9 W/m^(2),and the steady-state heat flux increased from 98.5 W/m^(2) to 231.6 W/m^(2).Moreover,as moisture content increased,the fabrics maximum transient heat flux increased from 246.9 W/m^(2) to 376.6 W/m^(2),and the time to reach final thermal equilibrium extended from 318 s to 2200 s.The correlation coefficients for fitting subjective ranking values against maximum transient heat flux density,duration of cool feeling,and total heat dissipation during the cooling period were 0.977,0.748,and 0.719,respectively.These values indicated a strong consistency between subjective assessment metrics and objective indicators.
