摘要
选择几种不同组织结构的试样,探讨了织物结构参数,如厚度、平均浮长、覆盖系数对织物热传递性能的影响,利用相关性分析的方法,得到织物热传递性能随织物结构参数变化的规律。结果证明:织物厚度的增加,会使织物的克罗值增大,但是增大的幅度在减小,增大到一定程度后有减少的趋势;平均浮长愈长,织物的克罗值愈大,但增大的幅度逐渐减小,平均浮长过大,克罗值反而减少;随着覆盖系数的增大,织物的克罗值随之减小,织物的热传递性能随之增加;随着覆盖系数的减小,织物的克罗值相应增大,热传递性能随之减小。
The influences of structure parameters such as thickness, average float, and cover factor on the heat transfer of the fabric were investigated. By means of correlation analysis, the rule of the heat transfer varying with fabric structure parameters was attained. The CLO value of the fabric increases with fabric thickness, but when reaching to a certain extent, its increase margin drops. The larger the average float, the greater the CLO value, its increase margin also drops. However, instead of increasing the CLO value, too large an average float makes CLO value downwards. Increasing fabric cover decreases the CLO value, but increases the heat transfer. Contrarily, decreasing fabric cover factor increases the CLO value, but decreases the heat transfer accordingly.
