不同芯吸材料吸水性能测试与拟合分析
Measurement and Fitting Analysis of Water Absorption Performance of Different Wick Absorbing Materials
【摘要】 首先设计制作了毛细吸水测试装置,实测了9种成分组成的布料毛细吸水高度变化,对比分析了组成成分对吸水快慢及最大吸水高度的影响;然后利用实测数据进行拟合,用统一模型回归,得到吸水高度的最佳拟合公式。结论表明:(1)聚酯纤维材料中加入氨纶成分可提高材料的毛细吸水速率,加入棉纤维则可进一步改善吸水效果;棉纤维含量高、竖向平整的材料有利于提高吸水高度;(2)条绒和速干布的吸水高度最大,为200 mm左右;(3)可利用指数模型拟合材料吸水高度变化,拟合优度均大于0.96;(4)指数模型可用于推测材料最终吸水高度,计算吸水上升速度,为实际应用提供参考。
【Abstract】 The capillary water absorption measurement device was designed and manufactured, and the variation of the capillary water absorption height of cloth composed of nine components was measured, and the influence of composition on the speed of water absorption and the maximum water absorption height was compared and analyzed. Then, the best fitting formula of water absorption height is obtained by using the measured data and the unified model regression. The results show that:(1) Adding spandex can improve the capillary water absorption speed of polyester fiber, and adding cotton fiber can further improve the water absorption effect. The material with high cotton fiber content and vertical leveling is beneficial to improve the water absorption height.(2) The highest water absorption height of lint and quick-drying cloth is about 200 mm.(3) The exponential model can be used to fit the variation of water absorption height of materials, and the goodness of fit is greater than 0.96.(4) The exponential model can be used to predict the final height of water absorption and calculate the rising speed of water absorption, which can provide reference for practical application.
