Abstract

The use of super absorbent polymers (SAP) for moisture absorption and comfort is still unexplored. The aim of this work was to observe the application of super absorbent fibres in car seats for comfort purposes. In this research the efficiency of different SAP fibrous webs were determined under different moisture percentages to examine the sorption and desorption efficiency. A SAP fibrous web with low thickness and high moisture absorption were tested with a multilayer sandwich structure of a car seat cover to determine moisture absorption through the cover material. The standard Cup method was used to determine the moisture permeability of different car seat covers with a superabsorbent layer closed with impermeable polyurethane foam. It was observed that the SAP fibrous layers are very effective in absorbing and desorbing water vapour under extremely high and low moisture percentages. In extreme humid conditions (95%RH), 20g of the SAP layer absorbs nearly 70% of its weight in water vapour, reaching the maximum absorption capacity in 6 hours.

高吸水性材料对提高汽车座椅热舒适性的作用

使用高吸水性聚合物(SAP)的吸湿性和舒适性仍未被探索。本研究的目的是观察高吸水性纤维在汽车座椅中的舒适性应用。在不同含水率下，测定了不同SAP纤维网的吸附和解吸效率。以一种低厚度高吸湿性的SAP纤维网为材料，对多层夹心结构的汽车座套进行了吸湿性测试。采用标准杯法测定了不同的汽车座套的透湿性，这些座套采用不透水的聚氨酯泡沫封闭的高吸水性层。结果表明，在极高和极低的含水率下，SAP纤维层对水蒸气的吸收和解吸都非常有效。在极端潮湿条件下(95%相对湿度)，20g的SAP层吸收了其重量的近70%的水蒸气，在6小时内达到最大吸收能力。
