异形涤纶织物吸湿等温线的研究与模拟

Research and simulations of moisture absorption isotherms of profiled polyester fabric

选用相同组织结构的异形涤纶(三叶形)织物和普通涤纶织物,测定它们在不同温度、不同相对湿度下的吸湿等温曲线,归纳出温度、相对湿度、材质对织物吸湿性的影响规律,并用多分子层吸附模型对实验数据进行了拟合.结果表明:在相同环境条件下,异性涤纶的吸湿性优于普通涤纶;随着温度的升高,2种织物的平衡含水率略有下降;随着相对湿度的增大,2种织物的平衡含水率增大,且相对湿度比温度有更大的影响作用;多分子层吸附模型能较好的与实验数据相吻合.

The moisture absorption isotherms were measured at different temperature and different relative humidity of the profiled polyester（trefoil-shaped） fabric and common polyester with the same textures,the effects of the temperature,relative humidity and fibre material were summarized on the moisture absorption properties of fabrics,and the molecular layer adsorption model was used to fit the experimental data.The results showed that under the same environmental conditions,the profiled polyester moisture absorption was better than the common polyester;the equilibrium moisture of two fabrics was declined slightly with the increase of temperature;the equilibrium moisture of two fabrics was increased with the increase of the relative humidity,and the influence of relative humidity was better than the temperature;multi-molecular layer adsorption models coincided well with the experimental data.
