摘　　要：为提高人体睡眠热舒适性,改善睡眠质量,对不同参数的棉纱布被进行系统的保暖性能研究。借助出汗热平板纱布织物实验与出汗暖体假人被子实验,探究了棉纱布织物透气性、面密度、层数及水洗处理等因素对纱布被织物热阻的影响规律,并建立纱布被织物热阻与被子热阻的相关关系。结果表明:纱布被织物的热阻与其面密度呈明显的正相关线性关系,热阻与透气率相关性较低;棉被与纱布被的面密度相当的情况下,棉被的保暖性能更好,纱布被的透气性更好;纱布被织物的热阻与层数之间呈线性关系,层数越多热阻值越大;水洗处理后棉纱布被织物的热阻增加;纱布被织物热阻与纱布被子热阻呈显著的相关关系,当纱布被织物的总热阻较小(小于1.8 clo)时,二者近似呈线性关系。本文研究结果可为开发高质量棉纱布被提供参考。Objective Studies on thermal insulating properties of quilts have been carried out aiming to improve the thermal comfort and sleep quality.Previous studies mainly focused on quilts with filling materials,and few research focused on non-filling quilts such as gauze quilt.In order to provide more understanding on comfortable sleeping microclimate,a systematic investigation on thermal insulating properties of several gauze quilts with different parameters was conducted.Method 41 samples in total were provided,including 22 unwashed cotton gauze quilt fabric samples,4 washed cotton gauze quilt fabric samples,3 spunlaced cotton wadding samples,6 cotton gauze quilt samples.The influences of air permeability,surface density and number of layers on heat resistance of cotton gauze quilts were analyzed by sweating hot plate tests and thermal manikin tests.The correlation between heat resistance of fabric and quilt was also established.Results It was found that the heat resistance of both cotton gauze quilt samples and cotton spunlaced wadding samples have significant positive linear relationships with surface density.The heat resistance rose with the increase of surface density.The growth rate of the spunlaced cotton wadding quilts(0.0061)was higher than that of cotton gauze quilts(0.0017).Heat resistance of cotton gauze quilt samples decreased with the increasing of air permeability,exhibiting a low correlation,but the influence on thermal insulation was obvious when the air permeability was below 1000 mm/s.The heat resistance of the spunlaced cotton wadding quilt showed a significant negative linear relationship with its air permeability.In addition,the air permeability and surface density presented an exponentially negative correlation.The change rate was constantly decreasing when surface density was more than 450 g/m2.Generally,the air permeability of each cotton gauze quilt was above 500 mm/s,higher than that of the spunlaced cotton wadding quilt.The surface fitting results(thermal insulation as dependent variable,air
