针对5种棉针织物,分别测试其纱线线密度、横密、纵密、线圈长度、未充满系数、克质量、厚度等基本性能,以及克罗值、透气量、透湿率、芯吸高度等热湿舒适性能,并对所测试的数据利用SPSS因子分析的方法,探讨棉针织物基本性能与热湿舒适性能的关系。结果表明:由相关性分析获得的纱线线密度、克质量、厚度这3个因素对棉针织物的热湿舒适性影响比较大,在实际生产中可通过对这3个指标的设计与测定来预测或改变产品的热湿舒适性能。 相似文献

采用KES-F7织物热性能测试仪、YG141D数字式织物厚度测试仪及锡莱热阻湿阻测试仪,在常温下测量不同含量、不同组织的PTT纤维的热传导性能、热阻湿阻性、织物厚度及透气性.结果表明,PTT网眼织物的舒适性明显优于其他几种纬编针织物,相对于其他纬编针织物组织不仅具有良好的导热率、优良的透气性,而且瞬间冷暖值也相对较小,织物的舒适性好. 相似文献

为比较不同组织结构的织物在含湿状态下的热舒适性能,用KES织物风格仪测试了在一定含湿状态下涤纶针织物、机织物的热舒适性能。结果表明:织物含水率越高,瞬间冷感越强,热传导性能提高,保暖性能下降;在含湿率相同的状态下,涤纶机织物比针织物瞬间冷感更强;编织方法对导热系数随含湿率变化的规律没影响;涤纶机织物、针织物在纯干燥状态下的保暖性相差无几,但加湿后2种织物保暖性能差别显著。通过综合分析比较,认为涤纶针织物保暖性好于涤纶机织物。 相似文献

为研究织物结构参数对聚乙烯针织物热湿舒适性能的影响,选取3种规格的聚乙烯长丝织成双罗纹针织物,并选用涤纶、凉感涤纶长丝制备相同结构双罗纹织物作为对比试样,研究构成织物的原料种类、未充满系数、捻度对织物孔隙率、透气性、导热及导湿性能的影响。结果表明:在织物结构相同的情况下,构成织物的原料、未充满系数与织物透气、导湿、导热等热湿舒适性能显著相关;纱线捻度与织物的导热及导湿性能显著相关;与涤纶、凉感涤纶织物相比,聚乙烯长丝表面存在沟壑,结晶度、取向度较高,其织物具有优良的透气、导湿和导热性能,是制备凉爽舒适功能纺织品良好原材料。 相似文献

The thermo-physiological comfort and compression properties of knitted spacer fabrics have been evaluated by varying the different spacer fabric parameters. Air permeability and water vapor transmission of the fabrics were measured using the Textest FX-3300 air permeability tester and PERMETEST. Thermal behavior of fabrics was evaluated by (TCi) thermal conductivity analyzer and overall moisture management capacity was evaluated by moisture management tester. Spacer fabrics compression properties were also tested using KES-FB3. In the KES testing, the compression resilience, work of compression, linearity of compression, and other parameters were calculated from the pressure–thickness curves. Analysis of variance was performed using new statistical software named QC expert trylobite and Darwin in order to compare the influence of different fabric parameters on thermo-physiological and compression behavior of samples. This study established that the raw materials, type of spacer yarn, density, thickness, and tightness of surface layer have significant influence on both thermal conductivity and work of compression in spacer fabrics. The parameter which mainly influences the water vapor permeability of these fabrics is the property of raw material i.e. the wetting and wicking properties of fibers. The Pearson correlation between moisture capacity of the fabrics and water vapor permeability was found. 相似文献

选择8种不同的羊毛与普通涤纶、37.5涤纶混纺针织物试样,测试试样的密度、面密度、未充满系数和厚度等基本参数,以及回潮率、透气率、芯吸高度、瞬间接触凉感(Q-max)及恒定加热条件下的干、湿态升温性能等织物的热湿舒适性能,分析和评价了针织物的基本参数对其热湿舒适性能的影响。试验结果显示,与普通涤纶相比,采用37.5涤纶有助于提高织物的回潮率、芯吸高度和Q-max;透气率随针织物未充满系数的增大而增大;当织物的纤维组成成分基本一致,组织结构相同时,针织物的面密度越大,透气性越差;含37.5涤纶的纬平针织物的瞬间接触凉感性能较好。 相似文献

Double-face knitted fabrics with hydrophobic inner and hydrophilic outer layers are characterised by their advantageous thermo-physiological comfort property that facilitates the transport of sweat from skin to outer fabric layer where it can be evaporated easily. In this study, for the production of double-face knitted fabrics, cotton yarn as hydrophilic yarn type and five different polyester filament yarns consisting of standard polyester, hollow polyester, micro polyester, textured polyester and textured micro polyester as hydrophobic yarn type were used. In order to determine the thermo-physiological comfort properties of the fabrics, air permeability, water vapour permeability, thermal conductivity, thermal resistance and overall moisture management capacity were measured. The results were comparatively analysed using statistical methods. The experimental results demonstrated that the polyester-type yarns and the combinations of them with the cotton yarn in fabric layers affected the thermo-physiological comfort properties significantly. The fabrics with polyester-type inner face and cotton outer face showed the best moisture transmission properties. 相似文献

针对针织面料的凉爽性能评价没有明确系统的表征和检测方法的现状,提出了针织面料的凉爽性能的综合评价方法。以干态织物升温性能表征织物导热能力,以湿态织物升温性能表征织物导热、水分扩散和蒸发等降温性能;结合织物导热性能的评价原理,提出针织面料凉爽性能的评价指标:凉爽温度、凉爽温度指数和凉爽能力指数。采用相关性分析方法对34块织物的相关热湿舒适性能参数与凉爽性能参数的相关性进行分析,并基于逐步法多元回归分析建立了凉爽性能参数的预测模型。研究结果表明:与织物凉爽性能相关的主要因素包括织物的热阻、湿阻、干燥速率和扩散半径;凉爽能力指数可通过织物的热阻、湿阻和干燥速率进行预测,凉爽温度可通过织物的热阻和扩散半径进行预测。 相似文献
