为了分析含湿率对针织面料热湿传递性能的影响,选取了市面上常用于制作运动服装的5种针织面料作为研究对象。测试不同含湿率下织物的热传导率、透气率以及透湿率,表征不同含湿率对织物的热湿传递性能的影响程度。结果表明:含湿率变化对针织运动面料的热传导率和透湿率具有显著的影响,对针织织物的透气率影响较小,织物的透气率主要受不同织物的组织结构影响较明显;涤棉混纺的针织织物,在织物含湿后,有利于增加织物的隔热保暖性能。 相似文献

为全面准确地评估湿态下消防服用多层织物系统的热防护性能,通过改进现有的热防护性能测试仪器,采用传统热防护性能实验与蓄积热实验2种方法,利用模拟人体皮肤传感器取代标准测试中的铜片热流传感器,基于Pennes热量传递方程,根据Henriques人体皮肤烧伤模型做出烧伤预测,并利用迭代法获得二度烧伤最少热暴露时间。分析了织物系统含水率对二度烧伤最少热暴露时间及热蓄积指数的影响。实验结果表明:2种实验方法测得的二度烧伤最少热暴露时间随含水率的增大明显降低,热蓄积指数也呈降低趋势;二度烧伤最少热暴露时间与含水率之间存在显著的线性负相关关系。 相似文献

磁性纤维含量是磁性面料表面磁场强度和面料成本的决定因素,也可能对面料的服用性能产生一定影响。本研究采用实验的方法对由磁性纤维和非磁性纤维按不同比例织造而成的常用针织磁性面料的服用性能进行研究,分别对面料的力学性能、抗起毛起球性、尺寸稳定性、透湿性等进行测试。研究表明:随着面料中磁性纤维含量的增加,面料的断裂强力和顶破强力减小,抗起毛起球性减弱,透湿性变差;而织物的弯曲性、悬垂性、尺寸稳定性无显著变化。本研究是磁保健服装研究的重要组成部分,能够为磁性面料在服装上更好的运用提供参考和借鉴。 相似文献

The transmission property of a fabric is a key factor that affects clothing’s comfort and decides the functional potential of clothing. The dependence of filament cross-section with varying shape factor (SF) on air, moisture and thermal transmission behaviour of fabric is determined in case of polyester multifilament woven fabrics. The linear density of each filament is kept identical for all 12 cross-section shape filaments. The SF of filament cross-section is an important factor which remained the prime factor to influence the transmission behaviour of fabric samples directly in many cases. Other indirect factors that influence the transmission behaviour of fabrics when the SF is identical are yarn structure, inter-fibre and inter-yarn space. Twelve different novel cross-sectional shapes are considered to make the multifilament woven polyester fabrics. The fabrics made from multifilament yarns having different SFs show that relative moisture vapour permeability and air permeability decrease with the rise in SF. Wickability increases with the rise in the SF of a filament cross-section. Multilobal, hexalobal and plus shapes were made a part of novel cross-sectional shapes in order to develop fabrics of higher comfort index. 相似文献

The thermal protection performance (TPP) provided by fabric assemblies used by wildland firefighters is greatly affected by both the moisture and the air gap trapped in multilayer fabrics. In this paper, the effect of moisture, coupled with air gap on TPP was analyzed under radiant heat exposures of 21 kW/m2. The air gap sizes from 0 to 5.2 mm were analyzed using an air gap height regulation device; the moisture content of the multilayer fabric combinations around 0–70% were obtained by spraying distilled water to simulate varying amounts of sweat absorption. The results obtained indicate that certain air gaps entrapped in multilayer fabric system have a positive effect on TPP for both dry and wet multilayer fabric combinations. However, obvious trend changes in thermal protection were observed among dry and wet configurations when the air gap was moved to different positions. For the wet configurations, the second-degree burn time increased as the air gap moved further from the heat source, which was contrary to burn time response under dry conditions. These findings suggest that the complicated reciprocal effect of air gap and moisture on thermal protection should be both considered in analyzing the TPP of fabric assemblies. 相似文献
