It is necessary to study the suitable effect of plasma parameters, such as exposure time and applied voltage on the wicking properties of silk fabrics. Wicking property of silk fabric has been improved by using air dielectric barrier discharge plasma treatment. The plasma treatment has been utilized to modify the surface properties of silk fabrics. Untreated and plasma-treated fabrics have been characterized by contact angle Goniometer, wicking test, Wet-out time, scanning electron microscope, Attenuated Total Reflection Fourier Transforms Infrared spectrometer (ATR-FTIR) and dye uptake test. The ATR-FTIR characterization shows that the hydroxyl functional group has been increased after plasma treatment of silk fabric. The experimental results of wicking rate and Wet-out time of the plasma-treated silk fabrics have shown significant improvement in hydrophilic properties that could be confirmed by contact angle measurement which is close to 0°. The tensile strength of untreated and plasma-treated fabrics has been measured to confirm the enhanced surface property. 相似文献

以正硅酸乙酯和钛酸四正丁酯为前驱体合成SiO2/TiO2复合溶胶,用于棉织物涂层处理以制备UV光开关可控亲水-疏水功能棉织物。SiO2/TiO2复合溶胶涂层功能棉织物水接触角为121.3°,织物呈现疏水性,经UV光照射18h后,其接触角减小到0°,织物呈现亲水性。而UV照射后的织物放置暗处12h,其接触角由0°又增大到了93.2°,接触角得到恢复。织物再经UV光照射和放置暗处反复10次后,织物接触角仍然在0°和92°-96°之间转换,实现了织物亲水-疏水的可逆转换。经紫外光谱分析可知,SiO2/TiO2复合溶胶涂层功能织物经UV光照射后其紫外透过率会略减小,而放置暗处12h后,其紫外透过率又略微增强,这种变化从实验上验证了润湿性变化的机理。 相似文献

Many researches have been carried out to analyze the wicking behavior of the knitted fabric based on different principles. In this study, an investigation on wicking behavior of knitted fabrics under different deformation condition is attempted. An instrument has been designed and developed to measure the wicking rate of the fabric based on the principle of image processing technique under dynamic states with respect to time by simulating different movements. This instrument has been aimed to quantify the rate of wicking under different deformations in required time intervals and also the pattern of wicking area on both sides of fabric simultaneously. The statistical result shows that wicking in fabric under dynamic condition has been increased significantly on the knitted fabrics than the static condition. The comparative study of wicking trend at the front and back has been carried out and shows that the area of wicking is higher in front than back side of the fabric at any given period of time. The result shows that wicking in fabric under dynamic condition has been increased significantly on all the knitted fabric. The developed novel instrument could be utilized to carry out the study of the wicking behavior of any kind of fabrics matching to the real situation with higher accuracy and precision. 相似文献

Clothing plays an important role in maintaining thermal equilibrium between a human body and the ambient environment by serving as a medium for heat, moisture vapour and liquid moisture transfer. The ability of fabric to maintain this equilibrium is related to thermo-physiological comfort. Plating is an innovative knitted fabric production technique to obtain bi-layered fabrics. An attempt has been made to engineer plated knit structures with such a combination of fibre cross section in the back (inner/next to skin) and the yarn type in the face (outer) layer, so that a rapid liquid transfer from back layer by wicking and quick liquid absorption and evaporation by the face layer can be achieved. Plated fabrics using the combination of triangular polyester fibre in the back and carded cotton yarn in the face layer showed the higher thermal resistance, higher absorbent capacity and would be warmer to the initial touch. However, the combination of combed cotton yarn with triangular polyester fibre resulted in fabrics with the higher air permeability, moisture vapour transmission rate and transplanar wicking. 相似文献

为寻求更为环保的方式对羊毛/羊绒车饰品进行疏水整理,利用射频低温等离子体协同静电喷雾技术对织物进行疏水整理。通过扫描电镜观察了织物原样、等离子体处理织物、静电喷雾疏水织物和等离子体处理后静电喷雾疏水织物4种样品的表面形貌变化,采用动态接触角测量仪测试了4种样品的黏附力、静态接触角和动态接触角。结果表明:由于等离子体处理对织物表面的刻蚀作用,使后续选用静电喷雾整理的疏水剂能更有效且均匀地吸附于纤维表面;等离子体处理使织物表面黏附力提高至98.39μN,静态接触角减小至107.9°,接触角滞后增加至83.39°;等离子体处理协同静电喷雾疏水整理的织物具有最低的黏附力及接触角滞后,且织物透气率和透湿率仅分别下降了2.9mm/s和384g/(m2·d),说明等离子体表面改性协同静电喷雾疏水整理具有可行性。 相似文献
