磁控溅射镀铜芳纶织物的制备及其性能研究

芳纶纤维具有优异的力学性能和加工性能,还具有极好的耐热和耐化学药品性能、尺寸稳定性、耐疲劳性及耐腐蚀性等。磁控溅射镀膜法是一种高效的薄膜沉积工艺,具有装置性能稳定、操作控制方便、无环境污染等优势。采用磁控溅射法在芳纶织物表面镀覆纳米铜薄膜,使纺织品表面金属化。镀铜芳纶织物采用XRD与扫描电镜进行表征,且评价镀铜织物的抗静电性、导电性及拒水性。结果表明,溅射镀膜50 min的镀铜纤维表面致密地沉积纳米铜;XRD图显示铜的结晶存在。溅射镀膜50 min的镀铜芳纶织物接触角高达132.5°,表面电阻为129Ω/sq,抗静电半衰期为0.4 s。表明其具有良好的拒水、导电及抗静电性。     

Influence of Clothing Fabrics on Skin Microcirculation

This study investigated the effects of clothing fabric on human skin microcirculation.Once skin is covered with a clothing fabric,human sensations,namely,coolness,warmth,softness,and roughness,are aroused immediately,and the cutaneous microcirculation may be changed consequently.Since the complex relationships of the human skin,the environment,and the clothing,there is few publication focusing on the physiological responses of the skin to the fabrics.In this paper,a Laser Doppler Flowmetry(LDF)was used to t...     

Wet Permeability and Moisture Vapor Transmission Characteristics of Soybean Knitted Fabrics

Wet permeability of fibrous assembly is mainly influenced by the properties of liquid and the configurations of the fiber which consist of diameter of fiber, twist angle and fiber alignment in a yarn. It can be seen from experimental results that the knitted fabric made of soybean (SB) fiber has good properties both in wet permeability and vapor transmission so that the knitting technology and fabric characteristics can be improved.

Study on Wet Permeability Models of Yarns and Knitted Fabrics

Water transport through the pore structure of the knitted fabric can occur only in place where the fiber-water surface attraction force is greater than the water weight in the capillary. To investigate wet permeability of the knitted yarn in the fabric, a liquid transport model is established. The main factors which have significant influences on the liquid transport have been analyzed. It is derived from the argument that the optimal design for the knitted fabric with quick sweat transport property can be obtained.
