Pattern printed fabric with directional water transport,highly breathable and moisture-permeable properties

针对传统单向导湿织物层间结合力差和制备工艺复杂的问题,利用丝网图案印刷技术,在针织物表面构筑了均匀分布的亲水孔道,从而实现了高透气透湿性能单向导湿织物的可控制备。使用扫描电子显微镜、X射线能谱仪、傅里叶变换红外光谱仪、接触角测试仪、透湿仪、透气仪和液态水分管理仪分析了织物的微观形貌、元素分布、化学结构、亲水性和穿着舒适性能,并对印花工艺进行优化。结果表明:在90%疏水面积、30 Hz印花压力下,可制备理想的图案印花织物,透气率为104 mm/s,透湿量为289 g·m^(-2)·h^(-1),单向导湿指数为588%,具有良好的应用前景。

Addressing the issues of poor interlaminar adhesion and complicated preparation process in traditional unidirectional water transport fabric,hydrophilic channels were successfully constructed on the surface of the knitted fabric by pattern screen printed technology,resulting in a directional water transport fabric with high air permeability and moisture permeability.Herein,scanning electron microscopy,X-ray spectroscopy,Fourier infrared spectrometer,contact angle tester,moisture permeability meter,air permeability meter,and moisture management meter were used to analyze the morphology,element distribution,chemical structure,hydrophilicity,and wearing comfort properties of fabric.Besides,the printing process was optimized to improve the properties of the fabric.The results show that the ideal pattern printed fabric with a 90% hydrophobic area was successfully prepared under the printing pressure of 30 Hz.The resulting fabric exhibited an air permeability of 104 mm/s,a water vapor transmission of 289 g·m^(-2)·h^(-1),and a one-way transport capability of 588%,making it suitable for a variety of applications.
