Wicking and Drying Behavior of Knitted Cotton Fabrics under Modified Water Drop Test

ABSTRACT

Both face and back sides of cotton weft-knitted fabrics in five knitting structures (plain, rib, interlock, single pique, and double pique) were investigated based on modified water drop test (methods I and II) in terms of water diffusion time. The water drop height was raised from 1 cm to 20 cm and water drop volume was increase from 0.1 mL to 0.5 mL. The water diffusion time greatly decreased with the variation in water drop height from 0 to 15 cm. Water diffusion time was also influenced by water volume at 0.1–0.2 mL for the different structures and surfaces. It was found that the structures behaved differently, and two surfaces of fabric were capable of asymmetric water absorption property. The face side of single pique and the back side  double pique had better water diffusion property. Besides, vertical wicking rate and the drying rate (methods I and II) were also conducted to evaluate the different structures. Although the plain structure was widely used for inner garments in the market, the interlock fabric was recommended in nonsweating conditions due to its poor water spreading and better drying ability, while the single-pique fabric was recommended in heavy sweating conditions due to its better water absorption ratio and faster drying rate.

摘要

基于改进的水滴试验（方法一和方法二）水扩散时间项，研究了五种针织结构（平纹、罗纹、双罗纹、单珠地网眼和双珠地网眼）棉纬编针织物的正面和反面. 测试的水滴高度从 1 厘米到 20 厘米不等，水滴体积从 0.1 毫升到 0.5 毫升不等. 当水滴高度在 0～15cm 范围内变化时，扩散时间明显缩短. 对于不同的结构和表面，当水体积在 0.1-0.2ml 时，水滴体积影响水的扩散时间. 结果表明，织物的结构表现不同，两种表面具有不对称的吸水性能. 单珠地网眼的正面和双珠地网眼的背面具有较好的水扩散性能. 此外，还进行了垂直吸芯速率和干燥速率（方法一和方法二）来评估不同的结构. 虽然平纹织物在市场上广泛应用于内衣裤，但由于平纹织物的水分散开性差，干燥性能好，推荐在非出汗状态下使用，而单珠地网眼织物由于吸水率高，干燥速度快，推荐在重出汗状态下使用关键词:水扩散,正面和反面,不对称,芯吸,干燥
