摘要
在高倍显微镜下观察液态水沿纱线芯吸时的传递路径,分别建立液态水在纱线中轴向和径向传递的孔隙模型。通过分析得到：纱线芯吸时内部液态水的传递速率不同,中心传递速率大于周边传递速率。液体水沿纱线轴向传递时,水从纱线中心到纱线边缘所形成的毛细管尺寸逐渐变大。纱线芯吸有色液体平衡后,有色颗粒还会继续向上运动,但是不会超过已经形成的平衡界面,且随着有色颗粒的增加,有色界面颜色加深。液体水沿纱线径向传递,轴心孔隙较小首先被液体充满,中间孔隙与边缘孔隙之间形成类似U型的管道,促使轴心孔隙内的液体向边缘流动。
The transmission path of liquid water wicking along the yarn is observed under high magnification microscope, and the axial and radial pore models of liquid water passing through the yam are established respectively. The analysis shows that the transfer rate of liquid water inside the yarn is different when the liquid water wicks along the yam, and the center speed is faster than the peripheral speed. When the liquid water passes along the axial direction of the yarn, the size of the capillary forms by the water from the center of the yarn to the edge of the yarn gradually becomes larger. After the yarn wicks a colored liquid balance, the colored particles would continue to move upward, but would not exceed the equilibrium interface which has been formed, and with the increase of colored particles, the color of the colored interface deepened. The liquid water is transmitted along the yarn warp. The small axial pore is first filled with liquid. The U-shaped pipe between the central pore and the edge pore promotes the liquid in the axial pore to flow to the edge.
