通过毛细管力液体自发输送到多孔体系被称为芯吸。毛细管力由吸湿产生,芯吸是毛细体系中自发吸湿的结果,吸湿是芯吸的前提,液体不能湿润纤维的话,就不能芯吸进入织物。芯吸仅仅发生在纤维通过液体吸湿后,纤维之间的毛细空间中,毛细管力驱使液体进入毛细空间。
Spontaneous delivery to a porous system by a capillary force liquid is called wicking. Capillary force is generated by moisture absorption. Wicking is the result of spontaneous moisture absorption in the capillary system. Moisture absorption is the prerequisite for wicking. If the liquid can not wet the fiber, it can not be wicked into the fabric. Wicking occurs only in the capillary space between the fibers after the fibers have absorbed moisture through the liquid and capillary forces force the liquid into the capillary space.
