针织物间液体传导的机理研究

Transfer Wicking of Knitted Fabrics from Layer to Layer

外部压力对液体在织物间传导有很大的影响 ,较高的压力能触发液体在织物间传导的发生。至于外部压力对织物间液体传导速度的影响 ,则存在一个压力最佳值 ,在最佳压力值下 ,织物间液体的传导最快。湿层织物初始含水量高则明显地增加了织物间液体的传导量。由于单面毛绒织物的两面具有不同的毛细管尺寸 ,当干层织物的光面与湿层织物的光面和毛面分别接触时 ,液体在织物间发生转移 ,传导量前者大于后者 ;当干层织物的毛面与湿层织物的光面和毛面分别接触时 ,织物间没有液体转移现象发生。

This study was an investigation regarding liquid transfer from fabric layer to layer. The external pressure had a significant effect on liquid transfer from fabric layer to layer. A higher external pressure led to an early onset of transfer wicking. There existed an optimum value of pressure for the maximum of water transfer. For the fleece fabrics, no significant transfer wicking occurred if the raised side of the dry layer contacted either side of a wet fleece fabric layer. If the smooth side of the dry layer contacted either side of the wet fleece fabric layer, the amount of water transferred from layer to layer was greater when the fabric setting was face to face than face to back. This is attributed to higher capillary pressure.
