动态毛吸法测定纤维表面能

STUDIES ON SURFACE ENERGETICS OF KEVLAR-49 BY WICKING TEST

摘要: 本文用浸润测定仪对玻璃纤维和Kevlar-49芳纶纤维进行了表面能测定,讨论了纤维束柱末端沾湿量的影响,提出了浸润仪测试数据的正确处理方法,求得了Kevlar-49纤维的表面能并对其色散分量和非色散分量进行了解析.

Abstract: The surface energetics of Kevlar-49 and glass fiber were studied by wicking test.The affecting of liquid quantity adhering on thebundle end was discussed. A data treatment method was proposed as well. The surface free energy of Kevlar-49 was determined as 37 mJ/m²,with the dispersive component of 28 mJ/m² and the polo:component of 9 mJ/m².
