摘要
通过对红外分光光谱法、洗涤减量法及核磁共振法3种涤纶工业长丝含油率测试方法的比较,找出这3种方法之间的不同及相互联系,认为核磁共振法具有测试速度快、操作简单、测试精度高及不需试剂的优点。
The oil content of PET industry yarn was determined by the three methods of infrared spectrophotometry, washing with neutral soap and nuclear magnetic resonance spectroscopy. These three kinds of test methods were compared. The results showed that they were difference and intercoordination and nuclear magnetic resonance spectroscopy method was featured by rapid test, simple operation, high accuracy and without reagent.
