高強力聚酯纖維織物經電子束處理後，利用連續性的影像處理系統，將擷取液體滴在高強力聚酯纖維織物上的畫面，籍由甘油、polyquaternium-7與高強力聚酯纖維織物表面間的角度變化，將量測到的接觸角代入Owens and Wendt公式中，即可推算出表面能。
The fabric of high density PET after electron beam treatment, and observed the contact angle of glycerol and polyquaternium-7 for fabric of high density PET. With CCD camera imaged system. Then measured the contact angle into Owens and Wendt equation, and got surface energy.
