Measuement of Apparent Contact Angle in Yarn Using Microscope

광학 현미경을 이용한 실에서의 접촉각 측정

Authors measured the apparent contact angle in a yarn using microscope because it gives a useful information in the evaluation of comfort factors in fabrics. The mechanical stage of microscope was designed and built to facilitate this measurement. Variables examined were the fiber type, the twisting number, and the fluid type. All produced significant effect most of which could be rationalized based on the known concepts. The methodology used and the results obtained are discussed in detail.
