Characterizing Spin Finish Layers on Polypropylene Fiber Surfaces by Means of Scanning Force Microscopy Techniques

摘要

For a better understanding of the structure, distribution, and composition of spin finish layers on fiber surfaces, scanning force microscopy techniques are used to image spin finish layers on polypropylene fiber surfaces with submicrometer resolution. The polypropylene staple fibers are made into nonwovens, and common antistatic, wetting, and hydrophobizing agents are the spin finishes. Distribution and thickness profiles of the wax-like antistatic and hydrophobizing agents are successfully measured with con- tact mode atomic force microscopy and lateral force microscopy.
