Preparation of Spin Finishes for Polypropylene Fibers and Nonwoven Fabrics for Hygienic Applications
E-mail:
Spin finishes for PP (polypropylene) fibers and nonwoven fabrics were prepared with various compositions of lubricant, surfactant, antistat, and other components. The best formulation for the spin finish was investigated; we found that a high MW lubricant and a low MW surfactant affected the hydrophilic properties of the spin finish. Strikethrough, sinking time, and run-off tests indicated that the spin finishes prepared in this study had excellent hydrophilic properties and the capability of being applied both on PP fibers and nonwoven fabrics. We also found that OPU (oil pickup) affected the strikethrough of the spin finishes.
