Abstract
A high solids spin finish composition is provided that can be readily applied to synthetic fibers during the fiber-making process. The spin finish composition comprises a hydrocarbon surfactant and a fluorochemical emulsion.
Claims9
A method for making a spin finish composition, comprising the steps of:
- providing a hydrocarbon surfactant;
- providing a fluorochemical emulsion;
- and
- mixing together the hydrocarbon surfactant and the fluorochemical emulsion such that the resulting composition has at least about 70% solids and a <HLB> value within the range of about 2 to 13.
