to the desired temperature and the coating applied the temperature at which the coating is applied is dependent upon numerous factors including cooling rate dilution and vaporization rate of the solvent containing the coating reactivity rate between the particular fiber and particular coating materials and atmosphere in the cooling chamber preferably the temperature of the fiber after the coating has been applied and solvent evaporated is in excess of 275 u00b0 f the maximum temperature of application is preferably less than the decomposition temperature for any of the components used in the coating but typically the finished temperature of the coated fiber should not exceed 525 u00b0 f the coating of the present invention comprises a mixture of a hydrolyzable silane or titanate coupling agent and an ionic surfactant suitable surfactants for example include carboxy acids sulfuric esters alkane sulfonates alkyl aromatic sulfonates and others specific examples include sodium oleate sodium lauryl sulfate and polyethylene glycol alkyl aryl ether the surfactant used is preferably dispersible in water and aids or enhances the ability of the fiber to be dispersed and also improves handling properties of the dry fiber the coupling agents used in the present invention are silanes titanates or mixtures thereof suitable silanes for example include hydrolyzable allyl amino alkyl beta chloropropyl epoxy mercapto methacrylato phenyl thioalkyl thio alkaryl and vinyl silanes their hydrolysis.
