Method of treating fibers with a cationic fiber lubricant which comprises:

• a) pre-reacting one or more polyamine-containing polymers having one or more free amine groups and one or more fatty acids moieties in an effective amount for at least water dispersibility and amine reactable organoalkoxy silane selected from the group consisting of the organoalkoxysilane and hydrolysis products thereof to yield the cationic lubricating reaction product with hydrolyzed or hydrolyzable organosilanes;
• b) formulating the pre-reacted material with at least water in a predominant amount into a chemical treating composition;
• c) applying the formulated composition to the fibers;
• and
• d) gathering the fibers into at least one bundle of fibers.
