Abstract
An aqueous spin finish, a process for treating polyamide yarn therewith and polyamide yarn so treated are all disclosed. The oil portion of the spin finish comprises a glyceride, ethoxylated oleyl alcohol, ethoxylated nonyl phenol, ethoxylated castor oil, an oxidized polyethylene, a non-nitrogen nonionic emulsifier for the oxidized polyethylene, and an alkali hydroxide. The spin finish has a pH of about 7 to 12. The spin finish has improved thermal stability which results in lower emissions during treatment of tire cord formed from polyamide yarn treated with the spin finish. Cord to rubber adhesion is also improved.
