PROCESS FOR PRODUCING ADHESIVE ACTIVE POLYESTER YARN

摘要

PROCESS FOR PRODUCING ADHESIVE ACTIVE POLYESTER YARN An improvement is provided in a process for the production of polyester yarn involving spinning and drawing steps. The improvement comprises exposing the yarn subsequent to the drawing step to ultraviolet radiation, and treating the yarn with a finish composition which comprises water and a silane having the structural formula wherein n = 2 to 5. The yarn is preferably used in tire cords for the construction of pneumatic passenger tires and results in excellent adhesion of tire cord to rubber.
