TITLE CONTINUOUS PRODUCTION OF POLYESTER FILAMENTS ABSTRACT When varied spin-oriented polyester filaments are produced over the course of time in a continuous multi-machine operation from polymeric precursors, the dyeabilities of the varying products are controlled and adjusted by adding small amounts of a chain-branching agent, such as a derivative of trimellitic acid, preferably trishydroxyethyl trimellitate. The process conveniently lends itself to automation of the control and adjustment operation. I.9 DP-4440
