  • Continuous production of polyester filaments
    Patent number: 4945151
    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.
