  • Polymeric materials
    Patent number: 11124896
    Abstract: Additives such as colourants may be incorporated into polymeric materials such as polyesters, such as in polyester fibre production, by use of a liquid formulation comprising colourant and a vehicle. The vehicle may comprise a functionalised pentaerythritol, trimethylolpropane or trimellitate. The liquid formulation is suitably contacted with the polymeric material in a melt processing apparatus.
    Type: Grant
    Filed: February 22, 2017
    Date of Patent: September 21, 2021
    Assignee: COLORMATRIX HOLDINGS, INC.
    Inventors: Chun Lew, Phillip Winrow, Andrew Overend, John Goulbourn
  • Polymeric materials
    Patent number: 10053545
    Abstract: A method of introducing an additive into a polymeric material comprises using a liquid formulation comprising an additive, for example a colorant, and a vehicle comprising an aliphatic or aromatic tri- or di-carboxylic acid covalently linked by ester bonds to two or more chains. The method involves contacting the liquid formulation with the polymeric material in a melt processing apparatus. The cavity transfer mixer may be used in the process. A fiber is suitably subsequently produced.

  • Method of introducing an additive into a polymeric materials
    Patent number: 9611365
    Abstract: Additives such as colorants may be incorporated into polymeric materials such as polyesters, such as in polyester fiber production, by use of a liquid formulation comprising colorant and a vehicle. The vehicle may comprise a functionalized pentaerythritol, trimethylolpropane or trimellitate. The liquid formulation is suitably contacted with the polymeric material in a melt processing apparatus.

  • Polymeric materials
    Patent number: 9139704
    Abstract: A method of introducing an additive, for example a dye, into a polymeric material comprises using a liquid formulation comprising the additive, a vehicle and an active compound added to increase the melt viscosity of the polymeric material. The active compound may be a multi-functional anhydride. The liquid formulation is suitably contacted with the polymeric material in a melt processing apparatus and suitably a cavity transfer mixer is used in the process. A fiber is suitably subsequently produced.
