  • Publication number: 20080282483
    Abstract: Solute-loaded polymer microparticles are obtained by immersing microparticles in a bath comprising a selected solute dissolved in a ternary solvent system. A first solvent of the ternary system is a strong solvent for both the solute and the polymer from which the microparticle was formed. A second solvent is a weak solvent or non-solvent for the solute and the polymer (tuning solvent). A third solvent is a weak solvent or non-solvent for the solute and polymer, but serves as a co-solvent with respect to the first and second solvents in that it is miscible with both the first and second solvents. The amount of solute incorporated into the microparticles is controlled by adjusting the ratio of solute with respect to the microparticle polymer, and by adjusting the composition of the ternary solvent system, principally the amount of tuning solvent.

  • Patent number: 6039767
    Abstract: An improved method of dyeing a polyolefin material, and preferably a polypropylene based fiber, involves a disperse dye mix including a selected plurality of disperse dyes from the same primary color group. Each dye within the mix and the concentration of each dye within the mix is selected by testing individual disperse dye solutions with an undyed sample and determining the maximum dye concentration which will produce an acceptable crocking test for that dye. A plurality of disperse dyes within the mix are each at a concentration of at least 75% of the maximum dye concentration for that individual dye. The selected dye mix is used to prepare a disperse dye mix solution which is then contacted with the polyolefin material to reliably dye the material without fastness problems. A red dye mix, a blue dye mix, and the yellow dye mix may each be prepared and may each be separately used to dye polypropylene fibers with relatively dark shade without crocking problems.

  • Patent number: 4802886
    Abstract: A continuous process for the dyeing of melt-extrudable polymers that are capable of being dyed, is disclosed. The process comprises extruding molten polymer through an orifice, contacting the extruded polymer while still in a molten state with an aqueous solution of a dye for said polymer, and withdrawing the resultant dyed polymer from the aqueous solution. The process may be used for the dyeing of e.g. modified polyolefins, polyamides, ionomers and the like. In preferred embodiments the process may be used in the extrusion coating of wire or other continuous filamentary material to provide color-coded products.

  • Patent number: 4732571
    Abstract: A process for the dyeing of polymers of ethylene is disclosed. The process involves contacting articles of the polymer with an aqueous dyebath containing a basic dye in a concentration of at least 0.5 g/l and at a pH of at least 5.0. The temperature of the aqueous dyebath is at least 35.degree. C., especially at least 55.degree. C. The article is maintained in contact with the dyebath for at least 20 seconds. The polymer of ethylene is a blend of 65-99 parts of a homopolymer of ethylene or copolymer of ethylene and at least one C.sub.3 -C.sub.10 higher alpha-olefin with 1-35 parts of a direct or graft copolymer of an alpha-olefin having carboxylic acid, carboxylic acid anhydride, ionomeric or --OH groups. Dyed polymers of ethylene are obtained.
