  • Patent number: 5955523
    Abstract: Disazo chromphores having at least two different poly(oxyalkylene) substituents are linked together by a covalent bond or by an intervening connecting group to form dimers. The preferred poly(oxyalkylene) substituents are straight chain polymers consisting of ethylene oxide and propylene oxide. The disazo colorants are useful for coloring thermoplastic resins such as polypropylene and polyethylene and show improved extraction, migration, clarity and thermal stability characteristics as compared to standard monoazo colorants.

  • Patent number: 5865933
    Abstract: An apparatus and method for creation of a textile fabric that has been patterned with a selective application of heat, which provides a carved portion in registry with a color change. The textile fabric includes a blend of fibers of a first polymer having a first color with fibers of a second polymer having fibers of a second color. The melting point of the first fibers exceeds that of the second fibers. When patterned with a selective application of heat that exceeds that of the second fibers but is less than that of the first fibers, the second fibers melt away leaving the first fibers with the first color dominating. In the uncarved areas, the resulting color is a blend of the first color and the second color.

  • Patent number: 5861044
    Abstract: An apparatus and method for selectively carving textile fabric by selectively applying chemicals containing a liquid repellent either alone or with other chemicals such as dye to a textile fabric and subsequently finishing said fabric. The textile fabric is then rewetted by the application of liquid. The printed areas containing liquid repellant remain dry and the areas without liquid repellent are selectively wetted out. The textile fabric is then subjected to pressurized heated gas which selectively carves the dry areas printed with liquid repellent leaving the wetted areas protected and uncarved. As an alternative embodiment, the yarns that make up a textile fabric can be individually treated with a liquid repellent prior to being formed into a textile fabric.

  • Patent number: 5855034
    Abstract: This Invention is a method and apparatus for spraying water on the underside of a series of colorant applicators in order to rinse excess colorant from the machine parts. There is a water manifold having a first end portion connected to an upper trolley by a pivoting joint and a second end portion attached to a lower trolley by both a pivoting joint and a sliding joint. Both the upper and lower trollies are constrained in the horizontal, vertical, and rotational direction by a series of cam followers. The extra degrees of freedom provided by the two pivoting joints and the sliding joint insure that no binding occurs. An optional feedback control system can be added utilizing a rotational position transducer to sense the angle of the water manifold so that the motion of the trolleys can be retarded or advanced accordingly.

  • Patent number: 5822835
    Abstract: A process for treatment of a web by means of impingement by high velocity gaseous fluid is provided. The process constitutes the provision of a web to two separate treatment zones. In the first treatment zone the web is subjected to the imposition of high velocity gaseous fluid substantially tangential to the web and in the opposite direction of travel by the web through the treatment zone, such that a series of saw-tooth waves are formed in and move along the web in the opposite direction of travel by the web. In the second conditioning zone, the same type imposition of high velocity gaseous fluid to the web occurs with the gas streams and the resultant saw-tooth waves forced in the same direction as the travel of the web. The two zones are separated by an area of high tension on the web. An apparatus for carrying out the process is also provided.
