Alternatively, the coating applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device in the dryer section to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried. Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the dryer section or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.

  • Patent number: 7790217
    Abstract: A method of bonding an antimicrobial cationic polyelectrolyte to the surface of a substrate is described, wherein the antimicrobial thus attached to the substrate provides the substrate with antimicrobial properties, and at least a portion of the bonded antimicrobial is substantially non-leachable during normal conditions of use and storage. A method of manufacturing an antimicrobial material is described which comprises exposure of the substrate to a solution of antimicrobial cationic polyelectrolyte, followed by drying the exposed substrate thoroughly to impart a non-leaching property to at least a portion of the antimicrobial cationic polyelectrolytes.

  • Patent number: 7635745
    Abstract: Processes for the recovery of a sulfopolyester polymer from an aqueous dispersion and a sulfopolyester concentrate are provided. Particularly, a sulfopolyester concentrate, from which the sulfopolyester may be recovered and reused, are formed by processes such as evaporation and/or nanofiltration. Final recovery of the sulfopolyester may be achieved by further evaporation of water and/or salt precipitation. In addition, the recovered sulfopolyester and articles manufactured from the recovered sulfopolyester are also provided.
