  • Publication number: 20110151118
    Abstract: An apparatus and a system and method for treating a material are provided. The apparatus includes a vessel that includes a perforated core disposed within the vessel and a dip tube disposed within the core. The dip tube is in fluid communication with the treatment vessel at a first port and has at least one opening that is located within a non-perforated region of the perforated core and distal from the first port. The system includes a vessel that includes a perforated core disposed within the vessel and a dip tube disposed within the core. The dip tube is in fluid communication with the treatment vessel at a first port and has at least one opening that is located within a non-perforated region of the perforated core and distal from the first port. The system also includes at least one solution supply that comprises a solvent capable of changing phase in response to a change in temperature and/or pressure.

  • Patent number: 7825046
    Abstract: An article includes a microporous membrane. A porous fabric is laminated to the microporous membrane to form a laminate with a membrane side and a fabric side. A treatment material is applied to the laminate to form a treated laminate. The treated laminate having an oil resistance of at least a number 7 determined by AATCC 118 testing on both the membrane side and the fabric side. The treated laminate also has an air permeability through the treated laminate of at least 0.01 CFM per square foot determined by ASTM D737 testing.

  • Publication number: 20090220764
    Abstract: A method of making an article having an improved oleophobic property. The method includes the step of providing a microprous membrane. The method also includes the step of laminating a porous fabric to the microporous membrane to form a laminate with a membrane side and a fabric side. A treatment material is applied to the laminate to provide a treated laminate. The treated laminate has an oil resistance property of at least a number 7 determined by AATCC 118 testing on both the membrane side and the fabric side. The laminate also has an air permeability therethrough of at least 0.01 CFM per square foot determined by ASTM D737 testing.
