Nonwoven Fabric (i.e., Nonwoven Strand Or Fiber Material) Patents (Class 442/327)
  • Patent number: 10807290
    Abstract: This invention involves a new and better solution to the problems associated with the premature softening of PLA filaments in the additive manufacturing of three dimensional articles. It is based upon the finding that poly(lactic acid) filaments with high crystallinity offer much better resistance to heat-induced softening. The crystalline poly(lactic acid) filament of this invention can accordingly be used in the additive manufacturing of three dimensional articles without encountering the problems associated with premature softening, such as poor quality and printer jamming. The crystalline poly(lactic acid) filaments of this invention can also be used in additive manufacturing of three dimensional articles without compromising the quality of the ultimate product, reducing printing speed, increasing cost, or leading to increased printer complexity.

  • Publication number: 20150082759
    Abstract: A holding sealing material includes inorganic fibers, a longitudinal direction, a width direction, a thickness direction, a first main face, a second main face, and a structure. The first main face is substantially perpendicular to the thickness direction. The holding sealing material is to be wrapped along the longitudinal direction around an exhaust gas treating body housed in a casing of an exhaust gas purifying apparatus and disposed between the exhaust gas treating body and the casing so that the first main face faces an outer circumference face of the exhaust gas treating body and the second main face faces an inner circumference face of the casing. The structure is plastically deformed by applying a shear stress to the first main face and the second main face respectively in mutually opposite directions along the width direction.

  • Patent number: 8987150
    Abstract: A fabric for use in chemical and biological (CB) protective garments includes at least one felt layer having from 25% to 100% carbon nanotube (CNT) fibers as a breathable physical barrier against toxic chemical droplets and/or pathogens. The felt layers are cleaned and consolidated into a mechanically competent sheet which can form adhesive seams having lapshear greater than the sheet itself. An additional supporting layer can be included. The supporting layer can be a wicking layer which is permeable with a chlorinated or otherwise chemically active solution to establish a reactive chemical barrier, the solution being dispensed on demand from a portable container. Embodiments include a second layer of CNT or of another backing fabric, sandwiching the wicking layer therebetween. Impermeable fluoropolymer seams can divide the fabric into a plurality of CNT/wicking cells. A layer of activated charcoal and/or halamine-forming hydantoin can be included for persistent reactive chemical protection.
