Including Particulate Material Other Than Fiber Patents (Class 442/325)
  • Patent number: 8820028
    Abstract: A method of reducing the amount of cooling energy required to heat and cool a building is provided. The method includes disposing a porous insulating material in the exterior walls and substantially covering the ceiling in the attic space of the building to a substantial depth. The porous insulating material includes a desiccant. The method further includes permitting the desiccant—bearing porous insulating material to adsorb water moisture from the attic space and then permitting the adsorbed water moisture to desorb from the desiccant—bearing porous insulating material into the enclosed room of the building, resulting in a reduction in the amount of energy required to heat and cool the building.

  • Publication number: 20120036733
    Abstract: The invention relates to a felt material comprising at least one felt layer and an absorbing layer, to a method for producing the felt material, and to the use of the felt material in textiles, shoes, technical application or medical applications. The felt material according to the invention has the advantages of conventional felt materials regarding the warming and damping properties and is permeable to air in the dry state. Due to the special design, however, it is waterproof in the wet state and thus it is suitable for sealing many materials. The felt material according to the invention binds more humidity or binds water in a different way than common felt materials.

  • Patent number: 6767850
    Abstract: A flat textile material (10) has an upper side and an underside and is used, in particular, as a clothing fabric. For the purpose of controlling the permeability of the textile material (10), control elements (34, 36; 16, 18) are provided which are deformable by an environmental parameter. Media whose permeation is controlled thus are, for example, fluids or light. Possible environmental parameters are, for example, the temperature or the air humidity. It is thus possible to make, for example, textile materials whose breathing activity increases with the body temperature of the user.

  • Patent number: 6753274
    Abstract: Disclosed herein is a stabproof and bulletproof panel. The stabproof and bulletproof panel includes a bulletproof panel 40 and a plurality of stabproof panels 60. The bulletproof panel 40 is comprised of a front plate 45, a plurality of high density polyethylene films 44 stacked with one on top of another for dispersing impact energy, and a rear plate 46 formed by sewing together a plurality of aromatic polyamide woven fabrics for minimizing frictional heat and deformation. The front plate 45 consists of a plurality of aromatic polyamide woven fabrics 41, a felt 50 formed by forcibly inserting thin aromatic polyamide fibers or high density polyethylene fibers 52 and a shock-absorbing member 51 into a scrim woven in the form of a net using aromatic polyamide fibers or high density polyethylene yarn, and a plurality of aromatic polyamide woven fabrics 43. The stabproof panels 60 are brought into tight contact with the front surface of the bulletproof panel 40.

  • Patent number: 6610390
    Abstract: A nonwoven has low tensile and high elongation in the first direction (typically the CD) and high tensile and low elongation in the second direction (typically the MD). The nonwoven has a plurality of bonding points defining a total bonding area along the second direction greater than along the first direction. Accordingly, the nonwoven has unbonded fiber portions and bonded fiber portions, with a bonded portion/unbonded portion ratio greater along the second direction than along the first direction. The bonding points are preferably either circular or oval in plan.
