InactiveUS20060159641A1Minimal shrinkageImprove the immunityCosmetic preparationsHair removalHigh concentrationMedicine
Non-glutaraldehyde fixation of an organ or a prosthesis for implantation in a mammal is based upon carbodiimide treatment. A solution containing a sterilizing agent, such as EDC, in combination with a coupling enhancer, such as Sulfo-NHS, and a high concentration of a diamine cross linking agent is used. As a result, only minimal surface reduction occurs during fixation, and the resultant products show a dramatic increase in resistance to calcification.

The present invention relates to electrochromic polymeric solid films, manufacturing electrochromic devices using such solid films and processes for making such solid films and devices. The electrochromic polymeric solid films of the present invention exhibit beneficial properties and characteristics, especially when compared to known electrochromic media. The electrochromic polymeric solid films are transformed in situ from a low viscosity electrochromic monomer composition by exposure to electromagnetic radiation, and in so doing minimum shrinkage occurs. The electrochromic polymeric solid films of the present invention also perform well under prolonged coloration, outdoor weathering and all-climate exposure, and provide an inherent safety aspect not known to electrochromic media heretofore.

Wet-lay flame barrier
InactiveUS20060068675A1Increase speedExtension of timeDomestic upholsteryLayered productsFiberGlass fiber
Nonwoven wet-lay flame barrier of the invention comprises a blend of water dispersible fibers, that are inherently fire resistant and nonshrinking to direct flame, along with water dispersible fibers extruded from polymers made with halogenated monomers and optionally including fiberglass and wood pulp, being together thermally bonded with a binder resin in a wet-lay manufacturing process to provide a relatively thin, but dense, durable flame barrier with excellent tensile, and durability properties in the end use application. The wet-lay flame barrier of this invention also allows for the manufacture of open flame resistant composite articles, while also permitting the continued use of conventional non-flame retardant dress cover fabrics, conventional non-flame retardant fiberfills and conventional non-flame retardant polyurethane foams.

Slickened or siliconized flame resistant fiber blends
InactiveUS20060160454A1Extinguish any residual flameMinimal shrinkageDomestic upholsteryFibre treatmentFiberPolymer science
The invention relates to slickened or siliconized flame resistant fiber blends that are well suited for use in mattresses, boxsprings, upholstered furniture, fiber-filled bed clothing, transportation seating or any end use application where a soft materials are desired for flame resistant (FR) purposes. Some of the fibers in the blend are slickened. The FR fibers incorporated into these blends include both char forming FR fibers and oxygen depleting FR fibers. FR char-forming fibers are those which exhibit little shrinkage when exposed to direct flame and are not spun from polymers manufactured with halogenated monomers. Oxygen depleting FR fibers are spun from polymers manufactured with halogenated monomers.

A microvoided film formed by mixing a microvoid forming additive with a composition including a polymeric material. The microvoided film includes a printability additive. The microvoids formed during the processing of the composition to convert it into a film result in a reduction of the density of the film, making a lighter weight film requiring less polymeric material to produce a film of desired thickness while maintaining suitable structural characteristics. The microvoids are formed through β crystallization of the polymeric material during a cold drawing stage of the film fabrication process. The microvoided film may be fabricated to be opaque with or without pigment additive included in the composition.
