  • Patent number: 6596033
    Abstract: The invention is lyocell fiber characterized by a pebbled surface as seen at high magnification and having a variable cross section and diameter along and between fibers. The fiber is produced by centrifugal spinning, melt blowing or its spunbonding variation. The fibers can be made in the microdenier range with average weights as low as one denier or less. The fibers have inherently low gloss and can be formed into tight yarns for making fabrics of very soft hand. Alternatively, the fibers can be formed into self bonded nonwoven fabrics.

  • Patent number: 6461386
    Abstract: Specific transfer methods and articles to impart a metal-ion based antimicrobial finish to recipient textile surfaces. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. In particular, the inventive method involves the application of a solid, inorganic antimicrobial material to a donor substrate (such as a dryer sheet), and the subsequent placement of such a substrate within a tumble drying machine containing textile fabrics and operating the machine. The donor substrate, upon contact with the recipient textile fabrics, transfers antimicrobially effective amounts of the metal-ion based compounds to such recipient fabrics thereby imparting at least a temporary antimicrobial finish over at least a portion of such fabrics. The donor substrates, with either the antimicrobial compound alone or mixed with standard tumble dryer additives (such as perfumes, fabric softeners, fiber lubricants, and the like) are also contemplated within this invention.

  • Patent number: 6416558
    Abstract: A water based fiber treatment agent and fiber treatment method impart to treated fibers a perfect smoothness, lubricity, reduced tackiness, and pleasant tactile sensations. The water based fiber treatment agent contains a silicone oil emulsion of crosslinked silicone particles with an average diameter of 0.01 to 100 &mgr;m which are in silicone oil drops having an average diameter of 0.05 to 500 &mgr;m, and then the silicone oil drops are dispersed in water. The diameter of the crosslinked silicone particles is smaller than the diameter of the silicone oil drops.

  • Patent number: 6001282
    Abstract: An electromagnetic shield (20) for protecting individuals from the adverse effects of electromagnetic radiation includes a homogenous composition of finely ground tourmaline and a porous carrier. The electromagnetic shield (20) is attached to a radiating device such as the handset of a portable telephone. The tourmaline reacts with moisture in the air to produce negative ions which cancel the positive ions created by the radiating device, thereby substantially reducing or eliminating the harmful effects of the radiation. The electromagnetic shield (20) composition can be molded into housings for radiating devices.
