摘要:
The present invention provides a method for making the antimicrobial yarn. The present invention also provides a yarn with antimicrobial effects. The antimicrobial antifungal effect of the yarn is derived from nanosilver particles (diameter between 1 and 100 nm) which are adhered to the yarn. The yarn contains fibers which are made of cotton, linen, silk, wool, leather, blending fabric, synthetic fiber, or any combination thereof. The yarn can be used to make cloth to be used particularly for treating patients with burns or wound. The cloth made from the antimicrobial yarn can be further used to make clothes such as underwear, socks, shoe cushions, shoe linings, bed sheets, pillow cases, towels, women hygiene products, laboratory coats, and medical robes.
摘要:
An antimicrobial material comprising at least one yarn comprising fine fiber of 1.0 denier or less and at least one yarn comprising antimicrobial fiber that are engaged with each other, wherein the antimicrobial fibers impart an antimicrobial property to the entire material. In a preferred embodiment, the yarns of fine fiber and yarns of antimicrobial fiber are woven or knitted together. It is further preferred that the fine fiber be less than 0.3 denier, have a diameter of approximately 3 microns, and have a generally triangular cross-section with sharp edges, therefore allowing the fine fiber to substantially remove bacteria, fungi and other microbes from a surface. It is also preferred that the antimicrobial fibers comprise an acetate fiber spun together with polyester to give the antimicrobial fiber added strength.
摘要:
A sheet for pest control, wherein said sheet is of polymeric material and comprises at least two layers; a top layer and a bottom layer, wherein the bottom layer contains a herbicide and one or more pesticides selected from among fungicides and insecticides, and the top layer optionally containing an insecticide and/or fungicide. Other aspects of the invention include a polymeric composition used in the preparation of the sheets and a method for pest control in agriculture, horticulture and gardens.
摘要:
A food wrapping cloth (1) made of a fabric comprising warps produced by combining and twisting cellulose fiber yarns (3) and twisted yarns (2) produced by combining and twisting antimicrobial yarns (21) formed by vacuum depositing an antimicrobial metal onto a synthetic resin film and cutting the film into a thin elongated shape with cellulose fiber yarns (22) and wefts of cellulose fiber yarns (4).

This invention is a method of simultaneously and reliably impregnating a plurality of completed garments (10), such as Battle Dress Uniforms, made from conventional fabric with a target amount of permethrin that is within the range established by the Environmental Protective Association, yet effective to provide against insects. The method comprises the steps of providing an industrial washing machine (11), providing a holding tank (13) operably connected to the washing machine (11) for the transfer of liquids to and from the washing machine (11), determining the formula of permethrin and water required to impregnate the fabric of the garments (10) with the target amount of permethrin, providing an adequate quantity of the selected formula in the holding tank (13), operating the washing machine (11) through successive conventional wash and spin cycles with successive loads of garments, and while transferring the selected formula of permethrin and water between the washing machine (11) and holding tank (13) as required for conventional wash and spin cycles of the washing machine (11), without the potentially hazardous release of permethrin to the environment.
摘要:
p-sulfoxy cinnamic acid isolated from methanolic extracts of the eelgrass Zostera marina having significant antifouling aquatic properties. p-sulfoxy cinnamic acid was synthesized in the laboratory from p-coumaric acid, and antifouling activity was identical to the natural compound in laboratory bioassays. In addition, sulfate esters of other phenolic acids showed similar antifouling activity, suggesting that the sulfate ester was responsible for the antifouling effect.
摘要:
The formation of biofilms on surfaces in health-related environments can be prevented by the use of a compound represented by general structure (1), wherein X represents -OH, -O(aryl), -O(acyl), -O(sulfonyl), -CN, F, Cl, or Br; Y represents O, S, Se, or NR; Z represents optionally substituted alkyl, heteroalkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, aralkyl, heteroaralkyl, or -(CH2)m-R80; R represents independently for each occurrence hydrogen, alkyl, heteroalkyl, aryl, heteroaryl, aralkyl, heteroalkyl, or -(CH2)m-R80; R80 represents independently for each occurrence aryl, cycloalkyl, cycloalkenyl, heterocyclyl, or polycyclyl; and m is an integer in the range 0 to 8 inclusive, and by preventing the formation of biofilms, the compounds formulated according to the present invention can be used in the fabrication of grafts, implants, medical devices in order to prevent infection thereof. The compounds formulated according to the present invention display an additional anticoagulant property, permitting their use in settings where decrease in blood coagulability is desirable.
摘要:
A carbon-carbon composite clutch friction material for use with a wet lubricant under severe operating conditions is disclosed, the material comprising a woven carbon fabric mesh (suitably a satin weave mesh) infiltrated with pyrolytic carbon to an unusually high density in the range of at least 1.3 g/cc to about 1.5 g/cc. By infiltrating the woven carbon fabric with carbon to such high density, a wear-resistant friction material is provided that still retains enough surface texture for lubricant transport.
