    摘要: A MANUFACTURED MATERIAL AND A PROCESS FOR MAKING THE MATERIAL IS DISCLOSED. THE MANUFACTURED MATERIAL IS A HYDROGEN CONTAINING SUBSTANCE HAVING A FLUORINATED SURFACE AND IN WHICH HYDROGEN ATOMS, WHICH MAY BE PRESENT IN HYDROXYL RADICALS ATTACHED TO A CARBON ATOM CHAIN, HAVE BEEN REPLACED IN THE SURFACE OF THE MATERIAL BY FLUORINE ATOM OR RADICALS, AND WITH SUCH FLUORINATED SURFACE OF THE MATERIAL CONTAINING AT LEAST 2 MICROGRAMS OF SUCH FLUORINE PER CM.2 OF SURFACE AREA. THE PROCESS FOR MAKING SUCH A MATERIAL INCLUDES THE STEPS OF SELECTING A SUBSTRATE CONTAINING HYDROGEN ATOMS WHICH MAY BE PRESENT IN HYDROXYL RADICALS ATTACHED TO A CARBON ATOM CHAIN, SELECTING A GAS CONTAINING FLUORINE ATOMS OR RADICALS, PLACING THE SELECTED SUBSTRATE BETWEEN ELECTRODES IN A FLOWING ATMOSPHERE OF THE SELECTED GAS AT SUBATMOSPHERIC PRESSURE, AND SUBJECTING THE SUBSTRATE TO AN ELECTRODELESS DISCHARGE OF AT LEAST ABOUT 0.2 KWH./YARD2 TO CHEMICALLY ACTIVATE BOTH THE SURFACE OF THE SUBSTRATE AND THE GAS, AND EXCHANGE THE FLUORINE ATOMS OR RADICALS FOR SURFACE HYDROGEN ATOMS OR RADICALS TO PRODUCE A MATERIAL WITH A SURFACE, WHICH COMPARED TO THE SUBSTRATE BEFORE THIS PROCESS TREATMENT, IS MORE WATER REPELLENT (WITHOUT SEALING PORES), IS MORE CORROSION AND SOIL RESISTANT, MORE CHEMICALLY INERT, AND MORE LIKE THE RELATIVELY EXPENSIVE POLYTETRAFLUOROETHYLENE. WHEN THE SUBSTRATE IS A MATERIAL HAVING A RELATIVELY INERT SURFACE. SUCH AS POLYETHYLENE, THE PROCESS IS DISCLOSED AS INCLUDING AN INITIAL TREATMENT STEP THAT INVOLVES ION BOMBARDMENT OF THE SUBSTRATE IN HELIUM GAS TO ACTIVATE THE SURFACE BEFORE THE SURFACE IS TREATED IN THE FLUORINE CONTAINING GAS.

    摘要: The present invention provides a polyethylene fiber which can attain a high dye exhaustion rate, which indicates deep color, and which is excellent in dyeability and color fastness; a woven or knit textile that uses the polyethylene fiber, and that is excellent in cut-resistance and heat-retaining property, and a glove thereof. A polyethylene fiber of the present invention is characterized by having an intrinsic viscosity [η] of 0.8 dL/g or more and less than 5 dL/g; being composed of a repeating unit substantially derived from ethylene; having pores being formed from a surface of the fiber to an inside of the fiber; having an average diameter of the pores of ranging from 3 nm to 1 μm when the diameter is measured, by each pore being approximated by a column, at a contact angle of 140 degrees, in a mercury intrusion method; a porosity of the pores of ranging from 1.5% to 20% 1; or a thermal conductivity in a fiber axis direction at a temperature of 300 K of ranging from 6 W/mK to 50 W/mK.

    摘要: A modified porous non-conductor is provided wherein its outer and inner, surfaces have been treated by placing the porous non-conductor between a pair of electrodes which are located opposite to each other and carry a dielectric layer on a surface facing the other electrode, respectively, so that the porous non-conductor is brought into contact with both dielectric layers without coming into contact with the electrodes; and then, applying an alternating current voltage having a frequency of about 0.1 Khz to about 100 Khz between the electrodes to thereby induce an electric discharge in voids contained in the porous non-conductor and sandwiched between a pair of the electrodes.
