摘要:
The present invention provides a highly functional polyethylene fiber excellent in the cut resistance, has a high dimensional stability at about room temperature at which products are used, has a high shrinkage rate and stress, and excellent in forming processability when processed at a low temperature much less than a melting point of a polyethylene. And the present invention provides a highly functional polyethylene fiber excellent in processability at a low temperature, wherein an intrinsic viscosity [11] is higher than or equal to 0.8 dL/g, and is not higher than 4.9 dL/g, ethylene is substantially contained as a repeating unit, and a thermal stress at 40°C is lower than or equal to 0.05 cN/dtex, and a thermal stress at 70°C is higher than or equal to 0.05 cN/dtex, and is not higher than 0.25 cN/dtex. Further the present invention provides strings, ropes, woven/knitted textiles, and gloves thereof.
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 [·] 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:
An elastic fabric, characterized in that it contains a crosslinked polyolefin and exhibits a shrinkage of 8 % or less both in the longitudinal direction and the transverse direction after subjected to a heat treatment at 65 ° C under a dry condition for 30 minutes; and a method for producing the elastic fabric which comprises allowing a fabric containing a crosslinked polyolefin to shrink in a dyeing step, and then subjecting the resultant fabric to a finishing heat setting while stretching it at a percentage of 15 % or less or while relaxing it. The elastic fabric exhibits excellent resistance to chemicals, and also provide an product article excellent in dimensional stability, and thus can be suitably used as a fabric for sporting goods such as a swimsuit and a leotard, an inner fabric for a lady, a fabric for outer use.
