The safety gloves of the present invention, an example of which is shown in the drawing, are made of ultra-high molecular weight polyethylene with an intrinsic viscosity [η] of 5 dl/g or more, a tensile modulus of elasticity of 30 GPa or more, and a tensile strength of 30 GPa or more.
It is made by knitting fibers with a strength of 1.5 GPa or more and an elongation of 6% or less. It has excellent wear resistance and durability. The ultra-high molecular weight polyethylene used in this invention has an intrinsic viscosity [η] of 5 at 135°C in decalin solvent.
dl/g or more, preferably in the range of 7 to 30 dl/g. When [η] is less than 5 dl/g, it is easy to form fibers, but even when stretched, fibers with excellent tensile strength cannot be obtained. On the other hand, the upper limit of [η] is not particularly limited, but if it exceeds 30 dl/g, it tends to be difficult to form fibers. The above-mentioned ultra-high molecular weight polyethylene is obtained by polymerizing ethylene or ethylene and a small amount of other α-olefins such as propylene, 1-butene, 4-methyl-1-pentene, 1-hexene, etc. by a so-called medium-low pressure polymerization method. There is a range of polyethylenes with much higher molecular weights. In addition, the ultra-high molecular weight polyethylene fibers in the present invention are fibers, tapes, or fibers obtained by fibrillating tapes, which have highly oriented ultra-high molecular weight polyethylene molecular chains and have high elastic modulus and high tensile strength. . The method for producing fibers having such characteristics is not particularly limited, but for example,
15408, a method of diluting ultra-high molecular weight polyethylene with a solvent and then spinning and drawing, as described in JP-A-58-5228, or JP-A-58-5228.
It can be prepared by the method disclosed in Japanese Patent Application Laid-open No. 168116 and Japanese Patent Application Laid-open No. 187614/1983. The ultra-high molecular weight polyethylene fiber used in the present invention has a tensile modulus (initial) of 30 GPa or more, preferably 50 GPa or more,
It is preferable that the tensile strength is 1.5 GPa or more, preferably 1.7 GPa or more, and the elongation is 6% or less, preferably 4% or less. Aramid fibers, which have the highest strength among the fibers currently in use, can only be spun into staples, but fibrillated yarns made from ultra-high molecular weight polyethylene can be knitted as long fibers. Of course, it may be stapled, spun, and then knitted.

ケーの手袋としても使用できる。[Function] Ultra-high molecular weight polyethylene fibers usually have a tensile modulus (initial) of 8 to 15 GPa and a tensile strength of 0.6 to 1.0 GPa, which is almost double that of general-purpose polyethylene fibers. It has a much higher strength, has much better abrasion resistance, and is difficult to break even when it comes into contact with sharp edges, so it is durable even with thin gloves. Effects of the invention The safety gloves of the invention have sufficient durability even if they are thin. The thinner it is, the better it feels in your hand when you grab something. Also, it is difficult to cut when hit by a knife, etc., so it protects your hands safely. Therefore, it is suitable for work in factories and construction sites. They are also useful for sports; for example, they can be used as baseball gloves with cushioning material to make them extremely durable, and they can also be used as skiing or ice hockey gloves because they do not break easily even when hit with sharp edges. can also be used.
