ることが最近発表された（電子返信学会、昭和５８年綜
合全国大会、予稿集７−３００）。(Prior art) It has been known that when polyoxymethylene is stretched under certain specific conditions, its crystal orientation, strength, and elastic modulus improve. When superstretched, the tensile strength is 1.7 GP
It was recently announced that a superstretched body having a tensile modulus of elasticity of 60 GPa can be obtained (Electronic Reply Society, 1981 National Conference, Proceedings 7-300).

目立ち、逐にはそこが破断点となるおそれもある。Although it has been suggested that such a superstretched product can be used as a tensile strength member for optical fiber cables, it is also expected to be used as a wire rope due to its physical properties. Although this superstretched material has excellent mechanical properties as described above, it has the disadvantage that it is easily fibrillated because it is in a nearly 100% orientation state. If this is used in a manner where it is repeatedly rubbed like a robe, fuzz will become noticeable, and there is a risk that this will eventually become a breaking point.

In addition to prevention, protection from the environment can be achieved. In other words, polyoxymethylene is originally an engineering resin with excellent heat resistance, water resistance, oil resistance, and weather resistance, but it is still susceptible to strong acids, strong alkalis, etc., so it can be coated with polyethylene, polyvinyl chloride, synthetic rubber, etc. Provides protection from corrosive substances.

kg/mrrf and a tensile modulus of 25 GPa were twisted into a rope shape. This was passed through an extruder having a coating die and coated with polyvinyl chloride resin to obtain a coated body having a cross-sectional shape as shown in FIG.

In addition, uncoated rope is straight B 20 m/m
When the coated body of the present invention was wrapped around a steel rod and squeezed, fluffing became noticeable after several tens of times, but no change in the external shape was observed in the coated body of the present invention. It was confirmed that no change in the physical properties of the superstretched body itself was observed due to the coating.
