なかった。However, the method described in Japanese Patent Publication No. 47-43768 lowers the degree of orientation of the surface layer of the monofilament by treating the monofilament once drawn in steam. 1
The method disclosed in Japanese Patent No. 10918 is a method of increasing the degree of orientation in the inner layer and at the same time reducing the orientation in the surface layer by stretching in steam. In all of these conventional techniques, polyamide monofilaments that are already highly oriented and crystallized are treated in steam, and the inner layer is highly oriented and
There is a limit to the formation of a low orientation structure in the surface layer, and it is difficult to make the inner layer a higher orientation structure and the surface layer a lower orientation structure. Therefore, it has not been possible to produce polyamide monofilaments with even higher knot strength and durability.

Under any of these conditions, the processing of undrawn polyamide monofilament does not proceed smoothly. On the other hand, the water vapor pressure is 3
Processed polyamide monofilaments are exposed to water vapor at high pressures exceeding 0 0 mm H * 0, at high temperatures where the steam treatment temperature exceeds 160°C, or when the undrawn polyamide monofilament is exposed for more than 1.0 seconds.
