に示す。Example 2 In Example 1, instead of the nylon 12 polymer,
Using a copolymer of nylon 6 and nylon 66 with a melting point of 180°C (nylon 6: nylon 66 = 75: 25 weight ratio), melt spinning and stretching were performed in the same manner as in Example 1, and the content of naphthiomate T was was measured. The results are shown in Table 1.
比較例１および２

示すように変更した以外は同様に行った。Comparative Examples 1 and 2 The same procedures as in Example 1 were carried out except that the polymer and melting temperature were changed as shown in Table 1.

紡糸できない。これに対して、本発明の範囲内（実施例
１および２）では、ナフチオメートＴの分解がほとんど
おこらず、繊維中の含有量も添加量とほとんど変わらな
い。(Page 1 of the book, blank space below) As is clear from the results in Table 1, the melting point of the polymer is 2.
00°C or higher, if emphasis is placed on the melting temperature of the polymer (Comparative Example 1), naphthiome-1-T will decompose and the amount contained in the fiber will decrease, while on the other hand, the antibacterial agent will decompose. When emphasis is placed on deterrence (Comparative Example 2), the melting temperature is too low to allow spinning. On the other hand, within the scope of the present invention (Examples 1 and 2), naphthiomate T is hardly decomposed, and the content in the fiber is almost the same as the amount added.
