Embodiment 1～3、 comparative example 1～2
[0047] In the polyethylene terephthalate of 12mol% copolymerized isophthalic acid, mix and disperse 25% by weight of conductive carbon black to form a conductive polymer, use the conductive polymer as the conductive component, and use homopolyethylene as the conductive component. As a non-conductive component, phthalate is compounded according to the compounding ratio and compound structure of several conditions. While spinning, cooling and lubricating at 285°C, it is wound up at a speed of 1000m / min, and then stretched at 100°C. It was stretched on a roll, heat-treated on a hot plate at 140° C., and wound up to obtain conductive composite fibers Y1 to Y4. Table 1 shows the conductive performance of Y1 to Y4 and the coating ratio of the conductive component on the fiber surface.

[0056] A conductive polymer that mixes and disperses 35% by weight of carbon black in 6 nylon filaments is used as a conductive component, and 6 nylon filaments are used as a non-conductive component, and composited according to the composite ratio and composite structure of several conditions, at 275°C While spinning, cooling, and lubricating, it is coiled at a speed of 800m / min, then stretched on a drawing roll at 80°C, heat-treated on a hot plate at 140°C, and then coiled to make 330 dtex / 100 Filament conductive composite fibers Y6 to Y8. Table 3 shows the conductive properties of Y6 to Y8 and the coating ratio of the conductive component on the fiber surface.

Embodiment 6～8、 comparative example 4～5
[0064] Cloths 9 to 13 were produced in the same manner as in Example 4 except that the blending ratio of Y6 described above was changed. The physical property values of the formed nonwoven fabric are listed in Table 5.
[0065] Example 6
[0066] It can be seen from Table 5 that in Examples 6 to 8, with the increase of the blending ratio of the conductive composite fiber, the surface resistance and antistatic property tend to be better, and each result meets the requirements. However, in Comparative Example 4, the blending ratio was insufficient, and no effect was observed on surface resistance and antistatic properties. In addition, in Comparative Example 5, the surface resistance and the antistatic property reached a saturated state, which is considered to be due to the excess presence of the conductive conjugate fiber. Although there are no particular problems in process passability and various physical properties as a nonwoven fabric, it is not so good in te...
