いう欠点を有していた。However, it is very difficult to spin activated fibers to make filament bundle activated carbon. There is also a method of spun yarn before activation, or activating the filament yarn as it is or as a twisted strand, but activated carbon from spun yarn or twisted yarn has a low yarn strength. Processing into low woven and knitted fabrics 11
In addition, filament bundle activated carbon has adsorption properties, particularly slow adsorption speed. On the other hand, activated carbon made from untwisted filament yarns has the disadvantage that it is difficult to process into woven or knitted fabrics.

/Q, tearing strength is 1g, 3g, 30g, respectively.
Twelve types of filament bundle activated carbons weighing 60 g were obtained. These fibers were passed through an air spinning machine, which is a process for making cotton yarn, to produce one culm of a core yarn having a fine count of 11.3 Nm single yarn and a filament bundle with an activated carbon content of 10%. Table 1 shows the bundles investigated for the stability of the process when making core yarn and the adsorption rate of the obtained core yarn, and those that fall within the scope of the present invention have excellent process stability and high adsorption. showed speed.
