- the like can be used as the ionomer resin.
- the concentration of the ionomer resin in the second treatment agent is preferably 5% by weight or more and 20% by weight or less. This is because if it is less than 5% by weight, a sufficient adhesion effect is hardly exhibited, and if it exceeds 20% by weight, the resulting fiber becomes too hard and the fatigue resistance may be lowered.
- Block isocyanate compound As the blocked isocyanate compound used for the second treating agent, any of those usable for the first treating agent can be used.

This is because if it is less than 5 parts by weight, the adhesive strength may be lowered, and if it exceeds 30 parts by weight, the resulting fiber becomes too hard and the fatigue resistance may be lowered.
- the total solid concentration of the second treating agent is preferably 5% by weight or more and 30% by weight or less, and more preferably 10% by weight or more and 25% by weight or less. This is because a higher adhesive force can be obtained for rubber containing ethylene propylene rubber. If the amount is less than 5% by weight, the amount of the second treatment agent-containing component attached to the organic fiber is small, and sufficient adhesive strength may not be obtained. If the amount exceeds 30% by weight, the resulting fiber becomes hard, This is because the bending fatigue strength and the like may be lowered.
- the first treatment agent or the second treatment agent is preferably aqueous, that is, contains water or a solvent containing water as a main component.
