  • the diffusivity of the fiber structure is 55 minutes or less, and the diffusivity of the knitted fabric is preferably 55 minutes or less and that of the woven fabric is preferably 45 minutes or less according to the diffusible residual water content test, method A-1, specified in ISO 17617 (dropping 0.6 mL of water).

  • the aqueous solution is rendered neutral, the dissolved resin is polymerized and adheres to the polyester fiber structure.
  • the amount of the resin is very small, and hence the resin adheres to the polyester fiber structure sparsely.
  • the resin sparsely adhering to the polyester fiber structure carries silver ions and imparts antibacterial properties to the fiber structure. Since the resin sparsely adheres to the polyester fibers and does not cover the entire surface, gaps are present between the antibacterial agent.
  • the antibacterial agent does not impair the effects of the hydrophilic polyester resin treatment agent of the antifouling properties, water absorptivity, and diffusivity.
  • the silver ions have a small molecular weight of about 47, it is preferable to adhere the silver ions to the surface of the fiber structure by padding, rather than the penetration of the silver ions into the amorphous portion of the polyester fibers by immersion.
  • the favorable molecular weight of the antibacterial agent that is suitable for the size of the pores in the amorphous portion of the polyester fibers ranges from 200 to 1000, and the molecular weight of the silver ions is smaller than 200, which allows the silver ions easily to escape from the pores in the amorphous portion of the polyester fibers and deteriorates the durability.
  • resin is dissolved in the aqueous solution of the silver ion-based antibacterial agent to make the polymerized resin carry the silver ions and intervene between the polyester fibers and the silver ions for enhanced bonding durability.
