Best mode to perform the invention

The functional fiber for counterfeit prevention according to the present invention is by melt spinning a special Pigments, that of the composite fiber of the side-by-side type of two bonded Components mixed is produced. The first ingredient of the Namely, composite fibers become a masterbatch for melt spinning Processed by adding a special pigment to synthetic chips given large molecules, and then heated and mixed.

And the second ingredient is processed into a masterbatch for melt spinning by adding a special pigment to chips of synthetic large molecules and then heating and mixing,
and each masterbatch, that of the first ingredient and that of the second ingredient, is melted and spun to prepare a functional fiber for counterfeit prevention. The melt spinning of the masterbatch of the first ingredient and the second ingredient is performed by charging a weight ratio of 10-90 of the first ingredient and a weight ratio of 90-10 of the second ingredient to an extruder for spinning and then melt spun to have a diameter the fibers of 3-60 microns is achieved; This will produce a functional fiber.

Polyester, Nylon, polypropylene, polyethylene and polyurethane are considered the synthetic large molecules of the first ingredient and the second ingredient forming composite fibers, which are capable of being melted and spun.

The synthetic large molecules of the first ingredient and the second ingredient constituting the composite fibers be used so that the first Ingrediens and the second Ingrediens in terms of mixing properties with a special pigment are the same or different.

Even though Color pigments, fluorescent pigments, infrared pigments and the like as a special pigment, which is the synthetic big one Molecules of the first ingredient and the second ingredient, which are the composite fibers, mixed, used, is it possible for a monofilament to have a different Effect on visible radiation, ultraviolet radiation, infrared radiation and the like, by making a special pigment different to the synthetic large molecules of the first Ingrediens and the second ingredient is mixed.
