Interweave, braiding etc. is after modes form texture cell 2, vision can effectively further be avoided to cheat or even the artificial frauds hand such as put
Section further improves the difficulty being imitated of anti-counterfeit sign with random texture 1.
Further, the first fiber 21 mentioned above, the second fiber 22, the 3rd fiber 23 and the 4th fiber 24,
In actual use, there is at least one fiber using color scheme fiber 3, color scheme fiber 3 is by least two different colors
Material part is made.
At least one in multiple fiber in texture cell 2 uses color scheme fiber 3, and color scheme fiber 3 is by extremely
Few two different colors of material part composition, then utilize the multiple fiber containing color scheme fiber 3 by being stacked with,
Interweave, braiding etc. is after modes form texture cell 2, vision can effectively further be avoided to cheat or even the artificial frauds hand such as put
Section further improves the difficulty being imitated of anti-counterfeit sign with random texture 1.
The diversified forms with regard to color scheme fiber 3 are illustrated respectively below is described, but it should be noted that, color scheme is fine
The form of dimension 3 includes but not limited to following several forms：
Form one：Multiple material part can on the extending direction of fiber step-by-step arrangement successively；Form two：As shown in fig. 7,
Color scheme fiber 3 includes the first material part 31 and the second material part 32, and the first material part 31 is located at the second material
Expect the top of part 32, i.e., on the cross section of color scheme fiber 3, the first material part 31 and the second material part 32 are in point
Laminar is arranged；Form three：As shown in figure 8, color scheme fiber 3 includes the first material part 31, the second material part 32 and the
Three material parts 33, and the first material part 31 is located at the top of the second material part 32, the 3rd material part 33 are located at the
The lower section of two material parts 32；I.e. on the cross section of color scheme fiber 3, the first material part 31, the second material part 32
It is arranged with the 3rd material part 33 in layer-stepping；Form four：As shown in figure 9, color scheme fiber 3 includes the first material part
31st, the second material part 32 and the 3rd material part 33, and the first material part 31, the second material part 32 and the 3rd material
