[0027] Next, the present invention will be described in detail with reference to the drawings. Referring to Figures 1 to 4, the present invention provides a method 70 for forming an anti-counterfeiting feature at the knitting stage and its knitting Before describing method 70, the present specification first provides a basic understanding of the present invention. knitting 10 will be explained. knitting 10 is used in the manufacture of clothing, shoes or bags, knitting Reference numeral 10 denotes a knitted product produced by a knitting machine (not shown), which may be a warp knitting machine or a weft knitting machine, and the weft knitting machine includes a circular knitting machine and a flat knitting machine. knitting The body of the 10 includes a plurality of yarn loops 11, the plurality of yarn loops 11 being knitted with at least one first yarn 111; knitting A portion of 10 includes a plurality of characteristic thread loops 12, the plurality of characteristic thread loops 12 being formed by a second thread 121 and constituting an anti-counterfeiting feature 13, the anti-counterfeiting feature 13 being knitting It can be seen directly from ten aspects.

[0028] Furthermore, the first yarn 111 of the present invention comprises at least a band-like yarn, that is, the first yarn 111 may be a combination of multiple yarns, or may be a combination of multiple yarns twisted together using a twisting technique. Also, the second yarn 121 that forms multiple characteristic yarn loops 12 in the present invention is a combination of at least two child yarns 122, 123 twisted together using a twisting technique. After knitting multiple characteristic yarn loops 12 with the second yarn 121, the characteristic yarn loops 12 are formed by twisting at least two child yarns 122, 123. knittingThe color seen on the side of the yarn 10 is not constant but changes randomly. In the example of FIG. 1, one of the two child yarns 122, 123 is shown with a dot pattern, and the other of the two child yarns 122, 123 does not have a dot pattern. After the two child yarns 122, 123 are twisted together, the color of the plurality of characteristic yarn loops 12 changes randomly. knitting The dot pattern on the side of 10 is distributed arbitrarily and randomly. In other words, the color of one of the plurality of characteristic yarn loops 12 may be completely represented by one of the two child yarns 122, 123, or the color of one of the plurality of characteristic yarn loops 12 may be randomly generated by the two child yarns 122, 123.

[0029] Therefore, in the present invention, the plurality of characteristic thread loops 12 knitting The colors seen on the 10 sides change randomly, knitting 10, the anti-counterfeiting feature 13 is different, and the anti-counterfeiting feature 13 is prevented from being counterfeited or imitated, and knitting Imitation of the 10 will also be extinguished.

[0030] In addition, in the present invention, to highlight the anti-counterfeit feature 13, there is a color difference between the two child yarns 122, 123 and the first yarn 111. This color difference is described in the Natural Color System. In one embodiment, when the two child yarns 122, 123 belong to the same hue in the Natural Color System, there is a difference of at least three shades between the two child yarns 122, 123. Specifically, in the NCS Color Circle 20 formed by the four chromatic elementary colors (NCS elementary colors) yellow 21, red 22, blue 23, and green 24 of the Natural Color System shown in Figures 2 and 3, when two child yarns 122 and 123 both belong to the hue Y90R of the Natural Color System and shade S1050 (26 in the figure) located in the NCS Color Triangle 25 formed by the NCS Color Circle 20 shown in Figure 3 is selected as the shade of one of the two child yarns 122 and 123, shade S1020 (27 in the figure) or shade S6030 (28 in the figure), which is at least three shades away from the shade of the other child yarn 122 and 123, may be selected. That is, the color designation of one of the two child yarns 122, 123 is S1050-Y90R, and the color designation of the other is S1020-Y90R or S6030-Y90R. In other words, if the shade of one of the two child yarns 122, 123 is selected as shade S1050 (26 in the figure), which is located on the NCS color triangle 25 shown in Figure 3, the shade of the other of the two child yarns 122, 123 is at least three shades away, so shades S1070, S1060, S1040, S1030, S2060, S2050, S2040, S2030, S3050, S3040, and S3030 should be excluded from selection (these 11 shades have no symbols in Figure 3). In another embodiment, when two child yarns 122, 123 are located in different hues, the angle between the two hues forms a hue angle 29 (30) (see FIG. 2), and the hue angle 29 (30) should be equal to or greater than 30 degrees.For example, if a hue located in the Y10R range is selected for one of the two child yarns 122, 123, hues corresponding to the angle between Y10R and Y50R and hues corresponding to the angle between Y10R and G70Y should be excluded from selection for the other child yarn 122, 123. Furthermore, in one embodiment, there is a color difference between the two child yarns 122, 123 and the first yarn 111. Specifically, when the two child yarns 122, 123 and the first yarn 111 belong to the same hue in the natural color system, the two child yarns 122, 123 are each at least three shades apart from the first yarn 111, or when the two child yarns 122, 123 and the first yarn 111 are located in different hues, the angle between any two hues is 30 degrees or more.

[0031] In one embodiment, the two sub-yarns 122, 123 are set to be non-black to prevent the two sub-yarns 122, 123 from absorbing light when photographed by a photographing unit (not shown) of the recognition module, preventing the anti-counterfeit feature 13 from being recognized by the recognition module. Furthermore, the two sub-yarns 122, 123 are not reflective or metallic, because excessive reflections from the two sub-yarns 122, 123 during photographing would prevent the recognition module from recognizing them. Similarly, the two sub-yarns 122, 123 are not white or gray, a mixture of white and black, because light is mostly reflected when it hits a white object.

[0032] 1-4, a method 70 for forming the security feature 13 during the knitting stage of the present invention will now be described. The method 70 may be performed by any of the knitting machines described above, Using the knitting machine, the first yarn 111 knitting Step 71 to knit 10, The knitting machine in question knitting Step 72 of feeding a second yarn 121 when knitting up to the predetermined formation position of the 10 anti-counterfeit features 13; The knitting machine in question knitting When the knitting is completed beyond the predetermined formation position of the anti-counterfeit feature 13 of 10, the feeding of the second yarn 121 is stopped, and the knitting machine stops feeding the first yarn 111. knitting 10 and continuing to knit step 73.

[0033] Specifically, the knitting machine is knitting The main body (plurality of yarn loops 11) of the anti-counterfeiting feature 10 is formed, and then, when knitting is performed up to the position where the anti-counterfeiting feature 13 is to be formed, the knitting machine feeds the second yarn 121 instead of the first yarn 111, or when knitting is performed up to the position where the anti-counterfeiting feature 13 is to be formed, the knitting machine additionally feeds the second yarn 121 at the same time as feeding the first yarn 111, and performs a knitting operation using both the first yarn 111 and the second yarn 121, or when knitting is performed up to the position where the anti-counterfeiting feature 13 is to be formed, the knitting machine feeds the second yarn 121 at the same time as feeding the first yarn 111 using an embedded knitting technique (US9644291B1), and performs a knitting operation using both the first yarn 111 and the second yarn 121, knitting forming the anti-counterfeit feature 13 directly at the predetermined formation position of the anti-counterfeit feature 13 of the 10; knitting The anti-counterfeit feature 13 is formed on the surface of the second yarn 121. In addition, since the second yarn 121 is formed by twisting two child yarns 122 and 123, the color seen on the side of the second yarn 121 changes randomly. Next, the process proceeds to step 73, where the knitting machine moves past the predetermined formation position of the anti-counterfeit feature 13. knitting After knitting 10, the knitting machine stops feeding the second yarn 121 and continues knitting with the first yarn 111.

[0034] As can be seen from the above, in the present invention, the knitting machine forms a plurality of characteristic yarn loops 12 by a technique such as jacquard knitting during knitting. knitting The anti-counterfeiting feature 13 can be formed directly during the knitting of the yarn 10, and the second yarn 121 formed by twisting two child yarns 122 and 123 is random, so that the length of each characteristic yarn loop 12 is knitting The colors on the surface of the 10 are randomly distributed, and this random formation provides an anti-counterfeiting effect, and the anti-counterfeiting feature is knitting Because it is part of 10, it is even more difficult to counterfeit.

[0035] In addition to the straight stripe pattern shown in the accompanying drawings, the plurality of feature thread loops may also have other shapes depending on the design. In one embodiment, the overall width 131 of the anti-counterfeiting feature 13 is 1 inch or more.

[0036] In addition, since the first yarn 111 and the second yarn 121 have tension, after knitting the first yarn 111 and the second yarn 121, knitting The anti-counterfeiting feature 13 can be obtained by the knitting machine 10. To prevent the anti-counterfeiting feature 13 from being significantly shrunk by the tension of the yarn, making it unrecognizable, the needle pitch of the knitting machine is set to a range of 5G to 20G, meaning that the knitting needles are lowered 5 to 20 times per inch, so that each of the multiple characteristic yarn loops 12 knitted by the knitting machine has a width 132 of 1 millimeter (mm) or more after being subjected to tension, making the anti-counterfeiting feature 13 recognizable.
