Description

防伪纤维和含有该防伪纤维的防伪纸及其制造方法Anti-counterfeit fiber and anti-counterfeit paper containing the same and manufacturing method thereof

技术领域Technical field

本发明属于防伪技术领域，具体地涉及一种防伪纤维、含有该防伪纤维的防伪纸及其制造方法。The invention belongs to the technical field of anti-counterfeiting, and in particular relates to an anti-counterfeit fiber, a security paper containing the anti-counterfeit fiber and a manufacturing method thereof.

背景技术Background technique

造纸防伪材料作为一种重要的防伪手段已广泛应用于各种防伪领域，例如世界上几乎所有的钞票纸均采用了造纸防伪材料，进一步，几乎所有的造纸防伪材料采用的是防伪纤维，其几何形状均采用条状细线，而片状(比如，单纯点状)的防伪纤维却很少采用，究其原因主要有以下几点：第一，条状细线的视觉特征容易捕捉，相对于相同的表面积的其它形状其视觉特征最明显；第二：条状细线在造纸过程中容易与纸纤维交合，增加对纸张的附着力，印刷时特别是满版印刷时条状细线不会脱落，而片状防伪纤维容易脱落；第三，如果将条状细线做成单根多色段纤维，由于各色线段间需要精确的连接对位，印刷模仿有很大的难度。目前常见的单根多色段防伪纤维，即在一根纤维上具有不同的颜色段的防伪纤维，已在造纸防伪材料中多有应用，例如应用在印度的纸币、中国的多种防伪纸张中。这种防伪纤维的制造工艺是，先在薄膜上通过印刷方式印上彩条，然后再用刀切成长条，由于这种工艺十分简单，其采用的印刷为普通的印刷，其分切的切刀为普通切刀，均为市面上随处可得的通用设备，因此其防伪效果已大为降低；再者，切刀工艺成本高，且无法切成很细的细丝(防伪纤维的宽度受限)，这对造纸的附着力十分有害；另外，受到印刷工艺的限制，得到的防伪纤维的色彩视觉特征较为单一，对其进行仿造相对容易，其防伪效果不足以满足现在越来越高的防伪要求；工艺中由印刷手段形成的色彩在耐磨损、耐恶劣环境等方面都存在问题。如果本领域技术人员试图将印刷薄膜加切刀分切形成的条状纤维制作成点线结构，那么由于点线结构是区别于等宽条状纤维的更为复杂的结构，切刀切割无法实现而需要通过冲压工艺完成，冲压工艺得到的点线结构印刷薄膜的最大缺点是其尺寸受到限制，只能做成较大尺寸,也相应地只能用作造纸安全线、无法用做造纸防伪纤维；另外，即使未来有新的设备出现可以冲压小尺寸的点线结构，也无法解决小尺寸冲压时的色彩、图案间的精确对位问题。As an important anti-counterfeiting method, paper anti-counterfeiting materials have been widely used in various anti-counterfeiting fields. For example, almost all banknote papers in the world use paper-making anti-counterfeiting materials. Further, almost all paper-making anti-counterfeiting materials use anti-counterfeiting fibers, and their geometry The shapes are all strip-shaped thin lines, while the sheet-like (for example, simple point-like) anti-counterfeiting fibers are rarely used. The main reasons are as follows: First, the visual characteristics of strip-shaped thin lines are easy to capture, as opposed to Other shapes of the same surface area have the most obvious visual characteristics; second: the strip-shaped thin lines are easy to cross with the paper fibers during the papermaking process, increasing the adhesion to the paper, and the strip-shaped fine lines are not printed during printing, especially in full-page printing. It is detached, and the sheet-like anti-counterfeit fiber is easy to fall off. Thirdly, if the strip-shaped thin wire is made into a single multi-color segment fiber, printing imitation is very difficult because of the need for precise connection alignment between the color line segments. At present, a single multi-color segment anti-counterfeiting fiber, that is, an anti-counterfeiting fiber having different color segments on one fiber, has been widely used in paper anti-counterfeiting materials, for example, in Indian banknotes, and various anti-counterfeit papers in China. . The manufacturing process of the anti-counterfeiting fiber is that the color strip is printed on the film by printing first, and then the strip is cut by a knife. Since the process is very simple, the printing used is ordinary printing, and the cutting is cut. The knife is a common cutter, which is a universal equipment available anywhere in the market, so its anti-counterfeiting effect has been greatly reduced; in addition, the cutter process cost is high, and it cannot be cut into very fine filaments (the width of the anti-counterfeit fiber is affected by Limitation), which is very harmful to the adhesion of papermaking; in addition, due to the limitation of the printing process, the color visual characteristics of the obtained anti-counterfeit fibers are relatively simple, and it is relatively easy to counterfeit, and the anti-counterfeiting effect is insufficient to meet the current higher and higher Anti-counterfeiting requirements; the color formed by printing means in the process has problems in terms of wear resistance and harsh environment. If a person skilled in the art attempts to make a strip-shaped fiber formed by slitting a printed film and a cutter into a dotted line structure, since the dotted line structure is a more complicated structure different from the equal-width strip-shaped fiber, the cutter cutting cannot be realized. However, it needs to be completed by the stamping process. The biggest disadvantage of the dot-line structure printed film obtained by the stamping process is that its size is limited, and it can only be made into a larger size, and accordingly can only be used as a paper safety thread, and can not be used as a papermaking anti-counterfeit fiber. In addition, even if there is a new device in the future, it is possible to punch a small-sized dotted line structure, and it is impossible to solve the problem of accurate alignment between colors and patterns in small-size stamping.

技术效果：Technical effect:

本发明提供了一种防伪纤维，该防伪纤维为沿条状纤维的横向切削成的一体的点线结构，该点线结构本身具有现有的条状细线结构防伪纤维的所有优点，包括：这种结构的防伪纤维是防伪纸张中最常用的防伪纤维；视觉特征明显；在造纸过程中，和纸浆容易交合，增加防伪纤维对纸张的附着力等。同时，现有的条状等宽细线的防伪纤维通过印刷薄膜加切刀分切的工艺可被模仿，而本发明的点线结构无法通过印刷薄膜加切刀分切的工艺实现仿造，也无法通过印刷薄膜加冲压工艺实现，因为切刀无法切割点线结构，冲压工艺无法实施小尺寸的冲压也无法保证冲压时色彩和图案的精确对位。比如，对于点的宽度为100um，连线的宽度为30um的点线结构的防伪纤维，印刷薄膜加冲压工艺就根本无法生产，其主要原因有二：其一：冲压模具不可能冲压到如此小的尺寸；其二，无法保证色彩和图案的精确对位。由于点线结构为一体结构，因此特定色彩结构也为一体结构，也解决了现有工艺中由印刷手段形成色彩而构成双层结构在耐磨损、耐恶劣环境等方面的问题。本发明的防伪纤维的点线结构的具有色彩视觉特征的特定色彩结构沿着所述条状纤维的长度方向延伸，使得点线结构的色彩视觉特征为立体结构产生的色彩视觉特征，完全不同于印刷薄膜得到的平面的视觉特征，是印刷油墨无法模仿的视觉特征，且视觉特征丰富、可按需灵活变化。由于所述防伪纤维沿条状纤维的横向切削成，所述防伪纤维由独有的设备生产，色彩是首先已经在尺寸较大的条状纤维上安排好，因此再将其切成防伪纤维时，尺寸及图像色块对位的可控性好，形状规格可以多样化，色彩特征丰富。The invention provides an anti-counterfeit fiber which is an integrated dotted structure which is cut along the transverse direction of the strip fiber, and the dotted line structure itself has all the advantages of the existing strip-shaped fine-line structure anti-counterfeit fiber, including: The anti-counterfeit fiber of the structure is the most commonly used anti-counterfeit fiber in the anti-counterfeit paper; the visual characteristics are obvious; in the papermaking process, the pulp is easily mixed, and the adhesion of the anti-counterfeit fiber to the paper is increased. At the same time, the existing anti-counterfeit fibers of the strip-shaped equal-width thin line can be imitated by the process of cutting the cutting film and the cutter, and the dotted line structure of the present invention cannot be counterfeited by the process of printing the film and the slitting of the cutter, It cannot be realized by the printing film plus stamping process, because the cutter cannot cut the dotted line structure, the stamping process cannot implement the small-size stamping, and the precise alignment of the color and the pattern during the stamping cannot be guaranteed. For example, for the anti-counterfeit fiber with a dot width of 100um and a line width of 30um, the printing film and the stamping process cannot be produced at all. The main reasons are two: one: the stamping die cannot be stamped so small. The size; second, the exact alignment of colors and patterns cannot be guaranteed. Since the dotted line structure is an integral structure, the specific color structure is also an integrated structure, and also solves the problems in the prior art that the color formed by the printing means forms a double-layer structure in terms of wear resistance and harsh environment. The specific color structure of the dotted line structure of the anti-counterfeit fiber having the color visual feature extends along the length direction of the strip fiber, so that the color visual feature of the dotted line structure is a color visual feature generated by the three-dimensional structure, which is completely different from The planar visual characteristics obtained by the printed film are visual features that the printing ink cannot imitate, and the visual features are rich and can be flexibly changed as needed. Since the security fiber is cut along the transverse direction of the strip fibers, the anti-counterfeit fiber is produced by a unique device, and the color is first arranged on the strip fiber having a larger size, so that when it is cut into the anti-counterfeit fiber, The size and image color block have good controllability, and the shape specifications can be diversified and the color features are rich.

另外，本发明的防伪纤维的点线结构对应于独特的加工设备和独特的模具，设备和模具都是市场上无法得到又难以仿制的，极大地提高了防伪纤维的防伪性能。In addition, the dotted line structure of the anti-counterfeit fiber of the present invention corresponds to a unique processing equipment and a unique mold, and the equipment and the mold are both unobtainable and difficult to imitate on the market, and the anti-counterfeiting performance of the anti-counterfeit fiber is greatly improved.

优选地，条状纤维采用一次性的熔融纺丝成形的工艺，后续切削不存在色彩和图案的对位问题，另外，条状纤维还可通过二次牵伸减小横截面的面积，进而降低点线结构的尺寸。Preferably, the strip fiber adopts a one-time melt spinning forming process, and the subsequent cutting does not have the problem of alignment of color and pattern. In addition, the strip fiber can also reduce the cross-sectional area by secondary drawing, thereby reducing The size of the dotted line structure.

本发明的一体的点线结构的防伪纤维，在抄入纸张后，在视觉特征上十分容易地与现有的细线状的防伪纤维(尤其与等宽的细线状的防伪纤维)区分开来，而本发明的点线结构又是通过印刷薄膜加分切工艺或通过印刷薄膜加冲压工艺无法模仿的，彻底地解决了原有的印刷薄膜分切的单根多色段纤维容易被造假者仿制的难题。The integral anti-counterfeit fiber of the dotted line structure of the present invention is easily distinguished from the existing thin-line anti-counterfeit fibers (especially with the thin-width anti-counterfeit fibers of equal width) in visual characteristics after being copied into the paper. However, the dotted line structure of the present invention can not be imitated by the printing film plus slitting process or by the printing film plus stamping process, and completely solves the problem that the original printed film slitting single multi-color segment fiber is easily falsified. The problem of imitation.

具体实施方式detailed description

为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

图1示出了沿条状纤维A的横向切削并得到的一体的点线结构的防伪纤维1，防伪纤维1包括两个对应的切刀面，其中条状纤维A沿其长度方向L上包含使点线结构具有彩色视觉特征的特定色彩结构，所述色彩视觉特征是指其直接或间接被人眼感知的色彩特征。在生产条状纤维A时，特定色彩结构沿在条状纤维A的横向上分布、沿条状纤维长度方向平行非扭曲延伸，因此，点线结构的特定色彩结构不存在对位问题，且特定色彩结构沿点线结构的厚度贯穿，形成立体视觉效果。这里的横向包括垂直于条状纤维长度方向的垂直横向和与长度方向成非90度角的倾斜横向。图2为从其中的一个切刀面观察该防伪纤维的俯视图。防伪纤维1整体呈直线形、包括三个点2和两条连线3，其点2和连线3交替排列(即，点线结构中每个点2的相连端均是与连线3相连)。防伪纤维1包括具有色彩视觉特征的一个或多个特定色彩结构，每个特定色彩结构在防伪纤维1内均各自沿条状纤维A的长度方向L延伸。在以下的所有实施例中，防伪纤维均包含具有色彩视觉特征的一个或多个特定色彩结构，每个特定色彩结构在防伪纤维1内均各自沿条状纤维A的长度方向L延伸。这样，得到的防伪纤维的立体的色彩视觉特征就完全区别于印刷油墨得到的平面的色彩视觉特征。尤其，当防伪纤维中还包括沿条状纤维长度方向延伸的激发光阻隔材料时，阻隔材料与特定色彩结构配合使得防伪纤维的色彩视觉特征更加的丰富，比如光角变色，改变入射光的入射角度，得到不同的色彩视觉效果，这是印刷油墨所无法实现的。图3示出了另一种直线形的点线结构的防伪纤维的俯视图，包括六个点2和两条连线3，点2₁只有一个相连端、其与连线3相连，点2₂的两个相连端一个与连线3相连另一个与点2₃相连，点2₃的两个相连端均与两侧的点相连，点2₄的两个相连端一个与连线3相连另一个与点2₃相连，点2₅的两个相连端一个与连线3相连另一个与点2₆相连，点2₆只有一个相连端、其与点2₅相连，相比于图2中点2和连线3彼此交替的点线结构，图3的点线结构具有更丰富的视觉效果(相邻的点可以具有不同的色彩视觉特征)。Fig. 1 shows an integral pseudowire 1 of a dotted structure which is cut along the transverse direction of the strip fibers A. The security fiber 1 comprises two corresponding cutter faces, wherein the strip fibers A are included along the length direction L thereof. A particular color structure that imparts a colored visual feature to a dotted line structure, said color visual feature being a color feature that is directly or indirectly perceived by the human eye. In the production of the strip fibers A, the specific color structure is distributed along the transverse direction of the strip fibers A and extends non-twisted along the longitudinal direction of the strip fibers. Therefore, the specific color structure of the dotted line structure does not have a problem of alignment, and is specific. The color structure runs through the thickness of the dotted line structure to form a stereoscopic effect. The transverse direction here includes a vertical transverse direction perpendicular to the longitudinal direction of the strip fibers and an oblique lateral direction at an angle other than 90 degrees to the longitudinal direction. Fig. 2 is a plan view of the security fiber viewed from one of the cutter faces. The security fiber 1 is linear in its entirety, including three points 2 and two wires 3, and the dots 2 and the wires 3 are alternately arranged (that is, the connected ends of each dot 2 in the dotted structure are connected to the wire 3 ). The security fabric 1 comprises one or more specific color structures having color visual features, each of which extends in the longitudinal direction L of the strip fibers A within the security fibers 1 . In all of the following embodiments, the security fibers each comprise one or more specific color structures having color visual features, each of which extends in the lengthwise direction L of the strip fibers A within the security fibers 1 . Thus, the stereoscopic color visual characteristics of the obtained security fiber are completely different from the planar color visual characteristics obtained by the printing ink. In particular, when the anti-counterfeit fiber further includes an excitation light blocking material extending along the length direction of the strip fiber, the barrier material cooperates with a specific color structure to make the color visual feature of the anti-counterfeit fiber more abundant, such as the color angle discoloration, changing the incident of the incident light. Angle, get different color visual effects, which is impossible to achieve with printing ink. Figure 3 shows a top view of another linear anti-counterfeit fiber of a dotted structure comprising six points 2 and two wires 3, point 2 _{1 having} only one connected end, which is connected to the wire 3, point 2 ₂ the two ends connected to a 3 connected to the other connection point ₂₃ is connected to the two end points ₂₃ are connected to both sides of the point is connected to two points ₂₄ is connected to the other end connected to a connection 3 One is connected to point 2 ₃ , and the two connected ends of point 2 ₅ are connected to the connecting line 3 and the other is connected to the point ₂₆ , and the point ₂₆ has only one connected end, which is connected to the point ₂₅ , compared to FIG. The dotted line structure in which point 2 and line 3 alternate with each other, the dotted line structure of Fig. 3 has a richer visual effect (adjacent points may have different color visual features).
