Security Tape Pattern Interval Using UV-Fluorescent Yarns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security woven labels face challenges in distinguishing genuine from imitation goods due to limitations in the number of corrective garment-production users, difficulty in identifying ultraviolet-fluorescent yarns, especially when colored or integrated into complex patterns, and the need for custom sizes and shapes, which restricts their effectiveness and scalability.
Innovation Solution
A process for manufacturing a security tape with a specific pattern interval that uses colorless ultraviolet-fluorescent yarns woven in a specific color order, allowing identification under ultraviolet and/or infrared radiation, enabling the tape to be cut into labels of various widths and sizes, and incorporating infrared-fluorescent yarns for broader identification capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultraviolet-fluorescent yarns are interwoven into the center of woven label, then security identification capability is improved, but the yarns are sunk into the label making judge operation difficult and complex beautiful patterns are compromised
Solution Approach 1:
The patent applies local quality by placing ultraviolet-fluorescent yarns in specific local positions (first and end rows) rather than uniformly throughout the label. This localized placement ensures security identification capability while maintaining visibility and not sinking into the complex patterns in the center of the label.
2Ease of operation
If ultraviolet-fluorescent yarns are interwoven into the periphery of woven label, then judge operation is improved, but the number of corrective garment-production users decreases to less than ten companies
Solution Approach 1:
The patent achieves universality by making the security label applicable to a wide range of garment-production users (more than one hundred companies). The standardized first and end row configuration with ultraviolet-fluorescent yarns can be universally applied across different label sizes and designs, making it versatile for numerous customers rather than limited to a few.
3Adaptability or versatility
If red, blue and/or green ultraviolet-fluorescent yarns are utilized, then the number of corrective garment-production users must greatly increase, but it is hard to judge whether chromophore is blue or green and distinction becomes difficult when brightness lowers
Solution Approach 1:
The patent utilizes color changes by employing ultraviolet-fluorescent yarns that exhibit different chromophores (red, green, blue) under ultraviolet irradiation. These color changes enable identification and distinction of different yarn types, allowing for accurate chromophore judgment even when the brightness is low or the ground weave is dark.
4Adaptability or versatility
If trademark-showing label is different in size for every kind and quality of garments, then customization capability is improved, but it is indispensable to determine exact numbers and interweave position of every ultraviolet-fluorescent yarns during warping operation
Solution Approach 1:
The patent applies segmentation by dividing the label into distinct sections with ultraviolet-fluorescent yarns placed in standardized first and end rows. This segmentation approach allows different label sizes and configurations to be customized while maintaining a consistent security feature structure, simplifying the warping operation compared to determining exact positions for every yarn individually.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for the production of security labels that can be easily identified by radiation, effectively distinguishing genuine from imitation goods, even in complex patterns and varying sizes, and enables mass production for multiple customers without additional equipment, enhancing market reach and sales.
Implementation Method 1
at least two kinds of ultraviolet-fluorescent yarns with different chromophore, which are interwoven into the tape body in parallel with other yarns... identified by irradiation of ultraviolet rays
Implementation Method 2
identified by irradiation of both ultraviolet and infrared rays

AI summary
In a process for manufacturing to a tape with specific pattern interval, there are utilized at least two kinds of ultraviolet-fluorescent yarns with different chromophore, which is spun out of dope kneaded with a fluorescent material. When ultraviolet-fluorescent yarns and colorless yarns are wound around a warp beam or drum with or without infrared-fluorescent yarns, the ultraviolet-fluorescent yarns are arranged repeatedly in specific color order in the traverse direction during the warping operation. In the process, these yarns as the warp are also woven into a double-wide textile with a wide loom.
