- Textile and clothing industry is one of the oldest manufacturing industries and is a major contributor in the economic growth of developing countries. However, from past few decades, it has been criticised for its opaque, unsecured and untraceable nature of supply chain. Addressing these challenges, the paper proposes a system approach to introduce an item-centric secured traceability concept to monitor and control manufacturing processes and supply chain activities. In order to implement such secured traceability system, the paper describes the process for manufacturing, encoding and validating an innovative two-factor secured tag based on particle randomness that is printed on the surface of textile. Being micro-sized, the particles are easy to read and validate with pattern recognition. Further, as achieved through an uncontrolled manufacturing process, the randomness is unclonable to produce counterfeit tags. Furthermore, a sequence of experimental analyses has been conducted using various simulated scenarios to verify its applicability. A secured tag can be a low-cost and durable substitute for detachable, unsecured identifiers commercially available in the market.

- Cryptographic tags are an important entity for tracking and authentication of a product in the today's global supply chain. They act as carriers which map the information with physical product. Further, their importance in Textile and Clothing industry has significantly enhanced due to increased counterfeit activities and complex supply-chain networks. In this context, this paper describes various existing cryptography methods and tags, scope for improvement and possible solutions for their use in Textile and Clothing supply-chain traceability.

- Product security is one of the major concerns in the textile industry. Every year, fashion brands suffer significant loss due to counterfeit products. Addressing this, the paper introduces a secured tag for traceability and security of textile products. The proposed tag is unclonable, which can be manufactured using conventional screen-printing process. Further, it can be read using a smartphone camera to authenticate the product and trace its history. Consequently, imparting additional functionality to the textile through surface modification. To validate its applicability, the study experimentally investigates the durability and readability of the developed secured tag using three different binders on polyester and cotton textiles substrates. A comparison is presented with an in-depth analysis of surfaces and binders interaction at different stages of the secured tag lifecycle, i.e. before print, after print, after wash and after abrasion cycles. The methodology and findings of the study can also be useful for other manufacturing domains dealing with the printing process.

Implementing traceability using particle randomness-based textile printed tags
- 2017
-
Konferensbidrag (refereegranskat)abstract
- This article introduces a random particle-based traceability tag for textiles. The proposed tag not only act as a unique signature for the corresponding textile product but also possess the features such as easy to manufacture and hard to copy. It seeks applications in brand authentication and traceability in textile and clothing (T&C) supply chain. A prototype has been developed by screen printing process, in which micron-scale particles were mixed with the printing paste and printed on cotton fabrics to attain required randomness. To encode the randomness, the image of the developed tag was taken and analyzed using image processing. The randomness of the particles acts as a product key or unique signature which is required to decode the tag. Finally, washing and abrasion resistance tests were conducted to check the durability of the printed tag.

- Traceability has gained considerable attention to facilitate monitored production, product recall, safety and reverse supply chain activities, in recent years. Traceability in manufacturing and distribution involves the use of tracking tags which are attached to the products; consequently, the products are tracked by recording the identity of attached tracking tags in the supply chain. In this context, this paper introduces a new yarn coding-based tracking tag which is fully integrated into textile for tracking the textile supply chain. The new tracking tag involves the use of special yarns which act as information carrier and basic unit of the tracking tag. An implementation scenario is discussed to use the designed tracking tag to monitor the production and authentication purposes. Real prototypes of the fully integrated coded yarn based textile tags are demonstrated in woven and knitted structures and analysed under the effect of washing treatments to simulate realistic conditions. Further, an image pattern recognition based algorithm has been introduced and analysed to extract the information encoded in the tag using coded yarns.
