  • Publication number: 20230410128
    Abstract: A method for managing a genuine fabric with blockchain data comprises the following steps: receiving at least one image of a genuine fabric photographed by a computing device, wherein the image contains at least one anti-counterfeiting texture generated during a manufacturing process thereof, and the computing device performs image analysis on the anti-counterfeiting texture to obtain at least one hash value; forming an smart contract with a text serial number corresponding to the genuine fabric and the hash value by one of a plurality of nodes in a blockchain through the computing device, and launching the smart contract to the nodes; and providing a key to at least one of a fabric production end and a brand sales end, wherein after the smart contract is signed, a non-fungible token which is associated with the genuine fabric is minted at one of the nodes in the blockchain.

  • Patent number: 11702775
    Abstract: A method for forming an anti-counterfeiting feature during knitting of a fabric and a fabric thereof, the fabric is knitted with at least one first yarn, a part of the fabric includes a plurality of featured yarn loops formed by a second yarn, the featured yarn loops constitute an anti-counterfeiting feature, the anti-counterfeiting feature can be directly observed from one side surface of the fabric, the second yarn is formed by twisting at least two sub-yarns with different shades, and shades of the at least two sub-yarns and the first yarn are different from each other, and a shade of the featured yarn loops displayed on the side surface is random. Accordingly, the randomness of yarn twisting makes the anti-counterfeiting feature difficult to be replicated, thereby preventing unscrupulous manufacturers from counterfeiting the fabric.

  • Patent number: 11505882
    Abstract: The invention provides a system for performing dynamic production and knitting machine work management comprising a production demand management unit, an advanced scheduling management unit, a cloth pattern storage unit and a manufacturing execution unit. The production demand management unit receives at least one production demand data. The advanced scheduling management unit generates a production scheduling data according to working conditions of a plurality of knitting machines and the production demand data. The cloth pattern storage unit stores a plurality of knitting machine work setting data. The manufacturing execution unit controls each knitting machine to extract one of the plurality of knitting machine work setting data from the cloth pattern storage unit based on a production cloth pattern data. The knitting machine work setting data is forcibly deleted by the knitting machine when a knitting number meets a set value defined by the knitting number limiting data.

  • Patent number: 6255570
    Abstract: A vessel-shaped flute has a body and a captive cap. The cap is pivotally attached to the body with a pivot pin. A through hole is defined through the pivot pin. Consequently, the cap can cover the mouthpiece and all of the finger holes when the vessel-shaped flute is not in use. Protection is provided to the mouthpiece and finger holes to prevent them from being damaged or getting dirty. In addition, a cord can be threaded through the through hole. The user can wear the vessel-shaped flute as a necklace. The use and the decorative effect of the vessel-shaped flute are improved.
