Patience and persistence power innovation.<\/p>\n\n\n\n
Since the first industrial revolution, the weaving industry has made significant advances to increase the productivity and efficiency of its machines as well as the quality of the fabric they produce. This has been accomplished through improving the quality of the yarns and increasing digital automation, control and monitoring. Today\u2019s weaving machines are ready for the fourth industrial revolution. However, these advances in weaving have mainly targeted elimination and reducing short-term weaving stops. <\/p>\n\n\n\n
Two long-term downtimes have remained unchallenged: the tying-in process and the drawing-in process. Previously, improvement in tying-in machines targeted knotting automation and knotting speed and diversification of handling different yarn types. While the weavers appreciate the advances in tying-in technology, the weaving process has to be stopped for a long time during the tying-in of ends from the depleted warp beam to the ends from a full warp beam.<\/p>\n\n\n\n
For decades, Charles A. Cannon Professor of Textiles Abdel-Fattah Seyam<\/a> and William Oxenham, the Abel C. Lineberger Distinguished Professor Emeritus<\/a> in the Wilson College of Textiles, have known about this time-draining problem for weavers. These professors have many years of experience in all aspects of yarns and fabrics, including yarn-machine interactions, and have designed and constructed apparatus and equipment for assessing yarn tension. <\/p>\n\n\n\n High-speed weaving machines require frequent tying-in. Stopping high-speed weaving machines frequently for such a long time is a premium. The lack of efficiency impacts the cost and hence the industry\u2019s competitive edge, too. An initial study on time loss during tying-in revealed that the weaving process stopped for three to six hours for approximately 3,000 to 6,000 warp ends, respectively.<\/p>\n\n\n\n Although the problem isn\u2019t a new one for the weaving industry, industry and researchers remained perplexed as time passed. Did they need to stop the weaving machines for so long each time? <\/p>\n\n\n\n No.<\/p>\n\n\n\n Wilson College of Textiles Professors Seyam and Oxenham had a solution. They also had support for a now-patented idea for their non-stop tying-in process. Then came the next step:<\/p>\n\n\n\n \u201cSolutions need resources,\u201d says Seyam, who is also head of the Department of Textile and Apparel, Technology and Management.<\/p>\n\n\n\n With a solution on paper, Seyam and Oxenham sought support. When they learned about the call for proposals from the Walmart Manufacturing U.S. Innovation Fund<\/a> and saw that improving weaving efficiency was one of the research areas included, they submitted what would become a winning proposal to improve weaving efficiency via the development of a \u201cnon-stop tying-in process.\u201d The funding organization awards proposals that can enhance U.S. competitiveness and create more jobs.<\/p>\n\n\n\n
