An invention from NC State textiles researchers could solve a knotty problem in weaving plants: stopping looms to tie in new threads when yarn runs out.<\/p>\n\n\n\n

Researchers Abdel-Fattah M. Seyam and William Oxenham have filed a U.S. patent application for their nonstop tying-in process. Their innovations could boost textile plant efficiency by reducing the time needed to replenish warp threads on a loom.<\/p>\n\n\n\n

\u201cThis work could be a game-changer,\u201d says Dave Hughston, director of continuous improvement for P&A Industrial Fabrications in Roxboro, which has agreed to hold full-scale trials in its plant.<\/p>\n\n\n\n

P&A manufactures high-end specialty products, including an array of paint rollers for Sherwin Williams, branded heel pads for BMW and Mercedes floor mats, and specialty fabrics used in inflatable boats for the U.S. military.<\/p>\n\n\n\n

The company, which employs about 45 workers, dedicates itself to lean manufacturing \u2013 eliminating steps in its production process that don\u2019t add value.<\/p>\n\n\n\n

Nonstop tying-in equipment reduces the time needed to replenish warp threads on a loom. The process involves a tying-in machine (left), an accumulator (center) and the weaving machine (right).<\/figcaption><\/figure>\n\n\n\n

\u201cWe have about 40 looms, and the longest downtime we have comes during the tying-in process, when yarn runs out on the beam and we have stop the loom to tie in new threads,\u201d Hughston explains. \u201cIn our case, that involves using a machine to tie 6,400 knots. Depending on the size of the beam, that means four to eight hours of downtime. Cutting that downtime to one to two hours would be very beneficial.\u201d<\/p>\n\n\n\n

NC State\u2019s research, funded with a grant of $574,000 from the Walmart U.S. Manufacturing Innovation Fund, is part of a five-year effort to improve competitiveness and create jobs.<\/p>\n\n\n\n

\u201cWe estimate that nonstop tying-in could result in a 4 to 6 percent increase in weaving process efficiency,\u201d says Seyam, Charles A. Cannon Professor of Textiles and Alumni Distinguished Graduate Professor in the College of Textiles.<\/p>\n\n\n\n

In spite of improvements in yarn quality and high-speed weaving machines, manufacturers haven\u2019t been able to solve the problem of long stops in production to replenish the warp sheet.<\/p>\n\n\n\n

\u201cTextile looms have been around for 3,000 to 4,000 years, and weavers have wished for hundreds of years for a solution to this issue,\u201d says P&A\u2019s Hughston.<\/p>\n\n\n\n

NC State researchers have tested a prototype of a new accumulator and tail beam support in the Weaving Lab on campus. The next step is finding a machine manufacturer to build full-scale versions, says Oxenham, the Abel C. Lineberger Professor in the College of Textiles.<\/p>\n\n\n\n

After that, full-scale trials can take place at P&A, a frequent corporate partner that welcomed two NC State industrial engineering students for assignments this year.<\/p>\n\n\n\n

\u201cWe always enjoy the cooperation between us and NC State,\u201d Hughston says. \u201cThe combination of the Walmart grant, NC State textile expertise and teaming up with a machine manufacturer to actually make this work is exciting.\u201d<\/p>\n","protected":false,"raw":"\n\n\n\n\n
