The Textile Center has two physical testing labs that house over $1 million worth of equipment that make it possible to perform a wide variety of physical testing on fibers, yarns, and fabrics.

  • Fibers can be singled out and analyzed for size, breaking strength, elongation, staple length, and other attributes.
  • Yarns may be processed through the latest generation Uster UT3 and UT5, Tensorapid and Tensojet machines for a thorough look at the quality of your product. Yarns may also be tested for shedding, turns per inch, and friction in this lab.
  • Fabrics can be analyzed for content and construction by breaking them down into yarn or fiber form and running tests or they can be tested in fabric form for ball burst, tear strength, pilling, shrinkage and more. In addition we can analyze the fabric and determine the weave or knit patterns used to produce the fabric.

Please contact the Physical Testing Lab to discuss your physical testing needs.
