Determines the wear and abrasion resistance of fabrics used in clothing, footwear and industrials. Redesigned UWT features digital controls for accurate cycle counting and timing, improved air injection system for more uniform inflation of the diaphragm used in surface abrasion testing, and a superior clamping mechanism for repeatable specimen tensioning.Tests are run in utomatic mode to obtain definite results of high reproducibility and to lessen the need for operator evaluation of test results. The digital counter eigher counts the number of cycles to specimen rupture or can be preset for automatic shutoff without specimen failure. The user can select the timer mode for accurate countdown of test time while simultaneously counting the number of abrasion cycles.Supplied with surface brasion head, inflated diaphragm method and flex abrasion head, tension and head weights and initial supply of abradents. Fitted with built-in timer and mechanical cycle counter repeatable and reproducible testing is ensured by consistent motor speed providing 120 double strokes per minute of 25mm (1in) stroke length. Accessories are available for conducting frosting, pilling and edge abrasion tests.Pilling tests utilize a special elastomeric pad attached to the specimen holder of the optional Frosting Attachment. The specimen is rubbed with a second elastomeric pad ounted on the upper head as the abradant. Edge and fold abrasion tests expose the seam edge or fold of the specimen to the abradant by mounting the specimen in the optional Edge and Fold Abrasion Clamp.
