Assigning Spinning versus Sizing Root Causes in High Speed Weaving Faults
Differentiating spinning and sizing root causes requires cross-sectional microscopy and high-speed tensile testing to map size encapsulation against yarn mass variation.
Webtester Abrasion
Rub Resistance
Measurement of the ability of sized yarn to withstand repeated mechanical friction identifies this test value. Results from webtester abrasion indicate how well the protective chemical film will survive the sawing motion of the heddles and reeds. This value acts as a primary predictor for weaveroom performance in heavy linen production.
Testing Action
Small samples of yarn are placed between parallel bars that move back and forth while applying a consistent tension. This motion simulates the thousands of cycles of shed opening and closing that occur inside a modern air jet loom. When the size coating fails, the flax fibers quickly unravel and form fuzzballs that eventually lead to catastrophic breakage.
Data from these sessions help lab managers choose between different grades of synthetic polymers or starch types. Adjusting the humidity during the test ensures the results match the real world conditions of the textile factory floor.
Sizing Selection
Higher scores allow the production department to run looms at faster speeds without increasing the frequency of defects. Reliability in this metric ensures that the yarn remains smooth throughout the entire duration of the weave cycle. This parameter determines the optimal chemical recipe for a specific yarn count.
