Quantifying Structural Shear Resistance and Tear Strength Losses under Industrial Cross-Linking Routes
Industrial cross-linking locks flax yarn mobility, driving tear strength losses up to forty percent while restricting structural shear resistance.
Hysteresis 2HG5
Shear Recovery
Mechanical testing of fabric elasticity under shearing forces identifies how much energy is lost when the material returns to its neutral position. The hysteresis 2HG5 measurement is part of the Kawabata Evaluation System and specifically records the width of the shear torque at an angle of five degrees. This value quantifies the internal friction between the flax yarns as they slide against each other.
High values indicate a fabric that is slow to recover from deformation.
Energy Loss
Internal resistance within the linen weave prevents the cloth from snapping back instantly after being twisted or bent. A high hysteresis 2HG5 value suggests that the finish or the natural stiffness of the flax is inhibiting movement. This property affects the overall hand of the fabric, often making it feel sluggish or heavy.
Tailors use this data to predict how well a linen jacket will hold its shape over the course of a day.
Deformation Resistance
Friction between the warp and weft yarns at their crossing points determines the magnitude of this parameter. When hysteresis 2HG5 is kept within a specific range, the fabric exhibits a crisp but resilient character. If the value is too high, the material may suffer from permanent bagging at the elbows or knees of garments.
Controlling this mechanical property is essential for producing high-performance linen textiles that meet international quality benchmarks.
