DR-T101 Multi-Station Martindale Abrasion & Pilling Tester
The DR-T101 applies precision multi-directional Lissajous motion to evaluate the wear resistance, pilling propensity, and surface fuzzing of woven, knitted, non-woven, and coated upholstery fabrics. Engineered for high-throughput commercial testing labs conforming strictly to ISO 12947, ISO 12945-2, and ASTM D4966.
Quick answer: Choose a Martindale tester based on daily sample throughput (4, 6, 8, or 9 stations), dual-mode stroke switching (60.5 mm abrasion vs. 24 mm pilling), and certified loading weights (9 kPa apparel vs. 12 kPa upholstery)—not cycle counter capacity alone. Confirm individual station counting and standard abradant tooling before ordering.
What a Martindale Evaluation Delivers
End-Point Yarn Breakdown (Rubs)
Specimens are inspected at defined rub intervals until thread breakage occurs: 2 yarns severed for woven fabrics, 1 loop severed for knits, or complete pile destruction in velour.
Gravimetric Mass Loss (mg)
Determines wear kinetics by weighing samples before and after specified cycle stages (e.g., 5,000 or 10,000 rubs). Essential for coated materials and synthetic non-wovens.
Pilling & Fuzzing Grade (1 to 5)
Using the modified 24 mm Lissajous figure, fabrics rub against identical material. Surface balling is graded against standard photographic assessment cards from Grade 1 (severe) to Grade 5 (no change).
Standard Operating Procedure for Reliable Martindale Runs
Abrasion cycle repeatability requires strict control of sample mounting tension, foam backing resilience, abradant condition, and Lissajous symmetry.
Precision Specimen Punching
Cut Ø38 mm circular specimens for abrasion holders or Ø140 mm specimens for abradant tables using dedicated disc die punches. Avoid frayed edges that distort clamping planarity.
Standard Backing Foam Control
Insert certified polyurethane foam (density 30 kg/m³) behind the specimen. Foam degrades under pressure; replace foam discs after every single test run as mandated by ISO 12947-1.
Pressure Weight Application
Apply calibrated loading weights: 9 kPa for general clothing fabrics, 12 kPa for commercial upholstery, or 415 g for pilling tests. Ensure spindles sit perfectly vertical in drive guides.
Periodic Inspection & Auto-Stop
Program incremental cycle thresholds into the touchscreen PLC. The machine pauses at preset checkpoints for optical inspection under 8x magnification without resetting master counts.
Lissajous Verification Protocol: The Lissajous pattern must produce 16 elliptical rubbing curves to form a complete closed figure (60.5 ± 0.5 mm × 24.0 ± 0.5 mm). Periodically verify using the supplied tracing stylus and chart paper.

Choose Martindale for Multi-Directional Surface Abrasion
Martindale simulates gentle multidirectional wear and seating friction; other instruments evaluate linear friction, tear, or snagging.
Martindale · DR-T101
Simulates multidirectional planar rubbing and pilling on woven, knitted, and upholstery fabrics using standard Lissajous geometry.
Wyzenbeek Tester
Applies linear back-and-forth oscillating rubbing over a curved drum per ASTM D4157. Primarily specified in North American contract upholstery.
Fabric Tensile Machine
Measures grab and strip breaking strength (ASTM D5034 / D5035) and tear resistance under progressive static uniaxial load.
Three-Seat Sofa Tester
Evaluates full-scale mechanical frame fatigue, cushion resilience, and seam durability on finished furniture units.
Control the 6 Major Causes of Invalid Martindale Results
Re-using Worn Backing Foam
Polyurethane backing foam loses compression elasticity during prolonged runs. Re-using foam softens the backing, artificially delaying thread breakdown.
Uneven Mounting Tension
Wrinkled or overtightened fabric in the holder ring causes localized stress concentration, resulting in premature localized hole formation.
Worn or Contaminated Wool Felt
Woven wool abradant collects fiber dust and loose pills. Failure to clean or replace abradant cloth alters the coefficient of friction substantially.
Distorted Lissajous Geometry
Mechanical wear or play in internal drive gears distorts the 16-rotation figure-8 curve into an asymmetrical oval, yielding non-compliant rubbing speeds.
Unconditioned Testing Climate
Fabrics (especially cotton, wool, and rayon) absorb room moisture, changing abrasion resistance; always test in a conditioned 20 ± 2°C, 65 ± 4% RH lab.
Subjective Visual Assessment
Pilling evaluation must occur inside a standardized light booth (D65 light source) at a 45° viewing angle using certified reference photographs.
