Sock Stretch Tester

Technical Breakthroughs
Combines dynamic tensile testing with moisture simulation to evaluate stretch recovery in knitted fabrics. Clamps hold samples at 20–100% strain while a humidity chamber (RH 30–90%) mimics sweat conditions. Strain gauges track elongation at 100 Hz, and thermal imaging detects fiber relaxation post-stretch.

Key Features

• Multi-Axis Testing: Simulates ankle movement via programmable multi-directional stress.
• Real-Time Analytics: Software calculates hysteresis (energy loss during relaxation).

Applications

• Athletic Wear: Ensures compression socks retain shape after 500+ reps.
• Medical: Validates pressure garments for burn victims.
• Fashion: Tests seamless socks for 10,000+ don/doff cycles.

Market Differentiation
Exceeds ASTM D4964 standards with 50% faster testing (30 sec/sample vs. 1 min). A sock manufacturer reduced material waste by 18% by optimizing yarn elasticity.

Sustainability Angle
Identifies over-engineered fabrics, cutting yarn usage by 12% in sportswear.
