Water Absorption Tester for Shoe Insole Absorption & Desorption Test UP‑4021
Product Overview
The UP-4021 Water Absorption Tester is professional footwear laboratory test equipment for evaluating water-absorbing and water-desorption performance of shoe insole materials.
It simulates real-life walking conditions: test specimens are mounted on a damp base plate and undergo repeated flexing under defined pressure. After preset test cycles or test duration, users calculate water absorption (WA) and water desorption (WD) values to assess material performance.
This tester complies with GB/T20991-2007 Clause 7.2 for footwear safety-testing laboratories and footwear material quality-control workshops.

Function
|
1.Simulate walking flexing condition of shoe insoles under specified pressure
2.Test material water absorbing property (WA) and water desorption property (WD)
3.Two test modes: counting mode and timer mode; real time display of running status
4.Automatic stop upon completion of preset cycles or time; manual jog and homing function
5.Pump switch for upper water tank water filling, flow adjustable

Test Principle:
Fix the cut in-sole specimen between stationary fixture and movable fixture.
The brass drum performs reciprocating rolling-flexing over the wet base-plate to simulate repeated bending of shoe insoles during human walking.
Continuous water flows onto specimen surface.
After test completion, weigh specimen to calculate water-absorbing property WA; then condition specimen for 24 hours and re weigh to obtain water-desorption property WD.
Applications:
Quality-control laboratory for safety footwear, work-shoes and casual-shoes manufacturers
Material R&D lab for shoe insoles, insock, footwear textile and synthetic leather
Third-party footwear testing institutes complying with GB/T20991-2007 standard
