WIRA Draper

The drape characteristic of nonwovens is important for interlinings and shows its ability to form natural folds.

Test Method

The test allows a circular sample to drape around a support. The cast shadow from the draped sample is assessed and the drape coefficient recorded.

Hydrostatic Head Test Machine

The Hydrostatic Head test method assesses the ability of a fabric to withstand water penetration by measuring the height of a column of water applied to the sample required to effect the water penetration.This provides a rapid indication of product performance.

Test Method

This machine is supplied complete with a variable clamping system that enables complete garments to be tested and the test area to be viewed. Variable controlled time and pressure rise are features. PC output for display of results.

WIRA Run-Test

This test is used to evaluate the run-off characteristics of nonwovens. The run-off is determined as the amount of excess liquid that runs from a sample.

Test Method

Under standard conditions a specified amount of simulated urine is applied to a sample.The nonwoven specimen is placed on a standard absorbent medium on an inclined plane. Run-off liquid is collected by a standard receiver pad at the base of theincline. The WIRA Run-Test instrument forms an inclined plane of 25 ° complete with support for placing the standard receiver pad below the end of the test piece to receive the run-off liquid, as well as dosing equipment to deliver the test liquid to the sample. The timer and balance are available additionally.
