Electrostatic Attenuation Testing machine Test

The electrostatic attenuation performance tester for medical fabrics is used to test the electrostatic attenuation time of samples from peak voltage to 10% after applying 5000 V voltage to textile and clothing, medical fabric materials, nonwovens, composite materials and film materials.

Standard is a professional manufacturer of textile testing equipment, and Electrostatic Voltage Attenuation Tester designed and produced by us has always been one of the best-selling products of the company. When you buy Electrostatic Charge Decay Meter from Standard, we will provide you with professional instruction and later quality assurance service.



operating procedure

1. sample preparation

The sample and standard friction white cloth should be conditioned in a constant temperature and humidity environment.

When the sample has multiple colors, all colors should be rubbed.

If the area of each color is large enough, samples shall be taken separately.

Cut the sample, do dry friction and wet friction respectively, and ensure that all colors are rubbed.

If the front and back of the sample are made of different materials and colors, the rubbing color fastness test should be done on both sides.

Dry and wet rubbing fastness should not be repeated in the same part of the sample.

2. Dry friction

Place the sample flat on the friction instrument covered with sandpaper, make the length direction of the sample consistent with the moving direction of the instrument, fix the sample on the pressure plate, and clamp the sample flat.

Fix the standard friction small white cloth on the friction head, clamp it with a spring clamp, and lightly place the friction head on the sample;

Ensure that the sample does not slip or wrinkle during friction;

The motor shakes the friction arm 10 times at a rate of once per second, so that the friction arm rubs back and forth 20 times;

Remove the standard friction small white cloth and grade it.

3. Wet friction

Completely soak standard friction small white cloth in distilled water;

Take it out and squeeze it in filter paper to make it have a certain moisture content;

The rest steps are the same as the above dry grinding steps;

Result processing

Before grading, use transparent glue to gently rub loose fluff on white cloth.

Use three layers of unused friction white cloth to pad under the friction white cloth to be evaluated, and evaluate the staining grade of the friction small white cloth with reference to the standard staining gray card.

4. Test report

Standard method of reporting

The results of dry friction and wet friction were reported respectively.

If the sample is pretreated or post-treated, report the treatment method.
