Spray test 36

Determination of resistance to surface wetting with spray test

UNI 4920: 2013, AATCC Test Method 22: 2014

Overview

ASK FOR A QUOTATION:

Fabrics-Water-repellency-Spray-test-Branca

The "Spray test 36" allows for water repellency tests on samples of fabrics, namely to determine the ability of a fabric to absorb water, which is in contact with the same, in form of rain.

It is especially suitable for measuring the water-repellent efficacy of finishes applied to the fabrics.

The exact definition of the test method is therefore "resistance to wetting."
Spray test 36 consists of:
  • a sprayer with 19 holes having the same predetermined diameter according to the Standard;
  • a laboratory glass funnel with a predetermined diameter;
  • a circular support inclined 45 to perform the tests on the test tubes;

The distance between the center of the sprayer and the center of the support is fixed as defined by the Standard.

The test is carried out by fixing the tube to the frame so that it is not bent, and then pour 250 mL of water at (20 5) C in the funnel; so you will have a splash in the average length of 25-30 seconds. It then rotates the frame 180 and the test repeated.

For test pieces of ribbed fabrics, such as velvets, please also place the tube on the frame so that it presents the coasts tilted 45 with respect to the flow of water coming down along the fabric itself.
