1. Purpose and Scope
This test method applies to any fabric with or without a water-repellent or water-repellent finish. This standard can be used to measure the impact water penetration resistance of fabrics and predict the rainwater penetration resistance of fabrics. It is especially suitable for measuring the penetration resistance of clothing fabrics.
The results of this test method depend on the water-repellent properties of the fibers, yarns, fabric structure and finishing in the fabric.
2.Principle
Place a weighed piece of absorbent paper behind the pattern, spray a certain volume of water onto the taut surface of the pattern, and then reweigh the absorbent paper to determine the water permeability and, therefore, thewater permeability of the specimen. .
3. Instruments and materials
a. Impactwater permeability tester
b. Type I tester
d. AATCC white absorbent paper
f. Balance, accuracy 0.1g
4. Testing methods
b. Inject 500ml ± 10ml of distilled water, deionized water or reverse osmosis water at 27°C ± 1°C into the funnel of the tester, and spray the water onto the sample. When pouring water into the funnel, do not create a vortex in the funnel (you can stop the vortex flow by fixing a small blade in the funnel and extending to the side).
5. Evaluation
Calculate the increase in weight of the absorbent paper and report the average result for the three specimens. The test value or average value of a single sample is greater than 5.0g, and can be reported as +5g or >5.0g.
6. Report
a. Report each measurement and average. For values greater than 5.0g, report as +5g or >5.0g.
b. Report test methods and instruments used.
