Spray Water Repellent Tester Spray Test Method AATCC22 أداة الاختبار –

The spray water repellency tester is a testing equipment independently developed and produced by qisnun Precision Mechanical and Electrical Technology Co., Ltd. It is simple and portable, and the testing procedure is relatively simple, which makes this standard particularly suitable for factory products. control. Since this standard cannot measure the penetration of water droplets into fabrics, it is recommended not to use this standard to evaluate the rain penetration performance of waterproof fabrics.

The test results of this standard are related to the initial water-repellent and wetting properties of fibers, yarns and fabrics, and have little to do with the structure of the fabric.

The AATCC22 standard is applicable to any textile fabric, whether or not it has been treated with water-repellent properties. This standard makes it possible to determine the water resistance of fabrics and is particularly suitable for textiles treated withec water-repellent properties, particularly plain fabrics.

Test method:

(1) Fix the 180 X 180 mm test sample firmly to a ring with a diameter of 152 mm. Make sure the surface is smooth and free of wrinkles.

(2) Place the ring with the tissue on the test instrument holder so that the center of the nozzle is aligned with the center of the ring.

(3) Make the deformation direction of the fabric follow the direction of the water droplets flowing on the surface of the fabric, add 27±1℃, 250ml water into the funnel of the funnel test instrument and let it finish. spray in 25-30 seconds and avoid contact with the funnel when adding liquid. The movement of the funnel changes the relative position of the nozzle to the tissue.

(4) Spraying time should be controlled at 25-30 s, otherwise small holes should be checked pto see if they are enlarged or blocked.

(5) Hold one side of the ring, tap it with a hard object on the opposite side of the ring and face the test sa Approach the object, then turn the ring 180 degrees and repeat the above action once.

Evaluation level:

(1) 100 points: The upper surface is not wet with water;

(2) 90 points: There is a small amount of water on the upper surface, irregular staining or wetting;

(3) 80 points: The upper surface is wet when exposed to water;

(4) 70 points: Entire upper surface is partially wet Wetting;

(5) 50 points: The entire upper surface is completely wet;

(6) 0 points: The entire upper surface is partially wet and the surface is leaking.

As an enterprise integrating R&D, manufacturing, sales, training and service, Shanghai Fanbiao Textile TestingTechnology Co., Ltd. is committed to continuously providing more testing instruments to the market and providing textiles, long-term testing. instruments for leather, combustion, automobile interior materials, environmental climate aging, masks, etc. can also accept non-standard customizations. Targeted testing can be carried out according to customer requirements before purchase to ensure that the purchased instruments are suitable.
