\n 1. Purpose and scope<\/p>\n
\n 1.1.<\/p>\n
\n This method works on any fabric with or without a water-repellent finish. <\/p>\n
\n This standard can be used to measure fabric <\/p>\n
\n Impact water penetration resistance can be used to predict the permeability of fabrics to rainwater. <\/p>\n
\n Especially suitable for measuring the penetration resistance of clothing fabrics<\/p>\n
\n \tsex. This instrument can give different intensities of impact water and can measure the water resistance of single-layer fabrics or composite fabrics<\/p>\n
\n \tsex. <\/p>\n
\n 1.2. The results of this test are related to the water-repellent properties of fibers, yarns, and fabric structures in the fabric. <\/p>\n
\n
\n
\n 2. Principle<\/p>\n
\n
\n 2.1. Spray water onto the surface of the sample for 5 minutes, place a weighed absorbent paper behind the sample, and then weigh the sprayed absorbent paper to measure the water permeability. <\/p>\n
\n
\n
\n 3. Equipment and materials<\/p>\n
\n 3.1.AATCC<\/p>\n
\n Rain tester<\/p>\n
\n 3.2. White AATCC absorbent paper<\/p>\n
\n 3.3. Distilled or deionized water<\/p>\n
\n 3.4. Balance, accurate to 0.1g<\/p>\n
\n
\n 4. Sample<\/p>\n
\n 4.1. Take at least three samples, each 20X20cm. The sample and absorbent paper were placed in a standard atmosphere to condition the humidity for at least 4 hours before testing. <\/p>\n
\n
\n 5.Process<\/p>\n
\n 5.1. Place a 15.2cmX15.2cm standard absorbent paper behind the sample, and weigh the standard absorbent paper to the nearest 0.1g. Clamp the specimen to the specimen holder on a vertical rigid surface. The sample is placed in the middle of the spray, 30.5cm away from the nozzle. Spray the 27\u00b11\u00b0C water flow directly onto the sample horizontally for 5 minutes. After spraying, carefully take out the absorbent paper and weigh it quickly to the nearest 0.1g. <\/p>\n
\n
\n 6. Rating<\/p>\n
\n 6.1. Calculate the increase in weight of the absorbent paper during the 5-minute spray time, and average the three results. <\/p>\n
\n
\n 7. Report<\/p>\n
\n 7.1. Report averages. If it is greater than 5.0g, report it as +5.0g or >5.0g. <\/p>\n
