Textile waterproof performance testing, also known as water resistance testing, is mainly divided into water penetration resistance (hydrostatic pressure) testing, surface water repellency (spray rating) testing and water repellency test.Under what circumstances is hydrostatic pressure tested? Is it necessary to test the water staining level? Does water repellency test need to be tested at the same time?Commonly used test methods are listed in the table belowWater Resistance Test MethodsTest EquipmentHydrostatic Pressure RatingHydrostatic Pressure Tester GT-C26ASpray RatingSpray Rating Tester GT-C31Water Repellency TestBundesmann Water Repellency Tester GT-C38Water Resistance Test Methods1. Hydrostatic Pressure RatingThe degree to which a fabric resists being penetrated by water. Hydrostatic pressure resistant textiles are a class of fabrics with special functions, which are not only widely used but also rapidly developed, generally used in outdoor sports jerseys, table cloths for family use, mackintoshes and umbrellas for daily use, and swimming suits and diving suits.Hydrostatic pressure test is a common method to assess the water resistance of fabrics. It is based on the principle of hydrostatic pressure on the fabric to indicate the resistance of water through the fabric. Under standard atmospheric conditions, one side of the specimen is subjected to continuously rising water pressure until three seepage points appear on the other side, and the value of the water pressure at the time of the third seepage point is recorded, and this is used to evaluate the waterproof performance of the specimen.The Hydrostatic Pressure Tester GT-C26A evaluates waterproof properties of materials including canvas, coated fabrics, coated fabrics, hood fabric, tarpaulin, rain-proof fabrics and geotextile.StandardsAATCC 127 Option 2, ISO 811, ISO 1420, GB/T 4744, GB/T 9082, FZT 01004 , DIN 53886 , EN 20811, EN 13726-3, EN 1734, BS 2823, WSP 80.6, JIS L1092-7.1.1 Method A2. Spray RatingThe degree to which a fabric surface resists being wetted by water. Also called surface moisture resistance. This method is applicable to all waterproof treated and untreated fabrics, and the measured waterproof result has a great relationship with the fibres, yarns, fabric treatment and fabric structure.Spray rating testis through continuous spraying or dripping water onto the specimen, observe the water staining characteristics of the specimen on the surface after a certain period of time, and compare with various wetting degree samples to assess the waterproofness of the fabric.The Spray Rating Tester GT-C31 measures fabric resistance to surface wetting by simulating rainwater exposure. It sprays distilled water onto specimens positioned 150mm below a 45-degree nozzle. Then contrast and evaluate the specimen surface with the standard cards.StandardsAATCC 22, ISO 49203. Water Repellency TestThe performance of a fabric in resisting the amount of wetting and penetration by water. This method is applicable to any fabric with or without a water repellent finish.The impact water penetration resistance of single or composite fabrics is measured at different speeds of water impact strength. The principle is that the test sample is wrapped around a weighed absorbent paper, the absorbent paper is weighed again at the end of the test and the difference in weight between the two times is the amount of water penetration of the sample.Bundesmann Water Repellency Tester GT-C38 use the Bundesmann method to test the water repellency of fabrics.StandardsGB/T14577, ISO 9865, BS EN 29865, DIN 53888, JIS L1092The evaluation of the water resistance of textiles by the relevant testing organisations is often determined by the user according to the type and use of the textiles. Waterproof performance requirements vary significantly depending on textile applications and quality grades. For instance and different evaluation requirements. As the waterproof and moisture permeability of textiles are often a pair of contradictory properties, the moisture permeability of products with good waterproof performance is relatively poor. At present, products with good waterproof and moisture permeability properties are often the most high-grade products, so they also greatly limit the use of waterproof textiles.\

Flame retardancy testing is a test method to determine the ability of the object under test to delay the continuation, spread and propagation of flame. After years of development, flame retardancy testing has formed a variety of standards, and has become a very important test item in the related industry. This article will introduce several common textile flame retardant test methods, including 45 Degree Flammability Test Method, Horizontal Flammability Test Method, Vertical Flammability Test Method, and other flame retardant test methods.What is Flame Retardant Fabric?Flame retardant fabrics are fabrics that do not burn when exposed to an ignition source, or burn very slowly and extinguish themselves within a certain period of time. This kind of fabric usually undergoes special treatment to make it with flame retardant performance to protect people's life and property safety.Commonly used textile flame retardant materials: permanent flame retardant polyester, modified acrylic, aramid, aramid, polyimide, carbon fibre, glass fibre, pre-oxygenated fibre.Textile Flame Resistance Test Methods and Instruments1.45 Degree Flammability Test mathodThis test method stipulates that the specimen is placed at an angle of 45° (the length of the specimen is at an angle of 45° with the horizontal plane), and the combustion source is ignited on the upper or lower surface below the specimen. The time required for the specimen to burn upwards a certain distance is measured, or the time required for the specimen to burn upwards, the flame retardation time, the flame spread rate, the charred length, the charred area or the number of times the quantity sample needs to be exposed to flame at a certain distance from the lower end of the specimen.

Horizontal Flammability Test MethodThis test method stipulates that the specimen is placed horizontally, ignited at the head end of the specimen, the distance the flame spreads on the specimen is measured and the time required to spread the distance is measured, the rate of burning is calculated and the rate of burning is used to characterise the flame retardancy of the fabric. The horizontal method is mainly used to test the flame retardancy of automotive interior materials.Test Equipment:ISO 3795 Horizontal Flammability Tester GT-C34AMainly used for determining the horizontal burning rate of materials used in the occupant compartment of road vehicles ( for example, passenger cars, lorries/trucks ,estate cars, coaches ), and of tractors and machinery for agriculture and forestry, after exposure to a small flame.StandardsASTM D5132, ISO 3795, FMVSS 302 , JIS D1201, FZ/T 01028, GB/T 8410, GB/T20953, SAE J369, GMW32323. Vertical Flammability Test MethodThe method specifies that the specimen is placed vertically (the length of the specimen is perpendicular to the horizontal line) and the combustion source ignites the specimen below the specimen. The test specimen is tested for the shortest ignition time, renewal time, flame retardant time, flame spread rate, charred length (damaged length), charred area (damaged area) and other indicators related to flame retardancy. This Vertical combustion method is mainly used to test the flame retardancy of textiles for clothing, curtains and other fabrics.Test Equipment:3.1 ASTM D6413 Vertical Flammability Test Chamber GT-C35ATo measuring the vertical flame spread for children’s sleepwear, fabrics, other textile materials or resilient filling materials used in upholstered furniture of textiles.StandardsCFR1615, CFR1616, GB/T 5455, ASTM D64133.2 Vertical Combustibility Tester GT-C35BThis Vertical Combustibility Tester to determine the flammability resistance of vertically oriented fabrics and soft fabric toys.StandardsBS EN ISO 6940, 6941,15025, 14116, GB/T 5456,8746, BS 5438, BS EN 1101,1102, 1103, BS EN 14878, BS 5722, AS/NZS 1249, ISO 100474.

Through the 45 Degree Flammability Test Method, Horizontal Flammability Test Method, Vertical Flammability Test Method, and other flame retardant test methods, we can gain a comprehensive understanding of the combustion characteristics of the materials under fire conditions. When conducting the tests, attention needs to be paid to the requirements of the test samples, the test environment, the test process and the test equipment to ensure the accuracy and reliability of the test results. These test methods can provide a scientific basis for the design of fire performance of products, fire risk assessment and the formulation of fire safety measures.
