The AATCC 22 standard, published by the American Association of Textile Chemists and Colorists (AATCC), provides a test method applied to any textile fabric with or without a water-repellent finish. With this test method, the resistance of the fabrics against wetting with water is determined. This standard is particularly suitable for measuring the water repellency (water impermeability efficiency) of finishing treatments applied to fabrics.
The results obtained with the test method described in the AATCC 22 standard are based on the wetting of the fibers, yarns and finishes on the fabric, water repellency and the structure of the fabric.
AATCC has developed over two hundred textile-related standards, including test methods and evaluation procedures. These standards are published annually in the AATCC technical handbook. These standards are designed and updated by volunteer members through research committees. In addition, all industry stakeholders can participate in the standard development process.
AATCC 22 Water repellency: The principle of the spray test is to evaluate the water spray pattern on the surface of a fabric sample under controlled conditions using a visual rating scale.
AATCC 22 Water repellency: spray test and AATCC 35 Water resistance: rain test standards are the two most widely used standards to determine the performance characteristics of textile products such as coats and jackets.
Tests for water repellency, absorbency and resistance are generally based on standards developed by AATCC. AATCC's focus on developing standardized test methods is due to fabric qualities related to fabric wet processing and finishing. AATCC does not develop performance standards for end textiles.
The contact of a fabric designed for raincoats or tents is judged on its ability to keep water out, among other properties. There is a relationship between water and textile materials that is essential for their end use. Water repellency is a condition characterized by the fact that water does not spread on a textile material. This is usually achieved with fabric treated with a substance such as oil, wax or rubber. Spray tester is an instrument that measures the water repellency of a fabric.
With the experience gained over many years, our organization also provides AATCC 22 Water repellency: spray test services to the demanding enterprises within the framework of laboratory services of materials with a trained and expert staff.
