Sprinkler test is one of the most frequently used tests in the textile sector. This test is applied by using a special test device to determine the wettability, water repellency and waterproof properties of textile products. These tests are called the Bundesman sprinkler test.

Water permeability of fabrics is the ability of water to pass through the fabric in case of contact with the fabric at a certain angle and with a certain intensity. Water resistance is the property of water penetrating into the fabric surface. Generally, waterproofing of textile products is ensured in two ways. Either fabrics are produced without waterproof properties. Although the fabric is not dark in appearance, the fabric is given a pusher property. Water repellency is the ability of fabrics to resist natural or post-water removal or water absorption. This property is imparted to the fabric by finishing agents which provide a hydrophobic character. Or polyester, polyamide and similar hydrophobic fibers are used.

Briefly, the sprinkling facility determines the water retention of the fabrics, the resistance to water and the degree of surface wetting. In these tests, the ability of the fabric surface to repel water is measured.

For physical tests performed in accredited laboratories, standards issued by local and foreign organizations are complied with. In this context, the following standards are taken into consideration in color sprinkler tests:

• TS EN 29865 Textile products - Determination of water repellency in fabrics - Bundesmann rain - Shower method
• ISO 9865 Textile - Determination of water repellency of fabrics by Bundesmann rain shower test
• AATCC 35 Water resistance: Rain test (Test method 35)
• DIN 53888 Textile test - Determination of water repellency of textile fabrics by rain shower test according to Bundesmann

Laboratories must have a strong technological infrastructure and trained and experienced employees in order to provide quality and reliable results.
