Water Repellency Tester

Water Repellency Tester measures the resistance of fabrics to wetting by water.  B-Tex Engineering offers you Water Repellency Tester which is of high quality and reliable.

Water Repellency Tester is used to check the water repellency of the fabric by spray test in textile testing laboratory. Suitable for Table cloth, tapestry, flooring material fabric manufacturer or processors.

Water repellency test method is applicable to any textile fabric, which may or may not have been given a water-repellent finish. It is very necessary for a manufacturer to test the water repellency ability of the fabric.  This method is especially suited for measuring the water-repellent efficacy of finishes applied to fabrics.

The water repellency ability of the fabric is tested with spray test. The Evaluation of the test is visual appreciation of the surface of the fabric (number of absorption points on the surface). It is very important to test the repellency of a garment worn in foul weather conditions. The more the repellency more comfortable the fabric will be during use. The repellency tends to decrease during washing, so a re-impregnation of a water repellent product is advised.

 

 

Features of Water Repellency Tester:

  • The tester is suitable for measuring the water-repellent efficiency of finishes applied to fabrics, particularly plain woven fabrics.
  • Evaluation is accomplished by comparing the wetted pattern with pictures on a standard chart.

How Water Repellency Tester Works?
 
Before testing is carried out the specimen shall be conditioned for at least 24hours in the standard atmosphere. Water sprayed against the taut surface of a test specimen under controlled conditions produces a wetted pattern whose size depends on the relative repellency of the fabric.

  • To carry out the test, first of all fasten the test specimens securely in the metal hoop of the water repellency tester so that it represents a smooth wrinkle free surface and place it face up on the tester.
  • Adjust the metal hoop so that the centre of the spray coincides with the centre of the metal hoop. Later pour 250 ml of distilled water at normal temperature into the funnel and spray the whole quantity on the test specimen for a period of 25 - 30 sec.
  • Now detach the metal hoop from the stand. Confirm whether water had penetrated to the back of the test specimen. With the face side of the test specimen down, hold the metal hoop by one edge and tap the opposite edge lightly once against the table.
  • Then rotate it 180°C and similarly tap again once on the point previously held to remove any excess water drop.
  • The final step is to compare the wetting of the test specimen with a photographic rating standard and grade it accordingly.
