Tearing Strength Tester is a consistent tool useful to determine the tearing strength of fabrics, plastic films, and similar materials. Tearing Strength Tester is the tensile force required to rupture a pre-slit sample under controlled test conditions. The Tearing Strength Tester works on the principle of measuring the Internal tearing resistance, which is the force perpendicular to the plane of the fabric required to propagate a single-rip or tear of a defined length from a cut in the fabric when a sudden force is applied. The force required to continue a slit previously cut in a fabric is determined by measuring the work done in tearing the fabric through a fixed distance. The apparatus consists of a pendulum carrying a clamp which is in alignment with a fixed clamp. The pendulum is in raised, starting position with maximum potential energy. The tear force is computed from scale reading and pendulum capacity. Tearing Strength Tester is used to determine the average force in grams per sample required to propagate tearing through a specified length of textile or non rigid cloth. Two sample are cited, a rectangular type and one with a constant radius testing length. The tester is equipped with a pendulum that applies the force.

Water Repellency Tester

Water Repellency Tester

Size of test specimen 180 x 180 mm square.
Rate of water spray 250 ml in 25 to 30 seconds.

The estimation of the test involves visual appreciation of the surface of the fabric (number of absorption points on the surface). The repellency of a garment worn in foul weather conditions is very important. The Spray Test method is used for determining the resistance of any fabric, which may or may not have been given a water resistant repellant finishing surfacing wetting by water. A good repellency will increase the comfort during use. The repellency tends to decrease during washing, so a re-impregnation of a water repellent product is advised. The Test is especially suitable for measuring the water-resistant or water-repellent efficiency of finishes applied to fabrics particularly plain-woven fabrics. It is not intended to predict the rain penetration resistance of fabrics, since it does not measure penetration of water through the fabric. Before testing is carried out, the specimen is conditioned for at least 24hr in the standard atmosphere for testing textiles. The Spray rating is determined by comparing the appearance of the specimen with AATCC & ISO Spray Test Rating Chart.
