In industries where protective clothing is essential, ensuring the garments' water resistance plays a crucial role in determining their durability and effectiveness. The Spray Rating Tester For Protective Clothing GT-C31 is a vital tool in evaluating the water repellency of protective fabrics. It simulates real-world conditions by spraying water onto textile samples to assess their surface wetting resistance. This article will explore the importance of water repellency testing in protective clothing and provide an in-depth overview of the Spray Rating Tester GT-C31.

Importance of Water Repellency in Protective Clothing
Protective clothing is widely used in sectors such as healthcare, firefighting, industrial work, and outdoor professions where exposure to water, chemicals, and hazardous substances is frequent. The ability of the fabric to repel water is critical because it ensures the wearer's safety by keeping harmful liquids at bay. The Spray Rating Tester GT-C31 provides an efficient method for determining how well fabrics perform in preventing surface wetting, which is especially important for garments exposed to rain or chemical splashes.

Understanding the Spray Rating Tester GT-C31
The Spray Rating Tester GT-C31 is designed specifically to simulate light rain conditions, allowing manufacturers and quality control professionals to measure fabric performance in repelling water. The tester uses a precise method to evaluate surface wetting by spraying water on a sample fabric at a controlled angle and height, as specified in international standards.


Step-by-Step Process of Spray Rating Testing
To understand how the Spray Rating Tester GT-C31 works, let’s break down the test procedure into its key steps:

Step 1: Sample Preparation
Begin by preparing a 180mm x 180mm textile sample. The textile should be representative of the material used in protective clothing to ensure accurate results. Once ready, the sample is installed on the fixture to secure it in place for testing.

Step 2: Securing the Sample
The fixture with the textile sample is then fixed on the 45° test station. This angle ensures that water is sprayed in a manner that mimics natural rain hitting the fabric surface.

Step 3: Funnel and Baffle Placement
A test funnel is placed in the fixed ring above the fixture, and a baffle plate is positioned in the center of the funnel. The baffle ensures that the water is distributed evenly across the textile sample during the test.

Step 4: Measuring Distance
Next, measure the distance between the bottom of the funnel and the sample surface. The prescribed distance is 150mm, but this height can be adjusted based on specific testing requirements.

Step 5: Water Application
Pour 250ml of distilled water into the funnel. The spray time is crucial and should fall between 25 and 30 seconds to ensure consistent results. The controlled flow rate replicates rain conditions that the protective clothing may encounter in the real world.

Step 6: Evaluation of Results
Once the test is completed, remove the textile sample from the fixture and compare it against the standard rating cards. These cards help in assessing the water repellency of the sample based on the degree of surface wetting observed.

Why Choose the Spray Rating Tester GT-C31?
