What is the purpose of the bacterial resistance test?

Detects color fading in fabrics
Evaluates bacteriostatic activity
Assesses fire safety in textiles
Measures water resistance of fabrics

The correct answer is: Evaluates bacteriostatic activity

The purpose of the bacterial resistance test is to evaluate bacteriostatic activity in materials, particularly textiles. This test determines how well a fabric can inhibit the growth of bacteria. In environments where hygiene is paramount, such as hospitals or kitchens, textiles that possess bacteriostatic properties can help reduce the spread of harmful bacteria and infections. While other tests assess different properties of fabrics—such as detecting discoloration from light exposure, evaluating fire resistance, or measuring water repellency—they do not specifically focus on bacterial growth inhibition. Evaluating bacteriostatic activity is especially important for ensuring that fabrics used in healthcare or high-contact areas maintain a safe and sanitary environment.
