Textiles Airflow Resistance Tester
The textile airflow resistance tester is used to determine the anti-penetration properties of ordinary fabrics and medical protective masks to airflow at a constant flow rate . It is mainly used for the determination of air penetration of textiles ,cotton, and space cotton. The tester is one of the important means to identify the comfort and hygiene of clothing textiles, especially medical textiles.
Application
(1) Textile Fabrics: Evaluation of airflow transmission through woven and knitted fabrics.
(2) Cotton and Nonwoven Materials: Testing of cotton, nonwoven fabrics, and related sheet materials.
(3) Medical Face Masks: Measurement of airflow resistance or differential pressure under the applicable mask test method.
(4) Medical Protective Masks: Evaluation of relevant airflow resistance characteristics, subject to the specified test procedure and equipment configuration.
(5) Respiratory Protective Products: Potential use for selected airflow resistance measurements when the required flow conditions, specimen fixture, and test method are supported.
(6) Textile Research and Development: Comparison of airflow characteristics across different fabric structures and material compositions.
(7) Quality Control: Routine inspection of fabric and mask materials during production and laboratory evaluation.
