Application of UV aging Test Chamber in sunscreen clothing

Sunscreen clothing is a type of clothing specifically designed to protect against UV radiation and is widely used in outdoor activities, outdoor work, and water sports. To ensure that sunscreen clothing can still effectively provide UV protection after prolonged use, UV aging Test Chambers can be used to evaluate its durability and UV protection performance.

Test method

The following are the specific functions and processes of the UV aging Test Chamber in the application of sunscreen clothing:

1. Select sunscreen clothing materials that meet relevant standards, such as textiles with better UV barrier properties. Prepare samples of sunscreen clothing that meet specification requirements, including complete clothing parts or cut material samples.

2. According to relevant standards and specifications, set parameters such as UV radiation source, light intensity, temperature and humidity in the Test Chamber. Ensure that the test conditions can simulate the real UV radiation environment and outdoor climatic conditions.

3. Secure the sunscreen clothing sample on the sample table of the Test Chamber to ensure that the surface of the sample is completely exposed to UV radiation. It can be installed in a stretched or worn state as required.

4. Start the UV aging Test Chamber and expose the sample to simulated UV radiation. Exposure to UV radiation for a certain period of time is carried out according to the set test conditions. At the same time, damp-heat cycling can be selectively performed to simulate the real outdoor environment.

5. Regularly monitor and record the performance changes of sunscreen clothing samples. Appropriate instruments and equipment, such as ultraviolet measuring instruments, Tensile Testing Machines, etc., can be used to measure and record the ultraviolet transmittance, tensile performance, durability and other indicators of sunscreen clothing.

6. Analyze the performance changes of sunscreen clothing samples according to test data and evaluation indicators. Compare the differences between different test samples and evaluate their UV blocking performance, durability and service life.

Through the UV aging Test Chamber, the UV protection properties of sunscreen clothing materials and designs can be evaluated to ensure that they can effectively protect the skin from UV radiation damage after prolonged use. This helps manufacturers and consumers choose high-quality sunscreen clothing and provide reliable UV protection.

Reference standard

The UV aging test of sunscreen clothing can refer to the following industry standards:

1. ASTM D6554: "Standard Test Method for Determination of Transmissivity of Non-Dyed Textile Fabrics, Including UV Penetration"

• ASTM D6554 is a standard published by the American Society for Testing and Materials (ASTM) to measure the transmission properties of textile fabrics, including UV penetration. This standard can be used to evaluate the UV blocking properties of sunscreen clothing materials.

2. AATCC TM183: "Test Method for Transmittance or Blocking of Erythemally Weighted Ultraviolet Radiation through Fabrics"

• AATCC TM183 is a standard issued by the American Association of Textile Chemists and Dyeers and Finishers (AATCC) to measure the ability of textile fabrics to transmit or block erythema-weighted UV radiation. This standard can be used to evaluate the UV protection performance of sunscreen clothing.

Specific application

Specific application cases include but are not limited to the following areas:

1. Outdoor activities: Sunscreen clothing is widely used in outdoor activities, such as mountaineering, hiking, camping, fishing, etc. Through the ultraviolet aging test, the ultraviolet protection performance of sunscreen clothing under long-term outdoor exposure can be evaluated to ensure effective protection of human skin.

2. Water sports: Sunscreen clothing is commonly used in water sports such as surfing, swimming, windsurfing, etc. UV aging testing can help evaluate the durability and protective performance of sunscreen clothing under prolonged exposure to water and UV rays.

3. Construction and Industry: In construction and industry, sunscreen clothing is used as work clothing to protect workers from UV radiation. UV aging testing can assess the UV protection performance and durability of sunscreen clothing in the work environment.

4. Health Care: Sunscreen clothing is also suitable for health care areas such as medical use, nursing facilities and nursing staff. Through the UV aging test, the protective performance and durability of sunscreen clothing can be evaluated to ensure effective UV protection during the delivery of care and services.

NBChao Tip: Depending on specific market needs and requirements, it may also be necessary to refer to other standards and specifications, such as the standards of the international standards organization (ISO). These standards can provide guidance and reference to ensure that the performance of sunscreen clothing meets relevant requirements.
