怎样辨别真假防晒衣

Core Viewpoint - The recent exposure by CCTV's "Financial Investigation" program revealed that some sunscreen clothing does not effectively block ultraviolet (UV) rays and fails to meet national standards, raising concerns about the quality and effectiveness of these products [1] Group 1: Sunscreen Clothing Standards - Sunscreen clothing is defined as garments made from textiles with UV protection capabilities, primarily functioning by absorbing or reflecting UV rays to reduce their penetration [1] - According to national standard GB/T 18830—2009, a product can be labeled as "UV protective" if its Ultraviolet Protection Factor (UPF) is greater than 40 and the long-wave UV (UVA) transmittance is less than 5% [1] Group 2: Choosing Qualified Sunscreen Clothing - The State Administration for Market Regulation advises consumers to check label information for UV protection functionality and UPF values, with UPF 40+ being the minimum standard and UPF 50+ offering better protection [2] - Fabric density plays a crucial role in UV protection; thicker and denser materials are recommended for better effectiveness [2] - Light-colored fabrics generally reflect more visible light, reducing heat absorption and providing a cooler wearing experience compared to dark colors [2] Group 3: Identifying Genuine Sunscreen Clothing - To distinguish genuine sunscreen clothing, consumers should examine the label for complete information, including national standard numbers and UPF values, and request third-party testing reports if necessary [2] - The choice of fabric and craftsmanship is essential; opting for original yarn-type sunscreen clothing and avoiding low-density synthetic fibers can enhance comfort and effectiveness [2] - Testing the fabric's light transmittance and breathability can help assess its protective qualities, with less light transmission indicating stronger UV protection [2] - Consumers are advised to avoid products without proper labeling and be cautious of exaggerated claims regarding high-tech materials [2][3]
