Description

Technical Field

[0001] This utility model belongs to the field of physical performance testing of textiles, and specifically relates to a test device for infrared radiation shielding rate of textiles. Background Technology

[0002] Infrared Shielding Rate (ISR) refers to a material's or object's ability to block infrared radiation, usually expressed as a percentage. It is a key indicator for evaluating the functionality of textiles, crucial for properties such as light blocking, sun protection, and heat insulation. It can be directly used to evaluate the actual performance of textiles in many fields, including high-temperature protective textiles, summer clothing, outdoor textiles, and curtains. Textiles with excellent infrared shielding performance can effectively block infrared energy from solar radiation or industrial heat sources, reducing heat transfer and thus improving wearer comfort and safety, or improving indoor thermal environments and saving energy. However, current domestic and international textile standards systems lack unified and standardized testing equipment and methods for infrared shielding rate.
