Solar rays can be roughly divided into visible light and invisible light. Visible light refracts the light (spectrum) of purple, blue, green, green, yellow, orange and red through the prism. The light outside the red light is called infrared light, or infrared light, when the wavelength in the spectrum ranges from 0.75 to 1000 microns. Infrared ray belongs to the category of electromagnetic wave and is an electromagnetic wave with strong thermal effect. The wavelength range of infrared rays is very wide. People divide infrared rays in different wavelength ranges into near infrared, mid-infrared and far infrared regions. Electromagnetic waves with corresponding wavelengths are called near infrared, mid-infrared and far infrared. Far infrared ray is a kind of ray. As far infrared ray is close to the vibration frequency of cells and molecules in the human body, it is beneficial to eliminate blood vessel hoarding and harmful substances in the body after penetrating into the body, and has the functions of activating tissue cells, preventing aging and strengthening immune system. Any environment above zero degree (273.15 ℃) emits infrared rays of varying degrees everywhere, which is called heat ray in modern physics. The indexes of far infrared radiation energy strength include radiation power and radiance, but in practical application, emissivity is often used to characterize it. Far infrared emissivity refers to the ratio of the far infrared radiation intensity of the test sample to the far infrared radiation intensity of the black body at a certain temperature within a wavelength interval. In recent years, more and more fabrics with far infrared properties have been marked on the market. But the performance varies greatly. Wenzhou fangyuan instrument co., ltd. has developed FFZ412A far infrared emissivity tester according to the requirements of GB/T301272013 Textile Far Infrared Performance Testing And Evaluation, which can conveniently provide reliable and relatively high data for the research and development and testing of these products.
Uses: Used for measuring far infrared properties of various textile products, including fibers, yarns, fabrics, nonwovens and their products by far infrared emissivity method. Compliance with standards: GB/T30127 4.1 Determination of Far Infrared Emissivity, etc.
