Detection background
The retroreflective properties of retroreflective fabrics are based on the optical principle of applying glass beads to the fabric and using the optical principle of refraction and reflection of light in the glass beads before returning. Even if the reflected light mostly returns to the direction of the light source in the direction of the incident light.
It has a strong cloth base, and after being sewn to other fabrics and substrates, it has a very obvious effect on improving the wearer's visibility at night or in poor sight conditions. Textile retroreflective fabric retroreflective performance testing can measure the retroreflective performance of import and export retroreflective fabrics with a single retroreflective property.
Zhongke Testing Environmental Reliability Experiment Center has the ability to test the reliability performance of various textile raw materials and products, and provides professional retroreflective fabric retroreflective performance testing services for textiles.
TEST PRINCIPLE
sample is measured in a calibrated retroreflection coefficient measuring instrument, and then the retroreflection coefficient is measured again after each relevant physical test. Based on the measured retroreflection coefficient, the retroreflection performance of the sample is comprehensively evaluated.
