When we wear masks, if the earloop are too long or too short, we need to improve the earloop. If you wear it by yourself, the earhook is too long and stick to the long part with tape; or tie a knot on the earloop; pay attention to the size when buying, and choose the right size. What if earloop are purchased in large quantities? How to judge the quality of earloop in large quantities?
Sampling and testing: After purchasing in large quantities, the first thing to do is to test the earloop, elasticity, material, report testing, etc., don't wait for the problem when you get on the machine;
Be sure to let the manufacturer send samples to you, and receive the goods according to the quality of the samples;
Sign a contract with the manufacturer to deal with the follow-up problem of substandard quality;
Be sure to choose earloop with good elasticity.Because of the epidemic situation, masks are worn for a long time, and the elasticity of earloop is very important.The earloop choose materials with a ratio of spandex and nylon.After continuous research and development and testing, the ratio has reached the highest suitable elasticity.
