There are many manufacturers and purchase channels for reflective vests. After purchasing, people found that they were not good enough to wear them at night, which was far from meeting their expectations. Another one is very good when I bought it and just put it on. I feel the reflective effect is very good when I do night activities. After several times of washing, it doesn't work. Why?
This is easy to understand. The reflective strips of reflective vests can be divided into three types in terms of brightness: bright, bright and silver. The price can be reflected through the increasing process. The better the reflective effect is, the brighter the price will be, which can solve the * * problem. Some reflective vests are not bright when they are bought, which are all problems of reflective strips.
The second problem is that the light is very bright at the beginning. After several times of cleaning, it doesn't light up. This shows that the glass crystal bonding process is incorrect, the work is jerry built, and the bonding surface is not treated. As a result, the glass crystal falls off during the cleaning process. The more you clean, the worse it is.
Conclusion: These are the small actions of some bad businessmen. They should be careful when buying, whether they have production capacity and mature technology, and whether they are the real manufacturers is the most important. Be sure to polish your eyes before buying.
