First, the size of the reflective vest
There are many styles of codes, is to say whether the body height and weight, only one size can be selected (usually L), whether or not. The reflective vests are concerned only with protective properties, without focusing on the beauty and comfort of the dress.
Another is, like ordinary fashion, the production of M, L, XL, 2XL, 3XL and other sizes. Buyers can choose the right size according to their own shape, taking into account the safety protection and comfort and beauty.
Secondly, the area of reflector and reflective distance
In accordance with the requirements of the national standard GB20653 (occupation service national standard for high visibility warning), reflective band width occupation reflective clothing should not be less than 5cm, to ensure that the most appropriate reflection effect. And we can often see in the road below this kind of environmental sanitation coverall, the width of reflector is not even 3cm.
As far as reflector distance is concerned, GB20653 specifies 330m, because the driver finds the wearer outside the 330m and takes the brake or avoidance measures in a timely manner, so that it is relatively safe. And we see a lot of reflective clothing, especially washed over reflective clothing, reflective distance and even not 50m, I would like to ask about security protection?
Finally, the number of washing times from one to dozens of times. The worst quality, that is, disposable, once washed, the reflective material fell off, almost no longer reflective effect. Under normal circumstances, the number of washing in 10-20 times, the quality is no problem, so a quarter change once you can guarantee the basic reflection effect. Well, it usually comes up to 30-50 times, like 3M's reflective material, which is better in quality. It needs to be emphasized that the washing method for washing reflective clothes will also affect the number of washing and the service life.
