We are choosing to buy reflective vests. Generally, it is recommended to choose brighter colors for fabrics, such as (fluorescent yellow, orange, etc.). Just like the high-speed traffic police we see now, reflective vests and raincoats worn by road administrations are better. , Because not only the clothes themselves are bright in color, the warning effect is good, but the reflective strips are also very powerful.
The following is a summary of the purchase points of reflective vests (other reflective clothing, such as reflective raincoats, are only partially applicable, due to the big difference in fabrics, they pay attention to waterproofing and attach importance to sealant, which will be discussed later):
1. The fabric should not be too thin. The mesh cloth should be more than 100 grams, and the plain cloth (called warp knitted fabric in the industry) should be at least 110 grams. This refers to the square gram weight, the weight is too low, one is not abrasion-resistant, and the second is fluorescence. difference.
If it looks very transparent, it is only 60g to 80g.
2. The reflective strips should be protected by 360 degrees, that is, at least one reflective strip is a full circle around the torso. In case of disconnection, it should not exceed 5cm. If it is not good, don't disconnect it.
3. Easy to put on and take off. The placket is usually made of buckles, followed by zippers. For example, Canada, the wicked Canada, is the bird country that caught Meng Wanzhou. Their shoulders and waists are connected by buckles, which is easy to take off and escape. It can be used at times. For example, if you get caught by something, just break free.
4. The quality of the reflective strips should be at least high-bright, both Type 1 and Type 2 are acceptable. If both domestic and international standards are required, they must be at least Type 2, also called Level 2, and the industry is the reflectance, or retroreflective coefficient. 330 or more.
5. If the reflective strip is not made of fabric, it is made of PVC, which looks like plastic. For winter use, it must be cold-resistant, otherwise it is easy to break. The technology of this kind of reflective strip is generally imported and relatively mature, unlike fabric The (nylon bottom, TC bottom, cotton) made in China is very mature.
(1) The core material of the fabric does not have a brand. Generally, you can only choose according to the first item. In further depth, you need to check certification and testing. It depends on the fabric factory and dyeing factory. This is complicated.
(2) Reflective strips of core materials. Domestic reflective strips generally include ordinary, high-bright, and bright silver (normally recommended to use high-bright or bright silver). Foreign brands include 3M and Ruifei.
