5 pieces of a reflective vest and 50 pieces of a reflective vest, looks similar, in the end what is the difference?
First of all, to introduce, reflective clothing usually refers to the night can play a reflective warning effect of the clothes. Clothing by the reflective material (reflective tape or lattice band) and the base fabric of two parts, when the night when the light shines, the reflective material will be part of the light reflected back to alert the people who see the reflected light itself does not glow .
Second, in accordance with national and industry standards, the manufacturer of reflective clothing must be controlled with the reflective clothing from the design, material selection, sewing and post-processing and other aspects of strict control, rather than directly in the ordinary clothing stitched one or Several reflective tape so simple.
Open the shopping site, search reflective garments, the results have more than a hundred pages, as many as ten thousand, then how do we find the high quality from the vast sea of clothes
In fact, the reflective distance from the reflective tape, washing times, reflective tape width and other reference terms, the national standards are clearly defined.
Someone asked, do not meet the standard reflective clothing can not wear it? I think people have some ten eight reflective clothing is not very reflective? Yes, not to say that non-standard reflective clothing can not wear, but not in accordance with the standards of design and production of reflective clothing, more or less there will be some problems and security risks.
For example, the national standard GB20653 reflective distance is 330m, you wear a reflective clothing only 100m away, of course, is also possible, but in an emergency, you give others less reaction time, your Danger also increased a lot, when it comes to life, a second is also very important.
There are reflective tape above the "phosphor", is actually a kind of thing called glass beads, night reflections rely on their refraction and refraction of light.
Some reflective clothing, to achieve the reflective distance is 330m, but due to processing is not in place, the glass beads off easily. This led to some reflective garments washed several times after not reflective.
Therefore, when we buy reflective clothing, to ask the store, the reflective clothing reflective distance is how much to support the number of washing, of course, the greater the reflective distance, the better the support of the number of washing the better.
On the pros and cons of reflective clothing quality, said in front of the reflective distance and wash the number of two visits, then it is not to say that these two criteria can buy high-quality reflective clothing?
Of course, the answer is no, judging the standards of reflective clothing there are many items, here again enumerated: reflective strip or lattice width.
National standard, reflective clothing reflective material width greater than or equal to 5cm. See this figure, I believe many people will find there are many non-standard reflective vest around. Because less than this width, reflective material is difficult or impossible to meet the requirements of the national standard 330m reflective distance.
