What material is a reflective raincoat

What material is the reflective raincoat? How to distinguish the quality of reflective raincoats? Reflective raincoat, literally, is a rainproof clothing that integrates rainproof and reflective protection. So how can it be both rainproof and reflective?
First of all, in terms of fabrics, there are two categories of fabrics for raincoats: high-covered fabrics and coated fabrics. The high cloth is usually woven from finer chemical fiber yarns, and the density is very high. In addition, the chemical fiber yarn itself is not water-absorbent, resulting in the high cloth being impermeable.
Our commonly used umbrellas and some basic raincoats are made of high cloth. Of course, this kind of impermeability is also limited to small and medium rainfall for a period of time. For example, if it is a long-term heavy rain environment, the umbrella will still leak.
At this point, we need to use another fabric coated fabric.
To be precise, a coated fabric is a fabric that has been specially processed, with two layers or even multiple layers. It is to use solvent or water to dissolve the required coating rubber particles, such as PU glue, AC glue, PVC, PE glue, etc. into a salivating shape, and then use a certain method to rotate the net, scraper or roller evenly on the cloth. Cotton, polyester, nylon and other substrates, and then fixed by the temperature in the oven to form a uniform layer of covering rubber on the surface of the fabric, and then achieve waterproof, windproof, breathable and other functions.
This principle is actually very simple, but the operation is the key! That is to say, the current fabric factory generally uses toluene or methyl ethyl ketone to dissolve the required coating rubber particles, such as PU glue, AC glue, PVC, PE glue, etc. into a salivating shape, which is related to the ratio of glue and sol. The viscosity, etc. are then uniformly coated on the fabric with a scraper method, such as cotton, polyester, nylon and other substrates, and then fixed by the temperature in the oven to form a uniform layer of covering rubber on the surface of the fabric, and then achieve waterproofing. , windproof, breathable and other functions!
Coated fabrics or fabrics generally have a higher improvement in cracking, and these coated fabrics are used in down jacket fabrics, ski wear fabrics, work maintenance clothing fabrics, field sportswear fabrics, etc.
And if the raincoat is expected to have both rainproof and protective functions in rainy days, we need to add another kind of reflective material to the original raincoat, usually reflective tape and lattice tape, or reflective paint.
