What kind of coating is good for reflective raincoats?

Reflective raincoat refers to a raincoat that sews a certain area of ​​reflective tapes or lattice tapes and other reflective materials on a traditional raincoat, so that it can take into account both rainproof and warning functions on rainy days (especially rainy nights). First of all, in terms of fabrics, there are two categories of fabrics for raincoats: high-density fabrics and coated fabrics. High-density fabrics are usually woven from finer chemical fiber yarns, with very high density. In addition, the chemical fiber yarns themselves are not water-absorbent, resulting in high-density fabrics that are impermeable to water.
Our commonly used umbrellas and some basic raincoats are made of high-density fabrics. 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, the coated fabric is a kind of fabric treated by a special process, with two layers or even multiple layers. It is to use solvent or water to dissolve the required coating rubber particles (including PU glue, A/C glue, PVC, PE glue) into salivation, and then in a certain way (rotary mesh, scraper or roller) uniformly It is coated on the fabric (with cotton, polyester, nylon and other substrates), and then fixed by the temperature in the oven to form a uniform covering rubber on the surface of the fabric, so as to achieve waterproof, windproof, breathable and other functions.
This principle is actually very simple, but the operation is the key! It is to use a solvent (the current fabric factory generally uses toluene or methyl ethyl ketone) to dissolve the required coating rubber particles (including PU glue, A/C glue, PVC, PE glue) into salivation (related to the rubber and The ratio of sol, viscosity, etc.) is evenly coated on the fabric (with cotton, polyester, nylon and other substrates) by a scraper, and then fixed by the temperature in the oven to form a uniform layer on the surface of the fabric. The cover rubber material, so as to achieve waterproof, windproof, breathable and other functions!
Coated fabrics or fabrics generally have a higher improvement in cracking. These coated fabrics are used in down jacket fabrics, ski wear fabrics, work protective clothing fabrics, outdoor sportswear fabrics, etc.
And if we want the raincoat to have both rainproof and protective functions in rainy days, we need to add another thing to the original raincoat: reflective material, usually reflective tape and lattice tape, or reflective paint.
