Monofilament nylon fishing nets need to be dried in the sun after adding adhesive, mainly because the adhesive needs to be dried and cured under certain temperature and humidity conditions. The ultraviolet radiation under the sun can accelerate the chemical reaction in the adhesive, making it dry and solidify faster. At the same time, the heat in sunlight also helps to increase the temperature of the fishing net, which can accelerate the penetration and adhesion of the adhesive on the fishing net, resulting in better consolidation effect. In addition, drying can also remove moisture from fishing nets, avoiding prolonged drying time or affecting the curing effect of the adhesive in humid environments.
