This invention discloses a surface wetting process for bronze mesh. The invention designs a fiber-reinforced rigid composite mesh, which combines fibers with copper mesh, using the copper mesh as the skeleton base. The excellent mechanical strength and rigidity of the bronze mesh itself provide strong physical support for the modified fiber layer. The molded composite material retains the chemical activity of the fibers while also having properties such as compressive strength and tear resistance, which better meets the installation and operation requirements of industrial continuous separation equipment.

The utility model discloses a down jacket heat insulation fabric, and belongs to the technical field of garment fabrics. A down jacket heat insulation fabric comprises an outer layer, and a heat insulation layer, a down middle layer and a skin-friendly inner layer are sequentially arranged on the inner side of the outer layer. The outer layer, the heat insulation layer and the skin-friendly inner layer are sewn and fixed through sewing threads, the down feather middle layer is located between the heat insulation layer and the skin-friendly inner layer and filled with animal fibers, plant fibers and chemical fibers, the heat insulation layer is soaked in a zirconium oxide solution and naturally dried, and the zirconium oxide fibers can provide excellent heat insulation and corrosion resistance for the down jacket when serving as outer layer fabric. Through the multi-layer structural design, particularly the combination of the heat insulation layer and the down feather middle layer, the down feather down feather down feather fabric effectively isolates outside cold air, locks body temperature and provides an excellent warm keeping effect. The heat insulation layer is treated by a special weaving process and a zirconium oxide solution, so that the heat insulation performance is further enhanced.
