The 'outdoor jacket fabric' in the industry is a fabric with waterproof, moisture permeable and water permeation resistant performances, so that the outdoor jacket fabric is defined as the 'outdoor jacket fabric' for distinguishing from other fabrics; the coating and the lamination are produced according to two methods of the processing method; the medium-sized jacket and the ultralight jacket are classified according to the application range, the fabric of the medium-sized jacket is mostly 70D chinlon and 75D terylene fabric, and the medium-sized jacket is used for outdoor sports such as mountaineering and hiking and has wider application than the ultralight jacket.

On the other hand, the antistatic function of the fabric is mostly obtained by weaving metal wires or finishing the fabric by using an antistatic finishing agent. The clothes made of the metal wire fabric are easy to wear and lose efficacy in the processes of bending elbows and knees for many times; whereas antistatic finish products do not or only for a limited number of times have a wash fastness.

At present, most of the outdoor and domestic outdoor jacket fabrics are solvent type waterproof moisture permeable polyurethane coating adhesive coating products, the produced fabrics have better waterproof moisture permeable and water impermeability performances, but the production process is not environment-friendly, and the cloth surface after finishing has residual organic solvents such as toluene, DMF, butanone and the like, which are harmful to human health, so the outdoor jacket fabrics finished by the water-based waterproof moisture permeable polyurethane coating adhesive are widely researched by researchers, but no relevant documents report a mature processing method suitable for the medium-level outdoor jacket.

Chinese patent CN200910152399.4 entitled antistatic waterproof moisture permeable coated fabric, wherein the coating primer adhesive is prepared from hydrophilic polyester polyurethane, isocyanate bridging agent, acid bridging promoter, toluene and butanone; coating glue is applied on the surface of the coating layer by using hydrophilic polyether polyurethane, butanone, toluene, DMF (dimethyl formamide), conductive filler and white pigment as raw materials; the polyester fabric treated by the glue has no other performances except antistatic, moisture permeable and water pressure resistant performances, and meanwhile, the coating glue contains organic solvents of toluene and butanone.

In addition, the fabric of the outdoor jacket also needs to have good strength and stability, and can have good antistatic and arc-proof capabilities when used outdoors so as to improve the safety of a wearer. At present, the fabrics which can avoid the defects and solve the problems are rare.
