The data in the table show that the down jacket fabric prepared in the embodiments 1-3 of the invention has excellent heat preservation and air permeability, and the fabric prepared by weaving 70% of terylene and 30% of polyarylate fiber into the base fabric layer has good elasticity, high tensile breaking strength and good air permeability; specifically, the thermal insulation layer is prepared from polyurethane, silica aerogel, porous graphene particles and a modified pore-forming agent, and as can be seen from the experimental results of examples 1 to 3, the polyurethane has good bonding strength, toughness and wear resistance, after the polyurethane is dyed and combined with the base fabric layer, an organosilicon chain segment with low surface energy can be enriched on the surface of the fabric, the polyurethane chain segment is close to the fabric and is tightly bonded with the fabric through hydrogen bonds and chemical bonds, the purposes of good water repellency and good fabric bonding property are achieved, the thermal insulation performance of the fabric can be greatly improved, countless nano-scale pores exist in the silica aerogel through the combination of the silica aerogel and the porous graphene particles, the thermal insulation and air permeability can be improved, the graphene has a far infrared effect, and the thermal insulation effect of the silica aerogel can be improved in an auxiliary manner, in addition, the porous graphene particles are adopted, so that the fabric has high heat preservation performance and air permeability; the experimental results of the embodiment 1 and the comparative example 1 show that the thermal insulation performance and the air permeability of the down jacket fabric without adding the silica aerogel are greatly reduced, because countless nanometer-scale air holes exist in the silica aerogel, the extremely high thermal insulation performance and the air permeability can be improved; it can be seen from the experimental data of example 2 and comparative example 2 that the thermal property of the fabric prepared in examples 1 to 3 is not much different from that of the conventional pore-forming agent but the air permeability is greatly reduced by replacing the modified pore-forming agent in the raw material for preparing the thermal layer with the conventional pore-forming agent, because the modified pore-forming agent can make the pore-forming substance in the polyurethane, and in the process of forming the micropores in the polyurethane, the modified pore-forming agent is added to improve the micropore structure of the polyurethane, so that the air permeability of the polyurethane is improved, while the conventional pore-forming agent also has the function of forming the pores in the polyurethane, but: the modifier oxazoline is added to effectively coat the pore-foaming agent in a multi-molecule accumulation mode, and the oxazoline is hydrophilic, and has enhanced moisture permeability and air permeability; the mechanical property of the polyurethane is reduced due to the increase of the air permeability, so that the touch feeling of the warm-keeping layer is improved; finally, it can be obtained from the experimental data of example 3 and comparative example 3 that the thermal insulation performance and the air permeability of the thermal insulation layer without the modified pore-forming agent are the lowest, so that the above conclusion can be demonstrated.
