The composite fabric for deep cold protective gloves is prepared with polyimide fiber and aramid fiber,the physical and chemical properties and thermal protection properties of aramide 1313 mixed with polyimide fiber are analyzed,and the wet and heat resistance of stripping strength and composite fabrics of polyimide film covered with different thickness are tested.The results show that when the raw material ratio of the outer fabric is polyimide/aramid 1313/conductive fiber 50/48/2,film thickness is 0.03 mm,and wool thickness is 20 mm,the composite glove fabric still has good flame retardant,waterproof,thermal protection and thermal humidity comfort performance under ultra-low temperature,which can meet the requirements of firefighters in low temperature and deep cold environment.
