    Abstract  The properties of polyimide flame retardant polyester blended fabric were studied.Six kinds of polyimide flame retardant polyester blended yarn with different blending ratios were designed and their plain weave fabrics were manufactured respectively.The flame resistance,air permeability,bendability,tear resistance and so on of six fabrics were tested.The test results showed that the weft flame resistances of six kinds of fabrics were all better than those of warp flame resistances.The air permeability of polyimide blended fabrics was obviously better than that of pure polyimide fabric.The fabric with 25% polyimide showed the lowest values on both flame resistance and tear resistance.The fabric rigidity was increased as the increase of polyimide percentage.It is considered that the property cost ratio of the blended fabric with 75% polyimide is the highest and the application value is the most.
