This invention relates to the insect protected textile making method, the character is that it uses dip-dyed or roll-dyed to dye the Pyrethrum Ester onto the synthetic fiber textile or yarn, wherein the synthetic fiber includes the composite silk, single silk, stable fiber textile and natural fiber blended or interlaced textile of the polyester, polyamide, polyurethane, polypropene, polyethene, polyacrylonitrile, polyvinyl chloride, the yarn is the related composite silk, single silk, stable fiber textile and natural fiber blended or interlaced yarn; the Pyrethrum Ester is hydrophobic, its molecular weight is less than 700, the decompose temperate is higher than that is dip-dyed or roll-dyed, and it has at least one group of the -OH,-CN, -NH2,-NHR,-NR2,-NHCOR,-I,-CI,-Br,-NO2,-SONH2. The advantage of this invention is that the production flow is short, the operation is simple; and the dosage is controlled.
