摘　　要：应用阳离子改性剂PECH-amine对棉织物改性,应用不同用量的活性红B-2BF上染改性后和未改性的棉织物,比较了K/S值和上染率.试验结果为K/S值提高149.17%;上染率在染料用量为1%￣3%(owf)时增加42.84%￣61.25%,证明改性后的棉织物活性红B-2BF上染率与K/S值显著提高.PECH-amine, a cationic modifier, was used to modify the cotton fabrics. The modified and unmodified cotton fabrics were dyed with different concns. of reactive red B-2BF, and the K/S values and dye uptake were compared. The experiments resulted in K/S value increase by 149.17%, and dye uptake increase by 42.84%~61.25% when the dye was used at 1%~3%(owf). It was shown that the dye uptake and K/S values were markedly improved when the modified cotton fabrics were dyed with the reactive red B-2BF.
