摘　　要：采用甘氨酸-氢氧化钠缓冲溶液控制染液pH值,实现分散染料对涤纶织物的碱性染色。结果表明,当染液pH值为8.5左右时,染料上染百分率和染色织物的K/S值最高。碱性染色织物的色泽、匀染性、摩擦牢度、皂洗牢度与酸性染色相当,织物K/S值高于传统酸性条件染色。Alkaline dyeing of polyester fiber was carried out using buffer solution of glycine and sodium hydroxide to control pH value of dyeing liquid. The result showed that the dye-uptake and the K/S value were highest when the pH value of dyeing liquid was about 8.5. The color, the uniformity, dry and wet rubbing fastness and washing fastness of alkaline dyed fabric were equal to those of acidic dyed fabric, and the K/S value of alkaline dyed fabric was higher than that of acidic dyed fabric.
