摘　　要：针对海藻酸钠活性印花用糊料不耐储存且尿素用量大等问题,提出以乙二胺作为偶联剂,对海藻酸进行改性,制得改性海藻酸糊料。结果表明:与海藻酸钠糊料相比,改性海藻酸糊料具有黏度高、抱水性好、耐储存性良好,印花效果渗透性好、色牢度高、轮廓清晰,并且减少了尿素的使用。A novel modified alginate thickener is developed with ethylenediamine as the coupling agent in order to solve the problems of poor storage stability and large consumption of urea.The results show that compared with sodium alginate thickener,modified alginate thickener can reduce the amount of urea,and the thickener has higher viscosity,good water conservative property,good storage stability,good printing effects,such as high permeability,color fastness and printing clearness.
