瓜尔豆胶印花糊料的性能研究

Property of printing thickener guar gum

比较了瓜尔豆胶和海藻酸钠印花糊料的粘度性能和印花效果。结果表明,瓜尔豆胶溶液粘度较低,更接近圆网印花对糊料粘度的要求,且耐酸碱性更强。瓜尔豆胶糊料印花织物的K/S值与海藻酸钠糊料的接近,且摩擦、皂洗、汗渍牢度较好,可以部分代替海藻酸钠作为印花糊料,并可降低生产成本。

The viscosity and printing effect of printing thickener between guar gum and sodium alginates were compared. The result showed that the viscosity of guar gum was lower and closed to the requirements of rotary screen-printing, and higher resistance to acid and alkali. The K/S value of the printed fabric with guar gum was closer to that with sodium alginate, and its color fastness of rubbing, soaping, and perspiration was better. So the guar gum can partly replace the sodium alginate as printing thickener and lower the production cost.
