改性瓜尔豆胶印花性能探讨

对改性瓜尔豆胶和海藻酸钠印花糊料的各项性能及其用于棉织物活性染料印花效果进行对比.实验表明,改性瓜尔豆胶的成糊率较高,其PVI值比海藻酸钠印花糊料PVI值低,粘度较大,更接近平网印花对糊料粘度的要求,且印花织物具有较好耐摩擦、耐水洗性能;改性瓜尔豆胶糊料其印花织物的K/S值与海藻酸钠糊料的印花织物相接近.因此,使用改性瓜尔豆胶可以部分替代海藻酸钠作为印花糊料,以降低生产成本.

Research the printing properties of the modified guar gum

The effects of reactive dyes printing between modified guar gum and sodium alginates were compared on the cotton fabrics including a variety of their properties tested.Experiments indicate that modified guar gum has high rate of paste,the PVI value of modified guar gum is lower than sodium alginates＇s,cotton fabrics useing modified guar gum has better friction and wash property,and modified guar gum＇s viscosity are close to the plate scream printing of paste viscosity request;the cotton fabrics＇s K/S with modified guar gum are similar to the cotton fabrics＇s K/S with sodium alginates.Therefore,sodium alginates can be replaced by the modified guar gum as printing paste,so as to reduce the production cost.
