新型羧甲基纤维素钠/海藻酸钠复合印花糊料的印花性能

Printing Properties of New Carboxymethyl Cellulose/Sodium Alginate Composite Printing Paste

针对单一海藻酸钠糊料难以满足现代活性印花工艺要求,在已有研究基础上,选择以不同取代度的羧甲基纤维素钠(CMC)与海藻酸钠(SA)按照一定比例进行多元混合制备新型活性印花糊料,并比较其黏度、色浆PVI值及印花织物的K/S值、手感等综合性能。结果表明:混合高取代度羧甲基纤维素钠的新型活性印花复合糊料,其成糊率高,表面得色量及印花手感均满足较高印花要求,可替代纯海藻酸钠糊料,同时显著降低印花糊料成本。

In view of the fact that the single alginate paste can not satisfy many requirements of modern reactive printing technology,a new type of reactive printing paste was prepared by the multi-component mixing of carboxymethyl cellulose acid(CMC)and sodium alginate(SA)with different degrees of substitution.The viscosity,PVI value of color paste,K/S value and handle of printing fabric were measured and compared.The results showed that the new reactive printing composite pastes with high degree of substitution of carboxymethyl cellulose could be used as a substitute for pure sodium alginate pastes,and the cost of printing pasteat was significantly reduced.
