摘要
为改善纳米炭黑的凝胶化和与纤维粘附牢度差的问题,采用热溶固着直接印花工艺进行纳米炭黑涤纶印花,探讨了两种合成增稠剂(PTF-3、PTF-S)的复配对炭黑流变性的影响,以及3种黏合剂(FC-65、DT、HF-98)对印花性能的影响。研究结果表明:纳米炭黑会引起合成增稠剂流体流动模型的转变,具有黏塑流型流体的特征,PTF-3和PTF-S的复配能提高PVI值,明显降低纳米炭黑的凝胶化。优化的印花色浆组成为:纳米炭黑分散液8%,PTF-3 1.4%,PTF-S 0.6%,黏合剂HF-98 4%。制备的涤纶织物具有较好的色深度,干/湿摩擦牢度和皂洗牢度都高于3~4级,且有较好的抗静电性和抗紫外线性能。
In order to improve the gelation and adhesion fastness of nano-carbon black on fibers, the thermosol fixation directly printing with nano-carbon black on polyester is carried out. The effects of two syn- thetic thickeners （PTF-3, PTF-S） on rheological properties of nano-carbon balck are discussed. The ef- fects of three kinds of adhesive agents （FC-65, DT, HF-98） on printing performance are also discussed. The result shows that nano-carbon black can lead to the transformation of fluid flow model of synthetic thickener, which has the characteristic of viso-plastic. The PTF-3 and PTF-S can increase the PV/value and decrease the gelation of nano-carbon black obviously. The optimal printing paste is nano-carbon black disperision 8%, PTF-3 1.4%, PTF-S 0.6% and adhesive HF-98 4%. The treated polyester fabric has better color depth, the fastnesses to dry/wet rubbing and soaping of Grade 3-4, as well as better anti- static properties and anti-UV properties.
