Reactive dye stuff forms oxygen bond with cellulose fibre, therefore color stays, it mean good fastness. 活性染色的染料能促使氧分子与面料纤维的结合,所以颜色能留在布料上,也就是说色牢度好。
Five types of bifunctional reactive dyes are selected and used to dye Tencel and viscose fibres, and their dyeing profiles are analyzed in detail. The dye-fibre bond stabilities on two fibres are also discussed. 本文选用了五种类型的双活性基染料对Tencel和粘胶纤维进行染色,分析了它们染色特征值的差异,并对它们与Tencel和粘胶纤维的成键稳定性进行了探讨。
To study the bond capability between round steel bars and reactive powder concrete, the bond stress and slippage are measured with steel bars of different diameters and anchorage lengths. 为了研究光圆钢筋与活性粉末混凝土的粘结性能,本文改变钢筋直径与锚固长度测定了粘结应力和滑移量。
Meanwhile wool dyeing with reactive dyes possess good washing fastness, light fastness, etc due to less polluting the environment and could generating covalent bond with wool. 而羊毛活性染料因对环境的污染较少,且活性染料能与羊毛反应生成共价键结合,而具有很好的水洗、耐光、耐汗渍牢度。
This dissertation involves mainly the following investigations and corresponding results: 1. A new bond-type anchor for CFRP tendons is developed, whose bond medium is Reactive Powder Concrete ( RPC). 主要的研究内容及其相应的研究成果如下:(1)开发了一种新的CFRP筋粘结式锚具,即采用活性粉末混凝土RPC(ReactivePowderConcrete)作为粘结介质的粘结式锚具。
To deeply understand the kinetic and gelation process, we applied reactive bond fluctuation lattice model to simulate hyperbranched A2+ B3 polycondensation. 为了深入认识A2+B3体系的动力学和凝胶过程,我们采用反应型键涨落模型模拟A2+B3缩聚反应。
