This study aims to develop a self-dispersive and reactive carbon black (DRCB) to improve its application in cotton fabric. CB was functionalized with γ-aminopropyl triethoxysilane (KH550) and then grafted with as-synthesized compound to obtain aqueous phase DRCB. FTIR analysis confirmed the successful grafting of as-synthesized compound onto KH550-modified CB surface. The weight grafting of DRCB on DRCB-15 % dyed cotton fabric was approximately 15.18 %, with a half weight grafting time of around 17 min. TEM observation demonstrated that DRCB had a core-shell structure with the mean sizes of 36.02 ± 4.30 nm. Particle size analysis revealed that DRCB had smaller average aggregate size of 110.3 nm and higher zeta potential of -33.7 mV than CB, indicating that DRCB had much better dispersion in aqueous media than CB. Cotton fabric was effectively dyed with DRCB, providing excellent color depth of 60 (K/S value) with dry rubbing and wet rubbing/washing color fastness of Grade 4 and Grade 3, respectively. DRCB dyed cotton fabric exhibited outstanding anti-UV and anti-static properties, with no significant difference in softness and tensile property before and after dyeing. This research proposed a new method to solve nanoparticle agglomeration and prepare textile dyes with excellent self-dispersivity and reactivity.
本研究旨在开发一种自分散性反应性炭黑（DRCB），以改善其在棉织物中的应用。用γ-氨丙基三乙氧基硅烷（KH550）对炭黑（CB）进行功能化处理，然后与合成的化合物接枝，得到水相DRCB。傅里叶变换红外光谱（FTIR）分析证实合成的化合物成功接枝到KH550改性的CB表面。DRCB在15% DRCB染色棉织物上的重量接枝率约为15.18%，半重量接枝时间约为17分钟。透射电子显微镜（TEM）观察表明，DRCB具有核壳结构，平均尺寸为36.02±4.30纳米。粒度分析显示，DRCB的平均聚集体尺寸较小，为110.3纳米，zeta电位比CB高，为-33.7毫伏，表明DRCB在水介质中的分散性比CB好得多。用DRCB对棉织物进行有效染色，提供了出色的色深60（K/S值），干摩擦色牢度和湿摩擦/水洗色牢度分别为4级和3级。DRCB染色的棉织物表现出出色的抗紫外线和抗静电性能，染色前后的柔软度和拉伸性能无显著差异。本研究提出了一种解决纳米颗粒团聚问题的新方法，并制备了具有优异自分散性和反应性的纺织染料。
