摘要
以邻、间、对硝基苯胺为重氮组分,1-(4-磺酸苯基)-3-甲基-5-吡唑酮为偶合组分,采用偶合、还原反应分别合成结构相近但氨基位置不同的3种水溶性芳伯胺染料D1、D2、D3,利用质谱、红外光谱、核磁氢谱及紫外-可见光谱等手段对染料结构进行验证。将染料D1、D2、D3分别通过常规酸性染料染色法、无醛低温染色法和Mannich反应染色法上染蚕丝织物,分别测定染色蚕丝织物剥色前后的K/S曲线,对比染色蚕丝织物的色深及各项色牢度。结果表明:采用Mannich反应染色法,D1无法上染蚕丝织物,D2、D3能够上染蚕丝织物;与常规酸性染料染色法相比,D2、D3采用Mannich反应染色法获得的色深更高,耐水洗和耐摩擦牢度更好。
In this paper,the o,m,p-nitroaniline as diazo component,and 1-（4-sulfoacid phenyl）-3-pyrazolone was selected as the coupling component,and adopted coupling and reduction reaction to synthetize 3water-soluble aromatic primary amine dyes D1,D2 and D3with similar structure and different amino positions.The structure of the dyes was verified by mass spectrometry,FTIR,1HNMR and UVvisible spectrum.Silk fabrics were dyed by D1,D2 and D3through conventional acid dyes,aldehyde-free low-temperature dyeing and Mannich reaction dyeing method.Besides,the K/Scurve of the colored silk fabric before and after soaping was measured.The color depth and color fastness for the silk fabric were compared.The results show that if Mannich reaction is adopted,D1 can not dye silk fabric,while D2 and D3can dye silk fabric.Compared with the conventional acid dye dyeing method,color depth,washing and rubbing fastness of silk fabrics dyed by D2 and D3gained by Mannich reaction are better.
