活性黑KN-B的日晒牢度与染色工艺关系的研究

本文对活性黑KN-B(C.I.Reactive　Black 5)染纯棉织物的染料浓度,固色率和染色后处理条件与日晒牢度的关系,以及三原色拼色时对日晒牢度的影响做了探讨,同时对涤/棉织物两浴法染色的活性黑KN-B与分散蓝HBGL对其日晒牢度的影响做了研究。结果表明:活性黑KN-B染纯棉织物,其日晒牢度随染料浓度和固色率的增加而提高,且固色率为70％以上时,日晒牢度大幅度提高。染色后处理,碱剂与皂煮对日晒牢度亦有一定的影响。使用活性黑KN-B,活性红M-3BE,活性黄M-3RE拼色对织物染色时,在KN-B的浓度为1％以下,其日晒牢度随浓度的增加而下降,在KN-B的浓度超过1％时其日晒牢度随浓度的增加而升高;日晒牢度随活性红M-3BE与活性黄M-3RE的浓度的增加而增大。采用分散/活性二浴法染涤/棉织物,其日晒牢度随KN-B浓度的增加,先降低后升高,在染料浓度大于1％时,日晒牢度几乎不在变化;但其日晒牢度随分散蓝HBGL的浓度的增加而增大。

Synthesis of methine dyes derived from indol‐2‐ones and their dyeability on polyester fibres

Three series of methine dyes were synthesised by the condensation of indol‐2‐ones with aryl acroleins. The structures of these dyes were confirmed by ¹H nuclear magnetic resonance spectroscopy, infrared spectrometry and elemental analysis. The ultraviolet‐visible absorption spectra of the dyes were examined in different solvents. The maximum absorption wavelength ranged from 386 to 495 nm. The dyes were applied to polyester fibres, and the colour gamut and dyeing properties were investigated. Results showed that the dye uptake (percentage exhaustion) was 86.9–92.0%, with the hue changing from yellow to red. The rubbing fastness, wash fastness, and sublimation fastness were between 4 and 5.

A series of new 4-aminoazobenzene dyes was synthesised. Absorption maxima and some important technical properties (lightfastness and fastness to washing) on nylon-6.6 and on wool were measured. A number of similar previously described structures were also prepared and characterised. Colour and constitution relationships in this series of dyes were established.A statistical analysis of their fastness properties by a modified Free-Wilson method was carried out. The validity of the additive model was confirmed and quantification of substituent contributions was obtained.     

Synthesis of temporarily solubilised azo disperse dyes containing a β‐sulphatoethylsulphonyl group and dispersant‐free dyeing of polyethylene terephthalate fabric

Disperse dyes containing a β‐sulphatoethylsulphonyl group have temporary solubility and can be applied for dispersant‐free dyeing of hydrophobic fibre. Six novel temporarily solubilised azo disperse dyes having a β‐sulphatoethylsulphonyl group in their structures were synthesised, and their dyeing properties on polyester were investigated. As a dye intermediate, a diazo component having dibromo groups was prepared, and 4‐diethylamino‐4′‐(2‐sulphatoethylsulphonyl‐4,6‐dibromo)azobenzene dyes were prepared by a diazo‐coupling reaction. Then, the dyes containing dicyano groups were prepared by cyanation of corresponding dyes with dibromo groups. The absorption maxima of the dyes were affected by the substituents in the diazo and coupling component rings and varied from 434 to 616 nm in dimethylformamide. Polyethylene terephthalate woven fabric could be dyed with the synthesised temporarily solubilised dyes without using any dispersants. Dyebath pH affected the K/S value at maximum absorption as well as percentage exhaustion on polyethylene terephthalate fabric, and the optimum pH was 5. The dyes gave brownish orange, red, purple, and greenish blue hues on polyethylene terephthalate fabrics, and colour build‐up was good. Wash fastness was good to excellent, rubbing fastness was moderate to excellent, and light fastness was poor to moderate.

Synthesis,spectral and dyeing properties of phenylazopyrazolone‐containing acylamide disperse dyes designed for poly(lactic acid)

A series of phenylazopyrazolone disperse dyes containing an acylamide moiety were synthesised from carboxyl‐containing acid dyes via chlorination and amidation with different sorts of amines. The structures of these new dyes were confirmed by Fourier Transform–infrared, proton nuclear magnetic resonance, mass spectroscopy and elemental analysis. Their solvatochromic properties in different solvents were also investigated and the absorbance spectra of the acylamide dyes in solution exhibited a red shift when dissolved in dimethylformamide, compared with acetone. Their dyeing behaviour, including dye sorption, colour build‐up and colour fastness properties on poly(lactic acid) fibres, was also determined, whereupon it was found that the tertiary acylamide dyes simultaneously exhibited high dye sorption and satisfactory colour build‐up and fastness properties on the poly(lactic acid) fabric.
