直接黑

As a result, make sure the proportion of black dye is 4.2%, and the formula of the dyestuff C.I. Direct Black 19: C.I. Direct Black 168: Dyestuff I=3:1:1, and when using two surfactants, printing liquidity is better, at same time compare to printing result with national inks, and the result is that confecting inks excels national inks in soaking paper, curliness and edge definition.

最后确定黑色染料所占比例为4.2%，各染料配比为直接黑19：直接黑168：染料I=3：1：1，并且当用两种表面活性剂进行复配时，打印流畅性较佳；同时与国产品牌墨水作打印测试对比，结果自制墨水在有无洇纸和卷曲以及边缘清晰度方面优于国产品牌墨水。

It shows that the rate of dye - uptake was good and the fastness to soap and solarization were comparable with black direct dyestuff L - 3BG.

结果表明，染料的上染率较高，染料的耐皂洗牢度和耐日晒牢度与直接黑L-3BG相当。

The fixing and darkening effects on Direct Black GF treated by aqueous silica sol were also discussed in this paper.

本论文对硅的水溶胶用于直接黑GF的固色和增深处理进行了探讨。

Experimental data showed that the aqueous silica sol had excellent fixing and darkening effects on Direct Black GF on cotton.

实验结果显示，硅的水溶胶对直接黑GF有着明显的固色作用和增深作用。

In this paper, silica sol in ethanol was prepared and used for fixing Direct Black G dyed cotton, and good washing fastness was obtained.

本论文制备含硅醇溶胶并对直接黑G进行固色处理，取得了较高的固色效果。

The color fastnesses of treated fabrics dyed with Direct Black GF could compare beauty with sulfur black or reactive black. The reflectivity curve fell greatly compared with untreated, and the darkening effect made it possible to get very full black colour with excellent wet fastness with relative small amount of the dye .

经溶胶-凝胶整理后，直接黑GF的各项色牢度能与硫化黑、反应性黑相媲美，反射率曲线较处理前有较大幅度的降低，增深效果使得用较少的染料染得较浓的黑色成为可能。

经溶胶-凝溶胶一凝胶技术在纺织上的应用与研究摘要胶整理后，直接黑GF的各项色牢度能与硫化黑、反应性黑相媲美，反射率曲线较处理前有较大幅度的降低，增深效果使得用较少的染料染得较浓的黑色成为可育旨。

The dyes were extracted from textiles composed of natural or chemical fibers by methanol under ultrasounication, and then eluted with gradient by acetonitrile and 5 mmol/L ammonium acetate from an RP-C18 column with two segments in effluents. The first effluents accommodated Acid Red 26, Direct Blue 6, Direct Black 38 and Direct Red 28 with negative ionization mode, while the second accommodated Basic Red 9, Basic Violet 14, Disperse Blue 1, Disperse Orange 11 and Disperse Yellow 3 with positive ionization mode. Thus the investigated compounds could be identified simultaneously with single-run analysis no matter which type of the fibre the sample was and no matter which category of the dye the analyte was.

用甲醇超声同时提取天然纤维和化学纤维上的染料，以5 mmol/L乙酸铵和乙腈为流动相在C18柱上于前段洗脱酸性红26、直接蓝6、直接黑38和直接红28（采用电喷雾质谱负离子模式检测），于后段洗脱碱性红9、碱性紫14、分散蓝1、分散橙11和分散黄3（采用电喷雾质谱正离子模式检测），实现了对不同种类纤维织品中分属4类性质不同染料的一次提取和一次分析检测。

An aqueous solution containing50 mg/L of dye could be decoloured over a Agloaded TiO2 catalyst with a 40- 60 min irradiation, which was 15-40 min less than that in thecase of using a pure TiO2 as a catalyst.

直接耐晒翠蓝（50mg／L）和直接黑（50mg／L）染料溶液脱至无色的时间分别为35min、60min及60min，而采用载银TiO2催化剂，上述染料溶液脱至无色的时间分别为20min、30min及20min。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
