The adsorptive effect of chitosan on acidic dye follows a sigmoidal trend. The chitosan-woven fabric after 98% de-acetylation achieved 98% and 95% dye adsorption in reactive dyes; and achieved 93% and 92% dye adsorption in reactive dyes in eight days. The higher the degree of de-acetylation, the better the dye adsorption.

Sulfonic-4-(β-sulphatoethyl-sulphone) phenylamine is often applied to producing bifunctional-soluble reactive dyes and is an important dye intermediate. It plays an important role in the synthesis of KN style reactive dye M style double reactive dye and modified dissimilar double reactive dye. Used 2-sulfonic-4-(β-sulphatoethyl-sulphone) phenylamine as raw material can improve the uniformly dying performance and scourablility of dyestuff molecules and can improve the firm degree of colour staining.

2-磺酸-4-苯胺是制备水溶性双活性染料的重要中间体，在KN型活性染料、M型双活性染料以及改性异种双活性染料的合成中起着重要的作用，用2-磺酸-4-苯胺作原料合成活性染料可增加染料分子的匀染性和易洗涤性，提高染料的粘色牢度。

Through taken the measurements of pH, TOC, UV-Vis spectra and high-performance liquid chromatograph in the degrading process of solution ,it was found that the COD of dye solution increased, pH continuing declined and TOC reduced gradually. The UV-Vis spectra and high-performance shown that though dye molecules had been destroyed, Strong Chromophore Azo Double Bond of dye was certainly under attack, the big conjugated system was vandalized and dye molecules were decolorized degradation, but they were not completely changed into carbon dioxide and other inorganic matter by mineralization, it appeared accumulation of aromatic ring and double benzene nucleus, so it is thus evident that complete destruction of aromatic ring is more difficult than the double benzene.

通过测定直接大红染料脱色过程中的溶液pH、TOC、紫外可见光谱图和高效液相色谱图可知，在脱色处理时间(6h)范围内，染料溶液的COD值增大， pH值持续下降，TOC值逐渐降低，结合紫外可见光谱图和高效液相色谱图，说明染料分子虽然已经遭到破坏，染料分子内强生色基团偶氮双键确实遭到攻击，大的共轭体系被破坏，染料分子被脱色，却没有完全被彻底矿化成二氧化碳等无机物，出现了芳环和萘环结构的累积现象，可见完全破坏芳环比破坏偶氮双键发色团更困难。

From the investigation into the visible spectra and performances on textile of these azo dyes, as acid dye, it was found that these dyes had deep coloring effects on dyeing wool or silk, and five of which could dye wool into black one at 3% o. w. f., especially the diazo dye derived from 2, 8-diamino-10-methoxy-5, 10-dihydrophenophosphazine 10-oxide and acet-J-acid, it could not only dye wool into black one but each fastness of the obtained dyed sample was good.

对这些已知结构的染料进行浸染染色，结果发现，它们作为酸性染料，在羊毛及丝绸纤维上染色时，能够获得比一般偶氮染料不宜获得的深色效应，其中5支染料得到黑色染样，尤其由2，8-二氨基-10-甲氧基-5，10-二氢磷杂吖嗪与乙酰J-酸形成的双偶氮染料得到黑色染样，其各项牢度都比较理想。

Whether vat dye, disperse dye or reactive dye, the color fastness mainly depended on dye structure and dyeing process.

染料的染色牢度，主要取决於染料的结构特征和染色工艺的准确性。

The result shows, compared with conventional high-temperature leveling agent, the leveling agent JL can reduce the dyeing rate of the higher rate dye, increase the dyeing rate of the lower rate dye, improve the dye compatibility, migration property, and high temperature dispensability.

结果表明，与常规高温匀染剂相比，高温匀染剂JL能使初始上染速率较高的染料上染速率降低，使初始上染速率较低的染料上染速率提高，改善了染料的配伍性，提高了染料的移染性和高温分散性，且对染品的染色牢度影响不大。

In the process of electro-membrane filtration, the applied operation condition and membrane do not have significant electroosmosis effect through related experiment. Under the operation of 98KPa pressure, only 6% flux was increased, which showed the increase of flux in the applied electric field process mainly from electrophoresis effect. The effect of dye filtration by membrane is mostly influenced by the basic nature of dye, including size of molecular weight, electrophoresis motility and the adsorbability of dye to membrane.

在外加电场薄膜程序中，所用的操作条件以及所使用的薄膜，经电渗透实验显示电渗透的效应不明显，而在98KPa压力操作下，也仅增加6%的通量贡献，显示外加电场程序通量之提升主要来自电泳作用；薄膜过滤染料的效果主要受到染料基本性质的影响，包括分子量大小、电泳动能力与染料对薄膜的吸附能力。
