选用4只分散染料对聚酯超细纤维进行染色,并对其移染性、皂洗牢度及染料的高温分散性进行了研究。结果表明:染料的移染性与染料分子结构有关,分子量小,移染性好;皂洗牢度与染浴浓度有关,在相同条件下,染色浓度为4%时比12%高1级。碱性染色结果表明:BlueUP—GF在碱性条件下酯基水解严重,不适合碱性染色。 相似文献

根据Shell公司和Dystar公司的研究,用Optidye系统从分散染料吸附与上染率、染色温度、pH值、匀染性及染色牢度等方面解析了聚对苯二甲酸丙二酯(PTT)纤维的染色性能。PTT纤维在100℃就可染到深色,在60～80℃和90～100℃有两个吸附速度较快区域;PTT纤维属易染型纤维,在最高温度染保持30～40min即可。高温型分散染料在120℃染色,常压100℃染色无需pH值调节。分散染料染色牢度(洗涤、摩擦及耐光)非常好。 相似文献

以有机碱三乙醇胺为催化剂,邻苯二甲酸酐(简称苯酐)与自制阳离子改性剂WLS反应,制备苯酯助剂,并将其作为涤纶分散黑ECT染料常压染色的促染剂。通过系统研究,优化出苯酯合成工艺,并探讨苯酯助剂与N-正丁基邻苯二甲酰亚胺(简称亚胺)复配对分散黑ECT常压染色性能的影响。结果表明:苯酯与亚胺有很好的协同效应,二者质量比按2∶1复配时,可获得最佳染色效果。该复配促染剂应用于涤纶常压染色中,染色后织物先进行195℃焙烘2.5 min,再还原清洗,织物的染色深度K/S值和上染百分率较常压无助剂、同条件染色工艺显著提高,而且基本达到传统高温高压的染色效果。 相似文献

A series of monoazo disperse dyes derived from naphthalimide containing butyric acid has been applied on polyamide fabrics. The build up and dyeing properties of these dyes such as leveling property, wash, light, perspiration for alkaline and acidic conditions, and rubbing fastnesses on polyamide fabrics have been investigated. The results showed that the applied dyes are capable of producing red to bluish red hues on polyamide fabrics. Because of the presence of both carboxylic acid and hydroxyl groups on the molecular structure of Dye 3, it showed desired and more strength in respect to other used dyes. Comparing the build up of these dyes to commercial dyes such as disperse red 60 and disperse red 73 revealed that most of the used dyes have higher build up in comparison to the commercial ones. Measurement of fastness properties of dyed samples indicated that they have good wash (4–5), rubbing (4), perspiration (4–5), and heat fastnesses (4–5) and they possess less than moderate light fastness (3–4) on polyamide fabrics. © 2011 Wiley Periodicals, Inc.

The heterocyclic amines 2‐amino‐6‐methoxy‐ and 2‐amino‐6‐nitrobenzothiazole, 3‐amino‐5‐nitro‐[2,1]‐benzisothiazole, and 2‐amino‐3,5‐dinitrothiophene were diazotized and coupled to substituted N‐β‐acetoxyethylanilines to give dyes which colored cellulose acetate in red to deep blue hues. The color of the dyes is discussed with respect to the nature of the heterocyclic ring and to the substituents in the diazo and coupling component. Dyeing and fastness properties of the dyes on cellulose acetate are also reported. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 92: 3479–3483, 2004 相似文献

本文研究了染色助剂对涤纶超细纤维染色热力学的影响,研究发现:1、染色助剂的存在并未改变分散染料在涤纶纤维中的分配机理,即服从Nest定律;2、阴离子表面活性剂存在时,分散染料对涤纶超细纤维的亲合力降低,其中在110℃时降低的幅度比较大;染色热比不加阴离子表面活性剂时低得多,染色熵的绝对值也低得多;3、非离子表面活性剂在降低了分散染料对涤纶超细纤维的亲合力的同时,也降低了分散染料在染色过程中的染色热和染色熵的绝对值;4、载体的存在使得染色等温吸附曲线的斜率和亲和力均比较高,但是染色饱和值却较低;5、匀染剂SL的存在使得染色热和染色墒的绝对值均较高。 相似文献

In this study chitosan samples of different nature, prepared by hydrolysis with HCL and modification by reaction with dimethylaminobenzaldehyde in methanol were applied to acrylic and polyester fabrics by pad‐dry‐cure method in presence and absence of binder (acrylate based copolymer). The pretreated samples were printed with acid dye. The effect of acid hydrolysis, modification, and concentration of chitosan on the color strength of the prints was investigated. The printed fabrics were evaluated for color yield and fastness properties. The color strength of the prints in presence of binder was three times higher than in its absence. The enhancment in color strength was relies mainly on N% of chitosan. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008 相似文献

A series of water-soluble colored polyesters (polymeric dyes) were synthesized by interfacial polycondensation reaction of terephthaloyl chloride and various bisazodiols (monomeric dyes) that were derived from diarylidene cyclopentanone and diarylidene cyclohexanone by coupling with various diazonium salts of anthraquinone dyes containing the sodium salts of the sulfonic acid group. All the colored polyesters were characterized by their elemental analysis, IR and UV-visible spectroscopy, viscometry, solubility, and TGA. Color and dyeability of the polymeric dyes are discussed by comparing them with those of the corresponding monomeric dyes. The color fastness of the polymeric dyes show fair to very good fastness to light and very good to excellent fastness to washing, rubbing, perspiration, and sublimation. © 1998 John Wiley & Sons, Inc.
