载体复配对涤纶分散染料常压沸染的影响研究

将N-正丁基邻苯二甲酰亚胺、自制苯酯助剂和WLS联合应用于涤纶常压沸染染色中,结果表明:N-正丁基邻苯二甲酰亚胺和苯酯助剂具有增塑涤纶的作用,而苯酯助剂和WLS具有阳离子结构,可促进分散染料阴离子胶束吸附涤纶,这3种助剂按适当比例复配有协效作用。复配载体应用于涤纶织物分散染料常压染色,染料上染百分率、染色织物表观深度、耐摩擦牢度及耐皂洗牢度与传统高温高压染色工艺效果相当。

涤纶纤维用分散染料匀染剂FZ-802的研制与应用

涤纶及其混纺的纤维、纱线、织物在用分散染料高温高压染色时,常因分散染料的匀染性差,升温速度快而造成染色不匀。为此,染色时必须采用有效的匀染剂。根据匀染机理,匀染剂可分为三种类型:1)载体;2)对分散染料有亲和力的表面活性剂;3)对涤纶纤维有亲和力的表面活性剂。用作匀染剂的表面活性剂有非离子型、阴离子型两大类。分散染料的匀染剂的匀染能力,是其移染性能、分散性能、缓染性能的综合反映。此

分散匀染剂XFR-101的性能和应用

前言涤纶用分散染料染色,常需借助分散性、匀染性良好的助剂,以达到匀染效果。用于涤纶染色的助剂品种国外较多。近年来,国内也相继生产了涤纶染色用助剂,如上海的BOA、GS,南京的FZ-802、涤美盐,常州的高温匀染剂-10等。由于分散染料中某些色种如棕、雪青(茄紫)、深蓝等容易产生色花、色点,较为难染,工厂中一般仍使用进口助剂。为了解决难染色种的染色,提高染色质量,减少助剂的进口,节省外汇,我所于1981年4

Neutral dyeing of wool and wool/polyester blend fabrics using sulphatoethylsulphone reactive‐disperse dyes

Two models of temporarily anionic sulphatoethylsulphone reactive disperse dyes were applied to wool, polyester and wool/polyester blend fabrics at different dyeing pH. Maximum exhaustion values and colour yield were observed at pH 7. The results showed that reactive disperse dyes containing bis‐sulphatoethylsulphone reactive groups were more convenient for neutral dyeing of wool and wool/polyester blend fabrics if compared with a dye containing a mono‐sulphatoethylsulphone group. Excellent to very good wet fastness properties on all dyed fabrics were achieved.

Dyeing and finishing of lyocell union fabrics: an industrial study

Lyocell union fabrics, namely lyocell/silk and lyocell/polyester fabrics, were woven in different fabric constructions and dyed with reactive dyes, acid dyes and a disperse dye. The resulting dyed fabrics were given a resin finishing treatment and their wash fastness was measured. With appropriate dye selection and control of dyeing conditions, some bright solid shades and effective cross‐dyed shades were obtained. The dyed and finished fabrics had a smooth, lustrous handle, ideal for lightweight garments.     

The Development of Dyes and Methods for Dyeing Polyester

Early work on the dyeing of polyester fibre showed that only dyes of very low aqueous solubility had substantivity for the fibre, and that for dyeing at the boil without a carrier only the smallest molecular weight disperse dyes, and selected azoic combinations, had sufficiently high dyeing rate to give adequate colour yield in a practicable time of dyeing. The development of carriers for dyeing at the boil, and of machinery for batchwise dyeing under pressure at temperatues up to 140°C, extended the range of suitable dyes to those of lower dyeing rate but higher heat–fastness properties. As an alternative to exhaust dyeing, polyester may be dyed with disperse dyes by padding followed by dry heat fixation at temperatures up to 220°C, and this method has found its main commercial application in the continuous dyeing of polyester–cellulosic blend fabrics. The development of new disperse dyes has followed these trends in application methods, and the proportion of available dyes having higher heat–fastness properties has steadily increased from about 1950 onwards. Improvements have also taken place over the same period in the physical properties of the dyes, to meet the increasingly severe demands on dispersion properties imposed by the newer dyeing methods.     

Novel hydrolysable azo disperse dyes based on N‐ester‐1,8‐naphthalimide: dyeing of polyester–cotton blends

The dyeing of polyester–cotton blends with new alkali‐hydrolysable azo disperse dyes based on N‐ester‐1,8‐naphthalimide was investigated. Polyester–cotton blend fabrics were dyed using both one‐ and two‐bath methods. Dyes 3 and 4 offered lower colour yield on polyester using the one‐bath method. For the rest of the dyes, employing either the one‐ or two‐bath method resulted in a similar colour yield on polyester fabric. The results for fastness properties and colour yield of the dyeings showed that the dyes were suitable for dyeing polyester–cotton blends using the one‐bath method. The kinetic study of hydrolysis of the dyes in alkali media obeyed the pseudo first‐order reaction rate.     

One‐step dyeing of polyethylene terephthalate fabric,combining pretreatment and dyeing using alkali‐stable disperse dyes

In the conventional dyeing process, polyester and its blended fabrics are usually dyed in a weak acidic medium. In order to reduce cost and improve production efficiency, a new dyeing method – one‐step dyeing of polyethylene terephthalate fabrics, combining pretreatment and dyeing in alkali conditions – was investigated. The alkali‐stable disperse dyes Red 900, Red 902, Yellow BROB and Blue 825 were used to dye polyethylene terephthalate fabrics. The dyeing properties of polyethylene terephthalate fabrics in the case of one‐step dyeing at various pH values or sodium hydroxide concentrations were discussed in terms of colour yield, colour parameters and fastness. The performance of one‐step dyeing using alkali‐stable disperse dyes was excellent. The dyed fabric had good fastness. Wet processing could be combined and shortened. One‐step dyeing of polyethylene terephthalate fabrics could reduce the consumption of water and energy and improve production efficiency. One‐step dyeing of polyethylene terephthalate has potential application in cleaner textile production.
