本文采用激光粒度仪LS3320测定分散染料C.I.分散蓝79高温处理后的平均粒径变化以衡量染浴中高温分散稳定性。实验结果证明:分散剂MF和木质素磺酸盐在提高其高温分散稳定性上具有协同作用。阴/阴或阴/非离子表面活性剂复配物的使用可以改善C.I.分散蓝79高温稳定性,浊点较低的非离子表面活性剂用量较高,会对提高分散染料的稳定性有负面影响。 相似文献

本文制备了不同浓度的阴离子表面活性剂或非离子表面活性剂—分散染料(C.I.分散蓝79)水分散体系,并以沉降度作为分散体的稳定参量,动电位为颗粒电结构参量,研究了无机电解质对这些分散体的稳定性和动电性质的影响。动电性质实验和沉降实验良好符合。结果表明,较低浓度的无机电解质能辅助扩散双电层的建立从而增加分散体稳定性;当其浓度超过某临界值时又会压缩双电层从而成为不稳定因素。尽管电解质浓度增大使表面活性剂在染料颗粒表面吸附量增大,但电解质对双电层的直接影响始终占主导地位。 相似文献

本文研究了C. I. 分散橙30与C. I. 分散橙76相混合(分散黄棕SE-2RLM)的增效效应。通过熔点图、上染量和提升力的测定,确证了分散黄棕SE-2RLM存在增效效应。分散黄棕SE-2RLM为一具有最低共熔点的共熔物。最低共熔组成的分散黄棕在聚酯纤维上具有最大的上染量,该组成的分散黄棕在原染料强度、提升力、热熔曲线、pH依存性和升华牢度等。方面明显地优于两组份染料。或两组份染料之一。 相似文献

The hemolytic properties of polyoxyethylene-type nonionic surfactants were investigated in the concentration range of 0.1–5.0
wt/vol%. The effects of hydrophiliclipophilic balance, molecular weight, chemical structure and solubilizing ability of the
nonionic surfactants in hemolysis are discussed. Bulky surfactants with three or four alkyl chains in their molecules, which
show low solubilizing ability of lipids, were the least likely to induce hemolysis. Morphological observations of erythrocytes
by video-enhanced microscopy showed that linear surfactants induce the formation of spherocytes and cause hemolysis, whereas
bulky surfactants induce only morphological changes from discocytes to spheroechinocytes. 相似文献

为了研究C.I.分散蓝14热转印棉织物皂洗变色的影响因素,探讨了架桥剂、温度、水和皂液浓度对热转移棉织物上C.I.分散蓝14颜色的影响,同时结合色度参数和反射率曲线考察了棉织物上C.I.分散蓝14皂洗变色现象。结果表明皂液浓度对热转印棉上C.I.分散蓝14皂洗后的颜色变化具有一定的影响,主要影响因素为水和皂液的温度,且颜色的变化随着温度的升高而增大;架桥剂本身对颜色的变化无显著影响。 相似文献

Cellulases are widely applied in textile finishing, such as for the removal of protruding surface fibrils to reduce pilling propensity and to achieve the worn‐out look in denim garments. The main drawback of enzymatic denim processing is the back‐staining of indigo, which reduces the desired blue–white contrast. Alongside an accurate selection of the type of cellulase or vigorous post‐washing of the garments, the simultaneous application of auxiliaries in the enzymatic treatment may help to reduce back‐staining and improve cellulase efficiency. In the present work, the influence of additives such as surfactants and dispersing agents on indigo adsorption and on the treatment of an undyed cotton fabric with Hypocrea jecorina cellulases was investigated. Indigo adsorption was successfully reduced by more than 75% with ethoxylated nonionic surfactants at concentrations below 0.2 g l?1. The weight loss of cotton fabrics after 120 min treatment was significantly increased with nonionic surfactants and polyvinylpyrrolidone. It could be further shown that protein adsorption on the cotton fabric decreased with the increasing concentration of the additives, while the nonionic surfactants were more efficient than the polyvinylpyrrolidone. Adsorption of a complete cellulase mixture was affected differently by the surfactants than by an exoglucanase‐free endoglucanase‐rich preparation. 相似文献
