弱酸性染料

结果表明，当BCPA含量为8%，选用弱酸性染料，适当控制染色温度和染浴pH值就可获得良好的可染性。

The result shows that 8 % BCPA , weak acid dye , proper temperature and pH value meet good dyeability for polypropylene .

A study of acid dyes ( milling dyes ) (ⅰ)── yellow , red diphenyl-methane acid dyes

活性染料染锦纶色泽较鲜艳，染色牢度尤其日晒牢度较好，且可与中性染料、弱酸性染料拼染，因此，色谱的选择范围较大。

Reactive dyes can impart polyamide fabric brilliant shade , good fastness especially to the sunlight , as well as the good combination with neutral and weak acid dyes .

测定了改性羊毛、羊毛和羊绒的性能，以及弱酸性染料、中性染料、活性染料在改性羊毛、羊毛和羊绒上的上染速率。

The properties of modified wool , wool and cashmere , as well as the dyeing rate of weak acid dye , neutral dye reactive dye to these fabrics were tested .

结果表明：真丝纤维经金属离子修饰后，吸湿性提高：弱酸性染料染色的K/S值有所上升；

The results indicate that , the moisture regain of silk fibers increased after being modified by different metal ions ; the K / S value increased gently when weakly acid dyes were used ;

试验表明，直接染料与弱酸性染料同浴上染的锦棉交织物，其色牢度，匀染性都有较好的效果，且降低能耗，节约成本。

Results show that dyeing process with direct dyestuff and weak acid dyestuff in one bath can impart the polyamide / cotton mixture good colorfastness and levelness , as well as lowered energy consumption and production cost .

实验结果表明，自制的马来酸二酯可随着染色温度的升高，逐步释酸，用于弱酸性染料染色，能减缓染色初期的上染速率，提高匀染性。

The experiments showed that the maleic diesters made by the author could gradually release acid as increasing the dyeing temperature and could retard the initial dye pickup in dyeing to enhance leveling when they were used in dyeing with weakly acid dyes .
