浮色

用于染色后皂洗可提升浮色洗净效果。

Scaling ; for dyeing soaping enhance floating color wash effect .

讨论了复色漆产生浮色发花的几种原因及解决方法。

Initiation and solution of floating existing in color paint are discussed .

结果表明，HY具有较强的洗除浮色的能力和优异的防沾色能力，可将织物的摩擦牢度提高0.5~1.5级，从而满足客户对色牢度的要求。

The results showed that HY had powerful wash-off ability for lose dyes and excellent anti-staining effect . That would help to enhance rubbing fastness of textiles by 0.5 ~ 1.5 grades to meet the customers ' requirement .

实验结果表明，添加PVP配制的防沾色剂对防止印花织物白地沾污具有一定的效果；PVP能有效去除活性染料染色后的浮色染料，提高活性染料染色后的皂洗效果。

The experiments showed that the addition of PVP to stain-proofing agents resulted in some degree of anti-staining effect on the white background of the printed fabrics , and PVP could remove effectively the loose color in the reactive dyeing to increase the soaping effect in reactive dyeing .

分散染料染色涤纶织物去除表面浮色时，常用保险粉（Na2S2O4）和烧碱进行还原清洗，此法在深色涤纶织物上的清洗效果不理想。

Reductive cleaning is usually used with hydrosulfite ( Na2S2O4 ) and caustic soda to remove surface loose colors from polyester fiber fabrics dyed with dispersal dyes , but this method is not satisfactory on the deep dyed fabrics .

酶体系是通过破坏染料的发色体而达到去除浮色的目的。

The mechanism was that enzyme system destroyed the chromophore of dyes .

涂料的浮色发花

Floating and asymmetry in color in coating producing or using

在皂煮中加入螯合分散剂能有效地去除浮色。

Unfixed dyes could be removed with chelate in boiling .

摩擦牢度降低的主要因素，是未上染的浮色染料在纤维上形成聚集体和染料结晶，若将它们去除，就能提高摩擦牢度。

Main reason for poor color fastness to crocking is the unfixed dyestuffs which form aggregation and crystalline .

如在制卡和会员卡制息历程洋补充不稀释剂后，浮色发花又会再次呈现。

If , on the business card printing and membership card manufacturing process after adding diluent , and floating and appear again .

试验结果表明，壳聚糖浸渍处理棉织物后再染色，浮色少、色泽稳定、摩擦牢度较高。

As a result , the dyed fabric pretreated with chitosan featured less loose color , stable color and higher color fastness to rubbing .

然而，由于活性染料在染色过程中发生水解而降低其上染率，另外由于水解染料对纤维的亲和力增加，致使染色织物表面会产生一定量的浮色，必须通过后水洗工序去除。

However , hydrolysis of this dye during dyeing decreases the dyeing efficiency . Additionally , substantively of hydrolyzed dyestuff increases the duration of washing processes realized after dyeing .

分析了还原清洗、热定形温度、柔软整理对涤纶织物色牢度的影响程度，结果表明：还原清洗能有效去除染色后涤纶织物表面浮色，提高织物色牢度；

The conclusion is that the loose color of the surface of dyed polyester fabric can be effectively removed by reduction clearing , and the color fastness was improved ;

并对涤纶碱性染色时染料的移染性、前处理退浆程度对染色质量的影响、纤维表面浮色量和纤维表面结晶低聚物量作了分析。

The migration properties of disperse dyes , the influence of residual sizes on dyeing , and the amount of dyes and oligomers on polyester fibre surface are also analysed .

为了防止印花织物的白地和白花沾色现象，提高印花织物的色泽鲜艳度和皂洗牢度，织物印花后必须使用净洗剂进行皂煮，以去除浮色及浆料。

The printed fabric must be employed soap boiling with detergent to get rid of the size and scum to avoid the tarnishing and improve the colour brightness and soaping fastness .
