丝维尔与Outlast染色性能比较

Dyeing properties comparison between Siwear and Outlast

丝维尔和Outlast纤维均为智能调温纤维。前者为国产．后者为进口。针对Outlast莫代尔混纺氨纶面料、丝维尔莫代尔混纺氨纶面料、0utlast纯纺氨纶面料和丝维尔纯纺氨纶面料，采用正交实验方法，分别就汽巴中温型双活性基活性染料黄S-3R、蓝S—GL和深红S—B分别上染这4种面料的染色性能进行了对比分析。结果表明，0utlast、丝维尔以及莫代尔这3种纱线的染料上染率差异性不大，可混纺染色。极差分析显示，在相同条件即染液1％，浴比1：10，螯合剂1g／L下，上染这4种面料的最佳温度和最佳助剂用量：黄S-3R温度70℃，元明粉40～50g／L，纯碱10g／L；蓝S—GL为温度60℃，元明粉40g／L，纯碱10g／L；深红S—B为温度60℃，元明粉30～40g／L，纯碱10g／L。染色后，这4种面料均具有优异的干湿耐摩擦牢度和皂洗牢度．达到4～5级或以上。

Selecting Outlast/Modal/polyurethane fabric,Siwear/ Modal/polyurethane fabric,Outlast/polyurethane fabric and Siwear/ polyurethane fabric,setting the pretreatment temperature at 195 ℃,applying hydrogen peroxide solution to make the bleaching and taking the orthogonal experimental method,this compares the dyeing properties of these four fabrics when being dyed with ciba medium temperature reactive dye-Yellow S-3R,Blue S-GL and dark Red S-B.The results show that the dye up-take sequence from high to low is Siwear,Outlast and Modal,but the difference is not big and dyeing can be applied to the blended fabric.Range analysis shows that under the same conditions of concentration of 1%,bath ratio of 1:10 and chelating agent concentration of 1g/L,Yellow S-3R's optimized dyeing technology is that: the dyeing temperature is 70 ℃,the concentration of sodium sulfate is 40～50 g/L,and the concentration of soda is 10 g/L;Blue S-GL's optimized dyeing technology is that: the dyeing temperature is 60 ℃,the concentration of sodium sulfate is 40～50 g/L,and the concentration of soda is 10 g/L;Dark Red S-B s optimized dyeing technology is that: the dyeing temperature is 60 ℃,the concentration of sodium sulfate is 40 g/L,and the concentration of soda is 10 g/L.Furthermore,the four kinds of dyed fabrics show excellent dry and wet fastness to rubbing and soaping about Class 4 to 5 or even above.
