Polyester is the most used of the synthetic fibers used in the textile industry. Nonetheless, due to its structure, the use of only disperse dyes for dyeing creates a significant weakness in its coloring. In this paper, the utilization of reactive and acid dyes in the dyeing of polyester after chemical modification with guanidine-based polymer is investigated. The dyeing of poly(ethylene terephthalate) (PET) fabrics with reactive and acid dyes was succeeded via modification with guanidine-based polymer. The effects of this polymer on disperse dyeing were also investigated. The effect of various parameters such as temperature, duration, pH, different amounts of salt and alkaline, the different dyes and processes were investigated for modifying and dyeing PET. The optimum parameters for reactive dyeing were found to be modification and dyeing in the same bath at 100° C for 60 minutes without salt and alkaline, for which the obtained color strength (12.87) was higher than that of conventional disperse dyeing with carrier (10.43). In addition, polymer modification at 130° C for 60 minutes before disperse dyeing provided higher color depth (24.39) than dyeing of PET by the conventional disperse high temperature method (22.48). Color fastness in laundering and the perspiration of modified and reactive dyed fabrics reached good to excellent levels (4/5). The modified and dyed samples were characterized using Scanning Electron Microscopy and Fourier Transform Infrared. Tensile tests and flexural rigidity tests for modified and reactive dyed samples were also conducted. The results indicate that the quality of the beginning material was not degraded after being modified and dyed.

有机碱诱导的聚对苯二甲酸乙二醇酯织物的染色性能

涤纶是纺织工业中使用最多的合成纤维。尽管如此,由于其结构,仅使用分散染料进行染色在其着色方面造成了显着的弱点。本文研究了活性染料和酸性染料在胍基聚合物化学改性后的聚酯染色中的应用。通过胍基聚合物的改性,成功地用活性染料和酸性染料染色聚对苯二甲酸乙二酯(PET)织物。还研究了该聚合物对分散染色的影响。研究了各种参数(如温度、持续时间、pH 值、不同量的盐和碱、不同染料和工艺)对 PET 改性和染色的影响。发现活性染色的最佳参数为改性和同浴染色 100°C 无盐无碱染色 60 分钟,获得的色强度(12.87)高于常规有载体的分散染色(10.43 )。此外,在分散染色前在 130°C 下进行 60 分钟的聚合物改性提供了比通过常规分散高温方法染色的 PET (22.48) 更高的色深 (24.39)。改性和活性染色织物的水洗色牢度和汗渍色牢度达到良好至极好的水平 (4/5)。使用扫描电子显微镜和傅里叶变换红外对改性和染色样品进行表征。还进行了改性和活性染色样品的拉伸试验和弯曲刚度试验。
