The study examined the use of cationic polymers (Polyethyleneimine and chitosan) in treating fabrics like cotton, wool, and cotton/wool (70/30) to improve their dyeability and printability. The study examined factors such as dye concentration, time, and temperature for the dyeing process. Results showed that all dyed and printed fabrics treated with polyethyleneimine and chitosan increased color strength by significant percentages. Fastness properties, such as washing, rubbing, acidic and alkaline perspiration, and lightness, improved significantly. Fabric roughness, tensile strength, and elongation decreased by about 4-10% for each fabric. Additionally, the dyed and printed fabrics showed high resistance to bacteria and fungi. The study contributed to reducing chemicals used in traditional dyeing processes by a significant percentage, as the dyeing bath contained only the treated sample and dye solution. Furthermore kintic and isothermal study was investigated to explain the behaviour of treated fabrics for dye absorption.
该研究考察了阳离子聚合物（聚乙烯亚胺和壳聚糖）在处理棉、羊毛及棉/毛（70/30）等织物方面的应用，以提高其染色性和印花性。该研究考察了诸如染色过程中的染料浓度、时间和温度等因素。结果表明，所有经聚乙烯亚胺和壳聚糖处理的染色和印花织物的色强度均有显著提高。水洗、摩擦、耐酸碱性汗液及耐光色牢度等性能也有显著改善。每种织物的粗糙度、拉伸强度和伸长率下降了约4-10%。此外，染色和印花织物对细菌和真菌具有高度抗性。该研究有助于大幅减少传统染色工艺中使用的化学品，因为染浴中仅含有经处理的样品和染液。此外，还进行了动力学和等温研究，以解释经处理织物的染料吸收行为。
