The colours and patterns of coloured textiles are usually obtained via dyeing or printing processes. However, these processes consume large amounts of electricity and cause water pollution, which affects the ecological environment. The hand feel of dyed fabrics is superior to that of printed fabrics. Three‐channel rotor spinning is a highly flexible, adaptable and sustainable method for producing coloured textiles by blending precoloured fibres during the spinning process. Additionally, the process requires approximately half the water required for fabric dyeing or printing. Herein, the colour characteristics, as well as the advantages, of the coloured textiles produced by the new method are demonstrated. Three types of Stearns‐Noechel models are modified to describe the relationship between the blending ratios and resulting textile colours. The colour‐matching accuracy is high. As demonstrated by the results, the three‐channel rotor spinning method can effectively promote coloured textile engineering.

色彩匹配，实现彩色纺织品的智能和可持续纺丝

彩色纺织品的颜色和图案通常是通过染色或印花工艺获得的。但是，这些过程消耗大量电力并造成水污染，从而影响生态环境。染色织物的手感优于印花织物。三通道转杯纺是通过在纺纱过程中混合预染纤维来生产有色纺织品的高度灵活，适应性强和可持续的方法。另外，该过程大约需要织物染色或印花所需水的一半。在此，对通过该新方法制造的着色纺织品的颜色特性以及优点进行了说明。修改了三种类型的Stearns-Noechel模型，以描述混合比与所产生的纺织品颜色之间的关系。配色精度高。结果表明，三通道转杯纺方法可以有效地促进有色纺织工程。
