棉网喷染无水色纺关键技术

Key technology for waterless color spinning of cotton web with spray dyeing

对梳棉喷染无水色纺纱线关键技术的可行性进行分析并进行研发验证。实践证明:通过对梳棉/喷染装备的设计研发,配置合适的雾化装置、烘干装置和有机溶剂回收装置,并通过对纺纱工艺流程的再造,采用蒸纱方式对无水色纺纱线进行固色,同时对纺纱工艺参数、纺纱专件、专件清洁方式等进行优化调整,实现了棉网喷染无水色纺普梳全棉18.5 tex纱线的生产,并且成纱指标、产品色牢度均达到了预期的开发效果。棉网喷染无水色纺纱线可满足客户对浅色系、花式风格产品的应用需求。

The feasibility of key technologies for waterless color spinning of colored cotton web is analyzed.The results prove that through the design and development of carding/spray dyeing equipment,including the configuration of atomization devices,drying devices and organic solvent recovery devices,and through the transformation of spinning process,fixation of color spun yarns by steaming,and optimization of the spinning process parameters,spinning parts and cleaning methods,the production of 18.5 tex waterless color spinning cotton yarn is realized.The yarn indexes and color fastness can meet the application needs of customers for light color and fancy style products.
