To develop hemp spun silk colored spun yarn on cotton spinning equipment successfully,according to fiber properties, dyed hemp fiber and spun silk were pretreated respectively to increase spinnability. Ratio of raw material blending, waste percentages in picking and opening process were controlled rationally to ensure blending ratio. In drawing and roving process,drafting processing was selected rationally,necessary moisture-keeping measures were adopted to ensure semi-product quality. In spinning process, draft in back zone should be selected rationally to increased yarn quality. Through the series of technology measures,finally quality of hemp/spun silk 50/50 18.2 tex colored spun yarn can reach use demand.%为了在棉纺设备上顺利开发汉麻绢丝色纺纱,针对混纺纤维的性能特点,对染色后的汉麻纤维和绢丝分别进行预处理以提高纤维的可纺性；合理控制投料比及清梳工序中的落棉以保证混纺比；并粗工序合理配置牵伸工艺及采取必要的保湿措施以保证半制品质量；细纱工序合理配置后区牵伸工艺以提高成纱质量.通过一系列技术措施,最终成功纺制出满足质量要求的汉麻/绢丝50/5018.2 tex色纺纱.
