摘　　要：为降低基于棉纺系统的棉/大麻混纺纱在纺纱过程中造成的大麻损耗,在对棉纺前纺系统进行设备改造的基础上,设计了预处理棉与大麻普梳混纺、预处理棉与预处理大麻普梳混纺、预处理棉与大麻精梳混纺3套方案,通过其与原棉纺系统纺制的棉/大麻混纺纱的损耗与品质对比,确定了减少损耗,提高制成率的优化工艺方案:预处理棉与大麻精梳混纺方案,即原棉经过预处理后与大麻纤维混合,经过进行机器改造后的开清棉、梳棉、精梳设备,最终纺制成细纱。该工艺在原有工艺的基础上损耗降低16.7%,纱线条干略有下降但在可以接受的范围之内,纱线强度没有明显差别,制成率由原来的65%提高到了81.7%,降低了大麻产品的成本。In order to reduce the loss of hemp fiber of cotton/ hemp blended yarns on cotton spinning systems, 3 experiments are designed： a pretreated cotton and hemp carding blend system, a pretreated cotton and pretreated hemp carding blend system and a pretreated cotton and hemp combing blend system, based on the equipment modification of cotton spinning systems. By comparing the loss and quality of the cotton/hemp blended yarns of 3 designed systems with original spinning systems, the optimal low-loss process derives from the pretreated cotton and hemp combing blend system, i. e. , yarns are spun by preterating the raw coton and mixing with hemp on modified opening, cleaning, carding and combing devices. The losses reduce by 16.7%, yarn evenness declines slightly but within an acceptable range and the tensile fracture properties of yarns have no significant difference. The pull rate increases from 65% to 87.1%, reducing the cost of hemp products.
