对六个批号粗纱煮漂后的主要化学成分含量及纺成的细纱强力进行了测试。对煮漂后粗纱的主要化学成分与细纱强力进行灰关联分析，分析计算得出煮漂后粗纱中各主要化学成分对细纱强力的关联度。本论文发现煮漂后粗纱中果胶的含量对细纱强力的影响最大。%The main chemical components of flax roving after scouring and bleaching from six bat-ches and the corresponding spun yarn strength were tested in this paper , and grey correlation between spun yarn strength and main chemical components of flax roving was analyzed to calculate the related de -gree of main chemical components on spun yarn strength .We found that pectin content has the greatest influence on spun yarn strength .
