摘　　要：为了了解细纱前后档胶辊直径搭配对成纱质量的影响,采用不同硬度、不同直径的前档胶辊,分别配置不同直径的后档胶辊进行纺纱试验。结果表明:直径28.9 mm、邵尔A65度的ME666型前档胶辊,后档配直径差异小的胶辊对成纱质量有利;直径29.7 mm、邵尔A65度的J463型前档胶辊,后档配直径差异大的胶辊对成纱质量有利;直径29.8 mm、邵尔A68度的W 888型前档胶辊,在罗拉中心距不同时,后档胶辊配置有变化。指出:后档胶辊直径大小影响后区对纤维的握持控制能力,纺纱生产中当前档胶辊直径、硬度及罗拉中心距等条件不同时,要注意前后档胶辊直径的合理搭配。To study influence on yarn quality of diameter matching of front top roller and back top roller of spinning frame, spinning test with different hardness ＆ different diameter front top roller and different diameter back top roller was done. The result shows that front top roller of diameter 28.9 mm and hardness A65 can has better yarn quality when matching back top roller of small diameter difference, J463 front top roller of diameter 29.7 mm and hardness A65 can has better yarn quality when matching back top roller of big diameter difference, W888 front top roller of diameter 29.8 mm and hardness A68 has change matching back top roller when ratch is different. The test shows that back top roller diameter can influence back area gripping ability, reasonable matching of front top roller and back top roller is very im- portant in the condition of different front top roller diameter, hardness and ratch.
