摘　　要：通过对传统的FA506型环锭细纱机采取三罗拉异形管网格圈型紧密纺技术改造,探讨了集聚负压对紧密纱捻度的影响。结果表明,在其他纺纱条件相一致的情况下,对同一线密度的管纱而言,用集聚装置纺制紧密纱其捻度比同锭上纺制的普通环锭纺纱要大,紧密纱的附加捻度与吸风负压的大小成正比关系,与纱支的高低成反比关系。By taking three-roller grid circle compact spinning transformation on the traditional FA506 ring spinning frame,the influence of condensing negative pressure on compact-spun yarn performance was researched.The results showed that the twist of compact-spun yarns were larger than the ring-spun yarns′in the same spinning conditions and with the same linear density of the yarn.The value of additional twist is proportional to the value of the negative pressure,and is inverse ration with the linear density of yarn.Generally,the value of additional twist reduced with increased compact-spun yarn count.
