玉蚕纤维9.8 tex集聚纱的生产

Production of Silkworm Fiber 9.8 tex Condensed Yarn

探讨玉蚕纤维9.8tex集聚纱的纺纱工艺措施。清棉工序重点控制好纤维回潮;梳理过程优化各部件隔距,合理优选针布;并条工艺控制好后区牵伸和喇叭口径;粗纱工序重点控制好粗纱伸长率,减少意外牵伸;采用集聚纺纱形式,优选纺专器材,纺制的玉蚕纤维9.8tex集聚纱质量指标满足了用户的要求。认为:通过一系列的工艺优化,玉蚕纤维纱的毛羽和强力得到有效改善。

The spinning technology measures of silkworm fiber 9.8 tex condensed yarn were discussed. The moisture regain of fiber was controlled emphatically in cleaning process. Each component gauges and card clothing were optimized in carding process. Back zone draft and diameter of pipe socket were controlled in drawing technol ogy. Elongation of roving was controlled to avoid sudden drafting in roving process. The condensed spinning was adopted. Special spinning components ＆ accessories were optimized. The quality indexes of silkworm fiber 9.8 tex condensed yarn met the requirement of customer. It is considered that the hairiness and strength of silkworm fiber yarn are improved by a series of technology optimization.
