高速加工双收缩丝的新概念

New high-speed concept for manufacturing bi-shrinkage yarns

介绍了巴马格(Barmag)公司与RMIT合作开发出的加工双收缩丝的新方法。加工这种丝的传统工艺大都采用低速技术,所加工的双收缩长丝是2根或2根以上具有不同沸水收缩性长丝的机械组合。巴马格公司利用一种改良的复合工艺及巴马格公司Evospeed技术加工双收缩丝。该工艺的设备系统可在一道工序中进行纺丝及POY与HOY或其他特殊丝组合的直接复合,具有很好的成本效益,最高速度可达4800m/min。这种工艺可将双收缩丝目前的生产成本降低至少一半,使这种“新合纤”具备更好的市场竞争力。

Barmag - in development co-operation with RMIT - has now introduced a novel new method of producing bishrinkage yams. Most of the processes used were slow-speed technologies in which bi-shrinkage filament yams are mechanical combinations of 2 or more different boiling-water - shrinkage property yams. The newly-developed process has now been validated for manufacturing bi-shrinkage yams using a modified combined process in conjunction with Barmag＇s Evospeed technology. This system permits the spinning and direct combination of POY and HOY, or any other special yam combination, in a single step. This process is highly cost efficient and at very high speeds in excess of 4 800 m/min. The process has the potential to reduce the current costs of production of these yams by at least half and made the yam more competitive in the market.
