空调系统为涤纶长丝提供了必要的生产环境。但目前国内空调设计还存在一些问题,例如:前纺卷绕间及后纺加弹间的空调送风量过大,引起飘丝;卷绕间空气压力大于二层纺丝间空气压力发生投丝困难;纺丝间纺丝箱处温度过低导致自喷丝板喷出的丝束质量不合乎要求。因此不仅增加了初投资和运行管理费用,而且还影响正常生产。本文仅就笔者近几年设计过的化纤厂及测试结果,谈几点意见。
Air conditioning system for polyester filament provides the necessary production environment. However, there are still some problems with the design of air conditioners in China at present. For example, the air volume between front spinning and rear spinning plus air-conditioning is too large, which causes the floating of air. The air pressure between windings is larger than the air pressure between two spinning layers Difficulty spinning; too low a temperature at the spinnerets in the spinneret results in unacceptable quality of the tow emerging from the spinneret. Therefore not only increased the initial investment and operation and management costs, but also affect the normal production. This article only on the author in recent years, the design of the chemical fiber plant and test results, talk a few comments.
