Monitoring concentration of dope in product manufacture |
摘要 |
Continuous elongate members such as filaments are produced by forming a hot dope of cellulose, amine oxide and water, extruding the dope through a die assembly and precipitating the cellulose to form the bodies and maintaining the concentration of the dope at a predetermined value by monitoring the refractive index of the dope before it is extruded.
