Cellulose diacetate (CDA) fiber used in cigarette tow is typically spun using a spinneret with triangular shaped cross section. The properties of the CDA fibers obtained by spinning are influenced by the interplay of various parameters, with the pressure drop being one of the most important parameters. In this paper, we have developed a pressure drop model based on the rheological information and...
Chemical fibers are typically spun with a spinneret, whose cross-sectional shape may be round, cross, trilobal, etc. On the contrary, cellulose diacetate (CDA) fibers used as cigarette tows are commonly spun with a regular triangular prism spinneret having a regular triangular cross-section because the cross-section of the spun cigarette tow is Y-shape owing to acetone solvent evaporation in the spinning...
