抄録

A numerical method is given for calculating asymmetric temperature distribution to fiber axis within a filament quenched by cross air flow in the course of melt spinning. And the results of numerical calculation shown in Fig. 9 are obtained for a special spinning condition.<br>It is shown that temperature distribution of spinning filament can be obtained by measuring that of a model cylinder being cooled by cross air flow under the condition of eq. (14-2). Interval τ_m after of cooling in the model test is connected with distance z from spinneret by eq. (13).<br>The structure (birefringence, density) differentiations across the cross-section of polypropylene and polyester spun fibers are measured and related to the asymmetric temperature distribution of spinning filament.
