Even if careful attention is paid to (・force), it is not possible to prevent slight twisting or entanglement between the single filaments when undrawn multifilament is unwound from the package.
There was a problem in that these caused yarn breakage during fiber splitting and inhibited the splitting properties of the synthetic fiber multifilament.

In order to solve the problems of the conventional method, the present inventors investigated a method of directly stretching the spun undrawn multifilament without first winding it and winding it without heating. . According to this method, unlike the conventional method, the unstretched multifilament is not wound into a paso cage and then unwound from the package and subjected to stretching, so that the multifilament is not twisted during unwinding. There will be no entanglement, and the splitting properties should be significantly improved. (Also, unexpectedly, the obtained multifilament had extremely poor splitting properties, with frequent yarn breaks in the separating loom11, and satisfactory splitting could not be performed.) Ta.

Furthermore, the cause of these fusions and entanglements is that the multifilament runs on the roller at high speed, which tends to cause single fiber movement or free movement (single fiber migration) on the roller. On the heat send roller, heat setting occurs at a high temperature, which causes slight fusion between single yarns1, and also causes uneven light overlap between single yarns caused by single yarn microclision. It was discovered that this is due to the occurrence of entanglement between single threads.

Polyethylene terephthalate having an intrinsic viscosity of 0.64 was melt-spun using the apparatus shown in the figure, and then directly stretched without unwinding. At this time, the multifilament is divided into single filaments on an oil ruler (2), and an oil agent is applied thereto.
After running on the collar (9) as groups of 3 to 12 yarn bundles each consisting of 1 to 4 single yarns, the yarns were bundled and wound around a bobbin.

When the yarn bundles are divided into two groups (experiment scrap 6) and on the oiling roller (2), they are divided into single yarns, but on the drawing heat send roller (9), they are bundled into single yarns. An experiment similar to that in the example was also conducted in the case where the fibers were run as one luminous flux group consisting of 12 single fibers (actual test Galois).

As is clear from the table, after dividing into multifilament single yarns [7] and applying oil, it can be divided into single yarns or as a group of multiple yarn bundles consisting of multiple single yarns.
When running on a stretching heat set roller (Experiment/16
1 to 4) have good splitting properties with less yarn breakage during splitting, but when the multifilament is coated with an oil agent without being divided into single yarns (Experiment As, 6) and when the multifilament is divided into single yarns. Even if an oil agent is applied on the drawing heat centerer, when the yarn bundle is run as one yarn bundle group instead of being divided into multiple yarn bundle groups (experiment Δ6
It can be seen that in case 7), there were many yarn breakages during fiber splitting and the fiber splitting properties were poor.
