トラブルは全く生じなくなる。 Next, when changing such a composite spinning system to a single spinning system using only A polymer, it is sufficient to replace it with a distribution block 30 and a spinning pack 32 as shown in FIG. The yarn is spun from the spinning pack 32 through the communication hole 31 of the block 30. In this case, the B polymer will remain in the tube of the heating block 7', but
Since it is thermally isolated from the lower spin block body 1 and the A polymer heating block 7 by the heat insulating material 6, the heating block 7' can be adjusted to an appropriate temperature or solidified and held as it is, unlike conventional melting. Problems such as polymer carbonization and blockage of pipes due to deterioration in the spin block, which occur in spinning devices, do not occur at all.

Conventionally known melt spinning apparatuses are generally used for single polymer spinning and composite spinning, respectively, and there is a problem in that the number of spinning machines increases accordingly. Furthermore, in melt-spinning equipment for composite spinning, it is often difficult to maintain the optimum temperature of multiple types of polymers, and even if it is difficult to spin a single polymer, carbonization of the dormant polymer,
Due to deterioration, problems such as blockage of polymer introduction channels occurred one after another.

It is possible to maintain the polymer at the optimum temperature until immediately before the spinning pack, and even when spinning a single polymer, the heating block part of the resting polymer can be kept in a solidified state by cutting off the heating source and using an appropriate insulating material. Since it is possible to maintain the heating state at an appropriate temperature, there are no problems such as carbonization or deterioration of the dormant polymer.
