得るものではない。 Conventionally, methods for producing composite fibers have involved the use of homogeneous polymers with different viscosities, homogeneous polymers with different ionizable group contents, single polymers and copolymers, or different types of polymers in a parallel type or core type. It is known that sheath-type joint spinning is used, and for this purpose, each polymer to be joined must be prepared separately, and the brand must be changed depending on the purpose of the composite fiber to be manufactured, making the equipment complicated. As a result, work efficiency also decreases. or,
One type of molten polymer stream is divided into two parts, and a heater is installed in one of the parts to heat and deteriorate the flow. This changes the thermal history of each polymer, giving a difference in the shrinkability of the two polymers, and causing latent crimp. It has also been proposed to produce fibers with properties. However, in such a method, only the thermal history is changed, so even if the difference in heat shrinkage, for example, does not exceed a certain limit, it is not possible to impart antistatic properties, flame retardance, moisture absorption, etc. do not have.

FIG. 1 is a schematic illustration of the method of the present invention, in which a polymer stream 1 is divided into polymer streams 2 and 3, and then a modifier 4 is metered into the polymer stream 2 by a pump 5 in a kneading block A. It is injected through valve 6. The associated polymer and modifier are mixed in a rapid kneader 7.
After being mixed in the spinning pump 8, the mixture is metered in the spinning pump 8, further mixed uniformly in the rapid kneader 9, and sent to the spinning pack 10. On the other hand, in kneading block B, the modifier 4'
Valve 6' is closed to prevent polymer flow 3 from being injected.
The fibers reach the spinning pack 10 without being modified, where they are bonded with modified polymers and spun as composite fibers 11. Incidentally, when it is desired to inject a modifier 4' different from the modifier 4 into one of the polymers, by opening the valve 6', a composite fiber containing two types of modifiers can be produced.

Moreover, since the modifier is rapidly kneaded into the molten polymer immediately before spinning, there is an advantage that there is very little deterioration in fiber properties due to thermal deterioration of the modifier and/or interaction between the modifier and the molten polymer. There is. Therefore, the present invention allows a wide range of organic or inorganic compound modifiers to be mixed with the fiber-forming polymer without impairing its physical properties, making it extremely useful industrially. .

The material that was stretched 38 times in hot water at 70°C and heat treated at 130°C had a fineness of 3.13 d, a strength of 4.06 g/d, and an elongation of 47.2%. The dye exhaustion rate and static electricity generation amount of the obtained composite fiber were 80.3% and +1.4KV (30℃/25%), respectively.
It was hot. Further, no staining spots were found at all.
