The multicolored bulky yarn described in Japanese Patent Publication No. 58-37403 can be produced by mixing a colored bed colored with a pigment or a pigment masterbatch and a raw resin in a desired ratio, or by mixing a pigment and a raw resin powder. The bulky fibers are obtained by a convenient method such as mixing, and the heterochromatic nature of the bulky fibers is not only caused by the fact that they are colored differently, but also by the fact that they have different hues when dyed after being manufactured as bulky fibers. Differences in coloring properties include the concentration of the same type of dyed sheets, differences in the type of dyed sheets themselves, and differences in the type of polymer (for example, polypropylene). and nylon), and even the same polymers have different coloring properties depending on their fineness.

The pleochroic bulky fiber consists of three types of polyamide fibers classified as A, B, and C. Polyamide fibers A with NH2 end groups from 6.9X10' mol/g to 8.2X10" mol/g are different from other polyamide fibers B and C with NH2 end groups less than 6.9X10" mol/g. The color tone after dyeing with acid dyes is not clear, and if the NH2 terminal group exceeds 8.2X10-5 mol/g, the polymerization time to achieve a high degree of polymerization becomes long, resulting in extremely poor productivity. However, contamination of the spinneret frequently occurs during spinning, resulting in poor spinning properties and the quality of the obtained fibers cannot be maintained at a constant level.

If the number of 2-terminal groups is more than 5.1×10' mol/g, the same color difference, that is, the difference in shade between polyamide fibers A and the above-mentioned polyamide fiber A will not be clear.

If the SO3Na terminal group exceeds 5.0 x 10-'' mol/g, not only will the polymerization time in the polymerization step to achieve a high degree of polymerization become long, but also the dispersion of titanium oxide added to the polyamide fiber as a fader will be difficult. The titanium oxide is prevented from being spun by the filter in the foreign matter filtration zone of the spinning process, causing titanium oxide dispersion unevenness in the spun polyamide fibers and clogging of the filter. The internal pressure increases extremely.Therefore, it is necessary to frequently replace the filter in the foreign matter r retreat zone of the spinning process, which is undesirable from both quality and productivity points of view.The above-mentioned polyamide fibers A, B and C
are individually spun, drawn, and then aligned and combined. The spun polyamide fibers are subjected to a first tensioning treatment at a stretch rate in the range of 2 to 12% at which stretching is not substantially performed in the first tensioning region.

If the stretch rate in the first tensioning area is less than 2%, the heat treatment with the preheating roller described later will be weak, and it will be difficult to crimp during the crimping process in the fluid treatment area, and the Also, crimp spots in the length direction tend to occur, which is undesirable.

On the other hand, the stretch rate in the first tension application region is 1

The polyamide fiber that has been subjected to the first tensioning treatment is then wound around a preheating roller heated to 150 to 200°C to undergo a preheating treatment. By performing the preheating treatment, it becomes possible to crimp the polyamide fibers in the next step extremely uniformly.

When performing preheating treatment, the surface temperature of the roller should be set to 15%.
Adjust to a range of 0 to 200°C. When the surface temperature of the roller is lower than 150°C, sagging or loops are less likely to occur in 1 ml of polyamide cod when crimping is applied in the next step;
If the temperature is higher than 00°C, the single yarns may fuse together when crimping is applied in the next step, and if this fused portion occurs, the physical properties of the polyamide fiber in the length direction will be extremely non-uniform. Become.

When the temperature of the steam in the fluid treatment zone is lower than 200°C, it is difficult to fix the slack and loops formed in the polyamide fibers, and when tension is applied by the second tension applying device in the subsequent process, the slack and loops are difficult to fix. Loops may disappear and good bulky fibers may not be obtained. Furthermore, if the temperature of the steam in the fluid treatment area exceeds 260°C, some of the single filaments forming the polyamide fibers may fuse to other single filaments or disturb the molecular orientation of the single filaments. This may prevent the quality in the direction from becoming extremely uniform.

The bulky fibers that have been subjected to the relaxation treatment in the above-mentioned Olverfeed zone are subsequently guided to the second tensioning zone, where they are subjected to a second tensioning treatment with a stretch rate of 10 to 50%. By setting the stretch rate to 10 to 50%, the loops and slacks of the bulky fibers formed in the fluid treatment zone and the overfeed zone are aligned. When the stretch rate is less than 10%, the loops and slacks of the bulky fibers in the length direction of the polyamide fibers are not aligned, resulting in uneven loops. Furthermore, when the stretch rate exceeds 50%, the loops and slacks formed in the fluid treatment area and the overfeed area are fully stretched, resulting in a decrease in bulkiness6. The aligned bulky fibers are subsequently guided to an air entanglement treatment zone.

Although the air pressure varies depending on the shape of the air entangling nozzle, 5 to 9 kg/cm"' is preferably used.

By setting the overfeed rate to 1 to 5%, the individual filaments forming the bulky fibers are intermixed and tightly bound bundles are alternately formed approximately periodically. If the overfeed rate is less than 1%, the opening of the yarn in the air entangling nozzle may be poor, the single yarns may not be mixed well, and the entangling may occur. On the other hand, when the overfeed rate exceeds 5%, new slack occurs, and this slack tends to become a single yarn that is free and not mixed with other single yarns.
