まう。(B) Prior Art Conventionally, polyester composite fibers in which two types of polyesters having a difference in intrinsic viscosity, that is, a difference in degree of polymerization are joined in a side-pie-side manner have been widely known. This polynis,
Chill-based conjugate fibers are produced by overcoming the difference in intrinsic viscosity between the two polyester components (as a result, a phenomenon called bending occurs during melt spinning, causing the spun yarn to bend and adhere to the spinneret surface before being cut, resulting in unsatisfactory results). Therefore, the difference in intrinsic viscosity between the two polynis spool components naturally has a limit, but if the viscosity difference is selected within the range that allows smooth melt spinning, it will not be possible to perform smooth spinning. The viscosity difference is too small, resulting in poor crimp performance of the composite fiber.

が認められろ。The yarn physical properties of the obtained crimped filament are as shown in the table, and the titanium catalyst content of the high intrinsic viscosity polyester was made higher than that of the low intrinsic viscosity polyester/aluminum, and titanium oxide was used as a matting agent. If the content of polyester with high intrinsic viscosity is increased, further improvement in crimp performance will be observed.
