観を呈しゃすく。Conventionally, many techniques for applying fluid disturbance processing to multifilaments and the like have been proposed and introduced. As examples thereof, fluid-treated non-mm multifilament yarns with different heat shrinkage rates and interlaced yarns of false twisted and crimped multifilament yarns are disclosed. In the above conventional technology, 1. For example, yarns obtained by fluid treatment of non-crimped multifilament yarns with different heat shrinkage rates do not have crimping properties, so they have poor elasticity, stretchability, bulge, etc. in the radial direction, resulting in poor product texture. It is impossible to get out of the fiefment-fix zone. In addition, in the case of an interlaced yarn of a false twisted crimped yarn and a non-crimped multifilament yarn, the false m
The crimped yarn is crimped with the normal number of false twists during false twisting, so it has fine crimps and high elasticity, and has low opening properties, so it has the disadvantage of poor entanglement during fluid treatment. are doing. Therefore, the difference in entanglement with the non-crimped multifilament yarn becomes excessive, and the false-twisted crimped yarn and the non-crimped multifilament yarn are not closely intertwined, resulting in a clear core even if a yarn length difference is provided. The scabbard aK- is quite different. In addition, because the normal false-twisted crimped yarn that becomes Core III has a large degree of deformation in the fiber cross-sectional shape, the difference in gloss between the false-twisted crimped yarn partially exposed on the yarn surface and the non-crimped multifilament yarn is too strong. It has a glossy and heathered appearance that is different from the VILt key tone.

目的と（る芯鞘４１１１１造の複合糸が得られる。As described above, the present invention provides a yarn (thermoplastic synthetic fiber multifilamen) 1c (thermoplastic synthetic fiber multifilament) (hereinafter referred to as Low medical treatment woman 1)
! i-twist yarn) and non-squeezable multifilament yarn (referred to as i-twist yarn).
(hereinafter referred to as non-crimped yarns) are subjected to fluid agitation treatment at the same time.Low-crimped false twisted yarns have coarse single yarn crimps and good opening properties between single yarns, so they are treated with non-crimped yarns. A core-sheath structure can be obtained by providing a certain degree of yarn length difference between the nine yarns with a small difference in entanglement. However, since low-crimp false twisted yarns have inferior entangling properties than non-crimped yarns, they tend to migrate to the sheath when subjected to fluid disturbance treatment such as entangling treatment. Therefore, in the present invention, a sufficient difference in yarn length is provided between the low-crimped false twisted yarn and the non-crimped yarn to form a clear core-sheath structure. 1 supply 4r^(q
6) and the excess supply rate FB (qb) of the non-shrinkable yarn to have a relationship of 5 (%) and perform fluid agitation treatment 4.
Both yarns are fed to the plant, and by combining them in this way, the desired composite yarn with a core-sheath structure of 41111 is obtained.

近づいてクリンプが細かくなり。In Akira Kio, it is necessary to use, as one of the yarns, a low-crimp false-twisted yarn that has been false-twisted to a number of false twists that is about 85% or less of the normal number of false twists shown by the formula +1) above. When it exceeds 85, the properties of the yarn approach those of normal false twisted yarn with a temporary number, and the crimp becomes fine.

フイクな光沢、風合を損うので好ましくない。This is not preferable because the opening property is poor (and the difference in entanglement with the non-twisted yarn due to fluid agitation treatment becomes excessive).The lower limit of the temporary number is not particularly limited, but when the tension becomes low, it is undesirable. The lower limit of the number of false twists should be about 50, as the properties of the non-stretched yarn used tend to be poor, and the elasticity and elongation in the radial direction of the composite yarn tend to be poor, and the flexibility and resilience tend to decrease. On the other hand, if this difference is less than 596, the yarn seat length of both yarns is too small, and during fluid agitation treatment, the low crimped false twisted yarn moves to the @ side and does not form a clear core-sheath structure, resulting in a low crimped false twisted yarn. This is not preferable because the exposed ratio of the twisted yarn on the yarn surface tC increases and dances, impairing the V-luxury luster and texture.

いて説明する。Next, the characteristics and effects of the uniformly plied yarn obtained by the present invention will be explained.

合糸表面に露出しても。As mentioned in item 11, since the core and wire are low J18 shrinkage false twisted yarn, the fabric has an excessive porium feel like when the false twisted yarn processed with the usual temporary number is placed on the stone side. It is a silk-like material that does not have a loose feeling and has a flexible texture and has greater elasticity and elongation in the radial direction than the non-crimped filament. Become. Furthermore, even if some of the single yarns of the 6-fold low-stretch false twisted yarn are exposed on the surface of the composite yarn.

阻占Ｃることがない。Since it is a false-twisted yarn with low false twisting and loss, the degree of deformation of the cross-sectional shape of the low-crimp false-twisted yarn is small, and it exhibits a gloss similar to that of non-twisted filament, so it has a silk-like shine. There is no obstruction C.
