On the other hand, potentially splittable fibers that become side yarns are composite fibers with a multilayer mixed structure made of polymers with poor mutual affinity, and are fibers that can be split by mechanical or chemical treatment during or after processing. be. Such a composite fiber having a multilayer mixed structure and potentially splitting property is a fiber having a known structure in which two or more types of polymers are composited in a parallel multilayer structure or a radial structure in the cross section. Examples of composite fibers that can be mechanically split include those made of a combination of polyester and polyamide; examples of composite fibers that can be split chemically include polyester and polyester with additives such as polyethylene glycol, and sulfoiisotal acid modified fibers. There are also those made in combination with modified polyester such as polyester. In the latter case, a part of the composite fiber is dissolved and divided by alkali treatment.

In producing the special structured yarn of the present invention, it is effective to apply a false twisting process. Specifically, in the false twisting process of the core yarn, excessive supply of side yarns to the heating side is effective. It is done by In this case, if the drawn yarn is used as the core yarn, there is no need to draw it, and the twist of the false twist can be easily transmitted upstream of the false twist heater, making it easier for the side yarn winding yarn to be wound uniformly and to reduce the winding length. Once it is long and wound, it is difficult to unravel, and depending on the conditions, the winding point of the side yarn vibrates on the core yarn, making it possible to create a slub-like yarn with a triple-wound structure. On the other hand, when undrawn yarn or semi-drawn yarn with an elongation of 150% or less is used as the core yarn, the side yarn winding yarn is partially stretched along with the core yarn because the stretching is approximately 1.5 times or less. When the excessive supply rate of the drawing side yarn (wrapped yarn) is small or when undrawn yarn with an elongation of 150% or more is used as the core yarn, which results in a draw ratio of 1.5 times or more, most of the wrapped yarn is As a result, it disappears along with the stretching, resulting in an ordinary bulky yarn, and structural yarns with special winding parts are difficult to appear. In addition, if a drawn or semi-drawn yarn made of polyester with a main chain of polybutylene terephthalate or a composite mixed yarn made by stretching polybutylene terephthalate and polyethylene terephthalate is used as the polymer in the core yarn, a special texture can be obtained. A fabric with elasticity is obtained.

If a low orientation spun undrawn yarn or semi-drawn yarn with an elongation of 150% or more is used as the wrapping yarn, it will be easier to stick and fix the wrapped portion, but it will tend to become brittle, resulting in frequent yarn breakage and fluffing. easy.

In addition, when using mechanically split fibers with a multi-layered cross-section composite type as the side yarns, one part or all of the layers of the fibers tend to split during drawing or false twisting, so the fibers have a denier of a fraction of a denier. As a result, yarn breakage may occur due to fluff and tangles.

In this case, as a countermeasure, it is preferable to apply an oil containing a high molecular weight component of polyalkylene glycol that is effective in preventing the formation of fuzz, or to impart convergence by an entanglement treatment.

The oil agent preferably has a molecular weight of 5,000 or more.
The generation of fuzz can be prevented by using a blended oil with a low coefficient of fiber-to-fiber static friction that contains 5% or more of a polyalkylene glycol compound of o or more, and adding 0.3% or more to the fiber weight. . However, if too many components with high molecular weights are blended, the winding shape during spinning or drawing tends to be poor, and the oil film on the fiber surface becomes excessively protected, making it difficult to stabilize the winding shape due to sticking. Caution is required.

Further, the entanglement treatment for imparting convergence can be performed in any process immediately before spinning, stretching, or winding, and the stronger the treatment, the more stable the process will be even if fuzz is generated.

The yarn of the present invention can also be obtained by splitting the side yarn into fine fibers at the above-mentioned false twisting stage, but the yarn or knitted fabric after the false twisting process can be mechanically rubbed or stamped, or as described above. It can also be obtained by chemically treating the winding portion of the side thread to divide it into thin wires.

A 9-layer oval type as shown in Figure 1 is coated with an oil containing 8 parts of a polyalkylene glycol compound with a molecular weight of 1200 added to 100 parts of a blended oil consisting of 0% nonionic emulsifier, 25% nonionic emulsifier, and 5% anionic antistatic agent. Cross-section of composite fiber drawn yarn (7
5d/24f1 elongation 21%) was used as the side yarn, the overfeed rate of the core yarn was 4%, the number of twists was 2300 times/m, and the heating side was used for false twisting at a heat setting temperature of 190°C. Textured yarn was made by feeding the yarn at a 75% overfeed rate. As a result, the point where the side yarn wraps around the core yarn vibrates, and the side yarn forms a slab with a triple-wound structure over a length of 2 to 5 cm, and the other parts have a special slab-like structure in which the side yarn is wrapped in a single layer. The fibers became structural yarns, and some of the side yarns were divided into fine fibers, but there was little fluffing.
