する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a splittable conjugate fiber capable of expressing ultrafine fibers having a single fiber fineness of 0.8 denier or less by splitting. More specifically, the present invention relates to a splittable conjugate fiber that is excellent in processability such as passability of a crimping crimp when applying crimp or passability of a card process.

題がある。2. Description of the Related Art Short fibers having a single-filament fineness of 1.5 denier or more are generally used for non-woven fabrics. However, the smaller the single-filament fineness, the higher the flexibility and the better the surface feel.
Attempts have been made to use ultrafine short fibers of 1.0 denier or less. However, there is a problem that the ultrafine short fibers are inferior in the passability in the card process, the productivity is lowered and the cost is also increased.

れている（特開昭６２―１３３１６４号公報等）。In order to solve such a problem, conventionally, splitting type composite fibers made of polymers having a low affinity for each other were used for carding, and then they were split by mechanical impact such as high pressure fluid flow to form ultrafine fibers. A method for producing a nonwoven fabric has been proposed (Japanese Patent Laid-Open No. 62-133164, etc.).

きない。However, the split type conjugate fiber that has been proposed hitherto is such that when the crimp is imparted by an indentation crimping machine or the like, the splitting progresses when passing through the card process, and the expressed ultrafine fibers are produced. Good cardability cannot be obtained because it causes winding around the cylinder or nep generation.

いので、上記問題の本質的解決策とはなっていない。Japanese Patent Publication No. 3-1426 discloses that even if the division progresses at the time of crimping, by applying an oil agent to the newly exposed peeling surface, the post-process passability is improved. However, since it does not suppress the expression of ultrafine fibers and does not suppress the progress of division in the carding process, it is not an essential solution to the above problem.

至った。Means for Solving the Problems As a result of intensive studies for achieving the above-mentioned object, the present inventors have found that a splittable conjugate fiber having a specific amount of a silicon-based oil agent adhered thereto is subjected to post-processing such as a crimping step or a carding step. The present inventors have completed the present invention by finding that the progress of division in the process is remarkably suppressed and, as a result, a good card-passing property is achieved and a nonwoven fabric having a good texture can be stably obtained.

The oil solution is a silicon component of 0.

生の問題を生じるので好ましくない。In the present invention, it is important that the silicon-based oil agent is attached to the splittable conjugate fiber composed of the above-mentioned polymers having a low affinity with each other, and 0.01 to 1.0% by weight as a silicon component. , Preferably 0.02-0.8
Must be attached by weight%. If the amount of the silicon component deposited is less than 0.01% by weight, the effect of reducing the friction between the fiber and metal becomes insufficient, and excessive stress is applied to the composite fiber when applying indentation crimping or during carding. Was
Separation between the components progresses, ultrafine fibers are produced, winding on the cylinder and nep occur, and card passing property is deteriorated, which is not preferable. On the other hand, if it exceeds 1.0% by weight, the friction between fibers is too much reduced, and the entanglement of the web is insufficient, making it difficult to obtain a uniform web, and at the same time, the card passing property is reduced. Further, since the antistatic property is lowered, it is necessary to add a large amount of antistatic agent, which causes a problem of scum generation, which is not preferable.

It may be applied as a silicon-based oil agent used in combination as necessary. At this time, when a wax or mineral oil having insufficient heat resistance is used as the smoothing agent component, it is preferably in the range of 5 to 100% by weight with respect to the silicon component.

Although it is also possible to use, it is not preferable to use one that easily penetrates into the inside of the fiber over time, and therefore it is preferable to use at least a part that is solid at room temperature. In the case of polyester / polyamide and polyester / polyolefin composite fibers, the compounding amount is 100 to 5 with respect to the silicon component.
It is preferably in the range of 00% by weight.

Polyethylene glycol / polypropylene glycol modified polysiloxane and the like are particularly preferable, and as the antistatic agent, it is also preferable to use an alkyl phosphate metal salt having 8 to 12 carbon atoms in combination, or to use a hydrophilic compound such as sorbitan fatty acid ester in combination.

なる。The above-mentioned silicon-based oil agent may be applied at any stage of producing the composite fiber, but it is usually applied after drawing. Among them, the method of applying the composite fiber after stretching and before the crimping is preferable because the progress of division at the crimping step is suppressed. However,
Even when the composite fibers are applied immediately before being cut into short fibers or immediately before the carding process, the progress of division in the card process can be suppressed, and the card passing property becomes good.

の低下を小さくすることができ、特に好ましい。It should be noted that the fact that the silicone-based oil is liquid at room temperature makes it easier for the silicone-based oil to permeate into the peeling surface between different polymers, so that even if the division proceeds in the crimping process, the card process, etc., it is newly expressed. It is particularly preferable that the silicone component permeates into the above surface to reduce the deterioration of card passing property.

ことができる。The splittable conjugate fiber of the present invention described above is made into a web through a card in accordance with a conventional method, and then the splitting of the conjugate fiber into ultrafine fibers and the entanglement between the fibers are performed by needle punching, high-pressure water flow or the like. By carrying out at the same time, it is possible to easily obtain a non-woven fabric made of fine fibers with good quality.

エブを得ることができる。Since a specific amount of silicon component is attached to the surface of the splittable conjugate fiber of the present invention, the friction coefficient between the fiber and the metal is suppressed, and the conjugate fiber is used in the crimping step or the card step. The stress applied to is reduced. As a result, peeling of the heteropolymer interface in such a step is suppressed,
Wrapping of ultrafine fibers around the cylinder and generation of nep are reduced. On the other hand, the friction coefficient between the fibers does not decrease so much, so that the entanglement of the fibers is sufficient and a stable and homogeneous web can be obtained.
