Description of the Related Art Polyester represented by polyethylene terephthalate is widely used as various molded articles such as fibers, films and bottles because of its excellent heat resistance, light resistance and mechanical properties. In order to impart various properties to such molded articles, various functional imparting agents have been conventionally added and blended, and various addition methods have been proposed. For example, taking as an example the case of incorporating a colorant as a functionality-imparting agent,
A method of directly adding a colorant to polyester, blending it in polyester at a high concentration to produce a master chip,
A method of adding this to polyester at the time of molding, or a method of dispersing it in a liquid dispersion medium in advance and adding it to polyester in a liquid state (for example, JP-A-63-11).
7071, JP-A-60-45690, etc.) have been proposed. The method of using a material in which a colorant is previously dispersed in a liquid dispersion medium (a liquid colorant) is easy to handle, there is little contamination during premixing (when the colorant is dispersed in the liquid dispersion medium), and coloring is performed. It has been widely used in recent years because it has a feature that the time required for switching a liquid colorant at the time of manufacturing a molded product is short and that it can be easily compounded at the time of molding a fiber, a film, and other molded products.

If the amount is less than the above, not only the amount of smoke generated when compounded in the molten polyester is increased, but also the compatibility with the polyester is lowered and it becomes difficult to obtain a fiber having less quality unevenness. On the other hand, when it exceeds 4, the viscosity becomes too high and it is difficult to mix the functionalizing agent in advance, and the handling property of the obtained liquid modifier is deteriorated and the quality unevenness of the molded product tends to be large. .

す。The above-mentioned dispersion medium (liquid polyvalent ester compound) must further have a hydroxyl value of 15 mgKOH / g or less. Hydroxyl value is 15mgKOH /
When it exceeds g, when the liquid modifier based on the dispersion medium is added and blended in the molten polyester, the reaction between the polyester and the dispersion medium is likely to occur, and the intrinsic viscosity of the polyester is lowered during spinning, and the dispersion medium is decreased. Smoke generation due to thermal decomposition, contamination of the spinneret and its surroundings become large, and many yarn breakages are accompanied with these, and the physical properties of the obtained fiber deteriorate.

UV absorber, light stabilizer, matting agent, coloring pigment,
Examples thereof include dyes. In particular, when a coloring pigment or dye is blended, in general, even a very slight dispersion unevenness is easily detected as a colored unevenness, but according to the method of the present invention, the liquid modifier is uniformly dispersed in the polyester.

るので好ましくない。The proportion of the functional-imparting agent compounded in the liquid dispersion medium varies depending on the type of agent used and the extent to which the polyester is modified, but usually the dispersion medium 100 is used.
0.1 to 100 parts by weight is preferable with respect to parts by weight. If the blending amount is less than 0.1 parts by weight, the amount of the liquid modifier necessary for modifying the polyester increases, and the mechanical properties of the resulting fiber deteriorate, which is not preferable. On the other hand, if the amount exceeds 100 parts by weight, it becomes difficult to disperse the liquid modifier in the polyester, and it becomes impossible to obtain fibers of uniform quality, which is not preferable.

質斑を生じやすい。The viscosity of the liquid modifier compounded with the function-imparting agent is 2000 poise or less at room temperature because of the handling property and the measurement accuracy when it is added and mixed into the molten polyester.
It is preferably 1500 poise or less.
When it exceeds 2000 poise, not only the fluidity is deteriorated and the handleability is deteriorated, but also the measuring accuracy is deteriorated and the quality unevenness is likely to occur.

で、０．６以上特に０．８以上が好ましい。In the present invention, the polyester to which the above-mentioned liquid modifier is added is mainly a polyester whose repeating unit is mainly ethylene terephthalate, but the third component other than the terephthalic acid component and / or the ethylene glycol component. A small amount (usually 20 mol% or less with respect to the terephthalic acid component) may be copolymerized. Further, a polyester obtained by mixing a small amount of another type polymer (usually 10% by weight or less with respect to the polyester) may be used. The intrinsic viscosity of the polyester is not particularly limited, but the dispersion medium and the polyester may partially react during melt spinning to reduce the intrinsic viscosity of the polyester, or to reduce the mechanical performance of the obtained fiber. Therefore, 0.6 or more, particularly 0.8 or more is preferable.

望ましい。It is not necessary to employ a special method for adding and blending the liquid modifier into the molten polyester. For example, after the liquid modifier is injected and added into the molten polyester before spinning while being measured by a gear pump or the like. , A static mixer, and the like, and then discharging from a spinneret. The addition amount of the liquid modifier here varies depending on the amount of the function-imparting agent blended in the liquid modifier and the required degree of modification, but is usually 100 parts by weight of the molten polyester. On the other hand, the amount is preferably 1 to 11 parts by weight.

It is not preferable because it easily occurs. on the other hand,
If the amount exceeds 11 parts by weight, the mechanical properties of the obtained fiber may be deteriorated and the spinning process may be unfavorable.

減少されるといった効果が発揮されるのである。Although the reason why the modified polyester fiber having less quality unevenness can be stably obtained by the production method of the present invention described above, it has not been clarified in detail.
It is estimated as follows. That is, since the liquid dispersion medium used in the present invention has a molecular structure based on a phenol derivative skeleton having extremely excellent affinity with polyester, it exhibits very good compatibility with polyester and, as a result, functions. The property-imparting agent can be very easily uniformly dispersed in the polyester. Further, since the dispersion medium also has excellent heat resistance, it is less likely to undergo thermal decomposition or react with the polyester at the melting temperature even if it is added to the molten polyester. As a result, problems such as quality unevenness due to the dispersion of the functional property-imparting agent and deterioration of the spinning stability are reduced, and thermal decomposition of the dispersion medium, deterioration of the mechanical properties of the fiber due to thermal reaction, or breakage during spinning. The effect of reducing such troubles is exhibited.
