Description of the Related Art Generally, an increase in the amount of oligomers accompanying high-speed spinning of synthetic fibers and heat treatment of synthetic fibers generate oligomers on the fiber surface in correlation with the processing temperature and time, and the dyeing process in the subsequent dyeing process It is known that defects such as uneven dyeing and the like adhere to the can wall of a dyeing machine and cause stain in the can.

難になるなどの欠点を有していた。Conventionally, as a method for removing oligomers from synthetic fibers, there is a method for removing oligomers by adding an oligomer removing agent comprising a surfactant to a reducing washing bath. However, such a method for removing oligomers has a low removal effect. Was not practical. Therefore, a method of adding an oligomer-removing agent to a dyeing bath has been attempted. According to this method, the effect of removing the oligomer is considerably improved. This has the disadvantage that the variation between them also increases. Also, recently, the dyeing bath is made alkaline to remove oligomers and reduce stains in the can. The higher the pH of the dyeing bath, the higher the oligomer removing effect, but the faster the dye decomposition. However, it has disadvantages such as difficulty in dye selection and color matching.

Ｈに左右されることがあるため注意をする必要がある。When the pH is lowered during the treatment, the re-adhesion of the oligomer is promoted. Therefore, a 100% pure solution is preferable. However, the pH before and after the treatment is less than 1.0%, more preferably at least 1.0%. If the aqueous solution is 50% or more, the initial pH is 10 or more and the pH decrease before and after the treatment is within 1.0% regardless of the treatment temperature and the treatment time.
It is preferable to treat with a 0% aqueous solution or more. However, when an oligomer remover is used in combination, the stability of the remover is p

This is a compounded system of an anionic surfactant and a nonionic surfactant, and functions to disperse oligomers and prevent insolubilization. The amount of the oligomer remover used in the treatment is 0.1 to 0.5 with respect to 100 g of alkaline ionized water.
The range of g / l is most effective, and the effect is not particularly improved even if the amount of addition is too large.

差が見られることを確認した。The oligomer in the synthetic fiber obtained in the present invention was measured for the residual oligomer contained in 1 g of the synthetic fiber, and it was found that the oligomer had a remarkable effect as compared with the residual amount of the oligomer in the conventional method. In addition, the surface of the fiber cloth was photographed with a scanning electron microscope, and it was confirmed that a remarkable difference was observed even with the naked eye.

かのいずれかである。Dye spots are caused by oligomers produced by heat treatment being eluted into a dye bath and reattaching to the fiber surface during cooling. This reattachment unevenness appears as unevenness only in a certain light beam, and this is called shadow unevenness. Therefore, it is best to emulsify and disperse the oligomer during dyeing and prevent re-adhesion,
Since the compatibility with the dye and the hue reproducibility pose problems, it is preferable to perform the oligomer removal treatment after dyeing at a temperature that does not affect the hue. In the method of removing oligomers by performing treatment before dyeing, the amount of oligomers is reduced, but oligomers may be generated again at the time of dyeing. Since the number of steps increases, it is not preferable in terms of cost. Therefore,
In order to prevent spots caused by oligomers, either re-adhesion of the oligomer is prevented or the re-adhered oligomer is washed.

A range is preferred. The fiber product thus obtained did not have a decrease in tear strength (TRS1022A-I method), and was able to effectively remove oligomers.
