Description

The present invention relates to a cleaning agent composition and a cleaning method using the cleaning agent composition.

Dyeing of polyester fibers is generally performed by immersing the object to be dyed with a disperse dye in a weakly acidic region under high temperature and high pressure of 100 to 150 ° C. after sufficient refining treatment. At that time, various problems occur.

Regarding the scouring treatment of polyester fibers, if the scouring is insufficient or unrefined, the fiber oil agent adhering to the object to be dyed reduces the dispersibility of the disperse dye, so that the specifications of the disperse dye are likely to occur. , Problems such as stains on dyed products and contamination of cans of dyeing machines occur.

Further, in recent dyeing processing, in order to meet various demands, there is a tendency for a wide variety of products to be made in small lots, and the processing cost is rising. Therefore, the machining process is being shortened or simplified in order to reduce the machining cost. In particular, when considering the improvement of productivity and energy saving, measures have been taken to simplify or omit the refining process and the cleaning process. Therefore, the fiber oil and the like that should have been removed in the scouring process enter the dyeing process while remaining on the object to be dyed. In this case, the specifications of the disperse dye are particularly likely to occur, and the dyed object is stained or dyed. Problems such as contamination of the can body of the machine have become a major problem.

In addition, the polyester fiber usually contains 1 to 5% by weight of a polyester oligomer (hereinafter referred to as an oligomer) produced as a by-product during the manufacturing process. Here, the oligomer is mainly cyclic ethylene terephthalate. When dyeing polyester fibers, such oligomers elute from the inside of the polyester fibers onto the fiber surface. Furthermore, the oligomer elutes in the dyeing bath and reattaches to the polyester fiber surface upon cooling after dyeing. The adhesion of such oligomers causes various problems.

For example, when polyester fibers are dyed with cheese, the dyed polyester fibers cause problems such as whitening phenomenon in which oligomers accumulate in the inner layer due to the filter phenomenon, dull hue, and difference in hue between the inner and outer layers. In the post-process, process troubles such as deterioration of unresolvability in the weaving process, thread breakage, and accumulation of scum in the guide roll portion and the air nozzle portion are caused. Further, when the polyester fiber is a cloth, it causes problems such as shadow spots and non-staining. Such a problem also occurs in a polyester-based composite material in which a polyester-based fiber is composited with another fiber material (hereinafter, the polyester fiber and the polyester composite material are collectively referred to as a polyester-based fiber).

In addition, when dyeing polyester fibers, unfixed dyes, dyeing bath processing agents, dyeing aids, decomposition products thereof, etc. remain in the dyeing bath, or oil components and glues attached to the fibers. Components, oligomers, and other stain components (hereinafter collectively referred to as stain components) fall off and adhere to the inside of the dyeing machine, contaminating the dyeing machine equipment and the like. If these stain components are not completely removed, the stain components will adhere to the polyester fibers again during the dyeing operation, resulting in deterioration of the quality and work efficiency of the polyester fibers.

Therefore, in order to solve such a problem, the methods described in Patent Documents 1 to 3 have been proposed. The method described in Patent Document 1 is a method for solving a problem caused by refining. By using a pH slide agent and changing the dyeing solution to alkaline-acidic, it is refined in an alkaline state and is acidic. It is dyed in the state. However, in this method, it is difficult to adjust the amount of the pH slide agent added, and there is a concern that the free acid of the pH slide agent may combine with a divalent metal component such as calcium or magnesium to generate scale.

The method described in Patent Document 2 is a method for solving a problem caused by an oligomer, and is a polyester copolymer obtained by polycondensing a dibasic acid having a sulfonic acid base and a dihydric alcohol component containing polyethylene glycol. An oligomer remover containing a coalescence is disclosed.
The method described in Patent Document 3 is a method for solving a problem caused by stains on a can body, and discloses a can body cleaning agent composition containing a terpene hydrocarbon and / or a terpene alcohol and a specific nitrogen-containing compound. Has been done.
However, even if these methods are used, their respective performances are insufficient, and the current situation is that further measures are required.
