[0002]

2. Description of the Related Art Conventionally, as a scouring agent composition, a polyoxyethylene alkylphenyl ether, a polyoxyethylene alkyl ether, or a higher alcohol sulfate ester salt is generally used alone or in combination in an aqueous system. A method has also been proposed in which polyester fibers are scoured using a non-ionic surfactant obtained by adding ethylene oxide to a higher alcohol and further blocking propylene oxide. (Japanese Patent Publication No. 63-12192) Further, wool yarn-dyed fabrics and knitted fabrics are scoured using a chemical containing a polyoxyethylene alkyl phenyl ether, a higher alcohol sulfate, a peroxide and a polyhydric alcohol. Methods have also been proposed.

[0003]

However, the conventional scouring agent has a high viscosity at a high concentration or at a low temperature and is difficult to handle. In addition, troubles due to foaming, such as poor scouring due to foaming during scouring, have occurred. In addition, the removal properties of knitting or weaving oils and waxes are insufficient, and the removed oils and waxes have insufficient emulsifying properties, and the oils and waxes once removed adhere to the fabric again, causing oil spots. And the drawback that trouble occurs in the dyeing process.

[0004]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems. As a result, when the concentration is high or at a low temperature, the viscosity is low, the foaming during scouring is low,
The present inventors have studied a scouring agent composition which is excellent in removing oil and wax, and which has good emulsifiability of removed oil and wax and can prevent dyeing trouble.

That is, the present invention comprises a nonionic surfactant (A) and an anionic surfactant (B) represented by the following general formula (1), and the solid content weight ratio of each of (A) and (B) is as follows: (A) is 50 to 95% by weight, and (B) is 5 to 50% by weight, based on the total solid content weight. Formula _{R-O - [(C 2} H 4 O) n / C 3 H 6 O) m] - (C 2 H 4 O) k- (C 3 H 6 O) lH (1) { wherein, R Represents an aliphatic hydrocarbon group having 8 to 18 carbon atoms, n is an integer of 1 to 8, m is an integer of 1 to 5, k is 2-1.
An integer of 5 and l represent an integer of 1 to 5. [(C ₂ H ₄ O) n
/ C ₃ H ₆ O) m] indicates random addition.非 The nonionic surfactant (A) represented by the general formula (1) is usually produced by adding ethylene oxide and propylene oxide to a higher alcohol by a specific addition method.

The number of moles of the terminal propylene oxide block added is 1 to 5 mol, preferably 1 to 3 mol. If the number of moles of the terminal propylene oxide added is less than 1 mol, the foaming property becomes high and the
