Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a scouring agent composition,
More particularly, textile products, especially wool or wool-containing knitting or weaving oils, knitting or weaving oils and waxes, and cotton or knitting fabrics containing knitting oils and waxes. The present invention relates to a scouring agent composition used in scouring for removing slag.

[0002]

2. Description of the Related Art Conventionally, scouring of wool or woven or knitted fabric containing wool is carried out by solvent scouring using a chlorine-based solvent such as trichloroethane, or polyoxyethylene alkylphenyl ether or higher alcohol sulfate ester salt is used as a scouring agent, respectively. It was common to carry out alone or in combination in an aqueous system. For wool-dyed woven and knitted fabrics, a method of scouring using a chemical agent containing polyoxyethylene alkylphenyl ether or higher alcohol sulfate ester salt and peroxide and polyhydric alcohol has been proposed (for example, Kaihei 1-192870 publication). Further, conventionally, scouring of cotton or knitted fabric containing cotton is generally scouring using a scouring agent mainly composed of a nonionic activator such as polyoxyethylene alkylphenyl ether or polyoxyethylene alkyl ether as a scouring agent. there were.

[0003]

However, the conventional water-based scouring agents for wool are not sufficient in the effect of emulsifying and removing the adhered oil, or the oil or wax once emulsified and dispersed is demulsified during scouring. However, there is a defect that oil spots occur due to re-adhesion to the cloth and separation, and trouble occurs in the next dyeing step. In addition, for cotton or knitted fabrics containing cotton, the smoothness of the knitting oil is emphasized in recent years in order to respond to the increase in the speed of knitting machines, and high-speed knitting oil with good smoothness but difficult to remove is used. Therefore, the conventional scouring with the scouring agent has the same problem as in the case of wool.

[0004]

[Means for Solving the Problems] The present inventors have found that troubles such as dyeing spots and oil spots in the dyeing process are problems in the scouring, which is the previous process, and in particular, the oil once emulsified and dispersed and dropped from the dough is being scoured. From the viewpoint of causing emulsion destruction, separation, and reattachment, as a result of diligent studies to obtain a refining agent having excellent anti-redeposition properties, a compound (3 kinds) having a specific surface-active action was identified. It has been found that the redeposition of oil can be prevented and troubles in the dyeing process can be prevented by refining using a refining agent composition containing a specific ratio.

That is, the present invention provides the following (a) and (b)
And (c) compound, wherein the solid content weight ratio of each of the compounds (a), (b) and (c) is 30 to 80% by weight based on the total solid content weight, (b). Is 5 to 30% by weight and (c) is 10 to 50% by weight, which is a scouring agent composition. (A): General formula (1) RO (AO) nH (1) (In the formula, R is an alkyl group having 8 to 24 carbon atoms, an alkenyl group or an alkylaryl group, and A is 2 to 4 carbon atoms.
And an n is an integer of 4 to 20.

When the carbon number is less than 8 or more than 24, the oil has poor emulsification and dispersibility and anti-redeposition property.

N is 4 to 20, preferably 5 to 16. When n is less than 4 or more than 20, the emulsification dispersibility of oil and the anti-redeposition property become poor.

Examples of the alkylene group of A include alkylene groups having 2 to 4 carbon atoms such as ethylene group, propylene group and butylene group. When the compound of the general formula (1) contains two or more of them, they may be contained in any of a block form and a random form.

The polyoxyalkylene chain represented by (AO) n contains 80% by weight or more of oxyethylene units. If the polyoxyethylene unit content is less than 80% by weight, the emulsifying dispersibility of oil and the anti-redeposition property will be poor.

EFFECTS OF THE INVENTION In recent years, the speed of knitting machines has increased due to rationalization, and high-speed knitting oil with excellent lubricity has come to be used. However, high-speed knitting oil is refined and removed from conventional oils. It is difficult to do so, and it is often the case that redeposition occurs during scouring and troubles occur in the dyeing process. Furthermore, the bath ratio has become smaller due to the rationalization of the refining process, and problems are more likely to occur. The refining agent composition of the present invention, when used as a refining agent in refining in an aqueous system to remove the knitting oil, weaving oil, etc. adhering to the fibers, the oil is emulsified and dispersed to remove from the fibers. In addition to being excellent in effect, it has the effect of stably emulsifying and dispersing the oil in a wide temperature range, so that the oil once emulsified and dispersed during refining may cause emulsion destruction and reattach to the fiber. In addition, it has the effect of preventing the occurrence of troubles such as stains and oil stains in the dyeing step after scouring, and is very useful as a scouring agent.
