Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an auxiliary agent for high-temperature dyeing of polyester synthetic fibers, and more particularly to an auxiliary agent for labid dyeing in a small bath ratio.

Conventionally, various ester-based nonionic surfactants or substances containing these and alkyl ether nalphate or aryl ether sulfate type anionic surfactants have been used as auxiliary agents for rabbit dyeing of polyester synthetic fibers. . Recently, from the viewpoint of further shortening the dyeing time, saving energy, and saving resources, the rapid dyeing method has become more popular than ever, with shorter heating times and dyeing using a small bath ratio. Along with this trend, there has been a phenomenon in which level dyeing cannot be obtained using conventional rabbit dyeing aids.

In general, measures such as increasing the amount of dyeing aid used have been taken in order to eliminate uneven dyeing caused by shortening the heating time and reducing the bath ratio, but this method can only solve the problem to a certain extent. Even if it is possible to do so, it is not possible to completely eliminate uneven dyeing, and the current situation is that the processing cost increases economically.

The inventors of the present invention have worked hard to solve the uneven dyeing caused by shortened heating times and small to medium bath ratios from the standpoint of dyeing aids, and as a result, they have developed a type of ether-type nonionic interface. It has been found that a dyeing aid containing an activator has an effective effect on eliminating these uneven dyeings.

That is, the present invention provides a compound represented by the following general formula (A) (
However, 几 is a higher alcohol residue having 6 to 18 carbon atoms or an alkylphenol residue having an alkyl group having 8 to 12 carbon atoms, and m is 2 to 12. This invention relates to a rabbit dyeing aid for polyester-based synthetic fibers, characterized in that it contains one or more of the following: n1io to 36 integers.

ζIn this regard, RK of the compound represented by the general formula (A) is described as natural alcohol having 6 to 1-8 carbon atoms, or synthetic alcohol, and furthermore, octylphenol, nonylphenol, dinonylphenol, totisylphenol. A compound represented by the general formula (A), which is an alkylphenol residue such as, and the alkyl chain thereof may be either chain or branched, and of course may be a residue of a secondary alcohol. Among them, Compound 8 particularly suitable for the purpose of the present invention is a higher alcohol having 7 to 9 carbon atoms, which is generally said to have good permeability.
is preferably a residue of octylphenol or nonylphenol. The compound of the present invention represented by the general formula A) can be easily obtained by a known method. That is, the above-mentioned higher alcohol or alkylphenol is treated with ethylene oxide (hereinafter abbreviated as BO), hood A and tetrapyrene oxide (hereinafter abbreviated as PO) in the presence of an acid or alkali catalyst under normal pressure or pressurized conditions. ) may be subjected to an addition reaction, and the method of addition may be any of BO alone, block addition of EO and PO, or dam/dam addition.

The number of moles of IiO or PO to be added is 2912 moles for EO and 0936 moles for PO. 2-10 mol, PO is 1 to 30 mol, and it is preferable that the number of added moles of PO does not exceed three times the number of added moles of EO, because if the number of added moles of PO increases beyond this, This is because it has a large adverse effect on dye dispersibility.

Additionally, if there is a concern about increased foaming due to the dyeing aid during dyeing 111, it is more suitable to add both HO and PO.

The compound of the present invention represented by the general formula (A) generally has poor solubility in water when used alone, or even if it is dissolved, a clouding point phenomenon occurs at high temperatures. Therefore, it is usually used in conjunction with an anionic surfactant. To solve the problem, a compound represented by the following general formula (B) ÷ CH, C 0 CH □ 80. M...
...(B) (However, π is an arylphenol having 2 to 6 benzene rings, or as or s having 1 to 12 carbon atoms.
, represents the residue of an alkylarylphenol having a group and 2 to 6 penzane rings, or a formaldehyde condensate thereof, and t is the weight of the residue represented by π,
Indicates an integer within the range of 150-350 weight-〇, and furthermore, M
is K, NJI, NH4, N-alkyl antheechum having 6 or less carbon atoms, or N-alkanol ammonium). It is preferable.

This means that the compound represented by the general formula (B) has the general formula (A)
This is because the compound of the present invention represented by can be sufficiently solubilized even at high temperatures, and at the same time, it itself has excellent dye dispersibility.

Regarding π in the compound represented by the general formula (B), it is phenol as detailed in Japanese Patent Publication No. 13792/1973.

Examples include arylphenol residues and alkylarylphenol residues such as phenylphenol, styrene or benzylation products of nonylphenols, or formaldehyde condensates thereof.

Regarding the method for synthesizing the compound represented by general formula (B).

Also, as is clear in Japanese Patent Publication No. 44-13792, the number of moles of EO to be added is 150-350 by weight relative to the weight of π, and below this, the present invention represented by the general formula (A) The dye dispersibility is poor when used in combination with the above compounds, and the level dyeing properties are poor when used in combination with this compound.

Compound of the present invention represented by general formula (A) and general formula (B)
The compounding ratio of the compound shown is (A): (B) -7
:3 to 2:8, but 6:4 to 4:6 is most preferable in terms of dye dispersibility and level dyeing.

Generally, the blends of compounds represented by the general formulas (B) and (B) have sufficient dye dispersibility and level dyeing properties, but the level dyeing properties of dye formulations with different dyeing properties, especially ibb is used when low foaming is required, in this case (A) and (B)
In the case of a compound represented by the following general formula (C) and a lyserine residue, where X is a residue represented by -, 150 to 350 weight - an integer within the range of 4- for residues denoted by Rt'OO-
8, and in the case of glycerin or diglycerin residues, an average of 4 to 8 integers per hydroxyl group). The characteristic dyeing aid is very effective.

B- in the compound represented by the general formula (C) is a common higher fatty acid residue having 6 to 18 carbon atoms, as detailed in Japanese Patent Publication No. 48-599 or No. 55-35506. The synthesis method is also as described in the above patent publication, and the limited range of the number of moles of EO to be added is such that if it is less than this, it will have an adverse effect on the dye dispersibility, and if it is more than this, the level dyeing property will be impaired. Furthermore, since it is difficult to achieve low foaming, the following proviso is prescribed.

The compounding ratio of the compounds represented by the general formulas (A), (B) and (C) is first (human): (C)-7: 3 to 3, and then K (human) and (C) The compounding ratio of the compound represented by (B) and the compound represented by (B) is 7:3 to 2.
: 84! The ratio is preferably 6:4 to 4:6.

In addition, dyeing aids containing the compound of the present invention represented by the general formula (B) and a surfactant other than the compound represented by the general formula (B) or (C) may be used for dyeing at an increased temperature increase rate, It cannot be expected to have as effective an effect as the present invention in terms of either level dyeing or dispersibility in small bath ratio dyeing.

Examples of the present invention are shown below, and there are some chestnuts used in the examples. However, the auxiliary agents used are a lower alcohol solvent and water, each of which is 30-30%.
