Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a fiber treatment agent, particularly for preventing yellowing of fibers and also suppressing rusting of wires, etc. in carding machines in the spinning process. The present invention relates to a fiber treatment agent that can be used to treat fibers.

(Prior Art) Conventionally known oil agents for imparting soft texture and antistatic properties to textile products include waxes, fatty acid esters, phosphate salts having long-chain alkyl groups, and quaternary ammonium salts. is commonly used. In addition, oil agents containing aminoalkyl group-modified diorganopolysiloxane as a main component (Japanese Patent Publication No. 1480/1980, Japanese Patent Publication No. 43617/1983) can also provide textile products with satisfactory smoothness and flexibility. It has been used since.

(Problem to be Solved by the Invention) However, textile products treated with an alkoxysilane compound having an organic group converted to quaternary ammonium salt deteriorate over time due to heating, irradiation with sunlight or ultraviolet rays, or the influence of antioxidants. It had a serious drawback of yellowing.

Furthermore, even in textile products treated with oils containing aminoalkyl group-modified diorganopolysiloxane as a main component, yellowing occurs due to oxidation of the aminoalkyl groups during the heat drying process or during storage after heat drying. Can be seen.

In addition, 2,6-di-t-, which is used as an antioxidant,
Yellowing due to the reaction between butyl-4-methylphenol (BHT) and NO, which is particularly accelerated under alkaline conditions, has also been observed on textile products treated with weakly alkaline oils.

When raw cotton is treated with an oil agent containing a quaternary ammonium salt type surfactant, which has been used in the past, rust may occur on card machine wires, etc. due to the influence of the oil agent. A serious problem had arisen.

An object of the present invention is to provide a fiber treatment agent that can suppress yellowing of textile products as described above and rusting during the spinning process without impairing smoothness, flexibility, and antistatic properties.

(Means for Solving the Problem) That is, the present invention provides a compound in which 0 to 20 moles of alkylene oxide is added to an alkyl sulfonate alkali metal salt (A) having 12 to 18 carbon atoms and a higher alcohol having 12 to 18 carbon atoms. It consists of an alkali metal phosphate salt (B), a polyphosphoric acid (C), and an alkyl phosphate amine salt having 12 to 18 carbon atoms (D), and (^), (B), (C) and (D) are each represented by the following ( This fiber treatment agent is characterized in that it is blended in a weight ratio that satisfies the conditions (a) and (b), and has a pH in the range of 4 to 5.

(A}/(B}/CC)=63~8815~3
0/2~8 (A) ((A) + (B) +
(C)}/ (D) = 80~95/20~5 (
0 Examples of the alkyl sulfonate alkali metal salt (A) having 12 to 18 carbon atoms (hereinafter sometimes simply referred to as component (A)) used in the present invention include lauryl sulfonate sodium salt, myristyl sulfonate sodium salt, Cetyl sulfonate.

It is possible to use at least one or more kinds of salts such as sodium salts and stearyl sulfonate sodium salts, and those having an alkyl group having 14 to 16 carbon atoms are particularly preferred. If the number of carbon atoms in the alkyl group is out of the above range, if it is too large, the fiber cohesiveness will be poor, and if it is too small, the hygroscopicity will become too large, resulting in large fluctuations in spinnability due to changes in temperature and humidity, which is not preferable.

Next, a phosphate alkali metal salt (B) of a compound obtained by adding 0 to 20 moles of alkylene oxide to a higher alcohol having 12 to 18 carbon atoms (hereinafter sometimes simply referred to as component (B)) used in the present invention. For example, it is a phosphate alkali metal salt obtained by adding an alkylene oxide having 2 to 3 carbon atoms to a higher alcohol such as lauryl alcohol, myristyl alcohol, cetyl alcohol, or stearyl alcohol, and the number of moles of alkylene oxide added is 0 to 20. mol, preferably 0 to 5 mol.

If the number of moles added is too large, the antistatic property will deteriorate;
There will also be more shedding during the spinning process.

Further, two or more types of alkylene oxides may be added, and in that case, either random addition or block addition may be used.

Particularly preferably used component (B) is lauryl alcohol or acetyl alcohol containing 2 to 2 ethylene oxides.
This is the phosphate sodium salt of the compound with 4 moles added.

Polyphosphoric acid (C) used in the present invention (hereinafter simply referred to as component (
C). ) is the PH of the treatment agent of the present invention.
Polyphosphoric acid is a mixture of mono-, di-, and triphosphoric acids. If the pH is outside the range of 4 to 5, flexibility
Either the anti-yellowing performance or the anti-rust performance will be lost.

In particular, it is completely surprising that the occurrence of mackerel during the spinning process can be suppressed even though the pH of the processing agent is adjusted to a weakly acidic level of 4 to 5.

Furthermore, in the treatment agent of the present invention, an alkyl phosphate amine salt (D) having 12 to 18 carbon atoms (hereinafter simply referred to as component (
D). ) as an essential component, and as the component (D), at least one of lauryl phosphate amine salts, myristyl phosphate amine salts, cetyl phosphate amine salts, stearyl phosphate amine salts, etc. can be used. .

In the present invention, the above components (A), (B) and (C)
However, the weight ratio is (A}/ (B}/ (C) = 63
It is important that the balance between (A) and (B) be adjusted within the range of ~88/5~30/2~8, and if the balance between (A) and (B) is outside the above range, sufficient flexibility and smoothness will not be obtained. If (C) is also out of the above range, desired pH adjustment will be difficult.

In addition, component (D) includes the above-mentioned components (A), (B) and (
For the total weight of C) ((A) + (B) + (C)}
/ CD>=80-95/20-5, preferably 8
It is necessary that the weight ratio of component (D) is 5-95/15-5, and if the ratio of component (D) is too small, the antistatic properties will be lacking. If there is too much, not only will the flexibility and smoothness be poor, but the card will also tend to get stuck. In the present invention, only when the above-mentioned components (A) to (D) are blended in a specific weight ratio, it is possible to prevent yellowing of the fibers while having good antistatic properties, properties, smoothness, and flexibility. , it has the unique effect of suppressing the rusting of the carding machine during the spinning process.

The method of applying the treatment agent of the present invention to the fibers is not particularly limited. Conventionally known methods such as spray method, roller touch method, dipping method, etc. can be used, and the fibers to be treated are also not limited, e.g. It is highly possible to apply it to synthetic fibers such as polyester, polyamide, and polyacrylonitrile.

The adhesion rate of the treatment agent to the fibers is 0.1 to 0.
5% by weight is appropriate; if the adhesion rate is too low, flexibility and
Smoothness and antistatic properties are not sufficiently expressed, and on the other hand, if the amount is too high, the treatment agent may fall off during the spinning process.

The fibers to which the fiber treatment agent of the present invention has been applied have excellent permeability in the spinning process, and can be spun without damaging the carding machine, and the final product is particularly yellow. Since it is difficult to change, it is extremely effective for white textile products that do not require dyeing.

(Examples) Hereinafter, the present invention will be specifically explained with reference to Examples, but the present invention is not limited to these in any way.
