Description

Description: FIELD OF THE INVENTION The present invention relates to a fiber treatment agent, and more particularly, to preventing yellowing of fibers and suppressing rusting of wires and the like in a card machine in a spinning process. The present invention relates to a fiber treatment agent that can be used.

(Prior art) As oil agents for imparting a soft feeling and antistatic property to textile products, waxes, fatty acid esters, phosphate salts having a long-chain alkyl machine, quaternary ammonium salts, and the like are conventionally known. Is generally used. Oils containing aminoalkyl group-modified diorganopolysiloxane as the main component (JP-B-48-1480, JP-B-54-480)
No. 43617) is also used because a satisfactory smoothness and flexibility can be obtained for textile products.

(Problems to be Solved by the Invention) However, textiles treated with an alkoxysilane compound having a quaternary ammonium chloride-containing organic group may be heated or irradiated with sunlight, ultraviolet rays, or the like, or may be affected by an antioxidant over time. A serious disadvantage of yellowing.

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

Also, 2,6-di-t- used as an antioxidant
Butyl-4-methyl phenol and (BHT) and NO _x, in particular, yellowing due to promoted reactions alkaline conditions, a phenomenon that occurs on a textile treated with a weak alkaline oil also seen.

When spinning raw cotton treated with an oil agent containing a quaternary ammonium salt type surfactant which has been conventionally used, rust is generated on a wire of a card machine or the like due to the effect of the oil agent, which is extremely serious. Was a problem.

An object of the present invention is to provide a fiber treating agent capable of suppressing yellowing of the above-mentioned fiber product and rusting in a spinning process without impairing smoothness, flexibility and electrostatic property.

(Means for Solving the Problems) That is, the present invention relates to an alkylsulfonate alkali metal salt having 12 to 18 carbon atoms (A) and a compound obtained by adding 0 to 20 moles of an alkylene oxide to a higher alcohol having 12 to 18 carbon atoms. Phosphate alkali metal salt (B) and polyphosphoric acid (C)
And alkyl phosphate amine salts having 12 to 18 carbon atoms (D)
Wherein (A), (B), (C) and (D) are blended in a weight ratio satisfying the following conditions (a) and (b), respectively, and the PH is in the range of 4 to 5. It is a fiber treatment agent characterized in that there is.

(A) / (B) / (C) = 63-88 / 5-30 / 2-8 (a) {(A) + (B) + (C)} / (D) = 80-95 / 20- 5 (b) Examples of the alkali metal salt of alkylsulfonate (A) having 12 to 18 carbon atoms (A) (hereinafter sometimes simply referred to as component (A)) used in the present invention include, for example, sodium laurylsulfonate, myristylsulfonate and the like. It is possible to use at least one kind of sodium salt, cetylsulfonate sodium salt, stearylsulfonate sodium salt and the like, and particularly when the alkyl group has 14 to 16 carbon atoms.
Are preferred. If the number of carbon atoms in the alkyl group is out of the above range and is too large, the sizing property of the fiber becomes poor, and if the number is too small, the hygroscopicity becomes too large and the spinnability changes due to changes in temperature and humidity.

Next, a phosphate alkali metal salt (B) of a compound obtained by adding 0 to 20 moles of an alkylene oxide to a higher alcohol having 12 to 18 carbon atoms used in the present invention (hereinafter sometimes simply referred to as component (B)). ) Is, for example, 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, stearyl alcohol, and the like. -20 mol, preferably 0-50 mol.
If the number of added moles is too large, the antistatic property deteriorates,
Drops in the spinning process also increase.

Two or more alkylene oxides may be added. In this case, random addition or block addition may be used.

Particularly preferably used component (B) is sodium phosphate phosphate of a compound obtained by adding 2 to 4 moles of ethylene oxide to lauryl alcohol or acetyl alcohol.

The polyphosphoric acid (C) used in the present invention (hereinafter sometimes simply referred to as the component (C)) is used as the pH of the treating agent of the present invention.
Is adjusted to 4 to 5, and a mixture of mono, di, and triphosphoric acid is referred to as polyphosphoric acid. If the pH is out of the range of 4 to 5, any of the flexibility, yellowing prevention performance and rust suppression performance will be lost.

In particular, the fact that the generation of rust in the spinning process can be suppressed even though the pH of the treating agent is adjusted to a weakly acidic value of 4 to 5 is nothing other than completely.

Further, the treating agent of the present invention contains, as an essential component, an alkyl phosphate amine salt (D) having 12 to 18 carbon atoms (hereinafter sometimes simply referred to as component (D)). ), For example, at least one or more of lauryl phosphate amine salt, myristyl phosphate amine salt, cetyl sulfophosphate amine salt, stearyl phosphate amine salt and the like can be used.

In the present invention, the above components (A), (B) and (C) are (A) / (B) / (C) = 63-88 by weight ratio.
/ 5 to 30/2 to 8 is important. If the balance between (A) and (B) is out of the above range, sufficient flexibility and smoothness cannot be obtained, and (C) ) Is also out of the above range, it becomes difficult to adjust the desired PH.

Component (D) is {(A) + (B) + (C)} based on the total weight of components (A), (B) and (C).
/ (D) = 80-95 / 20-5, preferably 85-95 / 15-5, and it is necessary to mix them in a weight ratio. If the chipping is too large, on the contrary, the flexibility and the smoothness become poor, and the card is easily wound. In the present invention, the above components (A) to (D) are blended in a specific weight ratio and have good antistatic properties, smoothness, and flexibility, while preventing yellowing of fibers, and The unique effect of suppressing rusting of the card machine in the spinning process is exhibited.

The method of applying the treatment agent of the present invention to the fiber is not particularly limited, and a conventionally known method such as a spray method, a roller touch method, or an immersion method can be used. , Polyamide, polyacrylonitrile and the like.

The adhesion of the treating agent to the fibers is suitably 0.1 to 0.5% by weight. If the adhesion is too small, the flexibility, smoothness and antistatic properties are not sufficiently exhibited. The problem is that the treatment agent drops off in the process.

The fiber provided with the fiber treating agent of the present invention has excellent spinning process permeability, can be spun without damaging the carding machine, and is especially yellow in the finally obtained product. Since it is hard to change, it is extremely effective for white fiber products that do not require dyeing.

(Examples) Hereinafter, the present invention will be described specifically with reference to Examples, but the present invention is not limited thereto.

Examples 1 to 4 and Comparative Examples 1 to 5 Using a polyester raw cotton for carpet (no oil cotton), a treatment agent mixed in various compositions and weight ratios as shown in Table 1 was applied to the fiber in an amount of 0.3% by weight. And dried at 80 ° C. for 2 hours.
