Description

[Detailed description of the invention] The present invention relates to a treatment agent for fibers.

More specifically, the present invention relates to a fiber treatment agent that improves the light resistance of fibers dyed with disperse dyes, particularly polyester fibers or acetate fibers.

In recent years, fibers dyed with disperse dyes have been widely used for car seats, tents, carpets, curtains, etc. In these fields, the color of dyed products changes due to prolonged exposure to sunlight, which poses a major problem in use.

Conventionally, attempts have been made to improve the above drawbacks by changing the structure of the disperse dye itself, but this is still insufficient and it is difficult to improve the light fastness of dyes of all hues. .

The present inventors have conducted intensive research to improve this problem, and as a result, have arrived at the present invention. That is, the present invention relates to the general formula: (wherein R, R' are hydrogen or an alkyl group of 01 to C5,
X is hydrogen or halogen) Compound (A)
, a sulfonate type anionic surfactant (B), and a polyoxyalkylene type nonionic surfactant (C).

The compound of general formula (1) is prepared as shown below, and then
Obtained by reduction.

In general formula (A), the C1 to C5 alkyl groups of R and R' include methyl group, ethyl group, n-propyl group, i
-propyl group, n-butyl group, and t-butyl group. Preferred are methyl group and t-butyl group. Examples of the halogen for X include C1°Br (chloro, brome), preferably CI. Examples of the compound of general formula (A) include the following.

As the sulfonate type anionic surfactant (B),
Examples include alkylbenzene sulfonate, alkylnaphthalene sulfonate, paraffin sulfonate, sulfosuccinic acid diester sulfonate, and the like. Preferred among these are alkylnaphthalene sulfonates, sulfosuccinic acid diester sulfonates, and mixtures thereof.

As the polyoxyalkylene type nonionic surfactant (C), higher alcohol alkylene oxide adducts,
Alkylphenol alkylene oxide adducts, fatty acid alkylene oxide adducts, polyhydric alcohol fatty acid ester alkylene oxide adducts, higher alkylamine alkylene oxide adducts, fatty acid amide alkylene oxide adducts, polypropylene glycol ethylene oxide adducts and their fatty acid esters, etc. Can be mentioned. Among these, preferred are higher alcohol alkylene oxide adducts, alkylphenol alkylene oxide adducts, polypropylene glycol ethylene oxide adducts, and fatty acid esters thereof, and particularly preferred are polypropylene glycol ethylene oxide adducts and fatty acid esters thereof. be.

The weight ratio of the compound of general formula (A) and (B) + (C) is usually 20:1 to 2:1, preferably 10:1 to 3.
It is 21. The compounding ratio of the compound of general formula (A> is 20:
If the number is more than 1, it becomes difficult to tear off the treatment agent, and the stability of the treatment bath deteriorates when the fibers are treated with the main treatment, resulting in uneven adhesion of compound (A) to the fibers i. on the other hand,
When the compounding ratio of the compound of general formula (A) is less than 2:1, it becomes difficult for the compound (A) to adhere to the fibers,
Furthermore, if the main color is treated with mauve at the same time, there will be adverse effects such as a decrease in the dye dyeing rate.

The treatment agent of the present invention is used in an aqueous dispersion system. To prepare a treatment agent suitable for use in an aqueous dispersion system, the usual method used when dispersing a solid with a high melting point such as compound (A) in water is used.

For example, first, a compound of general formula (A), (B) and (C)
The formulation is made by adding surfactants, water, and additives such as antifoaming agents and thickeners. In this case, the solids concentration in the formulation is between 20 and 60% by weight, preferably between 30 and 50% by weight. Next, the above-mentioned compound is prepared by grinding and dispersing it with a ball mill or a mycolloider (Tokushu Kakoki (+11gR), etc.).

The processing agent of the present invention is used in the form of a processing solution diluted with water. The solid content concentration of the processing agent in the processing liquid is usually 0.05 to 10% o, w, f (based on the weight of fiber)
, preferably 0.1 to 3% o, w, f.

When the content is less than 0.05% O, W, f, almost no light resistance improvement effect is observed. Also, 10% o, u, f,
Even if the amount is increased, no further effect of improving light resistance is observed, which is uneconomical.

Examples of methods for applying this treatment agent to fibers include a method in which the fibers are treated in advance before dyeing, a method in which the fibers are treated together with a dye during dyeing, and a method in which the fibers are treated after dyeing.

Of these, a method in which the fibers are treated together with a dye during dyeing is usually the most preferred. When the present treatment agent is used in a dyeing method using the dip dyeing method or the thermosol method, the present treatment agent is added to the dyeing bath. In addition, in the case of the textile printing method, the present processing agent is added to the color paste.

The dye used here is usually an azo or anthraquinone disperse dye.

The treatment conditions must be such that the structure of the amorphous region of the fiber to be treated is relaxed and the compound (A) in the treatment agent diffuses into it.

For example, in the case of polyester fibers, when treated by the dyeing method, it is usually 10 to 60 minutes at 100 to 130 °C, and when treated by the thermosol method, it is usually 30 to 12 minutes at 190 to 210 °C.
It is 0 seconds. When processing using the textile printing method, in the HT method (normal pressure high temperature steaming method), it is usually
IO minutes, liver (high pressure steaming method), 110-1
20-40 minutes at 30°C.

When applying this treatment agent to fibers, it can be used in combination with various chemicals depending on the method. For example, in the case of processing before dyeing, scouring agent, in the case of dyeing method, dye, leveling agent,
Antifoaming agents, etc., dyes and anti-migration agents in the case of the thermosol method, dyes, sizing agents, etc. in the case of the textile printing method, and various finishing agents etc. when used after dyeing.

Fibers to which the treatment agent of the present invention is applied include polyester synthetic fibers and acetate fibers. That is, they are polyester fibers such as polyethylene terephthalate, polyethylene terephthalate/isophthalate, polyethylene terephthalate/paraoxybenzoate, polyethylene terephthalate/butylene terephthalate, and acetate fibers such as diacetate and triacetate. Further examples include blends of the above-mentioned polyester fibers or acetate fibers with other natural fibers, regenerated fibers, semi-synthetic fibers, synthetic fibers, etc., interwoven fabrics, and the like. Examples of its form include cotton, thread, tow, top, skein, knitted fabric, and nonwoven fabric.

The fiber treatment agent of the present invention is uniformly dispersed in the treatment liquid, has excellent emulsion stability, and uniformly and stably diffuses and permeates into the fibers. Therefore, by using the treatment agent of the present invention for polyester fibers or acetate fibers, the light resistance of these fibers dyed with disperse dyes can be significantly improved.

The fiber treatment agent of the present invention will be explained in detail below with reference to Examples, but the present invention is not limited thereto.
