Description

[Detailed description of the invention] The present invention relates to a composition for dyeing textile materials.

More particularly, the present invention relates to dye compositions containing N-acetylethanolamine to facilitate the dyeing of textiles.

Various dyes have been used to impart desired colors to textile materials, including textiles.

Such fiber materials include "natural" fibers such as cellulose-based fibers such as noodles, keratin-based fibers such as wool,
and silky fibroin-based fibers, and “man-made”
Fibers such as derivatives of natural fibers such as rayon;
"Synthetic" fibers such as nylon, polyester and polyolefin fibers of non-natural origin are included.

A variety of dyes are useful for these various fibers, including acidic, basic, direct, sulfurized, vat, leucoester, azo, acetate, pigment, oxidative, natural and inorganic dyes.

In addition to the textile industry, dyes are also used in the hair beauty industry for hair dyeing.

Therefore, in this hair beauty field, there is a need to eliminate toxicity or other negative effects on the skin or hair of the person receiving the hair dye treatment.

Known dyes have drawbacks in the resistance of the dyed textile material to fading, resistance to color erosion due to friction etc., and the depth of color imparted to the textile material upon dyeing.
Additionally/or, there are difficulties in the efficiency and ease with which the dye is applied to the garment to be dyed.

Thus, numerous efforts have been made to improve the dyeing of textile materials.

However, known means of improving and facilitating such staining methods have met with only incidental and/or limited success.

Such measures are often costly and only alleviate the above-mentioned disadvantages to a certain extent and/or have been found to be useful only when certain types of dyes are used.

According to the invention, the incorporation of N-acetylethanolamine into dyeing compositions provides a more durable coloration than previously obtained, accelerates the dyeing and/or increases the dyeing composition. It has now been discovered that dyeings can be obtained with colors exhibiting a certain resistance.

The present invention has been found to be useful across all types of dyes in the art.

Of particular importance is that the invention is broadly applicable to various types of fiber materials.

Thus, the invention can be used to dye knitted materials such as noodles, wool, silk, rayon, acetate, nylon and other natural or man-made fiber materials, and also to treat human hair.

In the hair beauty industry, N-acetylethanolamine is
Recognized as a highly effective conditioner or care aid for hair, it can be used instead of mineral oil derivatives in shampoos, rinses, conditioners, etc. to coat the hair, flatten it to prevent fly-ups, and add shine. It is used to give a unique appearance.

However, it has not been previously recognized that N-acetylethanolamine also has the function of promoting hair dyeing in addition to the above-mentioned functions.

Furthermore, it was not recognized that this effect occurs not only on hair but also on other fiber materials, and that this effect occurs not only with conventional dyeing compositions but also with other dyes.

In addition to its newly discovered properties, namely its function as a dye accelerator, N-acetylethanolamine retains the benefits generally recognized in the hair care industry.

Due to the presence of the amine in the dyeing composition, its known hair care or conditioning function is therefore retained here as well.

Therefore, in addition to exhibiting high coloring, the present dyeing composition does not damage the garments to be dyed as much as before.

Without wishing to be bound by any theory, it is believed that at least one means by which N-acetylethanolamine functions to promote dyeing is the ability of the amine to swell the fibers when present in the treated material. It will be done.

Such swelling of the individual fibers of the dyed object may account for the enhanced or accelerated penetration of the dye into the dyed object.

It also improves the observed facilitation and ease of staining and (
or) can explain the fading resistance or color fastness loss of the dyed product.

As stated above, the chemical composition and mechanism of the dyes used in the compositions are not critical.

Well-known systems of conventional methods, such as oxidation dyes, basic dyes, and heavy metal salt/reducible sulfur-containing compound systems as shown later, such as bismuth citrate/precipitated sulfur (hereinafter referred to as The term reducible sulfur-containing compound is intended to mean precipitated sulfur as well as compounds such as sodium thiosulfate).

The conventional dye systems mentioned above usually constitute up to about 50% of the total weight of the dyeing composition, preferably from about 1 to 25%.

However, the exact proportions will vary in the usual manner depending on the dye and the intended use.

Thus, the proportion is not critical to the function of N-acetylethanolamine.

As in conventional methods (also in the compositions of the invention), the dye is provided in a liquid dispersion vehicle therefor, usually water or an aqueous mixture.

However, this is not essential.

This is because non-aqueous systems containing alcohols, mineral oils, etc. can be used.

Similarly, mixtures of aqueous emulsions and water-immiscible liquid emulsions are also suitable vehicles for the dye compositions of the present compositions.

N-acetylethanolamine may be used in almost any amount, but it usually constitutes about 1 to 25%, preferably 10 to 15%, of the total weight of the dye composition.

Although these proportions generally provide maximum dye enhancement, greater than the above proportions may be used for the purpose of imparting further conditioning to the treated textile material or when the N-acetylethanolamine constitutes a major part or all of the vehicle itself. can do.

Therefore, any N-
The amount of acetylethanolamine can vary widely.

Although the present invention has been described above using a preforming composition mainly applied to objects to be dyed, the present invention is not limited thereto.

The composition can also be formed on the textile material itself by sequential application of N-acetylethanolamine and dye.

Thus, in order to achieve the above-mentioned benefits, all that is required is the simultaneous presence of all the essential components of the dyeing composition V on the textile material or fabric to be dyed. show.

However, these examples are for illustrative purposes only;
It will be understood that there is no limitation on the scope of the invention.

Example ■ In a comparative dye test on the effectiveness of N-acetylethanolamine, two standard dyes FD&C Blue 4P1 (0,2
5% by weight) and D&C Yellow+10 (0.75% by weight) were used.

That is, 10% by weight of each of these two dyeing compositions.
Comparisons were made using two paired samples: a sample containing N-acetylethanolamine and a control sample not containing N-acetylethanolamine.

Various fabric swatches were mixed with the above four types of dyeing composition test samples (6
0° C.) for 1 minute.

After drying, the fabric swatches were visually compared for dye color intensity.

As a result, in some cases (in textile materials not normally dyed with the particular dye compositions mentioned above) dyeing is surprisingly accomplished with N-acetylethanolamine, and in other cases it is better than each control sample. It was found that staining was clearly promoted.

Fabrics that have demonstrated increased color strength due to the presence of N-acetylethanolamine include wool and worsted wool, rayon (trade name AVRIL), viscose rayon, silk, nylon, noodles, acetate, acrylonitrile (ACRILAN). ), triacetate (A
RNEL), acrylic (CRESLAN, 0RLON and ZEFRAN), polyester (DACRON, F
ORTREL and KODEL), olefins (HER
CULON) and modacrylic (VEREL and DY
across a wide range of fibers, including NEL) fibers.

Visual inspection shows that fabric swatches dyed in the presence of N-acetylethanolamine have less uneven color and less run and streaking than those dyed in its absence. It was difficult to come.

Thus, N-acetylethanolamine improved dye fixation on fabrics.

Example ■ A hair dye composition was prepared having the following formulation: Bismuth citrate 0.50% Triethanolamine 3.00% Alcohol
10.00% precipitated sulfur
0.50% octoxynol-90°10% (TRITON X-100) N-acetylethanolamine 15.00% water
70.80% fragrance
0.10% The composition was formed in a conventional manner.

However, N-acetylethanolamine (trade name: ACETAMIDEMEA) was added after the other components were combined.

To test this composition, bleached hair samples were dipped into the composition, removed, shaken to remove excess composition, and allowed to dry overnight at room temperature.

After drying, it was observed that the initially bronze hair was stained brown.

After repeated daily treatments for a week, the color became deeper and more durable.

Example ■ A hair dye composition was prepared having the following formulation: Paraphenylenediamine sulfur 5.00% Ethoresorcinol 1.00% Alcohol 15.00% N-acetylethanolamine 10.00% Oleic acid
0.40% ammonia (25% solution)
io, oo% water
63.60% This composition was prepared in a conventional manner and used with a peroxide developer.

When tested on bleached hair samples, the composition dyed the samples dark black.

Example ■ A semi-permanent shampoo set hair dye was prepared with the following composition: Monoethanolamine Lauryl 20.00% Sulfate Ethylene Glycol Monoste 7 3.00% Rate p-nitro-〇-phenylenedi 1.50% Amine diethanolamine coconut oil fat 3.00% acid N-acetylethanolamine 7.00% water
65.50% When used in hair shampooing, improved hair dyeing with high resistance to abrasive color erosion was observed.
