Abstract

PURPOSE:To provide the title agent for soaping, at low temperatures, cellulose fiber dyed products dyed with e.g., reactive dye, having the comparable effect to the case in the conventional high-temperature treatment with little white cloth staining, containing a water-soluble salt of polymerized fatty acid. CONSTITUTION:Firstly, a starting raw material for polymerized fatty acid, pref. an ethylenic unsaturated fatty acid (e.g., oleic acid, linoleic acid) is polymerized to prepare a soaping agent containing a water-soluble salt of polymerized fatty acid (e.g., alkali metal salt). Thence, using a soaping bath of pH10-12 containing said soaping agent, a dyed product of cellulose fiber such as cotton, linen or regenerated cellulose fiber dyed with reactive dye, naphthol dye or styrene dye is put to soaping treatment at temperatures as low as <=75 deg.C, thus obtaining a dyed product with little white cloth staining, clear and excellent in wet fastness, resulting in effects comparable to those in the conventional high-temperature (>=90 deg.C) soaping.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a soaping agent for dyed articles containing cellulose fibers and a method for treating dyed articles. For more details, use reactive dyes to dye textile products containing cellulose fibers! This invention relates to a soaping agent J'3 and a treatment method for removing undyed dyes after dyeing with dyes including non-dyes.

[Prior Art] Conventionally, cellulose fiber dyeing products use soaping agents such as ethylene oxide adducts of higher amines, sorter 1h of higher fatty acids, ethylene oxide 1 adducts of higher fatty acids, and sodium polyacrylate! ') Soap or wash with an aqueous solution of 0''C or higher.

[Problems to be solved by the invention] In recent years, the dyeing process of textile products has been forced to be streamlined to save energy and reduce costs, and for example, there has been a demand for soaping or washing at a low temperature of 70 to 75 degrees Celsius. However, the conventional soaping agents described above have a comparable soaping effect when used at 90°C.

[Means to Solve the Problem] The present inventors have carried out soaping or washing at a low temperature of 70 to 75°C, which is the same as when soaping or washing is carried out at a temperature of 90°C or higher, for the above-mentioned dyed products containing cellulose fibers. As a result of extensive research to find an effective soaping agent and treatment method, the present invention was achieved.

That is, the present invention uses a soaping agent for dyed cellulose WC fibers characterized by containing a water-soluble salt of a polymerized fatty acid, and a soaping agent containing at least one water-soluble salt of a polymerized fatty acid to adjust the pH of a soaping bath. A method for treating dyed cellulosic fibers, which comprises soaping the dyed cellulosic fibers at an IO of less than 12.

Examples of the polymerized fatty acid in the present invention include polymerized fatty acids obtained by polymerizing fatty acids.

Fatty acids include natural or synthetic saturated fatty acids, ethylenically unsaturated fatty acids, and acetylenically unsaturated fatty acids having 8 to 24 carbon atoms.

Saturated fatty acids, ethylenically unsaturated fatty acids and acetylenically unsaturated fatty acids can generally be polymerized in somewhat different ways.

It is difficult to polymerize saturated fatty acids, but polymerization is possible with di-t-peroxide.
This can be done at high temperatures using peroxide catalysts such as butyl. Yields of heavy metal products are generally low.

Suitable saturated fatty acids are straight or branched, such as cafprilic acid, belarconic acid, capric acid, lauric acid, myristic acid, valmitic acid, isopalmitic acid, suderic acid, aragic acid, behenic acid. and gutuceric acid.

Ethylenically unsaturated fatty acids can be easily polymerized by catalytic or non-catalytic polymerization methods. Non-catalytic polymerization generally requires high temperatures of around 3'3°C. Catalysts suitable for polymerization include acidic or alkaline clays, peroxide 1. Examples include butyl, boron trifluoride, Lewis acids, anthraquinone, sulfur dioxide, and the like.

Suitable ethylenically unsaturated fatty acids include: ゛(-octic acid, myristoleic acid, tuzuic acid, palmic acid, petroselic acid, oleic acid, elaidic acid, vaccenic acid, phosphoric acid, Cetoleic acid, nervonic acid, linoleic acid, lylic acid, eleostearic acid, hiragic acid, moloctic acid, /l, )1.12゜15,18-eicosapentaenoic acid, eicosapentaenoic acid, nisic acid, Hiragashira Branched or straight chain poly and monoethylenically unsaturated fatty acids such as acids and Shoalmoon acids.

Acetylenically unsaturated fatty acids can be polymerized simply by heating. Polymerization of these highly reactive substances can be carried out without catalysts.

Acetylenically unsaturated fatty acids are extremely rare in nature and are therefore expensive. Acetylenically unsaturated fatty acids include linear and branched monounsaturated and polyunsaturated acetylenically unsaturated fatty acids, specific examples of which are 1o-undecylenic acid, tauric acid, stearolic acid, behenolic acid and There is isamic acid.

Among these fatty acids, ethylenically unsaturated fatty acids are preferred because they are easy to handle and relatively easy to polymerize, and oleic acid and linoleic acid are suitable starting materials for producing polymerized fatty acids.

Once the polymerized fatty acids or their derivatives, such as esters, as described above have been hydrogenated, they can be fractionated by conventional methods such as distillation or solvent extraction. It can also be used to reduce unsaturation and hydrogenate (before; 1:1 or after).

The typical composition of commercially available polymerized fatty acids based on C-18 unsaturated fatty acids is: 0-15% by weight C-18-basic acid (monomer) 60-80% C-36 dibasic acid (dimer) C-54 (and above) polybasic acid (trimer) 0-35% C-54.

Specific products include Verzadime 21G [monomer acid 8%

3%, 65%, and Henkel Hakusui Co., Ltd.

Examples of the water solubility of the polymerized fatty acids in the present invention include alkali metal salts <-t-r-lium, kaliuno-1, lithium salts, etc.), ammonium salts, and amine salts (methylamine, dimethylamine, triethylamine, monoethanolamine, tanolamine, I-liethanolamine salt, etc.). Among these, preferred are alkali metal salts, and particularly preferred are sodium and potassium salts.

The salt may be either a partial salt or a complete salt, but a complete salt is preferred.

This salt can be easily obtained by partially or completely neutralizing the polymerized fatty acid with a basic compound.

Basic compounds include alkali metal hydroxides such as thorium hydroxide, potassium hydroxide, and lithium hydroxide; amines such as methylamine, dimethylamine, triethylamine, monoethanolamine, jetanolamine, and triethanolamine; Examples include alkali metal carbonates such as sodium carbonate, potassium carbonate, and lityrim carbonate.

Among the water-soluble salts of polymerized fatty acids, preferred are storium salt of dimer acid, potassium salt of dimer acid, storium trimer acid salt, potassium salt of trimer acid, storium salt J5 of dimer acid and trimer acid mixture, and storium salt of dimer acid and trimer acid mixture. The power of the trimer acid mixture is ``h''.

Examples of fibers other than cellulose fibers to which the soaping agent of the present invention can be applied include natural fibers such as cotton and linen, and recycled fibers such as viscose rayon and copper ammonia rayon.

It may also be a blended or interwoven fabric of the above fibers and other natural fibers (for example, wool, silk) or synthetic N fibers (for example, polyester/cotton blend, 11 clearamide fiber, polyacrylic fiber, acetate fiber). Examples of fibrous forms include cotton,
Thongs, tape, cheese, cake, cloth, threads, etc. are all fine.

these! When dyeing navy blue products, if only cellulose fibers are used, dyes such as reactive dyes, naphthol dyes, sulfur dyes, and thren dyes can be used. On the other hand, dyes such as acid dyes, metal-containing complex salt dyes, reactive dyes, disperse dyes, and cationic dyes can be used to dye the fibers of blended and interwoven fabrics containing fibers other than cellulose fibers.

When dyeing textile products using these dyes 1, the dyeing methods are one-bath one-stage method (single fiber), two-bath two-stage method (polyester/cotton blend), and two-bath two-stage method (-one bath one-stage method). Examples include blended fabrics, interwoven fabrics, etc. that are difficult to produce using the one-bath or two-step process.

These dyeings can be carried out in a conventional manner using a cheese dyeing machine, a drum dyeing machine, a wince dyeing machine, or a jet dyeing machine.

The thus dyed product is subjected to soaping. When soaping or washing, the soaping agent of the present invention may be used, if necessary, with other compounding agents, such as other soaping agents (ethylene oxide adducts of argylphenol, ethylene oxide adducts of higher alcohols, ethylene oxide adducts of higher fatty acids, etc.). Amidated products of higher fatty acids and alkanolamines, ethylene oxide adducts of higher amines, alkali metal salts of higher fatty acids, sulfuric ester salts of higher alcohols, formalin condensates of sodium naphthalene sulfonate, sodium polyacrylate, polyvinylpyrrolidone, methyl carboxymethyl cellulose, etc.) and alkanolders (caustic soda, soda carbonate, sodium tripolyphosphate, etc.). Of all the soaping agents, the amount of soaping agents used is usually less than 50 times. These are an aqueous solution (J: aqueous dispersion) and a soaping bath or a washing bath.

Soaping agent (A) of the present invention and other soaping agents (B)
When used together, there are no restrictions on how they can be used together.

For example, (A) and (II) may be mixed in advance to prepare a soaping agent solution consisting of (A) and (B) in a bath (water bath). Another method is to dissolve (A), (1), and (II) in the liquid or water and add both simultaneously or sequentially to the bath.

The soaping agent of the present invention may also be prepared by adding polymerized fatty acids and/or other soaping agents to a basic compound bath, or vice versa.

It is also possible to treat the raw material first in a bath of a basic compound and then in a bath of polymerized fatty acids and other soaping agents prepared in a separate bath.

The concentration of total soaping agent in the bath is usually 0.2 to 7 g/
l, preferably 0.4 to 52. /l (solid content).

When alkaline bilgu is used, its concentration is usually 0 to 10 g/l, preferably 0 to 5 g/l.

1]1 (of the soaping bath is usually from 10 to less than 12, preferably from 10.5 to 11.8. pl+ is 1
In the case of 1), the effect of shedding and removing undyed dyes on the fibers becomes poor. Moreover, if it exceeds 12, the dyed product will be greatly discolored and the reproducibility of the hue will be lacking.

The soaping of the present invention is usually carried out at a temperature of 70 to 75 degrees Celsius, but of course it may also be carried out at a temperature of 1] 0 degrees Celsius or higher, which is naturally more effective than the conventional soaping method (soaping agent). Needless to say, it is excellent.

Is the soaping agent of the present invention a liquid? It can also be used for soaping dyed products dyed with R dyeing machines, Wince and other dyeing machines, but for example, it can be used to take out dyed products dyed with jet dyeing machines out of the dyeing machine. It is preferable to soap continuously.

When soaping using a jet dyeing machine, does it usually include dyeing after dyeing? (Excluding '2, washing with water, forming the soaping bath of the present invention in the dyeing machine, operating the dyeing machine for soaping or washing). The conditions in this case are usually as follows.

That is, the cloth speed (n+/min) is 60 to 150, and the dyeing rotation number (
times/min) 1.5-3, bath ratio 1:10-20, heating time (min) 15-25, temperature ('C) 20-75℃ (actual soaping temperature 70-75℃) The total soaping time (minutes) is 25-50 minutes. After soaping, the dyed product is washed with water and dried.
