Abstract
The present invention relates to a cationizing agent for fiber dyeing capable of reducing the amount of neutral salt used when dyeing fibers with reactive dyes or direct dyes, and a fiber dyeing method using the cationizing agent. When the fiber is dyed using the polymeric cationizing agent according to the present invention, the amount of neutral salt such as sodium sulfate used can be reduced by 50% or more compared to the conventional fiber dyeing method, and thus the environmental problem due to excessive use of neutral salt can be directly improved.
Description
Technical Field
The present invention relates to a novel cationizing agent for fiber dyeing capable of reducing the amount of neutral salt used in fiber dyeing with a reactive dye or a direct dye, and a fiber dyeing method using the same.
Background
In fibre dyeing processes with reactive dyes and direct dyes, use is made of dyes such as sodium chloride (NaCl) or sodium sulphate (Na)2SO4) A neutral salt electrolyte. Using neutral saltsThe root cause of the electrolyte is as follows. First, the surface of cellulose-based fibers such as cotton has anionic properties, and thus a neutral salt is used in order to function as a neutralizing agent. Academic to improve substantivity (substantivity), reactive dyes or direct dyes are anionic, so that they can only approach cotton fibers if the neutral salts neutralize the surface charge of the cotton fibers. Secondly, when an excess of neutral salt is present in the dye bath (dyeingbath), the cations become more, inhibiting the dissociation of the dye and thus making the affinity with the fibre greater. Thirdly, reactive dyes that finish dyeing by a displacement reaction with the fiber play a catalytic role because the transition state of these chemical reactions is stabilized by neutral salts.
For the reasons mentioned above, in dyeing processes with reactive dyes and direct dyes, an excess of neutral salt (480 to 540 kg (bath ratio 1:6)) is required (over a minimum of 90g/L, for example 1,000 kg of cotton fiber dyed). The neutral salt has a maximum effect of neutralizing the surface charge of the fiber, thereby enabling the dye to approach the cotton fiber, but becomes hard when the neutral salt such as sodium sulfate is highly hygroscopic and adsorbs moisture in the air, thereby clogging the piping of the dyeing machine, thereby greatly reducing the production efficiency. Further, since neutral salts are the root cause of lowering of fiber fastness, a considerable amount of water is used for removing the neutral salts, and further, it is impossible to avoid the disturbance of the ecosystem by such waste water.
On the other hand, both reactive dyes and direct dyes cannot obtain a proper level of dyeing property without the aid of neutral salts for the reasons described above and the like. In order to dye reactive dyes or direct dyes without the aid of neutral salts, it is necessary to modify the functional groups of the fibers to cations.
For example, WO2016/085099 discloses a method for modifying cellulose to cations using β -chloroethyl-trialkyl ammonium chloride.
However, when a cellulose fiber is modified by covalent bonds with a conventionally known quaternary ammonium cationizing agent, the substantivity of the dye becomes very high, and it is very complicated to obtain the leveling property, which is the largest cause of dyeing failure. For example, the difference between the actual dyeing using neutral salts and the ring dyeing (ring dyeing) phenomenon or color change in the fibers is large, and therefore, considerable adjustment is required.

ADVANTAGEOUS EFFECTS OF INVENTION
When the polymer type cationizing agent according to the present invention is used, the amount of neutral salt such as sodium sulfate used at the time of dyeing of fibers can be reduced, so that corrosion of dyeing machines and other piping caused by the neutral salt electrolyte solution can be suppressed. Further, the dyeing machine can perform effective dyeing by reducing the labor and time for charging the neutral salt into the dyeing machine, improve the washing property of the dyed object due to excessive use of the neutral salt, and maximize the production efficiency by saving water and reducing energy and process time. And, even if a minimum amount of neutral salt is used, the dyeing property is excellent without uneven dyeing such as ring dyeing phenomenon and discoloration.

Detailed Description
One embodiment of the present invention provides a cationizing agent for dyeing fibers represented by the following [ chemical formula 1] or [ chemical formula 2 ].
[ chemical formula 1]
R1Is an amino group, and the amino group,
R2is a polyethylene glycol residue or a polyethylene glycol alkylate residue,
x is an anion with the valence of 1,
a. b and c are the molar ratio of the monomers, a is 0 to 10%, b is 50 to 85%, and c is 15 to 40%.
[ chemical formula 2]
In the above-mentioned [ chemical formula 2],
R3is a polyethylene glycol residue or a polyethylene glycol alkylate residue,
d and e are the molar ratio of the monomers, d is from 5 to 50% and e is from 50 to 95%.
In the [ chemical formula 1]]In the formula, X may be a 1-valent anion, but is not limited thereto, and specifically may be a halogen ion (F)-、Cl-) Sulfate (SO)4 -) And the like.
The cationizing agent for dyeing fibers represented by [ chemical formula 1] or [ chemical formula 2] can reduce the amount of neutral salt used when dyeing fibers with reactive dyes or direct dyes. And, even if a minimum amount of neutral salt is used, it can have excellent dyeing properties without uneven dyeing such as ring dyeing phenomenon and discoloration.
The term "cationizing agent" as used herein refers to a substance for modifying a predetermined substance, for example, a cellulose fiber, into a cation, and is used in combination with a cationic polymer.
The term "reactive dye" used in the present specification is a dye that is fixed by chemically reacting with a fiber during dyeing, and has a reactive group in a dye molecule. Most of the reactive groups used at present are vinylsulfone, triazine, pyrimidine and the like. Reactive dyes are mainly dyes for cotton, hemp, ramie, rayon, silk, korean paper (Hanji), and the like, which are dyed in a dye bath in the presence of alkali by means of covalent bonds with fibers. Is well soluble in water and has superior fastness to direct dyes. And has the advantages of bright color, excellent permeability and leveling property and wide dyeable fiber range.
The term "direct dye" as used herein refers to a dye that is directly dyed in a cellulose fiber such as cotton, hemp, or rayon, with a neutral salt such as sodium sulfate or sodium chloride. Chemically, azo compounds are most often composed of diazo and azide compounds, and sodium sulfonate is bonded to the compounds for water solubility. The direct dye can directly dye fibers such as cotton and the like in a hydrogen bond mode and the like without the help of alkali.
In addition, a large amount of neutral salt of 90g/L or more is generally used in dyeing fibers, and when the polymer cationizing agent of the present invention is used, the amount of the neutral salt can be reduced to 50% or less.
Specifically, the amount of neutral salt used in dyeing the fiber with the polymeric cationizing agent of the present invention can be reduced to 60g/L or less, preferably 50g/L or less, and more preferably 40g/L or less, but is not limited thereto.
The neutral salt may be sodium sulfate (Na)2SO4) But is not limited thereto.
The cationizing agent for dyeing fibers represented by [ chemical formula 1] or [ chemical formula 2] may be a polyethylene glycol allyl ether or a copolymer of polyethylene glycol-substituted (meth) acrylate and diallyldimethylammonium chloride, and may be a random copolymer, for example. The copolymer may be a copolymer polymerized by means of a free radical initiator.
In [ chemical formula 1] of the present invention, the molar ratios a, b and c of the monomers may be, respectively: a is 0 to 10%, 2 to 10%, 3 to 9%, or 4 to 8%, b is 50 to 85%, 55 to 80%, 60 to 75%, or 65 to 70%, and c is 15 to 40%, 20 to 40%, 22 to 38%, or 25 to 35%, but not limited thereto.
In [ chemical formula 2] of the present invention, the molar ratios d and e of the monomers may be, respectively: d is 5 to 50%, 10 to 50%, 15 to 45% or 20 to 40%, e is 50 to 95%, 55 to 90%, 60 to 85% or 65 to 80%, but not limited thereto.
The average molecular weight of the cationizing agent for fiber dyeing represented by [ chemical formula 1] or [ chemical formula 2] may be 1,000 to 200,000g/mol, 2,000 to 150,000g/mol, or 5,000 to 100,000g/mol, but is not limited thereto.
The cationizing agent for fiber dyeing represented by [ chemical formula 1] or [ chemical formula 2] can cationize the surface charge of the cellulose-based fiber by electrostatic attraction and weak ionic binding energy.
Specifically, the bonding between the polymer cationizing agent represented by [ chemical formula 1] or [ chemical formula 2] and the cellulose-based fiber is not chemical (covalent) bonding, but may be physical bonding by electrostatic attraction between polar groups. On the other hand, the physical bond energy with the cellulose-based fiber by electrostatic attraction is smaller as the steric hindrance (steric hindrance) of the substituent of the quaternary ammonium salt is larger. The polymer type cationizing agent is a polymer, and therefore, cannot enter the inside of a cellulose-based fiber such as a cotton fiber, and may be a substance bonded to the surface of the cellulose-based fiber.
In this case, the cellulose-based fiber and the polymer type cationizing agent are bonded to the surface of the fiber by electrostatic attraction, but can be adsorbed and desorbed by the temperature and water during dyeing, and can alleviate the substantivity with the dye.
Further, the cations adsorbed on the fiber surface and the anions of the dye are easily adsorbed and desorbed at the dyeing temperature by the combination formed by substantivity at the initial stage of dyeing, and thus the leveling property can be secured. That is, the high-molecular cationizing agent imparts limited substantivity by physical bonding force, not strong substantivity by chemical (covalent) bonding with the cellulose-based fiber, and thus can overcome the essential problem of difficulty in obtaining leveling property (levelling) due to extremely high substantivity of the dye in the conventional art.
Furthermore, when the conventional cationic polymer encounters a dye having an anionic property, a drastic aggregation phenomenon occurs to convert the dye into an aqueous phase (H)2O Phase) extrapolates or causes the ionic problem of tarring, and, in contrast, the cationizing agent for fiber dyeing of the present invention is used as a cationic agent consisting of [ chemical formula 1]]Or [ chemical formula 2]]The cationic agents for dyeing fibers are shown to minimize the occurrence of such ionic problems.
Another embodiment of the present invention provides a method for preparing the cationizing agent for dyeing fibers.
Specifically, a method for preparing a cationizing agent for dyeing fibers represented by [ chemical formula 1] or [ chemical formula 2], comprising: mixing 10 to 30 parts by weight of polyethylene glycol allyl ether or polyethylene glycol-substituted (meth) acrylate, based on 100 parts by weight of diallyldimethylammonium chloride (DADMAC); 1 to 3 parts by weight of allylamine hydrochloride; and distilled water of 50 to 80 parts by weight, and a step of adding ammonium persulfate (ammonium persulfate) to the monomer mixture to obtain a random copolymer.
The term "monomer" used in the present specification is a low molecular weight substance that becomes a unit forming a high molecular compound by a chemical reaction, for example, poly diallyldimethylammonium chloride is produced by addition polymerization of diallyldimethylammonium chloride, in which case the diallyldimethylammonium chloride is referred to as a monomer of poly diallyldimethylammonium chloride.
The term "monomer mix" used in the present specification is a complex in which one or more monomers are mixed, and for example, a complex in which diallyldimethylammonium chloride and a (meth) acrylate monomer substituted with polyethylene glycol are mixed is referred to as a monomer mixture.
Specifically, the monomer mixture for preparing the cationizing agent for fiber dyeing represented by [ chemical formula 1] may include, based on 100 parts by weight of diallyldimethylammonium chloride: 10 to 30 parts by weight of polyethylene glycol allyl ether; 1 to 3 parts by weight of allylamine hydrochloride; and 50 to 80 parts by weight of distilled water.
And, the monomer mixture for preparing the cationizing agent for fiber dyeing represented by [ chemical formula 2] may include, based on 100 parts by weight of diallyldimethylammonium chloride: 10 to 30 parts by weight of polyethylene glycol-substituted methacrylate or polyethylene glycol-substituted acrylate; 1 to 3 parts by weight of allylamine hydrochloride; and 50 to 80 parts by weight of distilled water.
The cationizing agent for dyeing fibers represented by [ chemical formula 1] or [ chemical formula 2] adds Ammonium Persulfate (APS) as a radical initiator to the respective monomer mixtures formed to initiate polymerization, thereby obtaining a random copolymer.
Yet another embodiment of the present invention provides a method of dyeing fibers comprising: a step of placing the fiber dyeing cationizing agent in a dye bath and pretreating the fiber at 20 ℃ to 100 ℃.
The cationizing agent for dyeing fibers may be pretreated on the fibers for the purpose of modifying the fibers to cations, prior to the step of dyeing the fibers with a reactive dye or a direct dye.
The solid content of the cationizing agent for dyeing fibers of the present invention may be 1 to 90% by weight, 5 to 70% by weight, 10 to 50% by weight, and preferably, may be 15 to 30% by weight, or 20% by weight, but is not limited thereto.
Also, the cationizing agent may be added in an amount of 0.01 to 20 wt%, 0.05 to 10 wt%, 0.07 to 5 wt%, 0.08 to 2 wt%, or 0.09 to 1 wt% compared to the weight of the fiber (owf, on weight fabric).
The fiber pretreatment may be performed at 20 ℃ to 100 ℃, 40 ℃ to 80 ℃, or 50 ℃, for example, 5 to 30 minutes, 10 to 20 minutes, or 15 minutes, but is not limited thereto.
Yet another embodiment of the present invention provides a method of dyeing fibers comprising: a step of dyeing the fiber at 40 ℃ to 100 ℃ after putting the cationizing agent for fiber dyeing, neutral salt and dye into a dye bath.
The cationizing agent for fiber dyeing of the present invention may be added together in the step of dyeing the fiber with a reactive dye or a direct dye. That is, in the case of fiber dyeing, an additional pretreatment step for cationic modification of the target fiber is not required, and dyeing can be performed by simultaneous treatment in one dye bath.

When the neutral salt is used together with the cationizing agent for fiber dyeing of the present invention, the neutral salt may be used at a concentration of 60g/L or less, 50g/L or 40g/L or less, but is not limited thereto.
The fiber dyeing using the composition for fiber dyeing of the present invention may be performed at 40 to 100 ℃, 50 to 70 ℃, or 60 ℃, but is not limited thereto, and may be performed for, for example, 10 to 90 minutes, 30 to 80 minutes, or 60 minutes, but is not limited thereto.
The fiber dyed with the fiber dyeing composition of the present invention may be dyed after immersion in a dye bath under predetermined conditions of temperature and time before dyeing the target fiber or after pretreatment by pad-dry-cure (PDC).
