BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deep-colored polyester fiber fabric and a method for producing the same.

0002

BACKGROUND OF THE INVENTION Many studies have been made to improve deep hues, particularly black bathochromic properties, particularly in polyester fibers. For example, a compound with a low refractive index is applied to a dyed fiber fabric, such as a fluorine-based treatment agent (such as JP-A-57-176275), a silicone-based treatment agent (
There is a method of coating the fiber surface with a urethane-based treatment agent (Japanese Patent Application Laid-Open No. 57-29682), etc.). Although the level of deep coloring can be improved by these means, problems such as a decrease in bathochromic degree due to dry cleaning washing processing and color bleeding due to dye bleed-out are likely to occur as the bathochromic property improves. However, there was a problem with the durability of the bathochromic effect. Another problem is that when an antistatic agent is used to prevent the adhesion of dust and the like, the bathochromic properties are reduced.

On the other hand, there is a method of forming fine irregularities on the fiber surface to prevent diffuse reflection of light on the fiber surface and aim at deepening the color.As this technical means, polyester fibers containing a microporous forming agent are used. Method of removing microporous agent by alkali treatment (Japanese Patent Application Laid-Open No. 120728/1984, etc.)
There is also a method of plasma etching the fiber surface to form fine irregularities (Japanese Patent Publication No. 11709/1982, Japanese Patent Publication No. 37225/1989, etc.). Furthermore,
There is also a method in which textile products are treated in advance with a compound with a low refractive index, and then treated with low-temperature plasma (Japanese Patent Laid-Open No. 1986-9).
7490, etc.). By forming fine irregularities on the fiber surface using these methods, deep coloring can also be improved, and especially when the surface is coated with a compound with a low refractive index, the bathochromic degree can be considerably improved. It is easily destroyed and, for example, when fabrics are rubbed together or tangled during washing, the bathochrome effect tends to deteriorate significantly, and it cannot be said that the bathochrome durability is necessarily at a sufficient level. In addition, in terms of color fastness, there was a problem in that the level of fastness to rubbing was particularly low.

0004

Problems to be Solved by the Invention The present invention solves the problems with conventional deep coloring technical means, particularly the durability and abrasion fastness of the bathochrome effect at a high level of bathochrome, to a level that poses no problem in practice. It is an object of the present invention to provide an improved dyed polyester fiber fabric.

[0005]

[Means for Solving the Problems] The present invention provides a deep-colored dyed polyester fiber fabric whose surface is coated with silica fine particles having an amino group and amino-modified silicone through a polyepoxide compound. The present invention provides a polyester fiber fabric and a method for producing the same.

The present invention is directed to dyed polyester fibers. Here, dyed polyester fiber refers to one that has been heat-treated using a dye at a high temperature of 100°C or higher. Generally, a disperse dye is used as the dye, but in the case of modified polyester fiber, a cationic polyester fiber is used. Dyes or acid dyes may also be used. Moreover, as a dyeing method, any of dip dyeing, thermosol printing, and textile printing can be applied. The polyester fiber in the present invention includes glycol components such as ethylene glycol, trimethylene glycol, and 1,4-butanediol, and terephthalic acid,
Polycondensates with dicarboxylic acid components such as isophthalic acid, malonic acid, and succinic acid, polyester copolymers in which other third components are copolymerized as part of the glycol component or dicarboxylic acid component, or these polyester polymers and other polymers.

[0007] The polyester fibers may contain optional additives such as catalysts, color inhibitors, heat resistant agents, flame retardants, antioxidants, inorganic fine particles, etc., as required. In the present invention, polyester fibers may be used by blending, inter-knitting, inter-weaving, etc. with natural fibers such as cotton and wool, regenerated fibers such as rayon and acetate, and synthetic fibers other than polyester, as necessary. do not have. Further, in the present invention, polyester fibers that have been subjected to alkali weight loss treatment can be used, and it is also possible to exhibit a sufficient deep color effect.

[0008] The polyepoxide compound used in the present invention is preferably a compound containing at least two epoxy groups, more preferably three or more epoxy groups in one molecule in an amount of 0.2 g equivalent or more per 100 g of the compound. reaction products of polyhydric alcohols such as ethylene glycol, glycerol, sorbitol, pentaerythritol, and polyethylene glycol with halogen-containing epoxides such as epichlorohydrin;
Reaction products of polyhydric phenols such as resorcinol/bis(4-hydroxyphenyl)dimethylmethane, phenol/formaldehyde resin, and resorcinol/formaldehyde resin with the above halogen-containing epoxides, unsaturated compounds with peracetic acid or hydrogen peroxide, etc. Polyepoxide compounds obtained by oxidizing 3,4-epoxycyclohexyl compounds, such as 3,4-epoxycyclohexene epoxide, 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexenecarboxylate, bis(3,4- Examples include epoxy-6-methyl-cyclohexylmethyl)adipate. Among these, reaction products of polyhydric alcohols and epichlorohydrin, ie, polyglycidyl ether compounds of polyhydric alcohols, are particularly preferred because they exhibit excellent performance.

[0009] When the number of epoxy groups contained in one molecule is three or more, it is preferable because it has particularly good affinity with polyester fibers and provides a deep color finishing agent that is later processed with excellent deep color durability. Furthermore, when polyepoxide compounds are synthesized, it is common for slight isomers and compounds containing chlorine to be present. Although the mechanism by which this chlorine-containing polyepoxide compound reacts with polyester fibers is not known, it is presumed that electrical bonding is at play, and the polyepoxide compound of the present invention preferably contains chlorine. Here, the total chlorine amount is a value expressed in weight% by decomposing covalently bonded chlorine with metallic sodium and quantifying the chlorine amount using the Holhardt method, and the total chlorine amount contained in the polyepoxide compound of the present invention is Preferably 6 from the viewpoint of bathochromic durability.
It is at least 10% by weight, more preferably at least 10% by weight.

[0010] Such a polyepoxide compound is usually preferably used as an emulsion. To make an emulsion or solution, for example, such a polyepoxide compound can be prepared as it is or if necessary, dissolved in a small amount of solvent.
Emulsification or dissolution is performed using a known emulsifier such as sodium alkylbenzenesulfonate, dioctylsulfosuccinate sodium salt, nonylphenol ethylene oxide adduct, and the like.

In the present invention, the amount of the polyepoxide compound used is not particularly limited, but in order to impart durable bathochromic properties to the polyester fiber, it is used in an amount of 0.1 to 10% by weight based on the polyester fiber. Things are exemplified. If the amount of polyepoxide compound used is less than 0.1% by weight, a durable deep color effect cannot be obtained;
If it exceeds 0% by weight, the bathochromic property and its durability will not necessarily be improved, and hand and other defects will occur, which is not preferable.

[0012] The processing temperature for the polyepoxide compound is preferably in the range of 70 to 130°C, more preferably in the range of 80 to 100°C. If the treatment temperature with the polyepoxide compound is less than 70°C, the durability of bathochromic properties will be insufficient, while if it exceeds 130°C, the durability of these properties will not necessarily be further improved, but may even deteriorate. Therefore, it is preferable to process within the above range. Moreover, the processing time for the polyepoxide compound is preferably 1 minute or more, and more preferably 5 to 60 minutes. As long as such conditions are met, the treatment method may be a high-temperature continuous treatment or a so-called batch method in which the fibers are introduced from room temperature, then heated and treated at a predetermined temperature.

Next, the silica fine particles having an amino group used in the present invention preferably have an average particle diameter of 1 μm.
It is a compound obtained by reacting the following finely powdered silica with a solution in which aminosilane is dissolved in water or a lower alcohol such as methanol. If the average particle diameter of the silica fine particles having an amino group exceeds 1 μm, the bathochromic effect will be insufficient and the texture will be rough and hard.

[0014] Fine silica particles having an amino group can be used, for example, in Aerosil #200 (manufactured by Nippon Aerosil Co., Ltd.) with gamma (
It can be easily obtained by contacting a solution of 2-aminoethyl)-aminopropyltrimethoxysilane or aminopropylethoxysilane dissolved in water or a lower alcohol such as methanol by spraying or the like. here,
The ratio (weight ratio) of Aerosil #200 to aminosilane is generally preferably 100:0.01 to 100:100, more preferably 100:0.1 to 100:3.

These silica fine particles having amino groups can be dissolved in organic solvents such as toluene, xylene, n-hexane, heptane, acetone, methyl ethyl ketone, methyl isobutyl ketone, ethyl acetate, butyl acetate, mineral turpentine, and isopropyl alcohol. A treatment solution may be prepared and applied to the polyester fiber fabric by spraying, mangling, dipping, etc., or it may be self-emulsified as it is, or it may be mixed with a suitable emulsifier, such as a sulfate ester salt of a higher alcohol, or an alkylbenzene sulfonate. , higher alcohol polyoxyalkylene adduct, higher fatty acid polyoxyalkylene adduct, higher fatty acid sorbitan ester, etc., and may be applied to the polyester fiber fabric by methods such as spraying, mangling, and dipping.

In the present invention, the amount of silica fine particles having amino groups used is preferably 0.1 to 10% by weight, more preferably 0.5% by weight, based on the polyester fiber fabric.
~3% by weight. The larger the amount used, the higher the deep color effect will be, but on the other hand, problems will arise such as the durability is impaired, the fastness to rubbing is greatly reduced, and the texture becomes rough and hard. On the other hand, if it is less than 0.1% by weight, it is not preferable because the deep color effect is poor.

Next, it is preferable that the amino-modified silicone used in the present invention is represented by the following general formula [I]. (In the formula, m is an integer of 5 to 500, n is 1 to 50, R
represents a hydrogen atom, a methyl group or an ethyl group, and R' represents a divalent hydrocarbon group. )

In the general formula [I], if m is less than 5, it is difficult to synthesize a stable compound, and if it exceeds 500, it is difficult to obtain the desired performance of the present invention. The range is 200. Also, n is 1 to 50
If n is 0, the durability of the bathochromic effect cannot be obtained, while if n exceeds 50, processing tends to become unstable.

In the general formula [I], R must be a hydrogen atom, a methyl group, or an ethyl group; other alkyl groups are difficult to manufacture and the durability of the bathochrome effect is also poor. Further, R' is a divalent hydrocarbon group, such as -CH2 -, -(CH2)2 -, -(CH2)
3-,-(CH2)4-,-CH2CH(CH
3) Alkylene groups such as CH2 -, -(CH
2) Alkylenearylene groups such as 2-C6H4- are exemplified. Among these, the propylene group is the most common.

These amino-modified silicones are produced by using, for example, octamethyltetrasiloxane and gamma-(2-aminopropyl)trimethoxysilane as raw materials, and mixing these raw materials with an alkali metal catalyst such as sodium hydroxide or potassium hydroxide. , can be easily prepared by heating the mixture to a temperature of 70 to 120°C high enough to cause equilibration of the raw materials (rearrangement of siloxane units).

These amino-modified silicones can be dissolved in organic solvents such as toluene, xylene, n-hexane, heptane, acetone, methyl ethyl ketone, methyl isobutyl ketone, ethyl acetate, butyl acetate, mineral turpentine, and isopropyl alcohol to form a treatment solution. Prepare
It may be attached to the polyester fiber fabric by methods such as spraying, mangling, or dipping, or it may be self-emulsified as it is, or it may be coated with a suitable emulsifier, such as higher alcohol sulfate ester salt, alkylbenzene sulfonate, or higher alcohol polyoxyalkylene addition. It may be emulsified with a higher fatty acid polyoxyalkylene adduct, a higher fatty acid sorbitan ester, and attached to the polyester fiber fabric by spraying, mangling, dipping, or other methods.

In the present invention, the amount of amino-modified silicone used is preferably 0 to the polyester fiber fabric.
．． 05 to 1% by weight, more preferably 0.1 to 0.5% by weight. If the amount of amino-modified silicone used is less than 0.05% by weight, the deep color effect will be insufficient;
Exceeding this is not preferable because the texture of the processed fabric becomes unnecessarily soft and defects occur in terms of color fastness.

The refractive index of the amino group-containing silica fine particles and amino-modified silicon of the present invention is preferably a low refractive index of 1.5 or less. Since the refractive index of polyester fiber is 1.7, even if the refractive index exceeds 1.5 and is about 1.6, bathochromic property is recognized, but it is insufficient. More preferably, when the refractive index of the amino group-containing silica fine particles and amino-modified silicon is 1.4 or less, excellent bathochromic properties are observed.

The method for producing the deep-colored polyester fiber fabric of the present invention includes (1) heat-treating the dyed polyester fiber fabric with a treatment solution containing a polyepoxide compound, and then treating the polyester fiber fabric with silica fine particles having amino groups. and treated with an amino-modified silicone represented by the general formula [I], or (1) heat-treated the dyed polyester fiber fabric with a treatment solution containing a polyoxide compound, and then treated the polyester fiber fabric with a silica having an amino group. A method of treating with fine particles and then treating with an amino-modified silicone represented by the general formula [I] can be mentioned.

In the production method of the present invention, unless the dyed polyester fiber fabric is first pretreated with a polyepoxide compound, the effects of the invention (improvement in the durability of the deep color effect and abrasion fastness) cannot be achieved. Furthermore, when pre-treating with the polyepoxy compound and then treating with silica fine particles and amino-modified silicon, if the treatment is first treated with amino-modified silicon and then treated with silica fine particles, the effect of improving bathochromic properties is small. This is because the amino-modified silicone has some water repellency, so that the silica fine particles cannot be applied to the polyester fiber fabric.

Among the above-mentioned manufacturing methods, (2) When silica fine particles and amino-modified silicone are treated in the same bath, the effect of improving the bathochromic property is good. Furthermore, in the case of (2) treatment with silica fine particles and finally treatment with amino-modified silicone, the effect of improving the bathochromic property is particularly large.

[0027]

[Operation] The present invention is characterized in that a polyester fiber fabric is pretreated with a treatment liquid containing a polyepoxide compound. Due to this pretreatment, it is not clear how the polyepoxide compound adheres to the polyester fiber fabric, but the initial deep color effect remains intact and is highly durable even after washing, dry cleaning, and abrasion treatments. It is presumed from this that the polyepoxide compound is firmly attached to the surface of the polyester fiber, or that it has partially penetrated into the interior of the polyester fiber, so that the silica fine particles and amino-modified silicone having amino groups that are added later are It is thought that the polyester fiber surface is coated with good durability by reacting with the epoxy group of the polyepoxide compound.
