DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a textile product comprising a brushed fabric suitable for interior furniture such as clothing and upholstery, interior materials for vehicles, shoe outerwear, shoe lining, bag outerwear, bags and miscellaneous goods. More specifically, since the organic solvent is not used in the processing step, the agent does not remain even in the fabric, and it corresponds to sick house syndrome, non-formaldehyde conversion, non-organic solvent conversion, which has recently become a topic, In addition, the present invention relates to a textile product made of a suede-like polyester brushed fabric that is easy to lose its shape and is excellent in shape retention because it is formed of a woven or knitted fabric and that is friendly to the living environment.

2. Description of the Related Art Brushed fabrics made of polyester fibers,
In particular, in the field of products called artificial suede, short-fiber nonwoven fabrics and long-fiber nonwoven fabrics, which are basically two-dimensional structures having no directionality, exist as base fabrics, and after raising the nonwoven fabric, polyurethane resin Impregnated with resin or acrylic resin, etc., and used as a laminated structure by physical treatment such as resin bonding or needle punching for chair upholstery, etc. to maintain strength, or as it is for miscellaneous goods And so on. Many of the base fabrics are made of ultrafine fiber forming type fibers, and a polymer having poor compatibility with each other is radiated by a complex spinning method, or a cross-sectional shape obtained by laminating in a multi-layer split shape,
Using a static kneading element, a plurality of types of molten polymers are discharged in a dispersed state to form a fiber, and then a two-dimensional structure is formed. Then, one is dissolved using an organic solvent or one is swollen to split and ultrafine. There is a need. However, in the above method, the process of making the fibers ultrafine is indispensable, and since the wastewater from the factory contains a large amount of the organic solvent, the burden on the environment is large. It is also not preferable.

[0003] As a special spinning method, a non-woven fabric by a flash spinning method in which a polymer is discharged in the presence of a solvent to make it ultrafine or a melt-blowing method in which a molten polymer is explosively discharged by using a high-pressure gas to make it ultrafine are widely used. However, the former has a problem of the residual of the organic solvent due to the use of the polymer solvent, and the latter can obtain fibers in a region called ultra-fine fibers, but can obtain a dark color even when dyed. It has a problem that color development is difficult.

When a suede-like raised fabric is obtained, a brushing treatment is generally performed after impregnating a base material with a polyurethane resin. However, when the polyurethane resin is applied, dimethylformamide, dimethylacetamide, dimethylsulfoxide and the like are used in a wet formulation. In general, a method using a polar organic solvent such as diethylacetamide is used, and the feeling and swelling are preferably finished. However, it is not preferable in view of the waste liquid of the factory and the solvent remaining in the fabric. Dry formulations use large amounts of volatile organic solvents with low boiling points, such as toluene, xylene, acetone, and methyl ethyl ketone. It is highly possible that the solvent remains.

[0005] As described above, non-woven fabrics based on spunbonding, meltblowing, flash spinning, etc. are mainly used for the base fabric, and are characterized by low production costs, quick delivery, and no directivity in mechanical properties. But,
Since the two-dimensional structure is formed by entanglement of single fibers, the tear strength is moderate, but the elongation is poor, and residual strain easily occurs, so twisting in multiple directions such as shoe lining material, shoe surface material, etc. For applications in which various strains such as bending, elongation and the like occur, it was unsuitable in terms of consumption performance. Further, it has poor drapability, and is particularly unsuitable for applications requiring a beautiful silhouette on a curved surface or a sewn portion, such as an upholstery application, a general clothing application, or an application that easily loses its shape.

[0006]

A solvent or dispersant used for impregnating a woven or knitted fabric structure with a polyurethane resin in consideration of simplification of an artificial leather manufacturing process, prevention of environmental pollution, and product safety. Was changed from an organic solvent system to an aqueous system, and conventionally, an organic solvent having a fiber dissolving ability or a swelling ability was used at the time of ultrafine fiberization. A first object is to prevent pollution and to suppress harmful substances remaining in products. It is a second object of the present invention to provide a fibrous product made of a polyester brushed fabric that is excellent in strength and visual by changing a two-dimensional structure serving as a base fabric from a conventional nonwoven fabric to a woven or knitted fabric. Things.

[0007]

The present invention has the following arrangement. A brushed fabric containing 5 to 30% by weight of a polyurethane resin and 1 to 5% by weight of an ultraviolet absorber comprising at least one selected from benzotriazine, benzotriazole, benzophenol, benzophenone and derivatives thereof. A textile product comprising: a fabric obtained by directly melt-spinning a polyester having ethylene terephthalate as a main repeating unit to obtain a multifilament yarn, and weaving and knitting using the multifilament yarn in at least a part thereof. 5 ppm. By a GC-MS method. A fiber product made of a polyester raised fabric that does not detect the above-mentioned aromatic, aliphatic and alicyclic organic solvents and other polar organic solvents and satisfies the following requirements. Proportion of fibers having a single yarn fineness of 0.35 dtex or less with respect to the brushed fabric ≧ 50% by weight

The polyester multifilament yarn used for the raised fabric of the present invention is obtained by a usual melt spinning method, and directly spins a single fiber fineness of 0.35 dtex or less without using a composite spinning method. Is gained by: Although there is no particular limitation on the polyester to be used, the intrinsic viscosity [η] of which ethylene terephthalate is the main repeating unit is 0.1.
Desirably, it is a polymer of 45 to 0.70. Further, inorganic fine particles such as titanium dioxide, barium sulfate, and silicon dioxide may be contained as needed. Of course, there is no limitation on the cross-sectional shape, and in addition to a round cross-section, a polygonal cross-section, a flat cross-section, a hollow cross-section, a different shaped cross-section, or the like, may be used in an appropriate combination depending on the application.

[0009] Among the polyester multifilament yarns constituting the brushed fabric of the present invention, fibers having a single yarn fineness of 0.35 dtex or less are 50% by weight or more, more preferably 60% by weight or more, and further preferably 70% by weight of the brushed fabric. % Is preferable. If the proportion of fibers having a single yarn fineness of 0.35 dtex or less is less than 50% by weight, the fluffy fluff cannot sufficiently cover the fabric surface even during brushing or brushing, and the texture of the woven or knitted fabric becomes conspicuous. Sisters,
Finishing is not desirable for appearance quality. The upper limit is not particularly limited, but if the fiber having a single yarn fineness of 0.35 dtex or less is 90% by weight or more, the physical strength of the brushed fabric cannot be sufficiently maintained. It is preferable to keep it to the extent.

In obtaining the raised fabric of the present invention, the wool-forming fluff mainly forming the fabric surface preferably has a smaller fineness in terms of appearance and quality, and a single-fiber fineness of 0.35 dtex or less, more preferably It is preferable that the single yarn fineness is 0.23 decitex or less. The lower limit of the single-fiber fineness is not particularly limited, but in order to obtain ultrafine fibers without any chemical treatment, the direct melt-spinning is limited to about 0.12 decitex, and Those with fineness are difficult to stably discharge and stretch stably. Therefore, the single-fiber fineness is preferably from 0.12 to 0.35 dtex, more preferably from 0.12 to 0.23 dtex.

When the polyester multifilament yarn directly melt-spun is subjected to weaving and knitting as a false twist yarn, the sensation of turbulence peculiar to raw yarn is suppressed.
It is preferable that at least a part of the 5 dtex filament is false-twisted. The false twisting method is not particularly limited, and can be carried out using a commercially available model such as a belt false twister, a friction disk false twister, and a pin false twister. The weaving and knitting is not particularly limited to a model, and can be carried out by using a known model.

The polyurethane resin used in the raised fabric of the present invention is not particularly limited, but is preferably a diisocyanate such as aliphatic diisocyanate or alicyclic diisocyanate and a monomer such as polytetramethylene glycol or polypropylene glycol as monomers. A polymer obtained by polymerizing a glycol and an aliphatic diamine is exemplified.

The ultraviolet absorber used in the present invention is one which absorbs at least one selected from benzotriazine, benzotriazole, benzophenol, benzophenone and derivatives thereof into fibers in the same step as dyeing. It is necessary that the compound be a low-molecular compound capable of absorbing light energy of 400 nm or less and converting it to heat energy or the like. By containing the UV absorber in the fabric in an amount of 1 to 5% by weight, deterioration in light fastness is suppressed even in the case of dispersion dyeing of polyester ultrafine yarn, and there is no discoloration and no discoloration even when irradiated with UV light for a long time in a high temperature environment. It can be a fabric. If the content of the ultraviolet absorber exceeds 5%, it is difficult to apply even the above low molecular weight compounds by the exhaustion method, and melt spinning is performed in a state where the compound is kneaded in advance in a polymer. Although it is necessary, the spinning condition is significantly impaired, which is not preferable. On the other hand, if the content of the ultraviolet absorber is less than 1% by weight, the above-mentioned light fastness is not satisfactory, causing color fading and discoloration.

After weaving and knitting the base fabric for obtaining the brushed fabric of the present invention, scouring, relaxing and dyeing treatments are performed by known methods. Dyeing is carried out under a high pressure condition of 130 ° C. or more in order to exhaust the disperse dye and the ultraviolet absorber. There is no particular limitation on the machine used in the dyeing step, but the use of a jet dyeing machine is particularly preferred. After dyeing, carry out reduction washing with sodium hydroxide and thiourea dioxide to remove excess disperse dye and UV absorber, hot water washing, acid neutralization, water washing, and then charge by padding dry method An inhibitor, a leveling agent and the like are provided. The application of the antistatic agent and the smoothing agent contributes to the stabilization of the process of the next step of raising the needle cloth, and without the chemical treatment, the cloth releasability is extremely deteriorated and the brush is uniformly raised. Becomes difficult. If the disperse dye alone does not achieve the target color tone in terms of density or the dyeing fastness is significantly deteriorated, coloring of the fiber surface with an organic pigment or an inorganic pigment such as a pigment resin color may be used in combination.

The cloth which has been subjected to the raising treatment and the shearing is set in a spread state by using a heat setter, and the rough cloth is removed, the texture is corrected, and the width is adjusted to form a base cloth for polyurethane resin processing. The base fabric is continuously heated to 100 ° C. or more after being applied with an aqueous polyurethane emulsion by slit mangle or padding mangle.
Dry at a temperature below 0 ° C. The drying temperature needs to be 130 ° C. or less, preferably 120 ° C. or less, in consideration of dye transfer and sublimation to the polyurethane resin. In terms of drying efficiency, it is desirable to perform the treatment at a high temperature in a short time, but drying in a region exceeding 130 ° C. is undesirable because the transfer and sublimation of the disperse dye becomes extremely poor, and a low-temperature treatment of less than 100 ° C. If a long processing time is required, a commercial process speed cannot be obtained. The brushed fabric after drying the polyurethane resin is once wound into a roll shape. In order to promote intermolecular crosslinking of the polyurethane resin and to maintain the strength of the brushed fabric obtained, the brushed fabric is kept at 30 to 50 ° C. in an environment of 30 to 50 ° C. More preferably, the aging treatment is performed for up to 72 hours.

The solid content ratio of the polyurethane resin to the brushed fabric of the present invention is preferably 5% by weight or more and 30% by weight or less, more preferably 10% by weight or more and 20% by weight or less. The aqueous polyurethane emulsion is applied to the base fabric in an appropriate amount by the above-mentioned mangle. However, if the solid content of the resin is less than 5% by weight, an appropriate flesh feeling and sufficient strength cannot be maintained. If it exceeds the range, the resin concentration cannot be increased by mangle unless the resin concentration is increased.
If the resin concentration is increased, the water-based polyurethane emulsion liquid will thicken and cannot be uniformly applied to the base fabric, but the resin will adhere only to the surface due to poor permeability to the fabric. It does not penetrate into the inside of the fabric, and the brushed fabric is stuck and finished only with a waistless feeling. The aqueous polyurethane emulsion liquid can contain an appropriate amount of an antistatic agent, an antifoaming agent, or the like, if necessary. In this case, it is necessary to select and adjust the drug that does not cause gumming up of the liquid, the amount to be applied,
Of course, the stability of the emulsion must also be considered.

After the resin is impregnated into the base fabric and dried, the surface of the fabric is ground using a sanding machine or the like to form a large number of dense hairs. For complete removal, the same reduction washing as that after dyeing is performed. Thereafter, if necessary, a water repellent, an antistatic agent and the like are applied by a padding dry method.
The finishing set is performed in a temperature range of not less than 140 ° C and not less than 140 ° C. Considering the productivity and the prevention of migration and sublimation to the polyurethane resin also for the finishing set, treatment in the above range is preferable, and in the range exceeding 140 ° C., the above-mentioned migration and sublimation fastness becomes extremely poor, and is less than 100 ° C. Within the range, there is no problem in the fastness to migration and sublimation, but the processing time becomes extremely long, which is not preferable in consideration of productivity.

As described above, since the stretchability of the brushed fabric is a nonwoven fabric-based fabric, as described above, the two-dimensional structure is formed by entanglement of the single fibers. Even when impregnated with the polyurethane resin, the elongation recovery rate remains low and the residual strain becomes large. In the present invention, in consideration of the above, since the base fabric is a woven or knitted fabric, the degree of misalignment is small due to the effect of the texture point or the loop of the yarn, and the elongation recovery property is significantly improved in comparison with the nonwoven fabric, and the residual The distortion is also mild. The elongation recovery rate and the residual strain rate are measured by the JIS L-1096 A method, and when the elongation recovery rate is 80% or more, more preferably 85% or more, and still more preferably 90% or more, excellent performance is obtained. It can be a brushed fabric. The residual strain rate is 1
By setting the content to 5% or less, more preferably 10% or less, the set in continuous use is reduced, which is preferable.

The textile product comprising the polyester brushed fabric of the present invention is suitably used for upholstery, car interior materials such as car seats, shoe outer materials, shoe linings, bag outer materials, bags, and other miscellaneous goods. At least one water repellent selected from a wax emulsion type, an acrylic resin paraffin wax type, a metal complex salt type, a silicon type, a fluorine type, an alkyl urea type, a fatty acid amide type, and a paraffin wax type emulsion type is used according to the It may be applied simultaneously with the polyurethane emulsion liquid treatment or in an optional step after the treatment, or may be applied in combination with the aqueous polyurethane emulsion liquid treatment and then applied again in an arbitrary step. In particular, a number of paraffin wax emulsion type water repellents that do not adversely affect the flame retardant effect even when used in combination with a flame retardant are on the market, and are suitable for use in vehicle interior materials and car seat materials. is there. As a treatment method, it is preferable to perform treatment by a pad cure method in a step after the treatment with the aqueous polyurethane emulsion liquid. Regarding the solvent of the water repellent, an organic solvent-based solvent is not preferred, and it is desirable to use an aqueous emulsion type. After applying the water repellent to the fabric by the pad cure method, the fabric is subjected to soaping, blanching, washing with water, and drying to remove excess water repellent components. The curing temperature is not particularly limited, but is preferably in the range of 80 to 140 ° C., and more preferably 80 to 120 ° C. in order to suppress the transfer and sublimation of the dye.
C. is preferred.

As a result of the residual solvent analysis by the C-MS method, no residual solvent was detected, and it was confirmed that the residual solvent was sufficiently usable for clothing use. In the evaluation of the sewability, there was no breakage of the ground yarn, the processability was good, and the quality of the sewn portion was good. However, because it does not use an ultraviolet absorber, it has poor light fastness and fades, and there is a great concern about discoloration.
It has become difficult to develop such materials as vehicle interior materials, car seats, and various clothing applications.

Comparative Example 1 1.25 mol of polytetramethylene glycol having an average molecular weight of 2,000 was mixed with 2.00 mol of dicyclohexylmethane diisocyanate.
While stirring with a homogenizer in the presence of methyl ethyl ketone as a solvent, the mixture was cooled to 35 ° C., and 0.75 mol of isophoroneamine (molar ratio to 2.00 mol of dicyclohexylmethane diisocyanate) was added to accelerate the chain extension reaction to promote the methyl ethyl ketone of polyurethane. A solution was obtained. The solid component (non-volatile content) in the solution is 40%.

As a base material for raising, a base material was prepared in the same manner as in Example 1, and an appropriate amount of a softener, a water repellent and an antistatic agent was adjusted in the solution obtained by the above-mentioned formulation, and the material was impregnated. After that, methyl ethyl ketone as a solvent was dried and removed under a temperature condition of 130 ° C. Methyl ethyl ketone released outside the system was recovered and reused as a solvent. The weight ratio of the solid content of the polyurethane resin to the base fabric subjected to the polyurethane resin processing was 14% by weight. The brushed fabric after impregnation and drying was subjected to an aging treatment at 40 ° C. for 48 hours in order to promote intermolecular crosslinking.

Next, the surface of the polyurethane-containing fabric is ground in a wet state by a combination of fine mesh and forward rotation using a wet gran prix machine manufactured by Sanwa Machinery Co., Ltd. to generate dense fluff on the surface and remove grinding debris. Similar to the reduction washing after the dyeing, the mixture is stirred for 5 minutes using a 0.5 N aqueous solution of sodium hydroxide (solution temperature: 20 ° C. ± 5 ° C.), and then stirred while increasing the temperature to 80 ° C. by adding a thiourea dioxide aqueous solution. Then, reduction washing was performed for 30 minutes. After that, after washing with hot water, acid neutralization with acetic acid, washing with water, and dehydration, use a padding mangle to apply a silicone-based water repellent emulsion,
After drying and fixing at 120 ° C., soaping, blanching, washing with water and preliminary drying were performed, and then drying was performed at 130 ° C. using a heat setter manufactured by Hirano Tecseed Co., Ltd., and the fabric surface was lightly brushed to finish.

The fur was covered on the surface of the woven fabric to give a suede-like raised fabric having an elegant gloss and swelling.
The finished brushed fabric has a fabric thickness of 0.76 mm, a basis weight of 273 g / m ² (0.0273 g / cm ² ), and a weight ratio of fibers having a single yarn fineness of 0.35 decitex or less to the whole raised fabric. It was 66.0% by weight. The properties obtained are summarized in Table 1. As a result of analysis of the residual solvent by the GC-MS method, it was confirmed that methyl ethyl ketone remained as a residual solvent, which was not suitable for use in clothing or living materials. Became inferior. The brushed fabric was used as a surface layer material to prepare a pump for women. There was no breakage of the ground yarn even in the sewing of each part, the processability was good, and the quality of the sewn part and the appearance were good.
