However, the textile products of the prior art have points that need to be improved in order to further enhance stain resistance, texture, and durability.
Specifically, with conventional textile products, for example, even if stain-proofing treatment is applied to fabrics that are used as outer covering materials for sofas and other items that require high stain resistance, stains do not penetrate into the woven structure. In some cases, dirt could be pushed inside the fabric through the gaps, making it difficult to remove the dirt.

In particular, when a backing resin layer is formed by applying acrylic resin processing to the back side of the fabric to ensure physical properties such as tearing, if dirt adheres to the backing resin layer, the dirt becomes entangled with the backing resin layer and becomes difficult to remove. I end up.

The present invention has been made in view of the above circumstances, and its purpose is to provide a textile product that has excellent stain resistance, a suitable texture, and is highly durable, and a method for manufacturing the same. It is in.

Hereinafter, textile products according to embodiments of the present invention will be described in detail based on the drawings.
FIG. 1 is a sectional view showing a schematic configuration of a textile product 1 according to an embodiment of the present invention.
Referring to FIG. 1, a textile product 1 has a textile skin material 2 that covers the surface of furniture or the like. Specifically, the skin material 2 constitutes the skin of, for example, sofas used in homes and offices, sofas of contract furniture used in large quantities in hotels, halls, etc., and other various interiors.

Since the textile product 1 used for the above-mentioned sofa etc. may not be able to be removed from the sofa etc. and washed, it is required to have excellent stain resistance so that attached dirt can be easily removed. Furthermore, the skin material 2 used for these sofas and the like is required to have an excellent texture that is comfortable to sit on. Furthermore, the textile product 1 is required to have surface strength that can withstand long-term use, and is required to have anti-snacking properties that can withstand scratching by the claws of pets such as cats.

However, it has been difficult to satisfy all of the above requirements. The textile product 1 solves this problem and exhibits the excellent effects of having excellent stain resistance, a suitable texture, and high durability.

The skin material 2 is a fabric such as a woven fabric, a nonwoven fabric, or a knitted fabric made of synthetic fiber. Examples of the synthetic fibers that can be used as the material for the skin material 2 include polyester fibers, polypropylene fibers, and polyamide fibers such as nylon, with polyester fibers being particularly preferred.

The fabric used as the skin material 2 is preferably a woven fabric, specifically a plain weave. In particular, it is preferable that the weft yarns of the skin material 2 are formed from threads with fluff and filaments, such as mole yarns or pseudo-mole yarns.

Specifically, the weft yarns of the skin material 2 are formed from molle yarns or pseudo-molle yarns, and the fluff and filaments of the molle yarns or pseudo-molle yarns are ultrafine fibers of 75 denier 72 filaments to 150 denier 144 filaments. It is a counted thread. The structure of the fabric using such thin fluff and filaments can promote capillary action and make it easier to remove dirt. Furthermore, the skin material 2 can be finished with a very soft feel to the touch, resulting in a textile product 1 with a good texture.

The thickness of the molle yarn or pseudo-molle yarn constituting the weft of the skin material 2 is preferably from 1/3.5 to 1/6 count, and the number of threads is preferably from 15 to 25 per inch. With such a configuration, dirt does not penetrate deep into the textile product 1 and stays on the surface, resulting in excellent stain resistance. That is, by increasing the number of threads that are threaded with thin threads, etc., it is possible to suppress the penetration of dirt and improve the stain resistance. In addition, by increasing the number of threads that are driven, it is possible to reduce the skipping of threads and improve the snagging resistance. In addition, the texture of the skin material 2 can be improved.

The warp threads of the skin material 2 are, for example, regular threads, malleable threads, or pseudo-mall threads. When regular yarn is used as the warp, the thickness of the regular yarn is 150 to 950 deniers, and the number of warps is 90 to 130 yarns/inch.

When a molle yarn or a pseudo-molle yarn is used for the warp, the thickness thereof is preferably 1/3.5 to 1/6 count, and the number of yarns used is preferably 15 to 20 yarns/inch. In addition, the fuzz and filaments of the mole yarn or pseudo-mole yarn used for the warp are ultrafine fibers of 75 denier 72 filaments to 150 denier 144 filaments, similar to the mole yarn or pseudo mole yarn constituting the weft described above. Counted threads are preferred.

Specifically, on the surface of the skin material 2, a polyester resin 3 as a resin containing a hydrophilic group and a fluororesin 4 as a resin containing a hydrophilic group and a water-repellent group are attached.

The polyester resin 3 is attached to the threads on the surface side of the skin material 2 in an SR processing step S5 (see FIG. 2) or S102 (see FIG. 3), which will be described later. The fluororesin 4 is attached to the surface side of the polyester resin 3 by a weak water repellent treatment step S7 (see FIG. 2) or S106 (see FIG. 3), which will be described later.

Due to the structure in which polyester resin 3 and fluorine resin 4 are combined on the surface side of the skin material 2, excellent stain resistance is obtained by taking advantage of hydrophilicity and water repellency, and the fiber has a good texture and is highly durable. product is obtained.

Further, the backing resin layer does not need to be formed on the back side of the skin material 2. That is, the textile product 1 does not require backing processing for providing a backing resin layer. The skin material 2 can meet the physical properties of upholstery even if no backing resin layer is formed. Thereby, it is possible to eliminate the adhesion of dirt to the backing resin layer and improve the stain resistance. In addition, the fabric can be made flexible and have an excellent texture.

The fuzz and filaments of the full dalmol yarn are 75 denier and 72 filaments.

On the surface of the skin material 2, a polyester resin 3 (see Figure 1) as a resin containing a hydrophilic group and a fluororesin 4 (see Figure 1) as a resin containing a hydrophilic group and a water-repellent group are attached. are doing.

The polyester resin 3 was attached by the SR processing step S5 of the piece dyeing process shown in FIG. 2, and the water-absorbing SR processing agent and catalyst described above were used as the SR processing agent. The stock solution pH of the water-absorbing SR processing agent used was 5, the viscosity was 100 mPa·s or less/25°C, and the aggregation temperature was 62°C/0.5% soln. It is. The pH of the catalyst stock solution is 8, and the viscosity is 100 mPa·s or less/25°C.

The SR processing step S5 was performed by immersing the skin material 2 in an aqueous solution containing a dye and an SR processing agent with a concentration of 5%. The temperature of the processing aqueous solution in the processing tank was 125° C., and the immersion time was 30 minutes.

The fluorine-based resin 4 was attached by the weak water repellent finishing step S7 of the piece dyeing process shown in FIG. 2, and the above-mentioned fluorine-based SR finishing agent was used as the finishing agent. The weak water repellent finishing step S7 was performed by a padding method, using 55 g/L of a fluorine-based SR finishing agent, 2 g/L of a melamine resin, 2 g/L of a catalyst, and 12 g/L of a blocked isocyanate-based crosslinking agent. The passage speed of the test fabric in the processing tank is 15 m/min. Further, the drying conditions were 120°C for 2 minutes, and the curing conditions were 170°C for 2 minutes.

The test fabric of Textile Product 1 completed by this method had an excellent texture and was very soft to the touch. Moreover, the test fabric of textile product 1 clears the voluntary standard value of the snacking test. In other words, it has been confirmed through a snacking test that it has excellent performance against scratches by pet nails and the like.

Contaminants were attached to the test fabric of textile product 1 completed through the above steps in order to confirm the stain resistance. The attached test contaminants are chili oil in the upper left part A1 of the textile product 1 shown in Figure 4, ballpoint pen ink in the upper right part B1, red wine in the lower left part C1, and sauce in the lower right part D1. It is. After applying the contaminant, a resin plate and a 500 g weight were placed on the stained area of the test fabric and left for 1 minute.

Contaminants adhering to the test fabric were then wiped off with a paper towel or tissue. Next, using a cloth material such as a towel wetted with water or a 10-fold diluted neutral detergent, or a toothbrush or sponge, lightly touch the towel or the like against the surface of the test fabric of Textile Product 1 to remove dirt. was removed. Next, the contaminants and neutral detergent were washed away with water, and the moisture was wiped off with a dry towel. The outer skin of the test fabric was then dried and the stain removal rate and surface changes were observed.

FIG. 5 is a photograph showing the results of an antifouling test of the textile product 1 according to an example of the present invention. In the antifouling test, the results of which are shown in Figure 5, only water was used to clean the test fabric. In Figures 5 to 7, the symbol ◎ in the results column indicates that most of the dirt has been removed, the symbol ○ indicates that the color has slightly faded, and the symbol △ indicates that the stain has become lighter but The symbol "x" indicates that the stain is visible, and the symbol "x" indicates that the stain has not been removed.

As shown in FIG. 5, by washing the textile product 1 to which the contaminant had adhered, almost all of the contaminant that had adhered to it could be completely wiped off. In this way, the excellent antifouling properties of the textile product 1 could be confirmed.

In addition, in the test fabric of Textile Product 1, it was possible to remove many contaminants by soaking the cloth material to wipe off the contaminants with water. Particularly, when cleaning is performed immediately after liquid contaminants have adhered, almost all of the adhered contaminants can be removed simply by wiping with a cloth.

Then, as in the above-mentioned antifouling test, if water is dropped near the contaminant on the surface of the textile product 1, the contaminant can be wiped off even better. When water is dripped onto the surface of the textile product 1, the fibers containing the polyester resin 3 (see Figure 1) and the fibers on the surface side containing the fluororesin 4 (see Figure 1) are replaced, and the polyester resin 3 and the fluororesin are replaced. The hydrophilic group contained in 4 and the water-repellent group contained in fluororesin 4 can make contaminants stand out. This allows contaminants to be thoroughly removed.

FIG. 6 is a photograph showing the results of an abrasion test of the textile product 1 according to an example of the present invention and an antifouling test after the abrasion test. In the abrasion test and the antifouling test after the abrasion test shown in FIG. 6, the Taber abrasion test at 1000 revolutions was performed on the test fabric of the textile product 1 prepared in the same manner as the above-mentioned antifouling test. As a result, the test fabric was confirmed to have abrasion resistance, with no surface yarn breakage or the like.

After performing the Taber abrasion test, contaminants are applied to the test fabric using a method similar to the stain resistance test described above as shown in Figures 4 and 5, followed by washing with water only to determine the degree of stain removal and the surface Observed changes. The contaminants used in the test were the same as those in the antifouling test described above, including chili oil in the upper left part A2 of the textile product 1 shown in Figure 6, ballpoint pen ink in the upper right part B2, and red wine in the lower left part C2. , sauce was attached to the lower right part D2.

As shown in FIG. 6, it was confirmed that the test fabric had sufficient stain resistance even in the stain resistance test after the Taber abrasion test. In other words, it was confirmed that most of the dirt had been removed from the chili oil in Part A2 and the sauce in Part D2, and the ballpoint pen in Part B2 and the red wine in Part C2 were only lightly colored, and were excellent. The stain resistance was confirmed.

FIG. 7 is a photograph showing the results of an antifouling test on a textile product according to a comparative example. The comparative test fabric used in the test was Anelka. The warp yarns are Taslan yarns with a thickness of 400 denier, and the number of warps is 32 warps/inch. The wefts are Taslan yarn with a thickness of 400 denier, and the number of threads is 16 per inch, and a 1/4.5 count malle yarn with a thickness of 16 threads per inch.

Regarding the test fabric of the comparative example, the steps corresponding to the SR processing step S5 (see FIG. 2) and the weak water repellent processing step S7 (see FIG. 2) of the manufacturing method according to the embodiment of the present invention were not performed. That is, the test fabric of the comparative example did not have a structure corresponding to the polyester resin 3 (see FIG. 1) and the fluororesin 4 (see FIG. 1) of the textile product 1 according to the embodiment of the present invention.

In the antifouling test of the comparative example, the same contaminants as in the antifouling test of the example of the present invention were attached to the test fabric. That is, on the test dough of the comparative example shown in FIG. 7, chili oil was applied to the upper left part A3, ballpoint pen ink was applied to the upper right part B3, red wine was applied to the lower left part C3, and sauce was applied to the lower right part D3. Thereafter, the test fabric was washed with water only under the same conditions as in the antifouling test of the embodiment of the present invention, and the degree of stain removal and surface changes of the test fabric were observed.

As shown in FIG. 7, it has been confirmed that the test fabric of the comparative example does not remove stains well. Specifically, although most of the dirt was removed from the sauce in Part D3, the thinned dirt remained visible in the chili oil in Part A3 and the red wine in Part C3. Regarding the ballpoint pen in section B3, the dirt was clearly visible and it was determined that it had not come off.

Thus, the test fabric of the textile product of the comparative example has low stain resistance. It was confirmed that the textile product 1 according to the example of the present invention has excellent stain resistance compared to the conventional technology.

Although not shown, similar tests were conducted on a plurality of other test fabrics, and it was confirmed that the textile product 1 had excellent stain resistance, texture, and durability.

Note that the present invention is not limited to the above-described embodiments, and various other modifications can be made without departing from the gist of the present invention.
