Description

[Detailed description of the device]

[Industrial field of application] [0001] This invention has the functionality of dusters, puffs, bath mats, etc. made of pile fabrics in which pile yarns having a double woven structure are microfibers of natural fibers, recycled fibers and synthetic fibers. The present invention relates to improvement and improvement of bulkiness.

[Prior Art] Conventionally, a pile woven fabric having a double weave design has a pile yarn 1 laid over the upper and lower woven fabrics of a 12-knit weave composed of ground warp yarns 2 and ground weft yarns 3, and is woven at the center. Cut 1 to make 2 fabrics. Single-sided pile fabric made of 100% rayon made by passing flat rayon filaments with a cross section of 1:18 on the upper and lower layers of a double weave structure using short rayon fibers for ground warp and weft and cutting at the center The rayon duster made is highly hydrophilic and has a large number of minute spaces due to the pile fabric. It has excellent wiping and rinsing effects when used after being moistened with water. In particular, oil stains can be wiped off without using a detergent and the oil can be drained well by washing with water. When it is wet with water, the pile structure changes, and each rayon yarn is entangled with each other to create a lot of space, which makes it easier for dirt and oil to be taken in, and when rinsed after that, the rayon pile threads become fluffed and become dirty in water. Since oil is released into the water, it is extremely effective and prized for household kitchens and for cleaning and washing cars around the engine of a car. However, on the other hand, it is often used while it is wet and it is not dried. In the kitchen of the home, from May to September every year, a slimy condition (water rot) causes mold and stains. Give birth. The same is true when used during car washing. Since the car is left wet at 70 ° C, it quickly reaches a slimy state, produces a foul odor, and has the major drawback of causing mold. Is the current situation. Furthermore, the conventional products are somewhat lacking in handheld feeling, and there is a demand for increased volume. In addition, face washing puffs, body washing puffs, and bath mats made of rayon long fibers, silk, cotton, wool, nylon and polyester microfibers, and the like also have the same drawbacks. The current situation is that even if the drying is improved, the growth of mold will be early (short period of 1 to 2 months), and the occurrence of mold will be suppressed.

[Problems to be solved by the invention] The problem to be solved is that the rainy season of dusters, puffs and bath mats made of pile fabrics made of rayon, silk, cotton, wool, nylon and polyester microfibers. It is to eliminate the problems such as becoming slimy and the mold that is a drawback during summer use, and the thin hand feeling.

[Means for Solving the Problem] In the present invention, in a single-sided pile fabric having a double weave design (12-over design), the pile yarn 1 is a rayon filament having a flat cross section, and the ground yarns 2 and 3 are Mainly made by overlapping the back side of rayon pile fabric machined and finished using spun yarn of rayon short fibers, and adding anti-mold and antibacterial properties in the middle, while at the same time increasing the volume of the product. To improve. In the present invention, as a result of a detailed examination at the time of use in order to solve the above-mentioned defect obstacle, it was found that a foamed urethane sheet is most suitable as a material to be sandwiched in the middle, and this sheet has a mildew-proofing property. The purpose can be achieved by adding functions such as antibacterial and deodorant. That is, deodorant components extracted from plants (camellia, cypress, hiba) were included in cyclodextrin, impregnated in porous silica and dried in fine powder. Antibacterial agents such as phthalimide-based N-dichlorofluoromethylthiophthalimide and alkylamine derivatives, and antifungal agents such as methyl benzimidazole carbamic acid, 2- (4-thiazole) benzimidazole and butyl ester of paraoxybenzoic acid are porous silica, It is impregnated with zeolite, dried in a fine powder, and dispersed and contained in the raw material mixture for urethane foam, respectively, and then foamed to form urethane foam 4 having a deodorant, antibacterial and antifungal performance with a thickness of 2 m / m. The urethane sheet 4 is sandwiched between the rayon pile cloths, the side surfaces thereof are overlocked with the thread 6, and the central area of the overlapped cloth is sewn vertically and horizontally with the thread 5 so that the area thereof is made as small as possible. Configure. In addition, a deodorant substance in which plant extracts from flavonoids and catechins are included in cyclodextrin is impregnated into porous silica gel to form a fine powder. In addition, the above-mentioned antibacterial and antifungal agents are impregnated in fine powder of natural zeolite, and then fine powder is dried to obtain powder, which is uniformly impregnated in the urethane foam raw material mixture and foamed to eliminate deodorant and antibacterial deodorant. -A rayon duster characterized by being configured to be sandwiched between rayon pile fabrics as a urethane sheet 4 having antifungal performance. At the same time, the rayon pile cloth is used as the outer surface of the bath mat, and the urethane foam sheet 4 is sandwiched between the lining and the side, and the side surface is hand-hooked with the water-absorbing acrylic yarn 2/32. Also, the short pile length (2 to 3 m / m) of the double-woven high-density pile fabric (16 pieces over 34) using pile yarn 1 such as rayon filament, silk, cotton, wool, nylon and polyester microfiber. In the face-wash puff and body puff made of the fabric), the back side is overlaid, and the normal urethane home is sandwiched between two upper and lower deodorant / antibacterial / deodorant-containing natural Zeolite fine powder mixed polyurethane homes in the middle. It is configured to be put in and sutured.

[Operation] The present invention is capable of preventing the generation of a bad odor due to slimy skin which is a drawback of conventional products by using the above-mentioned means, which is a drawback of conventional products during rainy season and summer. No problem occurred, and no problem occurred even if it was left in a wet state for a long time. In particular, even if it is left in a car at 70 ° C in a wet condition, it no longer causes a problem like the conventional one. In addition, the handheld feeling when using it has tended to be thin and does not fit comfortably in the hand, but because it is a 2 m / m thick urethane home mixed with deodorant, mildewproof and antibacterial agents, it feels voluminous and should be used when wet. It fits perfectly in the hand and is extremely easy to use. In order to improve durability, the center of a 20cm x 30cm size duster is sewn, for example, in the length and width with thread 5, and its area is 1/4 of that of the unsewn one. It improved by 1.5 to 2 times, making it less likely to tear and at the same time becoming familiar with the hand. In addition, you can enjoy fashion-oriented with a pattern of hearts, diamonds, etc. with different colored threads in the center. Further, it is known that a pile woven fabric in which the pile yarn is silk has a very fast onset of mold. By using this silk pile fabric and sandwiching deodorant / antibacterial / deodorant urethane between the face-washing puff and body-washing puff, the generation of mold can be suppressed.

[Embodiment] FIG. 1 is an enlarged perspective view showing an embodiment of a rayon duster having antifungal and antibacterial properties according to the present invention. Using a double weaving machine with a double woven structure (over 12 knits), 21 reed feathers, the pile yarns are warped with 300d / 30F 1152 rayon filaments, and the rayon short fibers are 30/2 4900 filaments. The rayon short fiber 10/1 was used as the weft, and the weaving was performed under the conditions of a pile length of 9 m / m 2 and a shot density of 38 yarns. The pile fabric weight was 454 g / M. This fabric was dyed and the pile yarn was napped with steam to finish. A single-sided rayon pile fabric having a width of 135 cm was obtained. This finished woven fabric was cut into a size of 43 cm x 32 cm and halved to a layered fabric of 21.5 cm x 32 cm. In the middle of this, extract from natural plant of camellia and cypress was included in cyclodextrin for deodorization. 5% silica fine powder containing performance product, N-dichlorofluoromethylthiophthalimide antibacterial agent and methyl benzimidazole carbamate mildew proofing agent were impregnated into 5 μm of natural zeolite fine powder and dried to obtain fine powder. 1 0.5% by weight of urethane foam raw material mixture was uniformly impregnated and foamed, and a 2 m / m thick urethane foam sheet 4 with deodorant, antibacterial and deodorant properties was sandwiched, and this side was inserted. Overlock with thread 6 and sew the center part of the overlapped material with thread 5 lengthwise and widthwise to remove deodorant of 20 cm x 30 cm size. It was obtained rayon duster. When actually used, this product swelled slightly when soaked in water, and it fits comfortably in the hand and is extremely easy to use compared to the conventional product, with no slimy feel and no mold. Also, by placing 4 to 5 sheets side by side in the rear back of the car (upper part of the rear seats) in a dry state, the bad odor inside the car was reduced to about half.

[Advantages of the Invention] As described above, the present invention prevents the generation of a bad odor due to the slimy spills that occur during the rainy season and summer, and it can be used repeatedly by keeping it in a wet condition without drying. Occurrence can also be prevented. The texture is more voluminous than the conventional product, and it has a feeling of holding it and is easy to use because it fits nicely in the hand. Durability is improved by forming various patterns with the thread 5 in the central part and reducing the area, and you can enjoy fashion with the colored thread 5 and the stitching pattern. The result can be understood by evaluating the antifungal performance with respect to durability by washing. The results are as follows, and the wash resistance is excellent.
