(Field of Industrial Application) The present invention relates to a rod-shaped absorbent material for the oral cavity that is used in dental treatment to absorb and remove unnecessary moisture such as saliva in the oral cavity. (Conventional technology) Conventionally, in dental treatment, etc., it has been used to absorb and remove moisture such as saliva in the oral cavity, to secure space for treatment, etc.
Furthermore, when interlocking, etc., absorbent cotton, which is an aggregate of short fibers, is cut into appropriate sizes or rolled. Cut cotton and cotton that has been processed into rods are also used. (Problems to be Solved by the Invention) However, in the conventional method described above, in the case of absorbent cotton, it is necessary to cut it into an appropriate size or roll it up each time it is used, as described above.
In addition, although Katsuto cotton performs well for cleaning the oral cavity, it has a lot of fuzz and leaves a lot of fibers in the oral cavity, and in the case of cotton rods, it is not improved compared to Katsuto cotton and absorbent cotton. Adhesives such as carboxymethyl cellulose, which are used to prevent fuzz on the surface of objects and provide shape retention, are water-soluble, so they are eluted by saliva, etc., and as a result, fibers may remain in the oral cavity or be used in therapeutic tools. Get entangled in something. In order to prevent these fibers from falling off, the outer periphery is wrapped with a tape-like nonwoven fabric (patent application 1983-
138367) and has been improved to a considerable extent. A further improvement to this would be to mix a superabsorbent substance inside the rod-shaped body, but there is a problem in that the superabsorbent substance swells when it absorbs water and oozes out from the open surfaces at both ends. The present invention aims to improve these problems, and provides a rod-shaped absorbent material for the oral cavity that has high water absorption capacity, good exclusion effect, and does not ooze out superabsorbent substances. (Means for Solving the Problems) The present invention consists of a rod-like body A of a fiber aggregate and a rod-like body B containing a superabsorbent substance, and the rod-like bodies A are arranged at both ends of the rod-like body B, and This is a rod-shaped absorbent material for oral cavity that has a water-permeable tape wrapped around its outer periphery. The rod-shaped body A can be formed by any method as long as the fiber aggregate is formed into a rod shape, but it can be made of crimped length fibers with good water absorption properties, such as acetate fibers, polypropylene fibers, polyester fibers, acrylic fibers, rayon, etc. Single fibers or a mixture of fibers are uniformly opened and bundled, wrapped with water-permeable tape and formed into a rod-shaped body, short fiber slivers such as absorbent cotton are opened and bundled, and wrapped with water-permeable tape. short fiber slivers, such as absorbent cotton, are opened and converged to form a rod, and are given shape retention properties with carboxymethyl cellulose, etc., and pulp fibers are bonded together using an adhesive. It can be made into a sheet, then converged, wrapped with water-permeable tape, and shaped into a rod. In addition, rod-shaped body B containing a super absorbent substance
After uniformly opening crimped long fibers such as acetate fibers, polypropylene fibers, polyester fibers, acrylic fibers, and rayon fibers, or a mixture thereof, powder or fibers of highly water-absorbing substances are added, and the fibers are shaped into rods using water-permeable tape. A rod-shaped rod-shaped object can be used, such as one wrapped around the body or a rod-shaped object made by wrapping a mixture of crushed pulp and super-absorbent substance powder with water-permeable tape. A rod-shaped body A is placed on each side of this rod-shaped body B, and a water-permeable tape is wound around the entire outer periphery of the rod-shaped body at least approximately once, and at least the overlapping portion of this tape is bonded by gluing, fusing, etc. with a glue or the like. By doing so, the oral cavity rod-shaped absorbent material of the present invention is obtained. As the water-permeable tape, tapes such as sheet-like tapes made by mixing nonwoven fabrics such as rayon, polyester fibers, and polypropylene fibers, and short fibers such as rayon, polyester fibers, and polypropylene fibers with pulp fibers can be used. However, for suitability for use in the oral cavity, it is necessary to have a width of 15 mm and a tensile strength of 45 g or more. Further, in order to wrap and join the water-permeable tape around the entire rod-like body in which the rod-like body A and the rod-like body B are arranged, it is preferable to use a water-insoluble adhesive as the adhesive because it can withstand long-term use. Bonding may be performed not only at the overlapped portion of the tapes but also at the entire or part of the contact portion between the outer peripheral surface of the entire rod-shaped body and the tape, and in such a case, the superabsorbent material may swell due to water absorption. It can withstand the swelling force sometimes and has good shape retention. In addition, for water-permeable tapes that use heat-fusible fibers made of low melting point components such as polyester, polypropylene, polyethylene, etc. alone or in combination, the tape overlaps the joints and the entire rod-shaped body is arranged. The outer circumferential surface of the tape and the tape contact portion can be simultaneously joined by fusion bonding. (Function) In the present invention, a rod-like body A that does not contain a highly water-absorbent substance is arranged at both ends of a rod-like body B that contains a highly water-absorbent substance, and the rod-like body A that does not contain a highly water-absorbent substance is wrapped together with a water-permeable tape that has excellent wet strength. This makes it possible to provide a rod-shaped absorbent material for the oral cavity that has a high water absorption capacity, has an excellent exclusion effect without causing the constituent fibers to fall off, and does not ooze out a highly water-absorbing substance. (Example) The present invention will be explained below with reference to Examples. Example: After uniformly opening an acetate crimped long fiber tow with a single fiber fineness of 3 denier and a total fineness of 50,000 denier using normal cigarette filter manufacturing equipment, the paper is made from hemp and rayon short fibers while converging.
A 12 g/m 2 tea bag paper is wrapped in a 32 mm wide tape, and the overlapping parts of the tape are bonded with ethylene/vinyl acetate copolymer hot melt glue to create a product with a diameter of 9.7 mm, length of 84 mm, and weight of 0.637 g. / book rod-shaped body A 1 was made. Next, a vibrating powder feeder was attached to the cigarette filter manufacturing equipment, and after opening the acetate crimped long fiber tow in the same manner as above, 150~250μ, water absorption capacity (relative to own weight)
Add 500 to 700 times more white granular super absorbent powder,
Similarly, paper tape for teabags is 9.7mm in diameter.
A rod-shaped body B1 having a length of 120 mm and a weight of 0.996 g/piece was manufactured. Here, the ratio of the weight of the superabsorbent powder to the acetate crimped long fiber tow was 126%. Next, the rod-shaped body A 1 and the rod-shaped body B 1 are each cut into 1/6 pieces, the cut pieces are arranged alternately, and the outer circumference is 30 g/m in basis weight as shown in Japanese Patent Publication No. 48-4590 etc. 2 , width
Wrapped with rayon non-woven tape of 32 mm, wet tensile strength 180 g/15 mm width, the overlapping portions of this non-woven tape were joined with ethylene/vinyl acetate copolymer hot melt glue as described above, and the non-woven tape, rod-shaped body A, and rod-shaped body The array of B is fixed with the above-mentioned hot melt glue and made into a continuous rod-shaped body, and by cutting the rod-shaped body A 1 at the center, the rod-shaped body A with a length of 7 mm becomes the rod-shaped body B with a length of 20 mm. A rod-shaped absorbent material having a weight of 0.307 g/piece as shown in FIG. 1 was obtained, which was placed on both sides. As Comparative Example 1, a material shown in Japanese Patent Application No. 138367/1983 was made using the same long fiber aggregate and nonwoven tape as in the above example, with a diameter of 9.7 mm and a length of 30 mm.
The absorbent material weighing 0.223 g/piece was comparatively measured, and as Comparative Example 2, commercially available roll cotton with a diameter of 8.6 mm, length 30 mm, and weight 0.228 g/piece was compared, and the results were compared to the absorbent material obtained in the example. The results are shown in Table 1 along with the physical results. In the water absorption test, the sample was placed horizontally in a shear dish filled with water so that half of its diameter was immersed in water for 5 minutes, and the weight before and after water absorption was compared. In addition, when measuring hardness before water absorption, place the sample horizontally.
The hardness after water absorption is expressed as the value obtained by dividing the height from the bottom surface when a 300g load is applied from above by the height from the bottom surface before applying the load, and multiplying the value by 100. The value is calculated by dividing the height from the bottom surface when the sample is placed horizontally and applying a load of 300 g by the height from the bottom surface of the sample before water absorption is applied, multiplied by 100. Moreover, the water absorption capacity indicates the value obtained by dividing the weight after water absorption by the weight before water absorption.
