Description

  The present invention relates to a cleaner suitable for tableware, bathroom, body washing, and the like.

  Conventionally, a cleaner is a polyurethane foam alone, or a polyurethane foam and a bulky nonwoven fabric bonded together and punched or cut into a size that is easy to hold. However, this type of cleaner has a problem that the polyurethane foam alone has no dirt removal performance. Also, with the type bonded to the non-woven fabric, it is hard to wash dishes that are tightly rounded, such as cups and glasses, and the bulky non-woven fabric peels off during use or fluffs and is not durable. There was a problem.

  Therefore, in order to make it easier to wash dishes such as cups and glasses that have been rounded, cleaners have been developed in which polyurethane foam is covered with a cloth without being bonded to a bulky nonwoven fabric. However, in any case, since a soft polyurethane foam that easily contains water is used, drainage and drainage after washing are poor, and if left for a while, it becomes easy for bacteria to propagate and discoloration. Furthermore, there was a problem that the polyurethane foam itself was easily distorted during use and the durability was poor.

  Accordingly, there is known a cleaner (see Patent Document 1) that does not use polyurethane foam but has improved water drainage and air resistance by, for example, a scouring method in which mesh layers of two layers of front and back are laminated. However, this type of cleaner has a problem that the opening portion of the mesh is as large as 4 mm, and dust adheres or enters the inside, which is not hygienic.

On the other hand, Patent Document 2 or Patent Document 3 describes a cloth or a cleaning tool that has improved drainage and durability by using a knitted fabric in which front and back ground structures are connected with a connecting thread without sewing or bonding. Is described.
Japanese Utility Model Publication No. 4-21359 Japanese Patent Laid-Open No. 5-148736 JP 2002-61056 A Japanese Patent Laid-Open No. 08-10468

  However, in the cloth or the cleaning tool described in Patent Document 2 or 3, the end portion (peripheral portion, periphery) of the fabric is not processed, and the connecting yarn protruding from the end portion is an obstacle during cleaning. It was difficult to use. In addition, the connecting yarns connecting the knitted fabrics are crushed and the cushioning properties are impaired, and the thickness is reduced during use because they are easily distorted. Furthermore, since the opening part is enlarged to improve the water drainage property, dust enters the fabric from the opening part, and fine dirt adheres to the connecting thread part, which tends to be unsanitary, There was also a problem that the foam could not be used as a cleaner as it had a foam and poor foaming.

  On the other hand, Patent Document 4 describes a cushion structure having a three-dimensional multiple structure. However, the cushion structure described in Patent Document 4 has a problem that dust is easily collected on the surface of the cleaner because the unevenness is too large.

  Therefore, the present invention aims to solve the above problems, and an object of the present invention is to provide a cleaner that is excellent in drainage and drainage, has an appropriate thickness and cushioning property, is hardly distorted, and has excellent durability.

  The present inventor has devised a cleaner that achieves the object of the present invention as a result of diligent research in order to solve the above-described problems in the prior art.

The three-dimensional multiple woven fabric is characterized in that the end of the first woven fabric and the end of the second woven fabric are fixedly integrated.

  According to the present invention, since the first woven fabric and the second woven fabric include the three-dimensional multiple woven fabric connected to the space forming yarn, the space portion is formed between the first woven fabric and the second woven fabric. Is done. By this space portion, foaming which is a function necessary for the cleaner can be generated. Furthermore, since this space part is connected with the exterior via the 1st woven fabric and the 2nd woven fabric, drainage and drainage are good, and hygienic use is possible. Moreover, moderate thickness and cushioning properties can be obtained by the presence of this space portion. Furthermore, the cleaner is made by fixing and integrating the end of the first woven fabric and the end of the second woven fabric, making it easier to control thickness and hardness, improving usability, It is difficult to cause deformation even during use, and durability is increased. Further, since the end portion of the first woven fabric and the end portion of the second woven fabric are fixed and integrated, the space forming yarn protrudes from the end portions of the first woven fabric and the second woven fabric. This prevents the work from getting in the way and improves convenience. In addition, by selecting a fiber material or changing a pattern, the fabric can be controlled in terms of stiffness and softness according to the object to be cleaned, and can improve dirt removal performance.

  In particular, in the present invention, since it has a three-dimensional multiple woven fabric using a first woven fabric in which a large number of openings of 3.5 mm square or less are formed by a large number of weaves, it is excellent in drainage and drainage, and has an appropriate thickness and cushion. And is difficult to distort and can increase durability.

  Furthermore, when the space forming yarn contracts, the first woven fabric and the second woven fabric are swollen in a convex shape with respect to the space forming yarn to form a space portion between the first woven fabric and the second woven fabric. Is preferred.

  Furthermore, it is preferable that an intermediate void layer is formed between the first woven fabric and the second woven fabric. According to this cleaner, since the intermediate void layer portion is formed between the first woven fabric and the second woven fabric, the cleaner has an intermediate void layer portion between the first woven fabric and the second woven fabric. There are voids corresponding to the thickness. This void can cause foaming, which is a necessary function of the cleaner. Furthermore, since this intermediate space layer portion communicates with the outside through the first and second woven fabrics, drainage and drainage are good, and hygienic use is possible. Moreover, moderate thickness and cushioning properties can be obtained due to the presence of the intermediate void layer. In this intermediate void layer portion, it is possible to control the thickness, water drainage performance, cushioning properties, etc. by selecting a fiber material and changing the connection interval and connection method.

  Furthermore, it is preferable that the first woven fabric has an area ratio of the fiber covered area to the opening portion of 1: 0.1 to 1.5.

  Furthermore, it is preferable that a plurality of three-dimensional multi-woven fabrics are provided, and a plurality of layers are formed of the plurality of three-dimensional multi-woven fabrics so that the first woven fabric is arranged on the surface layer. It becomes easier to control thickness and cushioning properties, improves usability, makes it difficult to cause deformation even during long-term use, and increases durability.

  Furthermore, it is preferable that a single three-dimensional multi-woven fabric is provided and a single layer is formed by the three-dimensional multi-woven fabric.

  Furthermore, it is preferable that the first woven fabric is connected to the space forming yarn at an angle of 20 to 70 degrees.
