Summary of the Invention

Problems to be Solved by the Invention

[0004] The non-slip sheet provided with the non-slip member of the prior art has a structure in which the non-slip member is adhered to the surface of the base material, so the non-slip member is easily peeled off from the base material by external forces such as friction during use and washing, and there is a problem in durability. In addition, the non-slip sheet formed by forming non-slip particles on raised fibers has a structure in which the non-slip particles are scattered on the raised fibers, so the contact area with the contacted object is limited, and there is room for improvement in the non-slip function. [Means for solving the problem]

[0005] The anti-slip sheet of this invention comprises a base material having an anti-slip surface and an anti-slip structure provided on the anti-slip surface, wherein the anti-slip structure is an adhesive layer formed by applying an adhesive to the anti-slip surface. The anti-slip sheet of this invention may contain a water-based acrylic adhesive. The anti-slip sheet of this invention may also contain a mite-repellent component in its adhesive. The anti-slip sheet of the present invention may have a base material made of nonwoven fabric, and the anti-slip structure may consist of a plurality of napped surfaces provided on the anti-slip surface, a friction layer formed by bonding the roots of the plurality of napped surfaces with an adhesive, and an adhesive layer continuous with the friction layer and formed by applying an adhesive to the surface of the tip of the plurality of napped surfaces. The anti-slip sheet of this invention may have a napped length that is within the range of 0.1 to 5 mm. The anti-slip sheet of this invention may have a base material that is a needle-punched nonwoven fabric reinforced with needle punching. The anti-slip sheet of this invention may have anti-slip surfaces on both sides. [Effects of the Invention]

[0006] The anti-slip sheet of this invention has an anti-slip structure that is bonded to the base material by the application of an adhesive, so the anti-slip structure is less likely to peel off even with repeated use such as friction and washing, and can exhibit excellent durability. Furthermore, a surface-like anti-slip structure, created by applying adhesive to the entire surface of the base material with a roller, can provide a high level of anti-slip functionality. [Brief explanation of the drawing]

[0007] [Figure 1] Instructions for use with anti-slip sheets [Figure 2] Conceptual diagram of an anti-slip structure [Figure 3] Conceptual diagram of Example 2 [Modes for carrying out the invention]

[0008] The anti-slip sheet of this invention will be described in detail below with reference to the drawings. [Examples]

[0009] <1> Anti-slip sheet Anti-slip sheet 1 is a sheet that provides an anti-slip function to the installation surface. The anti-slip sheet 1 can be used as an outer sheet for various products such as mattresses, carpets, cushions, pillowcases, and quilted pads, with the anti-slip surface 11 facing outwards. In addition, the anti-slip sheet 1 may be used on its own. The anti-slip sheet 1 comprises at least a base material 10 having an anti-slip surface 11, and an anti-slip structure 20 provided on the anti-slip surface 11 of the base material 10.

[0010] <2> Base material The base material 10 is a nonwoven fabric that constitutes the base of the anti-slip sheet 1. The base material 10 has at least one surface that is a non-slip surface 11. In this embodiment, a needle-punched nonwoven fabric is used as the base material 10, which is made by forming polypropylene short fibers into a mesh and reinforcing it with needle punching 1 to 3 times. Needle-punched nonwoven fabrics exhibit high tensile strength and abrasion resistance because the short fibers are tightly intertwined due to the needle punching reinforcement. However, the base material 10 is not limited to needle-punched nonwoven fabric, but may also be spunlace nonwoven fabric, chemical bonded nonwoven fabric, etc. Furthermore, the material of the nonwoven fabric is not limited to polypropylene, but can be polyethylene, polyester, nylon, natural fibers, etc. Furthermore, both sides of the base material 10 may be used as anti-slip surfaces 11.

[0011] <3> Anti-slip structure (Figure 2) The anti-slip structure 20 is a structure that provides the anti-slip function for the anti-slip surface 11. In this example, the anti-slip structure 20 consists of a combination of a friction layer 22 and an adhesive layer 23, which is configured by applying adhesive A to a plurality of naps 21 randomly arranged on the upper surface of the anti-slip surface 11. The friction layer 22 and the adhesive layer 23 are continuous via the adhesive A. The anti-slip structure 20 is formed by applying the adhesive A to one surface of the base material 10 with a roller, and drying and curing it in a predetermined temperature environment. The diameter and length of the naps 21 are not limited, but it is desirable that the extended length is within the range of 0.1 to 5 mm.

[0012] <3.1>Adhesive Adhesive A is a material constituting the anti-slip structure 20. In this example, a water-based acrylic adhesive is adopted as the adhesive A. However, the adhesive A is not limited to acrylic-based ones, and various other adhesives such as urethane-based, rubber-based, and silicone-based adhesives can be used. Further, in this example, the adhesive A contains a mite control component. Here, the term "mite control component" refers to a component having at least one of an insecticidal action, a repellent action, or a growth inhibitory action against mites. Specifically, as the mite control component, a pyrethroid compound, an organophosphorus compound, an amide compound, a natural essential oil component, or a combination thereof can be adopted. The blending amount of the mite control component can be appropriately selected according to the application, but for example, it is preferable that the mass ratio of the water-based acrylic adhesive to the mite control component is 97:3. This blending makes it possible to uniformly disperse and hold the mite control component in the adhesive A.

[0013] <3.2>Friction Layer The friction layer 22 is the base layer of the anti-slip structure 20. The friction layer 22 is formed by binding the root sides of the naps 21 with the adhesive A. The adhesive A applied to the naps 21 with a roller penetrates to the root sides of the naps 21, and binds the plurality of naps 21 to each other while they remain in a disordered state. As a result, the bundles of naps 21 form an integrated structure, which suppresses the naps from individually shifting or collapsing when in contact with a contacted object, thereby exhibiting a high frictional force.

[0014] <3.3> Adhesive layer The adhesive layer 23 is the surface layer of the anti-slip structure 20. The adhesive layer 23 is formed by applying adhesive A to the tip surface of the napped surface 21. The adhesive layer 23, through the cohesive properties of adhesive A, connects with the friction layer 22, providing high tackiness while remaining virtually non-adherent to the object being contacted. As a result, it leaves less stickiness on the object being contacted, providing a high level of comfort during use.

[0015] <4> Features of the anti-slip structure The anti-slip structure 20 of this embodiment can exhibit a high anti-slip function through a combination of a friction layer 22 (frictional action) that uses the napped surface 21 itself as an anti-slip structure by binding the napped surface 21 in a disordered state through a simple process of applying adhesive A to a nonwoven fabric base material 10 with a roller, and an adhesive layer 23 (adhesive action) that enhances the frictional force by utilizing the appropriate tackiness of the adhesive A. [Examples]

[0016] [Example where the base material is made of woven fabric or the like] (Figure 3) In Example 1, a nonwoven fabric was used as the base material 10, but this is not limited to that. In this embodiment, a woven fabric made of polyester fibers is used as the base material 10. In this embodiment, adhesive A is applied to the anti-slip surface 11 of the base material 10 using a roller. The adhesive A adheres to the fibers exposed on the anti-slip surface 11 and penetrates between the fibers, hardening as it does so. This forms an anti-slip structure 20 consisting of an adhesive layer 24 on the anti-slip surface 11. The woven fabric is made by plain weaving fibers, and multiple fibers are exposed on the surface in different directions, so the adhesive A is easily retained on the anti-slip surface 11, and the adhesive layer 24 is less likely to peel off even after curing. Furthermore, the material of the woven fabric is not limited to polyester fibers, but may also be polyethylene fibers, polypropylene fibers, polyurethane fibers, etc. Also, the base material 10 is not limited to woven fabric, but may also be knitted fabric, resin sheet, foam sheet, etc. [Explanation of Symbols]
