Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a cotton laminate with a shaped surface and a cotton laminate with a magnet. The present invention relates to a method for manufacturing a laminate.

BACKGROUND OF THE INVENTION Since ancient times, bedding made of cotton has been loved because of its excellent texture, softness, and hygroscopicity. However, as scientific research is carried out in the field of bedding, it has been discovered that the softness that has traditionally been prized is not necessarily desirable from the standpoint of maintaining and promoting health, and that bedding that is too soft can actually distort the spine and be harmful. has been pointed out. Furthermore, since the surface is flat and soft, it is difficult to expect acupressure effects.

In recent years, various types of health bedding have been put into practical use, and many have been proposed that utilize magnets, which are said to have therapeutic, health maintenance and promotion effects. These can be roughly divided into two types: those in which magnets are attached to a plastic bedding core made of polyurethane or polyethylene foam, and those in which magnets are attached to traditional cotton bedding. However, in the former case, the core material has a fixed shape and a certain degree of rigidity, so it is relatively easy to attach a magnet with appropriate rigidity; The reality is that it is amorphous and too soft, and attaching a rigid magnet is accompanied by many difficulties and must be done manually.

On the other hand, the plastic core material is intended for spinal correction and iFE effect due to its rigidity, but it is completely different from traditional cotton futons in terms of sleeping comfort, texture, and even hygroscopicity, making it feel strange. I can't forbid it.

In order to compensate for the drawbacks of such plastic core materials, composite bedding with these core materials has also been proposed. However, in this case, if ordinary cotton is used, it is too soft and may reduce the intended spinal correction effect of the plastic core material, and as mentioned above, it is not easy to attach a magnet to ordinary cotton. .

In view of these circumstances, the present invention provides a cotton laminate that overcomes the drawback of cotton being too soft and has a molded surface capable of exerting an acupressure effect, and a method for manufacturing the cotton laminate in which a magnet is efficiently arranged on the cotton laminate. This is what we provide.

That is, the first aspect of the present invention is a method for producing a shaped cotton laminate, which comprises heating and melting a cotton laminate having a resin layer disposed on the surface layer, molding it into an arbitrary shape by molding, and then cooling it. According to the second aspect of the present invention, a cotton laminate having a resin layer disposed on the surface layer is heated and melted, molded into an arbitrary shape by embossment, cooled, and then an adhesive is placed in the mold of the embossed cotton laminate. The third aspect of the present invention is a method for manufacturing a cotton laminate with a magnet, which is characterized by filling and coating, charging and adhering a magnet, and further, the third aspect of the present invention is a method of manufacturing a cotton laminate with a magnet, which is characterized in that the cotton laminate has a resin layer on its surface layer and is heated and melted. After embossing the embossed cotton laminate into an arbitrary shape and cooling it, the inside of the mold of the embossed cotton laminate is filled with an adhesive and coated, and a maggut is inserted and bonded. Each content is a method for manufacturing a cotton laminate with a magnet, which is characterized by being attached.
