Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a cotton laminate for bedding with a molded surface and a cotton laminate for bedding equipped with a magnet, and more specifically to a material mainly for health bedding and bedding using magnets. The present invention relates to a method for manufacturing a cotton laminate suitable for use as a cotton 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 become clear 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 may distort the background 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 that also has rigidity, whereas in the latter case, it is relatively easy to attach a magnet that also has rigidity. The reality is that it is difficult to attach a rigid magnet because it is amorphous and too soft, and must be done manually.

On the other hand, the plastic core material is intended for spinal correction and acupressure effects due to its rigidity, but it is completely different from traditional cotton futons in terms of sleeping comfort, texture, and moisture absorption, so it feels strange. I can't forbid it. In order to compensate for the drawbacks of such plastic core materials, composite bedding made of these core materials and cotton 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 molded bedding characterized in that a cotton laminate having a resin layer arranged on the surface layer is heated to melting point, the resin layer on the surface layer is embossed into an arbitrary shape, and then cooled. The second aspect of the present invention is a method for manufacturing a cotton laminate for use in cotton, and the second aspect of the present invention is to heat and melt a cotton laminate with a resin layer disposed on the surface layer, press-form the resin layer in the surface layer into an arbitrary shape, and then cool it. , a method for producing a cotton laminate for bedding with magnets, which is characterized in that the mold of the embossed cotton laminate is filled and coated with an adhesive, and a magnet is inserted and bonded; Third, a cotton laminate with a resin layer on the surface layer is heated and melted, the resin layer on the surface layer is embossed into an arbitrary shape, cooled, and then glued into the mold of the embossed wire laminate. The method of manufacturing a cotton laminate for bedding with a magnet is characterized in that the material is filled and coated with a magnet, a magnet is inserted and bonded, and a cloth-like material is attached to the surface of the material.

The present invention will be explained based on drawings showing embodiments.

The resin used for the resin layer 1a is a thermoplastic resin, such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, ethylene-vinyl acetate copolymer, etc., and can be powder coated, latex coated, or dispersed in water or a solvent. Alternatively, a method may be exemplified in which cotton is impregnated with a resin by dipping or spraying a dissolved suspension or solution, and then dried. Embossing molding device 2
is an endless belt 4 formed by protruding embossed convex portions 3.
and at least one roll 5 provided above it, and further provided with heating means (not shown). A mold release agent such as a fluorine-based resin is applied to the surface of the endless belt 4 that comes into contact with the cotton laminate.
The inside of the device 2 is heated above the melting point of the low melting point line 1a, and the raw cotton laminate 1 introduced into the device
is introduced between the endless belt 4 and the roll 5, and the resin layer 1a is compression molded in a molten state. The embossed cotton laminate 6 is taken out from the device 2 and cooled by the cooling device 7, and the molten resin layer 1a is solidified in the molded state. In this case, a method of heating the endless belt 4 with a heater or the like is also a preferred embodiment.

In FIG. 2, raw cotton 1 having a resin layer disposed on its surface layer is introduced into an embossing molding device 2, and the surface layer is heated and melted to be embossing-molded. Embossing molding device 2
The embossed cotton laminate 6 that has come out is cooled by a cooling device 7 and stored in an appropriate length by a stepped roll 8. The cotton laminate 6 that has descended from the step roll 8
is intermittently guided to an adhesive filling device 9, and after the adhesive is filled and coated into the concave mold, it is guided to a magnet charging device 10, where the magnet is charged into the concave mold, and the adhesive is bonded. Fixed. If necessary, it is dried in a drying step, further cooled to room temperature in a cooling step, and cut into a predetermined length. Note that the cutting may be performed after the cooling device 7 and the subsequent steps may be carried out discontinuously, and in this case, the step roll 8 step is not necessary.

FIG. 3 is an enlarged view of the embossing forming device 2 shown in FIG. 2, which includes an endless belt 4 having a protruding embossing convex portion 3 and at least one roll 5 provided above the endless belt 4. Further, a heating means (not shown) is provided. A release agent is applied to the surface of the endless belt 4 that comes into contact with the cotton laminate. The inside of the device 2 is heated above the melting point of the resin layer 1a, and the raw cotton laminate 1 having the resin layer 1a on the surface introduced into the device is introduced between the endless belt 4 and the roll 5. , the resin layer 1a is compression molded in a molten state. The embossed cotton laminate 6 is taken out from the device 2 and cooled by the cooling device 7. In this example as well, the endless belt 4 may be heated with a heater.

FIG. 4 is an enlarged view of the main parts of the connecting agent filling process.
In the figure, the adhesive filling device 9 is equipped with a plurality of nozzles 11 on the front surface, and a connecting agent introducing pipe 12 is provided on the back side, and is connected to a connecting agent storage tank and a compressor (not shown). The nozzle 11 is located almost directly above the concave mold 13 of the pressed cotton laminate 6, and the compressor is used to compress the concave mold 13.
A predetermined amount of connecting agent 14 is filled and coated inside.

Furthermore, wool, silk, feathers, etc. may be mixed in for the purpose of improving the texture and hygroscopicity. Further, when using a ceramic heater, a mold release agent is not necessarily required.

In the present invention, after the magnet is attached, it is desirable to further attach a cloth-like material to the surface of the magnet so that the magnet does not come off during use. The cloth material is preferably coarse in order not to interfere with the magnetic force of the magnet; for example, cheesecloth, net, coarse nonwoven fabric, etc. are suitable.

As mentioned above, according to the present invention, it is possible to mass-produce semi-automatically or fully automatically formed cotton laminates and cotton laminates with magnets, and costs can be greatly reduced. In addition, the cotton laminate with magnets obtained by the present invention has dramatically improved adhesion with magnets compared to conventional soft cotton, and furthermore, by attaching a cloth-like material, it completely prevents separation during use. It can be prevented. Furthermore, it has a suitable hardness even when used as bedding or in combination with a plastic core material, so it does not become too soft like conventional cotton, and does not impair the spinal correction or acupressure effect. , it is possible to provide bedding that has the excellent cushioning properties, feel, and moisture absorption properties inherent to cotton.
