Abstract

PROBLEM TO BE SOLVED: To obtain a material capable of more widely exhibiting improving action of functional mineral powder on organisms and the near environment while effectively using waste. SOLUTION: Functional mineral powder is mixed with a rigid plastic in a molten state, made into a monofilament and formed into a cottony state. Especially a recycled resin of waste PET bottles is used as the rigid plastic and silica gel powder is used as at least one of the functional mineral powder. Consequently, a mat-like cottony body of three-dimensional stitch structure having an extremely high porosity is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a functional floc having a function that has a favorable effect on living bodies and the environment.

[0002]

2. Description of the Related Art Recently, various functional materials have been attracting attention to make living bodies and environments more comfortable, and attempts have been made to use them in clothing, building materials and the like. Many functional materials such as activated carbon, silica gel, tourmaline, far-infrared ceramics, photocatalytic minerals, and so-called wave stones are known, and they can be used in containers, molded with binders, or coated with paint. do it,
I used it as a watch.

[0003] Also, various functional fibers have been developed for synthetic fibers, and many of them have been commercialized, from structural ones such as hollow fiber membranes to those composed of new materials or coated. I have.

[0004]

As described above, there are many functional materials, but at present, the properties of the functional materials are not always sufficiently exhibited in actual products. . For example, the thickness of the raw fiber that is the basis of synthetic fiber is less than a few denier, and since the material is softer than ordinary plastic, it is extremely difficult to mix functional mineral powder with it. However, even if they are mixed, the strength and texture of the fiber product are significantly impaired, and it is virtually impossible to finish the fiber product with practical use.

[0005] Accordingly, various mineral-based functional materials having excellent characteristics have not yet been sufficiently exhibited in their surroundings. Under the present circumstances, the present invention aims to provide a product in a form in which these mineral-based functional materials can sufficiently exhibit their properties in a familiar place, so as to be useful for improving the health of the living body and the environment. As an issue.

[0006]

In order to solve the above-mentioned problems, the above-mentioned functional mineral powder is mixed with a molten rigid plastic and formed into a floc.

[0007] The mineral powder mentioned here also includes carbon powder, and has a particle size as small as possible, not more than 20 µm, preferably 5 µm.
It is about μ.

[0008] The term "rigid plastic" as used herein means a molding resin material having a rigidity higher than that of ordinary synthetic fibers, and more specifically, a plastic material having a rigidity higher than that of polypropylene.

Means for forming a flocculent shape are not particularly limited. First, the mixed material is melted and discharged from a fine nozzle to form a monofilament, which is innumerably bent / pointed based on a nonwoven fabric manufacturing technique. A known technique such as bonding or a method similar to cotton candy can sufficiently cope.

It is to be noted that particularly preferred as the rigid plastic in the present invention is polyethylene terephthalate resin, which is a molding material for PET bottles. Therefore, the waste recycled resin is extremely desirable in terms of cost, environment and resources.

When the monofilament made of polyethylene terephthalate resin is bent and joined to each other at a point contact portion, its internal structure becomes a so-called three-dimensional network, and the internal porosity becomes extremely large due to the rigidity of the resin. Those that maintain a mat-like form are easily obtained. By the way, this mat has a bulk specific gravity of 0.01
Despite being extremely light in weight, it has a very good shape-retaining force and can be made into a long sheet, and its use is extremely diverse.

It has been found that when silica gel powder is used as one of the functional mineral powders to be mixed, the chargeability is significantly reduced, and the antistatic effect and the grounding action are greatly useful for improving the quality as a health-oriented product.

[0013]

As described above, a rigid plastic is used for the cotton filament constituting the present invention.
Even if a mineral powder is mixed therein, sufficient strength and shape retention can be maintained. Therefore, the obtained cotton has extremely large voids inside and keeps a highly air-permeable form stably, so that the functional mineral powder contained therein is exposed to the outside air through a very small interval to the filament outer wall. On the other hand, the function can be sufficiently exhibited.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION In the process of reclaiming waste PET bottles, silica gel powder having an average particle size of 20 μm and wave ore having an average particle size of 5 μm (about 81% silicon dioxide, about 10% aluminum oxide, about 3% potassium oxide, About 3% of sodium oxide, about 1% of iron oxide, about 1% of calcium oxide,
20% by weight of about 0.3% of magnesium oxide and titanium oxide, ore composed of other trace components. The pellets are extruded in a molten state from a 7 to 10 denier monofilament forming nozzle, and the bulk specific gravity is 0.01, the thickness is 15 mm, and the width is 1 by a predetermined flocculent mat forming machine.
It is formed into a long sheet wound cotton-like mat of 20 cm and length of 50 m.

[0015] The cotton-like mat is cut into pieces each having a length of about 1.8 m to provide a core material for a comforter. This core material reflects the far-infrared ray and negative ion emission performance of the wave ore as it is, and at the same time, the chargeability is JIS-L-10.
According to the half-life measurement method of No. 94, extremely good results were obtained in which the sample was left for 3 hours at 20 ° C. and 40% RH for 1 second or less, and the futon of the product was extremely popular due to its good usability and comfort. .

The appearance of a part of the mat is approximately as shown in FIG.

[0017]

As described above, according to the present invention, various functional mineral powders which are considered to improve the health of the living body and the familiar environment are dispersed and arranged by the internal voids of the cotton.
Its functions are fully demonstrated, its application range is greatly expanded, and it also leads to the effective use of waste such as plastic bottles, which not only contributes to health and comfort, but also to environmental beautification and resource saving. is there.
