Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heat-retaining cloth that emits far-infrared rays and a heat-retaining supporter.

[Conventional technology]

It has been well known that ceramics such as alumina, zirconia, and magnesia emit far-infrared rays.

In addition, far-infrared rays have a heat-retaining effect when applied to the human body, promote blood circulation, and maintain health, and are used for medical purposes, particularly in the treatment of sprains and the like.

However, emitting far-infrared rays requires large equipment such as a far-infrared generator, and the time for receiving far-infrared rays is limited, so g! It also has the disadvantage of limited health maintenance or therapeutic efficacy.

On the other hand, in order to provide clothing with a heat-retaining effect, a heat-retaining cloth containing fine particles that emit far-infrared rays has been proposed in JP-A-63-227828.

However, this heat-retaining cloth has no elasticity and is not suitable for use as a supporter fixed to a necessary part of the body.

[Problems to be Solved by the Invention] The present invention provides elastic cloth, which has strength to withstand tension when used as a supporter and is fastened with a hook-and-loop fastener, and also has excellent heat retention effect. The object of the present invention is to provide a supporter made of cloth.

[Means to solve the problem]

As a result of intensive research, the present inventors have discovered a method for solving the problem of the filament containing inorganic powder easily breaking when stretched or contracted when using yarn containing far-infrared emitting inorganic powder in elastic cloth. The elastic fabric has a loop-shaped pile yarn on one side, and by incorporating an inorganic powder with far-infrared radiation only in the pile yarn, which is hardly under tension during use, the fabric has strength and efficient heat retention. The inventors have discovered that this effect can be achieved and have developed the present invention.

That is, the present invention provides a cloth containing 0.05 to 5% by weight of fine particles having far-infrared radiation, the cloth having a loop-shaped pile on one side of a woven cloth consisting of warp and weft of elastic fiber yarns. The object of the present invention is to provide a heat-retaining cloth and a supporter made of the heat-retaining cloth, which has a structure in which yarns are provided, and the looped pile yarn contains fine particles having far-infrared radiation.

The ceramic fine particles having far-infrared radiation used in the present invention include inorganic substances that emit far-infrared rays with a wavelength of 4 μm or more, particularly 7 to 18 μm, at temperatures in the body temperature range, such as barium sulfate, silica, titanium oxide (titania).
, zircon oxide (zir?nia), manganese dioxide, ferric oxide, cobalt oxide, cupric oxide, titania-alumina ceramics, cordierite, β-spodumene, alumina, aluminum titanate, silica, alumina Silica equivalent mixed ceramic and manganese dioxide 60
% - 20% ferric oxide - 10% cupric oxide - 10% cobaltous oxide - ceramic sintered fine particles of a composition can be suitably used. In particular, the final sintered body composition powder particles are desirable in that they emit far-infrared radiation close to that of a black body.

The smaller the particle size of the inorganic powder used in the present invention is, the easier the spinning operation becomes, and the far-infrared radiation area increases, so it is synergistically desirable.
It is desirable to use a fine powder having a particle size of 1/#m or less, more preferably 0.5 μm or less.

The present invention will be explained in more detail with reference to drawings of embodiments.

The loop-shaped pile yarn having far-infrared radiation, which is a feature of the present invention, is knitted into the stitches of the cloth in a loop shape as shown in the enlarged plan view of FIG. 1, and is made of synthetic fiber material, For example, the above-mentioned far-infrared emitting inorganic fine particles are added to polyester, nylon, polypropylene, etc.
．． A blend of about 5 to 30% and melt spinning can be used.

From the point of view of texture, texture, and heat retention effect, the synthetic fiber filament containing inorganic powder is compared with cotton and other fibers with a 40 to 70%
It is desirable that the pile yarn used in the present invention be produced by blending yarn with %.

Furthermore, for the above-mentioned synthetic fiber filaments containing inorganic powder that are used either as a blend with cotton or used alone, it is better to first spin synthetic fiber filaments containing a large amount of inorganic powder and then blend this with pure synthetic fibers that do not contain inorganic powder. , fibers with high tensile strength can be obtained at the same inorganic content.

In this case, inorganic powder-containing synthetic fiber 100 to 20
From 0 to 80% by weight of pure synthetic fibers can be used.

These yarn spinning operations can be performed by known means.

In the pile yarn used in the present invention, it is possible to use the above-mentioned single synthetic fiber yarn containing a far-infrared radioactive substance and a composite yarn of this and a fiber that does not contain inorganic substances, but in either case, the total weight of the pile yarn is The far-infrared emitting fine particles can be contained in an amount of 0.5 to 30% by weight, preferably 1 to 15% by weight.

The thermal fabric of the present invention has a structure in which warp yarns 11, 12, and 13, which are also elastic fiber yarns, are knitted with weft yarns 1, 2.3, which are elastic fiber yarns, as shown in the enlarged view of the cloth plane in FIG. Each of the warp yarns has an elastic fiber 5, for example, a synthetic rubber fiber of about 20 denier such as spandex, as a core fiber, and a normal synthetic or natural inelastic fiber 6 of 70 denier, such as nylon, It is made by spinning a mixture of polyester and the like, and when it contracts, that is, in its normal state, it has a structure in which inelastic fibers are spirally wound around elastic fibers, as shown in Figure 1. The inelastic fibers 6 exhibit tensile strength when the elastic fibers 5 are stretched beyond a certain level, contributing to the strength of the cloth.

The elastic fiber used in the present invention can be used without any particular restriction as long as it is a spinnable elastic material, and usually a block copolymer of rubbery chains and fibrous chains can be used.

As such a composite elastic yarn, commercially available Operon manufactured by DuPont, Daslin manufactured by Toyobo, etc. can be used.

In the embodiment of the present invention shown in FIG. 1, the elastic fiber yarns of the weft yarns 7 are not composite elastic yarns like the warp yarns but are simply elastic fiber yarns. As such a single elastic thread,
Stretchable synthetic fibers with higher tensile strength than rubber fibers, such as
From the viewpoint of strength, it is desirable to use woolly nylon thread of about 70 denier alone.

The elastic fiber threads forming the skeleton of the heat-retaining fabric of the present invention may be made of elastic fibers alone or mixed with inelastic fibers. The latter has a greater degree of expansion and contraction.

In the present invention, both the warp and the weft can be in the former or the latter form depending on the degree of stretch required depending on the place of use, or the warp and weft can be different as shown in the drawings. can.

By expanding and contracting both the warp and weft threads of the insulating fabric of the present invention, the entire cloth can freely expand and contract in all directions, allowing it to adhere to any curved surface of the body.

As shown in FIG. 1, the loop-shaped pile yarn 4 used in the present invention is provided in a loop shape in the stitches of the weft and warp yarns. Moreover, it is only provided on one side of the cloth.

In the present invention, it is possible to provide pile yarns that emit far-infrared rays on both sides, but with pile yarns attached to the back side, the far-infrared rays are blocked by the fabric body, making it inefficient. This has the advantage that it can be used even if it is turned over.

The pile yarn of the present invention can be knitted according to a conventional method for manufacturing terry cloth.

In the thermal fabric of the present invention, inorganic fine particles having far-infrared radiation are used in an amount of 0.05 to 5% by weight, preferably 0.1 to 3% by weight, based on the weight of the material.

If the content is low, the effect will be small, and if the content is high, manufacturing processes such as spinning, weaving, and sewing will become difficult.

Further, it is desirable to use the far-infrared emissive pile yarn in an amount of 5 to 40% by weight, preferably 15 to 30% by weight, based on the total weight of the fabric.

As shown in Fig. 1, the fif and warm cloth of the present invention has a structure in which pile yarns are added that do not affect the tension of the warp and weft yarns that support expansion/contraction and tensile strength at all, and inorganic powder that has far-infrared radiation only in the pile yarns. Because it is a mixture of
Fabric can be given far-infrared radiation function.

The heat insulating fabric of the present invention can be sewn and used as a supporter.

The supporter of the present invention can be fixed to any person with appropriate firmness by attaching the hook-and-loop fastener at an appropriate position and adjusting the fixing position of the hook-and-loop fastener.

In addition to improving the heat retention properties of the surface where the pile threads are implanted, the heat retention effect is further improved by the far infrared rays from the powder that emits far infrared rays.

This can be used as a support for all parts of the body, such as knees, elbows, arms, shoulders, ankles, wrists, hips, chest, and abdomen. Since this supporter is fixed to the affected area etc. by the elasticity of the cloth, the peripheral part of the supporter comes into close contact with the human body. Therefore, the heat retention effect is further improved synergistically.

Therefore, the supporter of the present invention can be used not only for treating sprains, muscle strains, rheumatism, etc., but also for simply keeping warm.

[Effects of the Invention] The heat-retaining cloth of the present invention is suitable for use as a supporter because of its elasticity, and is excellent for use in treatment, health care, and heat retention because it emits far-infrared rays.

Furthermore, the inclusion of inorganic powder has the advantage that elasticity and tensile strength do not deteriorate at all.

Furthermore, the sealing effect of elasticity works synergistically to keep you warm.
It has the remarkable advantage of being able to obtain very good heat retention effect, and is widely used.
