Abstract

PROBLEM TO BE SOLVED: To provide a fiber product with an activated carbon stably and durably attached thereto so as not to damage the feeling, high-degree absorption ability, or the like. SOLUTION: This fiber product with the activated carbon is obtained by attaching a suspension of the activated carbon having <=5 μm particle diameter to a fiber for spinning, and spinning the resultant fiber to provide the objective fiber product. When the activated carbon usable therefor is a carbonized product of the residue of a pinecone, a more high-grade product can be produced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber product to which activated carbon is adhered without impairing its function and a method for producing the same.

[0002]

2. Description of the Related Art Activated carbon has a deodorizing and adsorbing effect, as is well known, and can be expected to have a far-infrared ray effect and an antistatic effect. Various attempts have been made to make the environment and body comfortable.

[0003] As a means of obtaining a fiber product with the activated carbon, a method of sandwiching an activated carbon powder layer between two nonwoven fabrics or the like, a method of providing a mini-pocket for air-permeable activated carbon, or a method of providing a certain binder And a method of applying, impregnating, and adhering activated carbon using the above method.

In such a conventional method, the texture of a textile product is generally significantly impaired, and there is a fear that activated carbon may deviate during use or during washing or the like to stain the surrounding area black. If the binder is used with a high concentration to prevent this, the cured film naturally covers the surface of the activated carbon particles and blocks air, so that the essential adsorption and deodorization effects cannot be exerted. Therefore, the application range of the fiber product with activated carbon has to be extremely limited.

Activated carbon made of pine nut shell charcoal invented and developed by the present inventor has a very unique and excellent adsorption function because its fine structure is a honeycomb-like bag structure. As it turned out, it was desired to apply it to wider textiles.

[0005] Under the circumstances, the present invention provides a textile product that can exhibit the function of activated carbon without impairing the feeling and fashion by adhering activated carbon to textile products in a durable manner without using a dense binder. The task is to

[0006]

Means for Solving the Problems Activated carbon is made into ultrafine particles having a particle size of 5 μm or less, and a suspension thereof is adhered to fine fibers for spinning. ,cloth,
Various textile products such as clothes.

[0007] The activated carbon having a particle size of 5 µm or less can be used for ordinary 10 carbons.
Or slightly smaller than that of 30μ,
It can be manufactured with the current pulverization technology. If this is added to a liquid such as water and agitated, it easily becomes a suspension and becomes a colloid. If necessary, a small amount of a binder (binder, adhesive) may be mixed with the liquid.

[0008] (Fine) fibers for spinning include cotton, silk, wool, rayon, nylon, polyester, acrylic and the like.
Almost all of the commonly used ones are relevant. These are twisted and spun into yarns, or further bundled or woven to produce secondary products. At this time, it may be blended with ordinary fibers.

Particularly preferred as the activated carbon to be used is one obtained by carbonizing a pine nut shell (herein referred to as pineal charcoal). The present inventor has already obtained various patents and the like for this pineal charcoal, but the present invention is extremely effective in actually realizing the advantages thereof.

Needless to say, carbides such as fruit seeds and seed husks of other nuts also apply. The point is that the particle size of the carbon particles is 5 μm or less, and if it exceeds this, the action and effect of the present invention are not exhibited regardless of the type of activated carbon.

[0011]

When the particle size of activated carbon is reduced to 5 .mu.m or less and dispersed in a liquid such as water as described above, it becomes a colloidal suspension by vigorous Brownian motion because it is an ultrafine particle. The object to be attached is a fine fiber from which the fiber is spun, and its surface area is relatively large and widely released to the outside. Therefore, when the suspension is applied or impregnated to the fiber for spinning, the activated carbon particles, which are extremely fine particles, collide with the surface of the fiber for spinning with Brownian motion, and a physical or electrochemical adhesive force acts thereon. It is believed that this allows for a dye-like coating that does not readily exfoliate.

In fact, depending on the type of fiber, such as cotton, etc., it was possible to realize a solid adhesion that could withstand washing with water. However, this was made stronger, and non-woven fabric such as nylon was used. Even in the case of a polar material fiber, if a small amount of bonding or an adhesive (binder) is added to make it suitable for practical use, it shows extremely good adhesion even though the amount is very small. Met.

Therefore, even if a binder is present, a very small amount is sufficient, so that the surface of the activated carbon particles is not shut off from the outside air, the adsorption function can be sufficiently exhibited, and the fiber provided by the cured binder can be obtained. Since the stiffness hardly occurs, the texture of the finished textile product is so good that it does not seem to have activated carbon.

By the way, when activated carbon is adhered to the filament as described above, the particle size is 10 μm or 3 μm as in the prior art.
Activated carbon having a size of 0 μm or more was impossible.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION For example, a plant such as a fruit seed which is treated as waste is carbonized, and this is further reduced to a particle size of 5 μm or less. Then, the mixture is stirred and dispersed, adhered to and impregnated in nylon fibrils for spinning, and then twisted and spun.
These yarns are directly or further bundled to produce a fishing net or rope. These fishing nets and ropes prevent the attachment of marine plankton and fish and shellfish without using chemicals, are harmless to humans and animals, and prevent marine pollution.

Similarly, the above-mentioned pine coal is finely divided into particles having a particle diameter of 5 μm or less, and is similarly made into a suspension and spun while impregnating various fibers. When the obtained thread was stretched in water for hydroponics such as hyacinth, the growth was promoted, and the colors of flowers and leaves became more vivid. Did not.

Further, the texture of the cloth woven with the above-described pineal charcoal-yarn is comparable to that of a normal one, and has an extremely high deodorizing / adsorbing function and its persistence. It provided great comfort for the wearer.
In addition, the application range is extremely wide, and it goes without saying that it is not limited to the above example.

[0018]

As described above, according to the present invention, activated carbon having a high adsorption function and the like can be stably and durably adhered without impairing the texture such as softness, elongation, and shrinkage required for textile products. Fiber products can be obtained. In particular, when pineal charcoal is used, in addition to its unique deodorizing action, opportunities to exhibit excellent far-infrared ray action, humidity control action, ionic effect, antibacterial action, discharge effect, etc. are greatly expanded, It has an extremely wide range of effects on health and the environment.
