Description

DETAILED DESCRIPTION OF THE INVENTION (1) Object of the Invention <Industrial field of application> The present invention relates to an improvement of a cloth for wipes and wipes which has a longer antibacterial action and a large cloth for wipes and wipes.

<Prior Art> The mat part conventionally used for a cloth for wipes uses chemical fiber or vegetable fiber alone, or a mat made of a mixed-spun or mixed-woven material, but a ceramic with an antibacterial agent burned on. There was no mat using spun chemical fibers mixed with granules.

As a prior art related to the present invention, as an improved type of carpet, a velor-like carpet using multifilament crimped yarn as pile yarn is disclosed in Japanese Patent Publication No. 59-3.
No. 4815.

However, this is an object to prevent hair loss, and is only common to that of the present application only in that a pile yarn is used.

In addition, a brush made of a fiber in which inorganic fine particles are mixed with an aromatic polyamide is proposed in JP-A-63-99804,
This is simply to increase the abrasion resistance by the inorganic fine particles in the fiber and to enhance the brushing effect, and the only common point is that the inorganic substance is mixed in the fiber with the one of the present application. .

On the other hand, when viewed from the area of the material of the fiber, zeolite particles containing metal ions having a bactericidal action are mixed in the organic polymer to form a fibrous material, which is disclosed in JP-A-59-133235,
No. 62-195038, respectively.

The present invention is intended to be applied to a cloth for wipes which requires extremely harsh conditions by adopting a novel means (baking) capable of more effectively maintaining the bactericidal action of the present invention.

Incidentally, JP-A-63-250309 discloses an antibacterial agent of a clay mineral having a metal ion or a metal compound between scraps, which is an invention of the antibacterial agent itself, and is considerably different from that of the present application. It is just one of the distant background technologies.

<Problems to be solved by the present invention> A cloth for wipes is put under extremely harsh conditions of use due to its nature and is easily soiled. As a woven fabric for mats, attention was paid to the use of fibers mixed with ceramic particles impregnated with an antibacterial agent (Japanese Patent Laid-Open No. 59-133235, etc.) for woven fabrics for mats. It seemed that all these problems were solved by this.

However, not to mention the towel mat, it is extremely easy to get dirty due to its role, so especially for commercial use,
Even with this fiber, the impregnated antibacterial agent constantly exudes and loses its antibacterial properties rapidly because it is washed frequently and strongly, so that even this fiber is not satisfactory.

As a result of many years of research based on the above, the present invention intends to provide a cloth for wipes which effectively solves all the above problems.

(2) Constitution of Invention The present invention provides a cloth for wipes having the following structure in order to solve the above problems.

<Means for Solving the Problem> In order to secure the durability of a scrap of bactericidal effect, first, a known antibacterial agent capable of withstanding high temperatures is mixed and stirred with the ceramic firing material.

Next, the ceramic firing raw material mixed with the antibacterial agent is fired into ceramics. Due to the heat at this time, the antibacterial agent is burned on all of the porous inner wall surface and the exposed outer wall surface of the ceramic, and microscopically, it looks as if each ceramic particle was baked and coated.

This state is referred to as antibacterial agent burning in this specification, but the ceramics fired with this antibacterial agent are finely crushed to form powder (3), and the ceramic is used as a raw material for chemical fiber yarn. Mix with a polymer and stir. At that time, when the flame retardancy is increased, at the same time, an appropriate amount of a flame retardant material (for example, a metal oxide) is mixed and stirred, and the fibers are spun and drawn. The chemical fiber yarn is configured to contain the ceramic powder particles (3), and if the flame retardant is mixed, the chemical fiber yarn (4) has increased flame retardancy.

The pile fabric woven with the chemical fiber yarn (4) constitutes a matte part (2) of a wiped mat, and the matte part (2) is attached to the mat base plate (5). .

Further, the mat portion (2) may be constructed by using only the pile yarn and the chemical fiber yarn (4).

<Regarding Actions and Effects> The chemical fiber yarn (4) constituting the mat portion (2) of the cloth for wipes according to the present invention is (a) a chemical fiber (synthetic fiber) material (b) a ceramic powder (c). Antibacterial agent (d) Flame-retardant material (if necessary) 3 to 4 points.

Next, to describe the mechanism of sustaining the antibacterial effect, the ceramic powder particles (3) baked with the antibacterial agent are evenly present on the surface or inside of the chemical fiber yarn.

Therefore, dust, mud, and the like that have fallen from the soles of the shoes come into contact with the ceramic particles (3), and the antibacterial action works to suppress the propagation of various bacteria. In the case of the conventional type of ceramics impregnated with an antibacterial agent, the antibacterial agent gradually exudes to the outer surface, and the antibacterial effect is enhanced only in the initial stage of use, but the drug is easily dissipated and the sustainability is poor. Since it was a matte cloth, the antibacterial agent, which should be supported in the deep pores of the ceramic, would be washed away for repeated washing, resulting in a further loss of the bactericidal effect.

Therefore, an attempt to carry out the antibacterial action by supporting the ceramic antibacterial agent disclosed in the above-mentioned JP-A-59-133235 or the like and mixing the granular material (3) into the chemical fiber, The effect could hardly be expected for a condition such as a cloth for wipes which is washed frequently and strongly. As a result of microscopic research, a ceramic is prepared by mixing an antibacterial agent, which is widely used in the industry, which is strong against heat, and which is composed of metal ions such as Ag, Cu, and Zn, and a ceramic firing raw material. When fired, it was confirmed that the antibacterial agent strongly adhered to the ceramic front wall surface and porous inner wall surface as if they were baked and painted. Therefore, the duration of the bactericidal effect was dramatically increased as compared with the case of simply impregnated one.

Moreover, although the fibers are worn during actual use, the antibacterial agent-fired ceramic powder (3) is always exposed from the worn part, and sterilized by being present in the mud or dust and between the pile threads. Due to its bactericidal action, its reproduction is suppressed and the generation of malodor is suppressed.

Furthermore, since the ceramic powdery particles (3) are porous and have good affinity with water, the retained water will give a dampness between the wiped mud and the pile yarn, and at the time of washing. It was also confirmed that the mud fell off very well in a short time and the washing time could be greatly shortened. In addition, the ease of washing is that when the powdery ceramics are exposed convexly on the surface of the chemical fiber and the surface of the pile thread (4) is uneven, and if mud or dust adheres to it, it will stick to the fiber thread. This is also because there is a gap between the kimono and the washing water that quickly enters this gap during washing, which facilitates quick washing of mud and dust. This is the same phenomenon as the method for shortening the washing time of laundry and dishes. This hygroscopic property always keeps it moist so that it prevents the mud and dust from being extremely dried, so the mud and dust will not stick to the pile thread, and it will prevent scattering to the surroundings and is hygienic. To work. In addition, when the ceramic powder (3) is mixed in the fiber thread, the thread is stiffer than when it is not mixed, it rises well even when stepped on, and its cushioning effect is also compared to the conventional one. It lasted for a long time, and the napped fibers effectively cleaned the sides of the shoe, and the cleaning effect was extremely good.

Moreover, since the coefficient of friction of the ceramic powder (3) with the shoe sole is increased, the effect of removing mud and dust from the shoe sole is further enhanced.

Furthermore, since the ceramic powder (3) is a fired product at a high temperature, it is highly flame-retardant, and even if a cigarette or the like is accidentally dropped, it is not important.
