Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cotton pad product having excellent durability and odor prevention, deodorant, antibacterial, antifungal and antifouling properties which have never been obtained. More specifically, it relates to cotton wrapping products such as comforters, mattresses, pillows, kotatsu comforters, cushions, and stuffed animals.

[0002]

2. Description of the Related Art In recent years, awareness of sports, health and hygiene has increased with the improvement of people's living standards.
Deodorized, antibacterial, antifungal and antifouling products have been put to practical use in various fields such as clothing, food and living.

Comforters in the field of bedding and interiors,
Even for cotton wrapping products such as mattresses, pillows, kotatsu quilts, cushions, and stuffed animals, there is a strong need for deodorant, antibacterial, and antifouling properties, but processing technology has not been developed.

It is said that a person perspires about 200 cc of sleep while sleeping overnight, and the perspiration may permeate into the futon through the duvet cover or sleepwear. At the same time, sebum containing nutrients is secreted from the surface of the skin and old keratinocytes fall off, which causes soiling of the futon. It has been experienced that various microorganisms (staphylococcus, Escherichia coli, Pseudomonas aeruginosa, etc.) decompose these stains to generate a bad odor. In winter, when the kotatsu is used, the smell of sweat, which contains ammonia and isovaleric acid secreted from the soles of the feet, is trapped inside the kotatsu, often resulting in an unbearable odor. For this reason, the need for deodorizing cotton-padded products is extremely high.

On the other hand, in the conventional technology, the unpleasant odor is eliminated by using the deodorant spray. in this case,
The offensive odor is temporarily suppressed, but the odor that has soaked into the cloth is generated again, which does not lead to a fundamental solution. In other words, this method cannot eliminate the smell of the cloth.

There is also a technique of adhering or coating a specific chemical on a fiber cloth, but there is a problem that the cloth is colored or discolored or the fiber is deteriorated. Furthermore, it is difficult to eliminate the odor once soaked in the cloth, and it is not easy to completely remove the bacteria and mold attached to the cloth.

[0007]

In view of the background of the prior art, the present invention has no discoloration or deterioration in use, has a persistent odor preventing / deodorizing effect, and further has antibacterial, antifungal and antifungal properties. It is intended to provide a cotton pad product having an excellent function that satisfies the stain property at the same time.

[0008]

The present invention employs the following means in order to solve the above problems. That is, the cotton wadding product of the present invention is a cotton wadding product consisting of a batting cotton and a side material, and the side surface has at least one binder selected from an alkyl silicate resin, a silicone resin and a fluorine resin. And a photocatalyst agent.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a photocatalytic agent is
It has the property of being excited by ultraviolet rays and oxidatively decomposing organic substances with a strong oxidizing power, and specifically includes those having a crystal type structure called anatase type or rutile type. Such a photocatalyst has a deodorant property, a colorant decomposition and removal property (antifouling property), and a bactericidal property (antibacterial property, antifungal property).

The action of such a photocatalytic agent is that the odor of sweat (main components: ammonia and isovaleric acid) is generated due to the indigenous bacteria existing around the skin in the water produced from the eccrine gland and apocrine gland under the skin, This odor was excited by photocatalyst
H group (hydroxyl radical) touches the main component of sweat,
It is believed to decompose into O ₂ (carbon dioxide gas) and H ₂ 0 (water) to deodorize.

In addition, in the aging odor (middle-aged odor), the main components are:
In case of nonenal, old-fashioned odor (middle-aged odor), main ingredients: indole, skatole, in manure odor, main ingredient: ammonia, in other body odors, main ingredients: acetaldehyde, methyl mercaptan, in tobacco odor, main ingredient: Nicotine can be decomposed by photocatalytic agents in the same manner.

In the present invention, it is preferable to use a composite oxide of titanium and silicon among the photocatalytic agents, and such a composite oxide is disclosed in JP-B-5-55184.
The catalyst produced by the method described in the publication may be used. Generally, a binary compound oxide composed of titanium and silicon is disclosed in, for example, Kozo Tabe (Catalyst, Vol. 17, No. 3, 72).
, 1975, published by The Catalysis Society of Japan).
Known as a solid acid, those in which the ratio of titanium to silicon is in the range of 20 to 95 mol% of titanium oxide and 5 to 80 mol% of silicon oxide in terms of oxides give preferable results.

If the particle size of such a photocatalyst is too large or the specific surface area is too small, the rate of decomposition of organic substances, particularly bacteria, tends to decrease. Further, as described above, the deodorizing reaction is considered to be a process in which the malodorous component is adsorbed on the catalyst and then undergoes ultraviolet oxidative decomposition, and whether or not the malodorous component is adsorbed greatly affects the deodorizing efficiency. Therefore, the average primary particle size is preferably 1 to 20 nm, and the specific surface area is preferably 1
Those having an amount of from 00 to 300 m ² / g are preferably used.

The amount of the photocatalyst attached to the fiber structure is preferably 0.05 to 30% by weight, more preferably 0.05 to 20% by weight in the method of applying the photocatalyst to the fabric by printing or gravure. Further, in the method of impregnation with padding, it is preferable to control the content to be in the range of 0.08 to 10% by weight from the viewpoint of softness of texture.

In the present invention, for adhering a photocatalytic agent such as a composite oxide of titanium and silicon to the fiber surface, at least one binder selected from alkyl silicate resins, silicone resins and fluorine resins is used. To use. The presence of such a binder can prevent the photocatalytic agent peculiar to the organic resin from being decomposed, colored, and odorous due to oxidation.

The alkyl silicate used in the present invention is characterized in that it is mainly composed of a Si--O bond and a saturated alkyl having a straight chain or a branch, and has OH groups at both ends thereof. That is, it includes the structures shown below.

OH- (Si-O) _n- R-OH In the formula, R is a linear or branched saturated alkyl group having 1 to 10 carbon atoms, n means an integer of 1 or more, and is an inorganic In order to enhance the property, n is preferably 1000 to 1000
The range of 0 is preferable.

The alkyl group is a linear or branched saturated alkyl such as methyl, ethyl, propyl and isopropyl.

From the viewpoint of improving the texture, the amount of the resin adhered is preferably 0.05 to 30% by weight with respect to the fibers by the coating method, and is 0.0 with respect to the fibers by the impregnation method.
5-10% by weight is preferred.

As the silicone-based resin, a condensation-crosslinking type resin belonging to the category of silicone resin or silicone varnish can be used. Such a resin is a condensation-crosslinking type resin such as tetraethoxysilane or methyltrimethoxysilane. , Which can be obtained alone or by condensing several kinds of compounds. These are 3
It forms a resin having a three-dimensional structure and has the highest heat resistance and chemical resistance among silicone resins.

From the viewpoint of improving the texture, the coating amount of the resin is 0.05 to 100 with respect to the fiber by the coating method.
% By weight, and in the impregnation method, it is preferably 0.05 to 30% by weight with respect to the fiber.

As the fluorine-based resin, vinyl ether and / or vinyl ester and a fluoroolefin polymerizable compound are preferably used because they have very excellent characteristics. For example, polyvinyl fluoride, polytetrafluoroethylene, tetrafluoroethylene-perfluoroalkyl vinyl ester, vinyl ester-fluoroolefin and the like are preferably used because they are less decomposed and deteriorated.

The amount of such a resin attached is preferably the same as that of the silicone resin. From the viewpoint of improving the texture, the amount of the resin attached is preferably 0.05 to 100% by weight with respect to the fibers in the coating method, and 0.05 to 30% by weight with respect to the fibers in the impregnation method. preferable.

[0024] Such silicone resin and fluorine resin, and commonly used acrylic resin, urethane resin,
The difference with epoxy resin is that it contains almost no hydrocarbon groups that are easily decomposed by the action of heat or chemicals, silicone resin is mainly composed of Si-O bond, and fluorine resin is mainly composed of FC bond, It is in the extent that a small amount of methyl group or phenyl group is contained as a hydrocarbon in the terminal group or side chain.

Further, it is preferable to add zeolite to the binder because it has the effect of further enhancing the antibacterial performance. That is, it has the effect of improving the adsorptivity of odorous components and increasing the ratio of inorganic components in the structure to suppress decomposition by the photocatalytic agent.

When such a zeolite carrying a noble metal such as gold, platinum, silver or palladium, which is supported in the range of 0.01 to 5% by weight, is used, the antibacterial effect is further enhanced. The amount of such zeolite attached is preferably 0.01 to 1 with respect to the fiber in the coating method.
0% by weight, and in the impregnation method, in terms of texture,
It is preferable to control it in the range of 0.01 to 5% by weight.

Next, by adding a coupling agent such as a silane coupling agent to the above-mentioned binder, the adhesive force between the inorganic substance and the organic substance can be improved. The coupling agent exerts a chemical bonding force between the fiber, the binder, and the photocatalyst agent to exert the effect of significantly improving the washing durability.

The amount of the coupling agent attached to the fiber is preferably 0.01 to 30% by weight with respect to the fiber, and the impregnation method is preferably 0.01 to 10% from the viewpoint of texture. It is preferable to control in the range of weight%.

Next, on the fiber surface constituting the cotton wadding product,
An example of a method of applying the binder and the photocatalytic agent will be described.

A working liquid containing such a photocatalytic agent and a binder may be applied to the cloth. The method is not particularly limited, for example, by impregnating a fabric with a processing liquid containing a binder and a photocatalyst, squeezing with a mangle roll, and performing a dry-cure process, so-called ordinary resin processing of fabric. It is carried out according to the above conditions, but it is preferable to select conditions that take into consideration the direction of maintaining air permeability. Dry-cure temperature x time conditions are dry: 110-1
35 ° C x 1 to 3 minutes, cure: 160 to 190 ° C x 1 to 3
The condition of about minutes is preferably adopted.

In the coating process such as printing and gravure,
This processing liquid is adjusted to an appropriate viscosity with a sizing agent, applied with a knife coater, gravure roll coater, printing, etc., and then fixed under temperature conditions of 170 to 200 ° C. for 5 to 30 minutes, so-called normal printing. Processing and gravure processing can be preferably adopted.

In this way, it is possible to provide a Japanese clothes having extremely excellent functionality which satisfies the odor prevention, deodorant, antibacterial, antifungal, and antifouling properties which have not been achieved in the past. According to the present invention, since the photocatalyst agent is applied to the fiber cloth together with the specific binder, the functionality is not deteriorated even when industrially washed. Further, since the photocatalytic agent is used, the performance will not be deteriorated by the detergent during washing.

The cotton pad of the present invention is a fiber cloth made of synthetic fibers such as polyester, polyamide, acrylic and polylactic acid fibers, semi-synthetic fibers such as acetate and rayon, and natural fibers such as wool, silk, cotton and hemp. Can be used. From the viewpoint of improving durability, dimensional stability, light weight, and high strength, it is preferable to use mainly polyester fibers, from the viewpoint of improving hygroscopicity and water absorption,
A fiber cloth using a mixed yarn of polyester fiber and cotton, or a mixed woven or knitted pattern of the polyester fiber and the cotton yarn is preferably used.

Here, as the polyester fiber, polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, polyhexamethylene terephthalate, etc. are preferably used. Further, as the polyester constituting the polyester fiber,
Copolymerization of the third component can also be used, and as the third component, it is preferable to use copolymerization of isophthalic acid, 5-sulfoisophthalic acid, metoxypolyoxyethylene glycol or the like.

In the present invention, the polyester fiber may contain an inert titanium oxide. The inactive titanium oxide is titanium oxide that is inactive without being excited by light having a specific wavelength, particularly preferably ultraviolet rays, preferably titanium oxide used as a matting agent in the production of polyester-based synthetic fibers. used. By adding such an inactive titanium oxide, the inorganicity is enhanced by adding the inorganic titanium oxide to the 100% organic polyester fiber, and the redox effect of the photocatalytic agent present on the fiber surface on the polyester fiber is increased. It is believed to reduce the effects of action. Such inert titanium oxide can be added at the time of polymerization of polyester fiber, and has an average particle size of preferably 0.1 to 0.1 from the viewpoint of yarn-forming properties and yarn physical properties.
The thickness is preferably 0.7 μm, more preferably 0.2 to 0.4 μm.

The amount of the inert titanium oxide added is preferably 0.3 to 5% by weight, more preferably 0.5 to 4% by weight, based on the weight of the fiber. . When it is less than 0.3% by weight, the polyester fiber is easily decomposed by the photocatalytic agent, and the photocatalytic function and the physical properties as the fiber structure cannot be maintained with good durability. On the other hand, if it exceeds 5% by weight, it is not possible to obtain products having satisfactory yarn-forming properties and yarn physical properties.

The cross-sectional shape of the fiber used in the present invention is not particularly limited, and either a round cross section or a modified cross section can be used. The modified cross section is preferable because the surface area of the fiber is large and the functionality imparted to the fiber is higher than that of the round cross section. Since the spinning becomes difficult when the degree of irregularity becomes high, the irregularity section modulus is preferably 1.2 to 2, and 1.3 to 1.8.
Is more preferable. The irregular section modulus here is the ratio of the outer peripheral length of the irregular cross section to the outer peripheral length of a perfect circle having the same cross-sectional area as the irregular cross section, and specifically,
It is a value obtained by dividing the outer circumference of the modified cross-section fiber by the outer circumference of the perfect circle cross-section fiber. It is considered that the larger this value is, the larger the surface area per yarn weight is, so that the area of the photocatalyst layer is also increased and the functionality imparted to the fiber is improved. In particular, as the fibers used for the lateral side, "Theo-Alpha" (registered trademark), "Airfine" (registered trademark), "Supp" (registered trademark) (both manufactured by Toray Industries, Inc.), which are excellent in water absorption, are used. preferable. A polyester / cotton blended yarn is also preferably used for the side fabric.

As the polyamide fiber, nylon 6 and nylon 66 are preferably used.

The fiber form of synthetic fibers such as polyester and polyamide is not particularly limited, but spun yarn and filament yarn are preferably used. Since a filament yarn can impart stretchability, a crimped yarn (a woolly yarn, a buleria yarn, a composite yarn, etc.) is preferably used. Further, such synthetic fibers may include chemical fibers such as acetate and rayon, and natural fibers such as wool, silk, cotton and hemp.

Includes comforters, pillows, kotatsu comforters, cushions, plush toys, and more.

The cotton wadding product of the present invention is characterized by being excited by ultraviolet rays and oxidatively decomposing organic substances by a strong oxidizing power. At the same time, although it cannot be fully explained in principle, it is used for kotatsu and the like. Deodorizing performance is exhibited even in the overheated state caused by irradiation of the infrared lamp.
