Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber structure having an excellent antifouling property, which has not been available in the past.

[0002]

2. Description of the Related Art Hitherto, many fiber structures having antifouling properties have been proposed. Generally, for example, a hydrophilic resin having a hydrophilic group such as polyethylene glycol is provided, or a so-called fluorinated water repellent having a polyfluoroalkyl group in a side chain is provided, or a polyfluoroalkyl group and a hydrophilic group are provided. A resin to which a fluorine-based SR agent is provided and a resin to which both of these resins are provided are known.

[0003] A resin to which a hydrophilic resin has been added has an effect of preventing re-contamination by hardly adsorbing other stains during washing. However, machine oil and the like are easily adhered to the opposite side, and the stains once adhere and dry. It is very difficult to remove even after washing.

[0004] In addition, those provided with a fluorine-based water repellent having a polyfluoroalkyl group have the effect of making it difficult to repel liquid stains, but have the opposite effect of removing stains that have been pushed in by washing. It becomes worse. In addition, those provided with a fluorine-based SR agent having a polyfluoroalkyl group and a hydrophilic group have an effect of repelling both aqueous and oily stains by the polyfluoroalkyl group,
During washing, the effect of the hydrophilic group makes it easier to remove dirt than a fluorine-based water repellent consisting of a polyfluoroalkyl group alone, but the effect is not sufficient.

[0005] All of these fiber structures are stained, and if they are immediately washed, the stains can be removed to some extent.
At present, if left unattended for a long time with dirt attached, it hardly falls off even after washing.

[0006] Japanese Patent No. 2836249 discloses a fiber treating agent and a processing method in which a fluorine-containing phosphoric acid derivative or a salt thereof is combined with a metal chloride, and a fluorine-containing compound. A method of treating with a phosphoric acid derivative or a salt thereof and a metal chloride and then treating with a fluorine-based water repellent is disclosed. A processed article made of a fiber treating agent obtained by combining a fluorinated phosphoric acid derivative or a salt thereof with a metal chloride has high oil repellency, but it is very difficult to remove oil stains once adhered by washing. In addition, for processed products further treated with a fluorine-based water repellent, although the process is complicated and has the effect of repelling dirt, it is very difficult to remove oil stains and the like left after being attached by washing. It was difficult.

Although it is known that a photocatalyst decomposes organic substances, it has not been proposed to use the photocatalyst for removing stains such as oil stains on fibers.

[0008]

SUMMARY OF THE INVENTION In view of the background of the prior art, an object of the present invention is to provide a fiber structure having an excellent antifouling property, which has not been achieved in the past.

[0009]

The present invention employs the following means in order to solve the above-mentioned problems.

That is, the fibrous structure of the present invention comprises a composition A containing a composite oxide composed of titanium and silicon and an alkylsilicate resin, and a resin containing a compound containing phosphorus and a fluoro group and a fluorine-containing resin. The composition B is characterized in that the composition A adheres to the fiber surface in a structure in which the composition A is exposed on the surface.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is directed to the above-mentioned problems, that is, a fibrous structure having excellent antifouling properties, which has not been hitherto known, and a composition containing a specific composite oxide and a specific fluorine-containing resin. When the composition A was combined with the composition and allowed to adhere to the fiber surface in a structure in which the composition A was exposed to the surface, it was found that such a problem could be solved at once.

In the present invention, as the composite oxide of titanium and silicon, an oxide produced by the method described in Japanese Patent Publication No. 5-55184 can be used. Generally, binary composite oxides composed of titanium and silicon are described, for example, in Kozo Tabe (Catalysis, Vol. 17, No. 3, p. 72, 1975).
As described in (1), it is known as a solid acid, and each of the constituent oxides exhibits remarkable acidity not found in a single oxide, and has a high surface area. That is, a composite oxide of titanium and silicon (hereinafter referred to as a photocatalyst) is not simply a mixture of titanium oxide and silicon oxide, but titanium and silicon form a so-called binary oxide,
It can be recognized that the specific characteristics are exhibited. Further, as a result of analysis by X-ray diffraction, the composite oxide has a fine structure that is amorphous or nearly amorphous.

The ratio of titanium to silicon in such a photocatalyst is
It is preferable that titanium oxide and silicon oxide be in the range of 20 to 95 mol% and 5 to 80 mol% in terms of oxide. As the proportion of silicon oxide increases, the photocatalytic activity of titanium oxide tends to weaken, and the optimal proportion may be determined according to the purpose of use.

As a preferred method for producing such a photocatalyst, titanium tetrachloride is mixed with silica sol, ammonia water is added dropwise thereto to form a precipitate, and the precipitate is filtered, washed, dried, and dried at 300 to 100 ° C. Bake at 650 degrees. The photocatalyst thus obtained has a high antifouling property due to its excellent oxidative decomposition properties of organic substances as compared with the titanium oxide photocatalyst manufactured by another manufacturing method, and also has a deodorant property, an anti-odor property, and an antibacterial property. It is characterized by having multifunctional properties such as anti-fungal property, anti-fungal property, anti-atopic property and anti-allergic property.

If the particle diameter or specific surface area of such a photocatalyst is too large, the decomposition rate for organic substances cannot be controlled, and if it is too strong, or if the amount is too small, it will be too weak, and the balance tends to be unbalanced. . The present invention examines the particle diameter and specific surface area of such a composite oxide, and the primary particle diameter is preferably 20 nm or less, more preferably the primary particle diameter is in the range of 1 to 20 nm, and the specific surface area is preferably 100 to 100 nm. Specific to the range of 300 m ² / g,
Preferably, when the photocatalyst was dispersed and diluted, it was found that it was possible to control the resolution and destructive ability of the organic substance, and still exhibit its effective function as it was, and that it could be used safely. Things. That is, a photocatalyst satisfying such a primary particle diameter and specific surface area is:
It can exert its effective function on any organic substance, whether natural or synthetic, and can be used in a state of excellent safety. It can be used without any problem even if it sticks.

The amount of the photocatalyst attached to the fiber structure is preferably 0.05 to 30% by weight. If the content is less than 0.05 wt%, the decomposition rate of organic substances such as stains is reduced, and sufficient antifouling performance cannot be obtained. On the other hand, if it exceeds 30% by weight, the hand becomes hard and may irritate the skin, and when using the fibrous structure as clothing, it tends to cause pain to the user. Further, since the oil repellency is impaired, dirt easily enters into the fiber bundle, and thus the washing removability tends to decrease.

The present invention pays attention to the fact that such a photocatalyst has excellent organic substance decomposability and removal properties (antifouling property), and comprises a composition A containing such a photocatalyst and an alkylsilicate resin, and phosphorus and a fluoro group. The composition B containing the compound to be contained and the fluorine-containing resin is laminated in the order of B / A or adhered in a form in which A and B are mixed. That is, the composition A containing the photocatalyst is arranged so as to be exposed on the surface side, thereby exhibiting the function of the photocatalyst.

By adopting such a structure, the stain is repelled, the stain is easily removed by washing, and the photocatalyst decomposes the stain which is not completely removed but remains inside the fiber bundle. Was obtained. The alkyl silicate resin can also prevent the photocatalyst from decomposing the fiber and the resin composition.

The alkyl silicate resin constituting the composition A is mainly composed of a straight-chain or branched saturated alkyl having a Si—O bonding portion, and has OH groups at both ends thereof. . That is, it includes the structure 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 is an integer of 1 or more, It is preferable that n = 1000 to 10,000 in order to increase the value.

The alkyl group is a linear or branched saturated alkyl such as methyl, ethyl, propyl, isopropyl and the like. These alkyl silicate resins are one kind,
A mixture of two types may be used. These compounds are characterized by easily causing a dehydration reaction in the presence of heat to form a polysiloxane coating. Alkyl silicate is water-soluble, and after impregnating a fiber structure to be processed with these aqueous solutions, squeezing with a mangle roll and treating at a temperature of 200 degrees Celsius or less, the surface of the fiber of the fiber structure becomes It forms a thin film. The alkyl silicate resin is used in an amount of 0.04 to 0.85 wt based on the fiber structure.
% Is preferable. If it is less than 0.04 wt%, the photocatalyst may decompose the fiber structure or such a resin composition, and if it is 0.85 wt% or more,
It impairs antifouling properties.

As the compound containing phosphorus and fluoro group constituting the composition B, a compound represented by the following general formula [I] is preferable. Since such a compound has high oil repellency, the effect of repelling an oil component such as mechanical oil which tends to enter the inside of the fiber bundle or the inside of the fiber bundle by adhering to the fiber surface is greatly improved.
