2. Description of the Related Art In recent years, many deodorant processing methods have been proposed for textile products because of the necessity of creating a healthy and comfortable living environment. For example, mixed spinning in which a deodorant substance is kneaded into a thermoplastic polymer. Method (Japanese Patent Application Laid-Open No. 2-44950) in which a deodorant substance is fixed to a fiber through a polymer resin binder by a method (JP-A-2-234917) or a post-treatment method.
Are known. In the former mixed spinning method, it is considered that the deodorant function is mainly expressed on the surface of the textile product, so that the action efficiency of the deodorant substance on the function expression is low. Furthermore, when the fiber surface constituting the textile product is coated with a treatment agent in the post-treatment step,
The deodorant function is significantly reduced. On the other hand, in the latter coating method, the surface of the applied deodorant substance is covered with a film-forming resin such as a polymer resin binder, and as a result, the deodorizing ability tends to decrease. Further, depending on the type of the resin binder, there are problems such as toxicity to the human body and skin rash.

The present inventors have arrived at the present invention as a result of intensive studies to solve the above problems. That is, the present invention is a fabric made of a thermoplastic polymer fiber, wherein a ceramic fine porous body is supported on a cellulose fine powder, and the ceramic fine porous body is fixed to the fabric by using the cellulose fine powder as a medium. And a deodorant fabric obtained by adding a deodorant to the ceramic microporous body, and a fabric composed of a thermoplastic polymer fiber,

These are referred to as deodorants) are fixed. The fibers constituting the fabric of the present invention are made of a thermoplastic polymer having a fiber-forming property such as long fibers or short fibers, and are made of a single polymer, or two or more kinds of polymers are core-sheath. It is a composite of molds or side-by-side molds. Examples of the thermoplastic polymer include polyester such as polyethylene terephthalate, polybutylene terephthalate, and copolyester, linear low density polyethylene, low density polyethylene, high density polyethylene, polyolefin such as polypropylene, nylon 6, nylon 66, nylon 610, nylon.
Examples include polyamides such as 46, and in the case of composite fibers,
Examples include a combination of polyethylene terephthalate and high density polyethylene, a combination of polypropylene and linear low density polyethylene, and a combination of a homopolymer of polypropylene and a polypropylene copolymer in which ethylene is randomly copolymerized.

Next, the case where the deodorant fabric of the present invention is a non-woven fabric will be described in detail. The non-woven fabric is composed of long fibers or short fibers made of the above-mentioned thermoplastic plastic copolymer, has a basis weight of 5 g / m ² or more and 200 g / m ² or less, and a basis weight of less than 5 g / m ^2. Is not so low that it is difficult to produce a uniform nonwoven fabric, and its utility value as a nonwoven fabric is poor. On the other hand, the basis weight is 200
When it exceeds g / m ² , the basis weight is too high and the nonwoven fabric becomes thick and hard, which is not preferable for use as a material for medical hygiene materials and bedding materials. Although the single yarn fineness of these fibers is not particularly limited, it is preferably 5 denier or less, and more preferably 2 denier or less particularly when flexibility is required in applications such as medical hygiene materials and bedding materials. The cross-sectional shape of the fiber may be an irregular shape such as a round shape or a triangular shape, or may be a hollow cross-sectional shape.

As described above, the deodorant cloth having hydrophilicity according to the present invention is a deodorant material such as a ceramic microporous material supported on cellulose fine powder and a synthetic resin microcapsule containing a deodorant. The body is fixed. Since the ceramic microporous body has an adsorption area much wider than that of activated carbon, it has a property of adsorbing a malodorous substance even if it is used as it is. You may make it contain. The ceramic microporous body contains ceramic silica as a main component and is usually manufactured by a known method such as a sol-gel method. Furthermore, the synthetic resin microcapsules
It is made of gelatin, polyvinyl alcohol, polyacrylic acid, polyamide, urea formalin resin and the like, and is produced by a method such as coacervation, a phase separation method, a polymerization method or an air suspension method.

Although a deodorizer composed of a metal ion such as nickel is used, it is not particularly limited. The deodorants may be used alone or in combination of two or more.

The cellulose fine powder is a fine powder obtained by crushing cellulose pulp with a disc refiner or the like to make it fine, and has a diameter of about 0.1 μm and a length of several hundreds of μm.
It is made of fine short fiber cellulose.
The cellulose fine powder does not have to have a high purity and may be any that can be suspended in water.

Next, a method for producing a deodorant nonwoven fabric in the deodorant fabric of the present invention will be described. When the deodorant non-woven fabric is composed of long fibers, first, long fibers made of the polymer are spun using an ordinary melt-spinning apparatus, taken out by a take-up means such as an air sucker, opened, and then a web conveyor. It is deposited on the collecting surface such as to form a web, or is continuously drawn by a take-up roller while being drawn between a take-up roller and a draw roller, and then opened to obtain a web. The take-up speed depends on the fineness of the single yarn and the kind of the polymer, but usually, when using a take-up means such as an air sucker, about 2500 to 5000 m / min,
When using a take-up roller, 100 to 500 m /
It is good to set it to about a minute. Next, the obtained web is embossed using an embossing roller to obtain a nonwoven fabric. The embossing conditions are such that the linear pressure of the embossing roller is usually 30 to 100 kg / cm and the temperature of the embossing roller varies depending on the kind of the thermoplastic polymer, but is about 5 to 30 ° C. higher than the melting point of the thermoplastic polymer constituting the fiber. Use low temperature. In the case of a composite fiber, it is preferable that the temperature is lower by about 5 to 30 ° C. than the melting point of the low melting point component of the polymer constituting the fiber.

Next, the case where the deodorant nonwoven fabric is composed of short fibers will be described. A long fiber made of the above-mentioned polymer is spun using an ordinary melt spinning device, the spun yarn is once wound, and a plurality of the obtained undrawn yarn packages are collected and drawn in a tow state. At the time of spinning, the take-up speed is usually about 100 to 1500 m / min. The focused tow is stretched in two or more stages. In the stretching, the stretching ratio depends on the type of polymer constituting the fiber and the strength level required for the short fibers, but it is usually about 1.5 to 6.0 times. Then, after subjecting the stretch-treated tow to mechanical crimping using a stuffer type crimping device or the like,
Cut into a short length to make short fibers. The number of crimps depends on the bulkiness required for the nonwoven fabric, but is usually 8 to 2
The number is about 0 / inch.

Next, a web is prepared using the short fibers obtained as described above. The web formation can be made by using a card machine or a papermaking method. Next, the obtained web is embossed by using, for example, an embossing roller to obtain a nonwoven fabric. The embossing condition is usually a linear pressure of the embossing roller of 30 to 100 kg.
/ Cm, and the temperature of the embossing roller is set to a temperature lower by about 5 to 30 ° C. than the melting point of the thermoplastic polymer constituting the fiber, although it depends on the type of the thermoplastic polymer. When the fiber is a composite fiber composed of two or more kinds of polymer components having different melting points, it is 5 to more than the melting point of the low melting point component constituting the fiber.
It is preferable to set the temperature as low as about 30 ° C. Further, when a nonwoven fabric is prepared by heat fusion treatment using a thermal calendar roller or the like, the treatment temperature is about 5 to 30 ° C. lower than the melting point of the polymer constituting the fiber. When the fiber is a composite fiber composed of two or more kinds of polymer components having different melting points, it is preferable that the temperature is lower by about 5 to 30 ° C. than the melting point of the low melting point component among the polymers constituting the fiber. ..
When a nonwoven fabric is prepared by heat fusion treatment using a hot air circulation dryer, the treatment temperature is about 30 ° C. higher than the melting point of the polymer constituting the fiber, and the treatment time is 5 to 5. 120 seconds is good.

Next, the deodorant is added to an aqueous suspension of cellulose fine powder, and the uniformly treated mixed treatment liquid is applied to the nonwoven fabric. The coating method may be any method such as a dipping method, a spraying method, a pad dry method or a printing method. The application may be performed either after the fiber is spun and during the winding of the non-woven fabric, but it is usually applied in a separate applying step provided between the formation of the web and the winding of the non-woven fabric.

The treatment liquid is adjusted by the following method. First, add ion-exchanged water to cellulose fine powder,
An aqueous suspension of cellulose fine powder is prepared by stirring. Then, the deodorant is added to the aqueous suspension of the cellulose fine powder and stirred uniformly, whereby the deodorant is dispersed in the aqueous suspension of the cellulose fine powder, and precipitates even when left standing. It is possible to prepare a treatment liquid that does not have a problem. In particular, it is possible to prepare a stable treatment liquid that does not sediment for a long period of time even for a ceramic microporous body having a high specific gravity.

Next, a deodorant is added to an aqueous suspension of the cellulose fine powder and the mixture is uniformly stirred to apply the treatment liquid to the nonwoven fabric, followed by drying and heat treatment.
Drying and heat treatment, using a normal hot air circulation dryer,
The deodorant supported on the cellulose fine powder is fixed on the surface of the constituent fibers of the non-woven fabric by evaporating the water and performing the heat treatment. The heat treatment temperature is usually 5 ° C. or more lower than the melting point of the thermoplastic polymer constituting the nonwoven fabric. Drying and heat treatment may be performed with a hot calendar roll. The coating speed may be the production speed of the non-woven fabric, usually 2 to 50 m / min, and does not limit the production speed at all. The amount of application to the nonwoven fabric is adjusted by changing the concentration of the treatment liquid depending on the difference in the coating method, the coating speed, the viscosity of the treatment liquid, and the like. In addition, the amount of deodorant adhered to the non-woven fabric is 0.05 to the weight of the non-woven fabric in consideration of the deodorant effect, the texture of the non-woven fabric, the effect on the flexibility, and the economical efficiency.
15% by weight is preferred. The amount of the fine cellulose powder adhered may be appropriately adjusted in relation to the amount of the deodorant to be applied, the suspension dispersibility of the deodorant in the treatment liquid, and the hydrophilicity required for the deodorant nonwoven fabric. .. As described above, the application of the treatment liquid may be online in the nonwoven fabric manufacturing process, or may be offline in which the nonwoven fabric once wound is applied. Further, even if the cloth is a woven or knitted fabric composed of long fibers or spun yarn, an excellent deodorant cloth can be obtained by performing the same processing as the above-mentioned non-woven fabric.

[0016]

As described above, the hydrophilic deodorant cloth of the present invention comprises a cloth made of a thermoplastic polymer fiber and a ceramic microporous material supported on cellulose fine powder and a deodorant. Since a deodorant such as a synthetic resin microcapsule is fixed, not only excellent deodorant properties are exhibited but also hydrophilicity is exhibited.
