Description of the Related Art In recent years, interest in comfort in a living environment has been increasing, and various proposals have been made regarding removal of offensive odors existing in a room, in a refrigerator, in a company, or in various environments. In particular, the deodorization of tobacco odors in offices, homes, and automobiles has been highlighted with the spread of smoking cessation campaigns. Various products using deodorant fibers have been developed for removing tobacco odor, and deodorant fibers are used in the raised portions of nap products such as so-called bores and high piles such as stuffed animals, blankets, and carpets. However, despite the fact that relatively large amounts of deodorant fibers are used in the napped portions of these products, the deodorant effect expected from the fiber weight, especially the deodorant effect against cigarette smoke, cannot be obtained. In addition, there is a problem that the deodorizing speed is low. Furthermore, even after removing odor components in the air with deodorizing fibers, the components adsorbed due to environmental changes may be re-released from the deodorizing fibers and emit a bad smell, and a semi-permanent deodorizing effect cannot be obtained. There was also.

発明に到達したものである。Means for Solving the Problems In view of the above problems, the present inventors have conducted intensive studies and as a result, have found that the smoke component of cigarettes contains not only gas but also a large amount of liquid droplets, which also considerably contributes as odor. And when the single yarn denier of the napped part is composed only of the hair growth of 5d or less, the droplets of the cigarette smoke concentrate on the tip of the hair growth and occupy most of the surface area of the deodorant fiber. Paying attention to the fact that adhesion to the fiber side surface is hardly obtained, there is a stabbed portion with a pile length longer than the hair growth layer in the nap portion, so that the odor component is also attached to the fiber side surface of the stabbed portion, In addition, the use of fibers with photocatalytic activity as deodorizing fibers significantly improves the deodorizing performance as well as the deodorizing performance, prevents odor components from being re-released, and maintains a semi-permanent deodorizing effect.

ある。Hereinafter, the present invention will be described in more detail. The napped fabric used in the deodorized napped product of the present invention has a denier of 5 d or less, preferably 3 to 5 d, from a hair-growing component and a bristle component. If the single yarn denier of these components is less than 5 d, the piloerection is poor, and the superior deodorizing effect and deodorizing speed of the stabbing component cannot be obtained. There is no particular limitation on the proportion of the hair-growing component and the hair-stitching component, and it can be appropriately selected according to the amount of the fiber having photocatalytic activity contained in the hair-stripping component, the required characteristics of the product, and the like. The deodorizing performance includes a function of removing not only a single odor component but also a complex odor such as the odor of cigarette smoke.

てその活性を向上させることができる。[0007] The length of the stab component used in the present invention must be at least 1 mm longer than the hair growth component in pile length.
The preferred pile length difference between the two is in the range of 2 to 5 mm. When the pile length difference between the two is less than 1 mm, the adhesion of the malodorous component to the side surface of the deodorant fiber constituting the bristle component is reduced, and an excellent deodorizing effect and deodorizing speed cannot be obtained. In addition, the stabbing component in the present invention contains fibers having photocatalytic activity against odorous components in the air. Here, the photocatalytic activity refers to the action of developing a catalytic action by light irradiation and decomposing odorous components in the air by a chemical reaction such as an oxidation reaction.For example, holes are generated in the catalyst by light irradiation and active oxygen Means that odorous components in the air are decomposed by an oxidation reaction or the like due to generation of odor. The fiber having photocatalytic activity can be obtained by introducing particles having photocatalytic activity into the fiber. The particle having photocatalytic activity is not particularly limited as long as it has the photocatalytic activity as described above, and examples thereof include titanium oxide and zinc oxide. Among these, titanium oxide is preferable because of its strong oxidizing power, and anatase-type titanium oxide having high photocatalytic activity is particularly preferable. The activity can be improved by doping titanium oxide with a metal such as palladium or copper.

る。As a method for adhering particles having photocatalytic activity to the fiber, a method in which the particles are kneaded into a stock solution for spinning the fiber and spun, and a photocatalytic sol is applied in a gel-swelled state by a dip nip method during wet spinning From the viewpoint of sufficiently exhibiting the activity of the photocatalyst, the latter method capable of adhering photocatalyst particles to the fiber surface is effective. The dip nip method is a method of immersing the photocatalyst in a processing liquid in which the photocatalyst is dispersed in a continuously spread state, and immediately squeezing the liquid with a nip roller such as a mangle to give a desired amount of adhesion. The content of the particles having photocatalytic activity with respect to the fiber is not particularly limited, but is usually 0.1% with respect to the fiber.
It is 1 to 10% by weight, preferably 0.3 to 5% by weight.
When the content of titanium oxide is less than 0.1% by weight, organic substances,
In particular, compounds having a carbonyl group and acidic compounds have a low decomposition performance due to catalytic action against bad smell. On the other hand, if it exceeds 10% by weight, it becomes difficult to contain titanium oxide in the fiber, and the physical properties of the fiber deteriorate, Problems such as lowering and further winding of the fiber in a later step, for example, a spinning step, and abrasion of the spinning machine occur. The size of the titanium oxide is not particularly limited as long as the production of the fiber is not hindered, but is preferably 0.07 μm or less from the viewpoint of easy attachment to the fiber. The particle size of the titanium oxide can be measured by measuring the particle size of the titanium oxide present in the dispersion using a laser diffraction scattering type particle size distribution analyzer (LA-910W, manufactured by Horiba, Ltd.).

The fiber containing the photocatalytic activity is not particularly limited, but a synthetic fiber having a small strength reduction due to self-deterioration due to the photocatalytic activity is preferable, and more preferably a synthesis by wet spinning capable of providing particles having the photocatalytic activity in a gel swelling state. Fibers such as polyacrylonitrile-based synthetic fibers are preferred. Fibers having such a photocatalytic activity are used for stabbed hair (piling component) of nappied fabric.
However, ordinary fibers and deodorant fibers described below can be used in combination within a range that does not impair the object of the present invention. Further, in order to increase the surface area of the fiber and enhance the deodorizing effect, a fiber having a flat cross section can be used as stab hair.
