（産業上の利用分野）
本発明は、空気清浄機のフィルター、寝具、カーベント

その製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a deodorizing nonwoven fabric used as a material for air cleaner filters, bedding, car vents, clothing, etc., and a method for producing the same.
（従来の技術）
多孔質ガラス繊維は三次元の細孔を無数にもったガラス
繊維で、高ケイ酸質であるため耐薬品性、耐熱性に優れ
、かつ多孔質のため気体分子の吸着性に優れているので
、各種ガスの吸着剤や脱臭剤として利用されつつある。(Conventional technology) Porous glass fiber is a glass fiber with countless three-dimensional pores, and because of its high silicic acid content, it has excellent chemical resistance and heat resistance, and because it is porous, it has excellent adsorption properties for gas molecules. Because of its excellent properties, it is increasingly being used as an adsorbent for various gases and as a deodorizing agent.

、ＳｉＯ□を主成分とした多孔質ガラス繊維が得られる
。In order to produce the porous glass fiber, glass having a phase-separated borosilicate composition is melted, formed into fibers by a known method, and then heat-treated to separate an acid-soluble phase and a poorly soluble SiO □
phase and then remove the acid-soluble phase by acid treatment. To express. As a result, the SiO□ phase hardly dissolves in the acid and remains in its original shape to form a three-dimensional network structure, resulting in a porous glass fiber containing SiO□ as a main component.

点がある。(Problems to be Solved by the Invention) However, since porous glass fibers are used while being stored in an air-permeable container or the like in their fibrous state, they are inconvenient to handle. Furthermore, although porous glass fibers have excellent deodorizing power against basic gases such as ammonia, they have a drawback in that they are inferior in deodorizing power against acidic gases such as hydrogen sulfide.
ところで、多孔質ガラス繊維の取り扱い性を向上させる

るものである。By the way, in order to improve the handling properties of porous glass fibers, they may be made into non-woven fabrics. There are various methods for producing nonwoven fabrics, but the wet method is simple. That is, short fibers are dispersed in an aqueous solution (dispersion medium) containing a water-soluble binder, and this is poured onto a wire mesh, dehydrated, and dried.

ため所期の不織布が得られない。However, when attempting to manufacture a nonwoven fabric using porous glass fibers, the water-soluble binder permeates into the pores, which impairs adsorption. In addition, if a nonwoven fabric is manufactured using split-phase glass fiber before acid treatment and then acid treatment is performed to make it porous, the water-soluble binder will dissolve in the acid solution during the acid treatment process, and the fibers will become porous. Because of redispersion, the desired nonwoven fabric cannot be obtained.
本発明はかかる問題点に鑑みなされたもので、塩基性の

なることを発明の構成とするものである。(Means for Solving the Problems) The nonwoven fabric of the present invention made to achieve the above object has the following features:
The structure of the invention is that porous glass fibers and activated carbon fibers are entangled with each other, and the fibers are partially adhered to each other by melting heat-fusible synthetic fibers.

The dispersion medium is removed and dried to obtain a phase split glass fiber nonwoven fabric, the nonwoven fabric is heated to melt the synthetic fibers and the fibers are partially adhered to each other, and then the phase split glass fiber nonwoven fabric is subjected to an acid treatment. The composition of the invention is to elute the acid-soluble phase, wash it with water, and dry it.

しうる。(Function) The porous glass fibers constituting the nonwoven fabric have excellent deodorizing properties for basic gases, and the activated carbon fibers have excellent deodorizing properties for acidic gases, so the nonwoven fabric of the present invention has good deodorizing properties for both gases. It becomes what it is. In addition, since both fibers are partially bonded by melting heat-fusible synthetic fibers, their strength is increased without compromising their deodorizing ability, and combined with the fact that they are non-woven fabrics, they are extremely easy to handle. , can be used as various materials.

が均一に分散し、からみ合った状態となっている。On the other hand, according to the manufacturing method of the present invention, the water-soluble binder in the dispersion medium imparts bulkiness and strength to the phase-divided glass fiber nonwoven fabric, making subsequent handling easier. In the nonwoven fabric, phase split glass fibers, activated carbon fibers, and heat-fusible synthetic fibers are uniformly dispersed and entangled.

って、不織布は水溶性バインダーと合成繊維の融着とに
よって保形される。When the formed phase split glass fiber nonwoven fabric is heated, some or all of the heat-fusible synthetic fibers in the nonwoven fabric melt, and the glass fibers and activated carbon fibers are partially bonded to each other. As a result, the shape of the nonwoven fabric is maintained by the fusion of the water-soluble binder and the synthetic fibers.
その後、該分相ガラス繊維不織布に対して酸処理を行う

生じさせるおそれはない。Thereafter, the phase split glass fiber nonwoven fabric is subjected to acid treatment. At this time, the water-soluble binder dissolves in the acid solution and the shape retention effect disappears. However, since the glass fibers and the like are kept in shape by fusing the synthetic fibers, the fibers will not be redispersed in the acid solution. Moreover, since the synthetic fibers are only partially fused, the elution of the acid-soluble phase is not hindered, and the phase-separated glass fiber can be made porous. Note that since the amount of the water-soluble binder redissolved in the acid is small, there is no risk of clogging the pores.

布が形成される。The phase-separated glass fibers, activated carbon fibers, and heat-fusible synthetic fibers are stirred and dispersed in an aqueous solution (dispersion medium) in which a water-soluble binder such as hydroxyethyl cellulose (HEC) or polyvinyl alcohol (PVA) is dissolved. . The concentration of the binder is approximately 0.5 to 5 wt%. Then, it is separated by a wire mesh for filtration and dried to form a nonwoven fabric.

溶相の溶出を速やかに行うことができ好適である。Next, the phase split glass fiber nonwoven fabric is heated to melt the heat-fusible synthetic fibers and partially bond the glass fibers together. The heating temperature varies slightly depending on the type of synthetic resin, but is approximately 100 to 120°C. When using a semi-melting type synthetic fiber, it is heated at a temperature intermediate between the melting temperature of the low melting point component and the melting temperature of the high melting point component. A semi-melting type is preferable because it can be bonded in a dotted manner at the intersection with the glass fiber, and the acid-soluble phase can be rapidly eluted during the acid treatment described below.

まりあった不織布の製品が得られる。The split-phase glass fiber nonwoven fabric partially fused with synthetic fibers is immersed in 0.2-6N hydrochloric acid, nitric acid or sulfuric acid,
The acid-soluble phase is eluted from the phase-separated glass fibers by heating at a temperature of 60-90°C. By such acid treatment, the phase-separated glass fiber becomes a porous glass fiber consisting of a three-dimensional skeleton mainly composed of SiO□ and pores. During acid treatment, water-soluble binders (including those attached to the pores of activated carbon fibers) during nonwoven fabric molding are redissolved in the acid solution, but because they are partially fused by the synthetic fibers, they cannot be separated. The fibers of the phase glass fiber nonwoven fabric are not redispersed. After the acid treatment, the nonwoven fabric is washed with water and dried to obtain a nonwoven fabric product in which porous glass fibers and activated carbon fibers are entangled.
