造方法を提供しようとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a nonwoven fabric molded article. More specifically, the present invention aims to provide a novel method for manufacturing a nonwoven fabric molded article that enables extremely deep drawing processing with an area ratio of 200% or more.

はり、きわめて油水分離性能の良いフイルター材
となる。 There are various cases where deep drawing is required. For example, conventional ventilation fan filters are made of mesh, woven or non-woven fabric fixed with a wire mesh or plastic frame, but these have poor ventilation effects due to their small exhaust area, and the surrounding area is It is easy to get dirty, and there are also problems such as placing too much load on the ventilation fan motor. In such a case, if a nonwoven fabric is deep drawn and used as a deep filter material, it is possible to obtain a material with a wide ventilation area and low pressure loss. Furthermore, if an oil/water separation filter or the like is obtained by deep drawing a nonwoven fabric, the filter material will have extremely good oil/water separation performance.

適なものしか得られなかつた。 In this way, if a filter material is obtained by deep drawing a nonwoven fabric, it is possible to obtain an extremely good filter material for use in air conditioning or oil/water separation. When molding was attempted, some of the entanglements were unraveled, the constituent fibers were cut, or the fibers were extremely dense, making it unsuitable for use as a filter material.
本発明は以上のような状況に鑑み為されたもの

ことを特徴とする。 The present invention has been developed in view of the above-mentioned circumstances, and it is possible to perform very deep drawing forming with an area ratio of 200% or more, and also to prevent the occurrence of extreme density and density in the structure even after forming. The aim is to provide a novel method for producing a nonwoven fabric molded article, which involves needling a fiber web containing at least 10% (by weight) of fibers with a cutting elongation of 100% or more at a temperature of 150°C below the melting point. It is characterized in that it is made into a fiber felt, which is preheated at a temperature of 150°C below the melting point or higher, and then drawn and formed to have an area ratio of 200% or more.

乗じたものである。 The cutting elongation here is the difference between the length of the fiber when it is cut and the original length, divided by the original length, and the quotient is multiplied by 100. The area after the molding process is divided by the area before the molding process, and the quotient is multiplied by 100.

It is necessary to be present. There are several commercially available fibers that have a cutting elongation of 100% or more at a temperature of 150°C below the melting point. For example, Kanekalon H.

A fibrous web containing at least 10% (by weight) of fibers is prepared, and what is contained in this fibrous web is further selected depending on the use of the final nonwoven fabric molded article. For example, when trying to obtain a filter material for air conditioning, it is desirable to contain 30% or more (by weight) of flame-retardant thermoplastic fibers. For example, when an oil/water separation filter material is to be obtained, it is preferable to contain at least 20% (by weight) of thermoplastic fibers having excellent oil resistance.

繊維フエルトを得るようにすると良い。 The fiber web containing the above fibers is opened and stacked to form a sheet, and then the needle density is 10/cm 2 - 300.
Needling is performed in the range of fibers/cm 2 so that the constituent fibers are arranged three-dimensionally in the thickness direction of the sheet to obtain a fiber felt. If it is necessary to increase the shape retention of the resulting fiber felt, the entangled nonwoven fabric may be spray impregnated, roll impregnated or sprinkled with a thermoplastic adhesive emulsion or powder, thereby adhering the constituent fibers. It is preferable to obtain a fiber felt that has moldability.

過性能が更に良くなる。 In addition, in the above needling, when trying to obtain air conditioning filter material, the needle density is 10 needles/ cm2 to 100 needles.
It is preferable to carry out the needle density in the range of needles/ cm2 , and when trying to obtain oil/water separation filter material, the needle density is 15.
It is preferable to carry out in the range of 300 lines/cm 2 to 300 lines/cm 2 .
In addition, when obtaining an oil-water separation filter material, it has a density gradient such that it is sparse on the inner side of the bottomed cylinder (1 in Figure 1) and denser on the outer side (2 in Figure 1). By doing so, the overperformance will be further improved when used as a filter material.

For example, when used as a filter material for air conditioning, a flame-retardant thermoplastic emulsion, an adhesive emulsion or powder made by adding a flame retardant to a synthetic resin, etc. are used, and when used as a filter material for oil/water separation, For example, a resin having excellent oil resistance, such as a chloroprene resin, an acrylonitrile resin, a urethane resin, or an acrylic resin, is used.

It is a good idea to apply a water-repellent treatment to the fiber felt that has excellent oil resistance. Examples of such water repellent treatment agents include futsuso-based,
A water repellent such as a silicone-based water repellent is suitable, and preferably a melamine crosslinking method is used. When the filter 3 is made into a cylindrical shape with a bottom as shown in Fig. 2 by applying water-repellent treatment, the oil in the oil-water passes through the filter 3, the water adheres to the inner wall surface or accumulates inside, and only the oil remains in the filter. It will be done. If you want to further improve the accuracy of oil/water separation, add a water absorbing agent (hydrophilic agent or hydrophilic fiber) between inner layer 1 and outer layer 2.
It is better to fill the inner layer 1 with water-absorbing agent or to apply a transparent cloth treatment to the surface of the inner layer 1.

Preheat at a temperature within the range of 0 to 150℃ below the melting point of 100% or more fibers, then vacuum or pressure mold using a mold with a specified mold so that the area ratio is 200% or more. A nonwoven fabric molded body is obtained by deep drawing molding.

として好適である。 According to the method of the present invention, as explained above,
The fiber felt before forming contains at least 10% (by weight) of fibers with a cutting elongation of 100% or more at a temperature of 150°C below the melting point, and these are entangled by needling, so deep drawing is not possible. Even when molded, the fibers do not become untangled or cut, and the elongation effect is extremely large. Therefore, according to the method of the present invention, deep drawing processing with an area ratio of 200% or more is possible, and it is suitable as a method for obtaining various filters and other nonwoven fabric molded articles.

あつた。Example 2 A fiber web consisting of 50 parts of undrawn polyester fiber 1.5d/51mm ("Tetron T-211" manufactured by Toray Industries, Inc.), 20 parts of polyacrylonitrile fiber 4d/51mm, and 30 parts of polyamide fiber 3d/51mm was loaded with a needle density of 100. / cm2 to obtain a punched felt with a weight of 500g/ m2 , and a fiber/resin ratio of 60/cm2.
After impregnating the fibers with chloroprene latex to a coating weight of 40 g/m 2 and adhering the fibers, a water-repellent treatment was applied with a melamine-based water repellent containing a melamine cross-linking agent to a coating weight of 8 g/m 2 . The obtained nonwoven fabric was heated to 130℃ for 3
The mixture was preheated for seconds, and then pressure molded using a cylindrical mold with concavo-convex molds to obtain a deep-drawn nonwoven fabric molded body. This nonwoven fabric molded body is a suitable water-repellent cylindrical molded body. When this molded body was passed through an oil-water mixture containing 10%, an oil containing almost no water was obtained. I tried making a molded body that was otherwise identical but was not subjected to water repellent treatment, but it was difficult to separate the oil and water.
