First, a web 2 of ordinary synthetic fiber (for example, 100% polyester) is placed on the feed apron 1 as a base material.
A low melting point resin adhesive sheet 3 is fed onto the surface of the stripping plate 3 from a high position along the lower end surface of the stripping plate 4, and the stripping plate 4 is overlapped and introduced into the first needle punch machine 5. First needle punch machine 5
The needle plate is arranged so that the direction of the punching felt needle 6 from the base material supply side is the top punch of the a zone and the bottom punch of the b zone, and this punch machine is used to punch the low melting point resin adhesive sheet of the laminated web into the a zone. The web is sufficiently divided into webs by the felt needles 6 of the felt needle 6, and the web and the divided low melting point resin adhesive sheet are temporarily fixed in zone b.

The fibers of the laminated web were fed to a needle punch machine 8 and subjected to a finishing punch to entangle the fibers of the laminated web. Thereafter, heat treatment is performed using a microwave heating device 9 or a heated embossing roll 10 to melt and dissolve the entire low-melting point resin adhesive sheet split into a spider web shape at the center of the laminated web, resulting in a split spider web-like sheet. 12, and the web-like sheets 12 are entangled with each other.

行われる。 The heat treatment using the microwave heating device was performed at a frequency of 915 or 2450 MHz. Furthermore, the temperature distribution of heating by microwaves is characterized in that the center part is higher in temperature than the peripheral part, and the larger the dielectric constant ε and dielectric loss angle tan δ of the object to be heated, the easier it is to be heated. Since water has large ε and tan δ, substances containing water are heated more easily. Regarding the crystallinity of synthetic fibers, tan δ increases as the crystallinity decreases. In other words, the upper and lower layers are made of polyester with high crystallinity and low moisture content. polypropylene. Polyelethane. Modaacrylic. Vinylidene chloride. The degree of crystallinity is low in the center of the web fibers, such as
Polyamide and ethylene with high moisture content. Vinyl acetate copolymer, polyethylene. ethylene. Vinyl acetate copolymer, vinyl chloride. vinyl acetate copolymer,
By using a combination of low melting point resin adhesive sheets such as polyvinyl acetate and plasticized cellulose acetate, melting and dissolution proceed steadily in the center without damaging the web fibers in the upper and lower layers. Furthermore, as a base material for needle punching, as mentioned above, a sandwich structure of a low-melting resin adhesive sheet made of a synthetic fiber web, a combination of multiple sander trenches, or a single structure of a synthetic fiber web and a low-melting resin adhesive sheet can be used. A single laminate may be used. If these punched laminated nonwoven fabrics are treated in advance with a solution that dissolves only the divided sheet of low melting point resin adhesive and then subjected to microwave heating treatment, the effect of surface dissolution of the divided sheet of low melting point resin adhesive due to the solvent and the Combined with the microwave heating effect of moisture, the solution is rapidly dissolved.

傷当て布として適している。 As shown in Fig. 2, the nonwoven fabric obtained by the above microwave heating treatment has a low melting point resin adhesive sheet in the center which is not in a sheet state but in the form of a split spider web when needle punched. Therefore, they are entangled with the fibers of the web 13, and the distribution of the split web-like sheets 12 becomes coarser toward the surface layer, and the fusion is performed in a web-like manner in two-dimensional directions.
In addition, it has a structure in which it is formed approximately at the center in the cross-sectional direction. Furthermore, by passing through the thermal calendar roll 14, the fuzz on the surface web is also set, resulting in an extremely smooth flexible nonwoven fabric. Further, instead of using the microwave heating device, the bonding process may be performed by passing through a gap between a pair of heating embossing rolls 10, which are a roll having protrusions on the surface and a flat roll. The flexible nonwoven fabrics obtained in this case are particularly suitable as disinfectant wound dressings.

On the surface of the synthetic fiber web to be supplied onto the feed apron, a low melting point resin adhesive sheet is supplied from a high position along the lower end surface of the stripping plate, and top pricking with a felt needle and then bottom pricking are performed. Then, the low melting point resin adhesive sheet is divided into spider web-like fibers and temporarily attached to the web, and then a synthetic fiber web is further stacked on the surface of the low melting point split fibers which have become the spider web shape. A method for producing a flexible nonwoven fabric, which comprises transporting the fabric to a needle punch machine (No. 2), performing a finishing needle punch to entangle the fibers, and further heat-treating with a microwave heating device or a heated embossing roll.
