。No. 2 That is, the method of the present invention uses variable natural fibers, synthetic fibers, or other recycled cotton, or pulp fiber materials obtained from plants.
A suitable amount of cotton, etc. is mixed to form an integrated fiber layer, and during transportation, particles of heat-fusible resin are sprinkled and the fibers are finely opened by a spreading mechanism to form a laminate that uniformly entangles the blended powder fibers. The resin particles are supplemented and scattered from above, and the fiber laminate is vibrated by a vibration mechanism, causing the resin particles to jump and infiltrate and adhere to the wrapped fibers, while being transferred into a heating furnace and hot air is convected. The resin is thermally fused and entangled with the permeable fibers, and further pressed into a high-temperature furnace to strengthen the heat solidification, followed by a pair of upper and lower hot press flat finishing rollers or a hot press with arbitrary engravings such as unevenness. Since the fibers are extracted by being inserted between rollers, even if the fibers are a rough mixture of different types on the inside, the single fibers are wrapped on the outside and are integrally formed by hot-melting, curing, and entangling, so they can be separated and peeled off. This method is characterized by continuously manufacturing a laminated fiber structure having a uniform appearance and shape.

Detailed Description of the Invention The present invention provides a method for continuously manufacturing a structure in which the inner and outer fiber layers of a fiber laminate having different materials and colors are collectively heat-fused, entangled, and hardened with a resin. It is related to. Conventionally, felt made by adding resin to fibers and molding them through heat fusion and curing in a heating furnace, or hard plates made by heat pressing, are easy to use because the color tone and material of the fiber base material, which is spread and blended, is directly expressed in the molded product. When blending fibers or hybrid fibers, the appearance of the product is not unified, so in order to avoid a feeling of inferiority, it is necessary to attach a single material such as woven or non-woven fabric, or to improve the appearance by additional processing such as dyeing. A method was adopted to unify the The present invention is a manufacturing method aimed at improving the above-mentioned drawbacks of the conventional method, in which an appropriate amount of natural fibers, synthetic fibers, recycled cotton such as synthetic fibers, pulp fibers obtained from plants, cotton, etc. are blended to form an integrated fiber layer. While transporting, fine particles of thermofusible resin are sprinkled and opened finely by opening mechanism No. 2, and the blended powder fibers are uniformly mixed into a laminate and transported, and the laminate is transported from top to bottom and outside. Each layer surface is coated and polymerized with a different single quality fiber to form a multi-layer, and the heat-fusible resin particles are supplemented and sprinkled from the nigga,
A vibrating mechanism vibrates the fiber multilayer laminate to cause resin particles to jump in and prevent the resin from adhering to the coated fiber layer, while transferring it into a heating furnace to allow hot air to pass through by convection, thereby hot-melting and fusing the resin to the fibers. The lower pair of heat-pressing flat rollers,
Alternatively, it can be produced by inserting it between heated rollers having an appropriate engraved pattern such as unevenness, and subjecting it to heat-fusion hardening molding. Therefore, even if the inside is a coarse mixture of fibers, the outer surface is coated with a single-shaped fine fiber and is thermally fused and entangled, so it does not separate and peel off and has a uniform appearance and shape. This is a method for manufacturing structures continuously. The manufacturing method of the present invention will be explained in more detail based on the apparatus of the embodiment shown in FIG. No. 3 Fiber layer 1, which is made by blending and accumulating appropriate amounts of miscellaneous fibers such as natural fibers, synthetic fibers, or recycled cotton of varying types, valve fibers obtained from plants, cotton, etc., is thermally melted during transportation. Fine resin particles 2 are spread, the fibers are finely opened by the opening mechanism 3, and the mixed fibers and resin are uniformly mixed and conveyed as a laminate 4. Separate single-shaped resin particles are placed on the upper and lower tiers of the laminate 4. Slightly high-quality fibers 56 are arranged in a wrap-like manner, and while the laminate 4 is being transferred, mono-slightly high-quality fibers 5.6 are polymerized and coated on the upper and lower outer layer surfaces to form a multi-layer laminate 7. The same kind of resin particles 2' are supplemented and spread, and the fiber multilayer laminate 7 is vibrated by the vibration mechanism 8 to cause the resin particles 2.2' to jump and mix in, and to adhere to the coated fibers 5.6 while being heated in the heating furnace 9. The heated air is passed through convection with the blower 10, the fibers are subjected to heat fusion softening and subsequent treatment, and further, the fibers are guided under pressure to the compressor 12 in the high-temperature furnace 11 to intensify heat curing, and then A hardened fiber body 15 is inserted between a pair of upper and lower pressurized flat heat rollers 13 and 14 installed later, or upper and lower rollers formed by engraving an appropriate shape on the surface of the heat rollers, and hot pressure molding 1G is performed. It is produced by Therefore, as shown in Fig. 2, the product produced by pressure molding using the pressurized flat heat rollers 13 and 14 has a laminate 4 of short fibers fused together with the covered single high-quality fiber 5 and 6 using resin. The cured fiber body 15 is a flat and flat product made of entangled cured fiber bodies 15, and the cured fiber body 15 which is inserted and pressure-welded between heat rollers 13 and 14 whose surfaces are engraved with irregularities has a side surface as shown in FIG. The concavo-convex patterns 17 and 18 are pressed to produce a structure of the molded body J6. Alternatively, as illustrated in FIG.
, a tooth shape, or a double-sided tooth shape 20, etc., to obtain a solid structure 16. The manufacturing method of the present invention configured as described in -J- has many excellent effects as follows. K) Utilizing a wide variety of new and old waste cotton and waste fibers of poor quality, or short fibers with poor elasticity and tension and no entanglement, or new and old fibers such as pulp and cotton obtained from plants. The outer corner of the blended cotton aggregate is coated with single-shaped, fine-quality fibers and then heat-sealed and entangled with resin to form the product, and the interior has a rough, different color and no tension. Even in the fiber body, the outer layer is covered with high-quality fibers and the inside is integrally fused and entangled with resin, making it a highly durable composite structure without peeling or separation.Also, it is a high-quality composite structure that has a uniform appearance even though it is made of inexpensive materials. By adjusting the heat and pressure adjustment of this manufacturing process, versatile products such as felt-like or robust hard plates having flexibility and elasticity can be obtained. Therefore, it can be used as a flexible and elastic felt beam, cushioning material for cushioning materials, or as a sound-absorbing and heat-insulating base material, making it ideal for use as interior materials for automobiles and other building materials. In addition, the hard plate formed by high-pressure thermosetting is suitable as a building material for indoor and exterior installations such as ceiling boards and wall boards. (2) When heat-sealing and entangling resin all at once with miscellaneous fibers inside and high-quality fibers on the outside, the laminated fiber structure formed into a wave shape, tooth shape, or double-sided tooth shape is flexible in bending. As a molded corrugated sheet that has superior resilience and elasticity, it is suitable for use as a corrugated sheet material, or as a core substrate material for corrugated board boards that require elasticity and cushioning properties. As described above, the manufacturing method of the present invention can produce excellent elastic felt or strong fiber hard board by covering coarse and inexpensive fibers with high-quality fibers and thermally fusing resin all at once. It has many excellent features, such as being able to economically produce structures of uniform quality continuously through simple processes and providing them at low cost.
