- the needle-punch type carpet material is obtained by cutting synthetic fibers into appropriate lengths, randomly laminating them to a certain thickness, drying the binder applied to needling, forming a mat, and drying. Things.
- such needle-punch type fibers are preliminarily mixed with 5 to 20% of low-melting fiber (such as refined fiber) and then heated and pressurized after needling. In some cases, some of the fibers are welded to prevent the fibers from coming off and from fraying. More recently, the use of this type of power material The proportion is increasing.
- Any of the above-mentioned types of carpet materials requires a two-stage treatment in order to form a carpet having a three-dimensional shape.
- the back side of the forcepipe material is coated with molten polyethylene to a certain thickness, cooled to room temperature, and temporarily stocked.
- the coated material is inserted into a furnace and heated to 120 to 140 ° C to soften the polyethylene and bring it into a semi-molten state so that it has a desired three-dimensional shape.
- the mold is then pressed.
- the two steps involved in such forming are due to the inherent mismatch between the molten polyethylene coating and the timing of the press forming cycle.
- a three-dimensionally shaped carpet is formed, but usually, the felt neo is additionally bonded to a place where sound absorbing measures are required.
- the polyethylene coating on the back of the carpet material requires extrusion coating by the T-die method, which requires extensive equipment and requires a large amount of heat energy during coating.
- the polyethylene coated on the back of the carcass material has a low specific gravity and is uniformly thin, so it is extremely lightweight and convenient to handle, but it is not suitable for sound absorption, vibration suppression, heat insulation, etc. Each characteristic is very poor.

- the thickness of the space in the mold is partially increased, and the thickness of the carpet fiber structure corresponding to the increased space is increased. It is preferable to apply a foaming mixed solution thicker than the others on the back surface by a spray method.
- the carpet fiber composition is preferably made of a woven fabric, a knitted fabric, a tufted fabric, a nonwoven fabric, or a needle punch made of natural fibers, synthetic fibers, chemical fibers, or inorganic fibers. Preferably.
- the fine particles of the foamable mixed solution sprayed by the spray method enter the tissue of the carbon fiber composition and adhere to the fiber surface, while the attached foamable mixed solution immediately foams due to a gasification reaction. Because of the expansion, it stays in a shallow place inside the fiber composition and foams without substantially penetrating deeper, whereby the foam layer is integrated with the cartridge fiber composition.
- the fiber composition to which the foamable mixed solution has been applied is placed in a mold comprising an upper mold and a lower mold, and the applied foamable mixed solution is applied.
- a three-dimensionally shaped cartridge is formed.
- the foaming mixture used here is a highly reactive mixture containing a large amount of water
- the reaction proceeds due to its own reaction heat, and heat is applied from the outside during the molding of the carpet. Need not be.
- the water generated by the reaction migrates into the fibers of the force-fiber fiber composition, which facilitates the molding of the fiber composition.
- the foaming liquid mixture has a highly reactive formulation
- the foaming reaction starts immediately upon adhering to the fiber composition and expands, causing a rapid rise in viscosity.
- the foamable mixed liquid can be selectively applied to a required portion in a considerably thicker manner, and the thickness of the foam layer is partially adjusted by adjusting the space gap of the molding die (which is difficult with the conventional technology). (Up to the specified thickness).

- the whole may be applied thickly, but it is not preferable because the space between the upper mold and the lower mold is narrow because it is excessively compressed, becomes very hard, and is wasted on the material. .
- the foamable liquid mixture used here changes its state while causing a chemical reaction as shown in FIG. That is, as indicated by line 1-6 in FIG, SPRAY been mixture, the C 0 2 immediately undergo a chemical reaction It rapidly expands its volume while emitting violently, that is, foaming (foaming area).
- the viscous flow state continues after the gasification reaction has ended (rise time), as indicated by line 17. In this state, the mixture easily deforms when pressure is applied.
- tack-free a point called tack-free
- Hardening begins at 18 and eventually solidifies completely (1 9), forming a foam layer.
- the foamable mixture When the foamable mixture is heated as described above to promote the reaction, the viscosity is reduced, and the state is changed by spraying with a spray device, the uniform foam that cannot be obtained with the conventional foamable mixture is generated. It becomes fine particles 11 (Fig. 2) and undergoes a rapid chemical change (because it is pre-heated, a rapid chemical change occurs even if the temperature of the fine particles in the mixed solution drops slightly during spraying). It penetrates into the tissue constituting the carbon fiber composition and adheres to the fiber surface in the tissue. Therefore, the volume immediately expands and the viscosity increases, so that it cannot penetrate deeper than it, but it can penetrate all over the apparent part of the car- bon fiber material.
- the mixed solution When the mixed solution is applied by spraying in this manner, the mixed solution does not penetrate into the surface structure of the carcass, but becomes integral with the apparent portion on the back surface of the carbon fiber composition. Then, when the mixture is cured, the fiber material of the car- tridge is firmly held, and is prevented from fraying and coming off (in this way, the mixture is applied to the surface of the car- ber fiber composition. Do not pass In addition, the place where the fiber material of the carpet enters to such an extent as to prevent it from fraying or coming off is defined as a shallow place inside the carpet fiber composition.
- the foam fiber mixture 13 to which the foamable liquid mixture 15 has been applied is used.
- the mold is placed in the upper mold 21 and the lower mold 22 of the mold 20, and when the foamable mixed solution 15 is in a viscous flow state, both molds are closed and pressurized to form the mold. Tighten (Fig. 6).
- mold clamping is about 50-70 seconds after spraying. At this time, the foamable mixture is compressed and deformed along the mold.
- the upper mold 21 and the lower mold 22 of the molding die 20 are designed so that when they are closed, a space gap corresponding to the desired shape of the cartridge is formed therebetween (see FIG. 6). That is, as shown in Fig. 1, the thickness of the space gap is large where the sound absorbing part 3 is formed (30, 31), and the thickness of the space gap is small where the central raised part 4 is formed. In this way (designated by reference numeral 32), the surface shape of the mold is designed.
- the foam is hard where the space is narrow, and soft and elastic over a wide space.
- the mold clamping is maintained for a predetermined period (about 60 seconds in this embodiment) (FIG. 6). Then, after the curing is completed 90% or more, the pressure is released, and a force unit with a stable dimension is taken out.
- the upper and lower dies of the molding die can be used upside down. However, in this case, the back surface of the sprayed cartridge fiber composition is arranged so as to be in contact with the surface of the mold having a shape corresponding to the designated floor.
- a carpet having a sharp three-dimensional shape faithfully following the space gap in the molding die is manufactured.
- the foam layer enters into the carpet fiber composition and is integrated, so that the shape of the carpet is maintained. Further, the foam layer firmly holds the fibers of the cartridge fiber composition and prevents the fibers from coming off. Therefore, the back coating, which was essential in the conventional technology, is not required.
- the thickness (including the partial thickness) of the foam layer formed by the foamable mixed solution, the space gap in the mold, and the foamable mixed solution applied on the cardboard fiber composition Since the thickness can be adjusted arbitrarily by the application thickness, it has become possible to form a foam having a thickness of 10 to 50 mm, which was difficult in the past.
- the foam layer should be thicker (or thinner)
- adjust the gaps in the mold and the places where the foamable liquid mixture is applied thicker (or thinner) on the cardboard fiber composition can be determined conveniently.
- the elasticity of the foam layer can be adjusted as well.
- the foam layer on the back surface of the carbon fiber composition formed in accordance with the present invention is formed by applying a foamable mixed solution by spraying and clamping with a molding die, the conventional technology has an advantage. There is no need to perform the backside treatment twice, in which a large amount of heat is applied from the outside of the carpet, and therefore, there is no curl or uneven appearance of the carpet caused by the backside treatment. We can produce quality carpets.
- the fine particles enter the fibers inside the tissue of the fiber composition of the carpet, so that the foam layer and the foam layer formed from the mixture are forced to work.
- the pet fiber composition forms a body and prevents the fibers from fraying and the pile from coming off after the tufting of the loops. Therefore, it is indispensable in the prior art to prevent the fiber from coming off. No need for back coating. Further, since the sprayed foamable mixed solution stays in the apparent area on the back surface of the carpet fiber composition and does not bleed on the surface, the fibers of the carpet do not become hard, and It is possible to produce a tactile force piece.
- the application amount of the foamable mixed solution can be partially changed, it can be combined with a partial change of the space gap in the mold to obtain a desired thickness at a desired place.
- Carpets can be manufactured for surfaces. Therefore, unlike the prior art, the foam layer appropriately formed does not need to separately form an additional material for providing vibration damping, sound absorption, and heat insulation. A carpet having good heat insulating properties can be manufactured.
