However, in practical use, different users may have different demands on the hardness, softness and air permeability of the fiber mat.
With only a single property parameter for the same fiber mat, the fiber mat can only meet the needs of one user.
If we want to meet the needs of different users, we need to produce multiple types of products with different property parameters.

For example, when the fiber mat includes the third fiber layer 103, the third fiber layer 103 is composed of the third three-dimensional crimped fibers and the third three-dimensional crimped fibers. The cross section of the first three-dimensional crimped fiber and the third three-dimensional crimped fiber is solid, and the cross section of the second three-dimensional crimped fiber is hollow. If the cross section of the three-dimensional crimped fiber is hollow and stiff, it can guarantee the bearing capacity, and if it is solid and flexible, it can guarantee the comfort, thereby: In addition to ensuring the air permeability of the fiber mat, it can be ensured that the fiber mat has sufficient bearing capacity.

In S001, the raw materials are mixed and then stirred under normal temperature conditions.
In the actual use process, after the raw materials are mixed, they are stirred for 10-40 minutes to form a mixture.

In S002, the mixture enters the dryer in a vacuum manner, and the temperature and drying time of the dryer are adjusted according to the type of material of the mixture.

The water tank can be further installed with a circulation device to ensure a uniform and constant water temperature.

In S007, guide rollers guide the movement of the fiber layer in the water tank, and pulling rollers 5 pull the fiber layer out to the surface of the water.
The fiber layer is pulled out to the surface of the water by the action of the active pulling roller outside the water tank, and a guide roller is installed in the cooling water tank along the direction of movement of the entangled yarn layer to pull it out due to the excessive buoyancy of the water. Deformation problems can be avoided.

In S008, the fiber layer is cut according to actual needs, and after cutting, it is set in a wind drying box along the direction of production to be blown dry.

In S009, after the fiber layer is dried, the fiber layer is heat-pressed (formed into a certain shape) in a mold according to the shape of the product.
During actual use, the temperature range for hot pressing is 80° C. to 130° C., and the time range for hot pressing is 5 minutes to 30 minutes.

The present invention provides a fiber mat manufacturing machine for realizing the above fiber mat manufacturing method, as shown in FIG. , transport rollers 4 , traction rollers 5 , guide rollers 6 , dryer 7 and transport screws 8 .

The water tank 3 is for storing cooling water, and the conveying rollers 4 are provided in the water tank 3 so as to be completely immersed in the cooling water of the water tank 3. The conveying rollers 4 are immersed in the cooling water. This is for ensuring molding of the fiber layer by adjusting the moving direction of the fiber layer in the cooling water.
The yarn jetting assembly 1 is located outside the water tank 3 , the water spray plate 2 is installed obliquely between the yarn jetting assembly 1 and the transport roller 4 , and the first end of the water spray plate 2 faces the transport roller 4 . one end close to the water surface, the second end of the water spray plate 2 extends toward the yarn ejection assembly 1, the water spray slope of the water spray plate 2 faces the yarn ejection surface of the yarn ejection assembly 1, and the fiber layer is extruded from the yarn ejection assembly 1, it falls vertically on the water spray plate 2 and the water surface, and the cooling water on the water spray plate 2 first contacts the fiber layer and cools the fiber layer first. can be done.

As shown in FIG. 6 , the water spray plate 2 includes a water reservoir 21 and a water spray slope 22 , the water reservoir 21 is connected to the second end of the water spray plate, and the water reservoir 21 is provided with a water spray hole 211 . The water storage chamber 21 is for storing cooling water, and the cooling water falls into the water tank 3 via the water spraying slope 22 via the water spraying hole 211 , and the water spraying hole 211 of the water storage chamber 21 in the water spray plate 2 . is located above the watering slope 22, the main advantage is to reduce the distance between the thread ejection plate and the cooling water, and the fiber layer when falling on the watering plate 2 or the water surface. The temperature can be increased to ensure bond fastness between the contact points of adjacent fibrous layers.

As shown in FIG. 4 , the water tank 3 is provided with a plurality of guide rollers 6 , and the fiber layer after cooling is passed from the water tank 3 to the outside of the water tank 3 via conveying rollers 4 . A pulling roller 5 is provided for drawing out, and a plurality of guide rollers 6 are arranged in order along the direction in which the fiber layer moves from one end of the conveying roller 4 farther from the water surface to the pulling roller 5 .
The guide roller 6 can solve the deformation problem caused by the non-uniformity of water buoyancy to the fiber layer.
Specifically, in the actual production process, the density of the production raw material is between 0.85 and 1.1 kg/m ³ , and due to the large porosity of the fiber layer structure, its overall density is higher than Small and subject to upward buoyancy.
Therefore, by adding self-rotating or non-rotating guide rollers 6, the effect of upward buoyancy on the fiber layer can be avoided.

As shown in FIG. 7, the watering slope 22 of the watering plate 2 includes a first slope 221, a second slope 222 and a third slope 223 connected in order in the direction closer to the conveying roller 4. The rate increases in order.
The function of the first slope 221, as a receiving plane for the water coming out of the watering hole, is to ensure that the water spray forms a uniform water flow layer on the second slope 222, and the surface fibers due to the water layer unevenness. It is possible to avoid the problem of unevenness due to the difference in cooling rate of the layers.
The action of the second bevel 222 is to crimp the fibers ejected from the thread ejection assembly 1 to form three-dimensional crimped fibers by entangling, bonding and contacting the fibers, while the action of the third bevel 223 is to The function is to increase the contact and bonding time between the three-dimensional crimped fibers to avoid premature entry into the cooling water when the three-dimensional crimped fibers are not firmly bonded, This avoids the problem that the contact points between the three-dimensional crimped fibers are cooled under too short a contact time, resulting in a poor adhesion effect, and improves the mechanical performance of the fiber mat.

Specifically, compared with the normal water spray plate 2, in the present invention, the length of the third slope 223 in the water spray plate 2 is increased, and the length of the third slope 223 is extended, so that the yarn is spouted by the circulating water. The flow of circulating water on the sprinkling plate 2 is delayed so that the surface water temperature directly under the plate does not change rapidly, and the temperature difference of the water temperature directly under the thread ejection plate is guaranteed, so that the water surface layer with a high temperature is maintained. The problem is that when the fiber layer is dropped into water and rapidly cooled and fixed in shape, the adhesion effect at the contact point between the three-dimensional crimped fibers is deteriorated by extending the bonding time of the fiber layer. resolved.
