Traditionally, Volip 0
It is known that a fibrous molded article with improved water resistance, dimensional stability, moldability, etc. can be obtained by mixing thermoplastic fibers such as polyethylene fibers and polyethylene fibers and dehydrating and molding the mixture into a desired shape.

However, according to this method, synthetic resin fibers, which are different types of fibers, are mixed with plant fibers to make paper.
The bonding force due to the intertwining of the fibers is not sufficient, and therefore only a bulky (and brittle) molded product can be obtained.

In addition, in order to compensate for the lack of bonding strength due to such intertwining of fibers, it is conceivable to mix powdered or liquid synthetic resin vigitator and an appropriate fixing agent with the slurry to form paper. In addition, it is necessary to select the type of vigitator and the type and amount of fixing agent each time depending on the type of synthetic resin fibers to be mixed and the amount of mixed synthetic resin fibers, making it troublesome to adjust the slurry and causing the vigitator to flow out into the white water. Furthermore, powdered or granular vigittar is significantly adsorbed to the well-entangled plant fibers, making it difficult to expect much effect in bonding the synthetic resin fibers together.

On the other hand, since the fibrous molded body mixed with such synthetic resin fibers has good moldability, it is first formed into a board or mat shape and dried, then heated between molds heated to high temperature. Pressing and drawing are also carried out, but since the bonding force between fibers is weak when molded into a thin board-like material or a mat-like material with low specific gravity, the mat or board-like material is used when transferring between molds. Care must be taken when handling the product to prevent its body from being destroyed, which poses a problem in that work efficiency decreases.

The present invention was made in view of these problems, and provides a vegetable fiber that can obtain a desired bonding strength depending on the amount of synthetic resin fiber added without using a special vigitator or fixing agent.

Next, an appropriate amount of short fibers in the form of a flocculent body was added to a plant fiber slurry, and the flocculent body and the vegetable fibers were caused to become entangled, and then dehydrated and molded using an appropriate paper-making device. Afterwards, the molded body is dried in a state in which it retains moisture.
Alternatively, by heating between the hot plates of a net press to melt the synthetic resin binder that binds the thermoplastic synthetic resin &1# cane, the synthetic resin can also be applied to the intertwined portions of the vegetable fibers and synthetic resin fibers. A binder is infiltrated to form a fibrous molded body with excellent strength and strong bonding force between W1 fibers.

In addition, polyvinyl alcohol is generally known as a synthetic resin binder that is soluble in warm water;
It does not dissolve in water at a temperature of around 14°C, but it does dissolve in heated warm water (around 14°C).
In the plant fiber slurry, the synthetic resin fibers are held in a state of being bonded to a porous lump-like flocculent body, and do not dissolve into white water. Most of the binder added therein is present in the molded body, resulting in a good yield.

As shown in the figure, the flocculent body thus obtained has a porous three-dimensional structure in which the thermoplastic synthetic resin fibers (1) are partially bonded with a hot water-soluble synthetic resin binder (2). The fiber mass (4) is an accumulation of fiber masses (4) having a porous three-dimensional structure. .5-15
The fibers are broken into short fibers of about Plant fibers such as fibers are easily entangled (this increases the bonding strength between the fibers and improves the bending strength of the molded product.Furthermore, the binder is used together with the thermoplastic synthetic resin fibers to form a flocculent material. Since it is added to the mixture at the same time in a mixed state, it is simply added at the desired ratio depending on the amount of synthetic resin fiber added, and even when a large amount of synthetic resin fiber is mixed, it is added separately. This eliminates the need to add a special binder and exhibits a binding effect according to the amount of the flocculent mixed in.

Incidentally, such a silk-like body is formed by forming a non-woven fabric with the fibrous material of the thermoplastic synthetic resin, and impregnating this non-woven fabric with a warm water-soluble synthetic resin binder such as polyvinyl alcohol and solidifying it. By pulverizing the fibrous sheet using a Batfui'Jj or cardigator, etc., a floc-like body of porous short fibers can be obtained. Waste from the buffing process (commonly known as puff powder) used to give a suede-like finish
Considering the current situation where most of these scraps are unavoidably incinerated as it is difficult to reuse them, this will enable the effective use of industrial waste and provide inexpensive products. It is possible. Furthermore, the synthetic leather uses fibrillated thin thermoplastic synthetic resin fibers to obtain its softness, so the waste obtained by buffing treatment tends to become cotton-like and is also less likely to become entangled with vegetable fibers. It will be good.

Although the ratio of the synthetic resin fibers and the binder constituting the cotton-like body is not particularly limited, by adjusting the mixing ratio of 40 to 90:10 to 60 by weight, it is possible to increase the voids in the silk-like body. It is preferable because it improves entanglement with plant fibers and also increases the bonding effect due to melting.

Furthermore, the amount of silk material added to the plant fiber slurry in m is not particularly limited, but the dimensional stability, water resistance,
From the viewpoint of moldability and the like, it is preferable to mix 5% or more by weight of the plant fibers. There is no particular upper limit to the amount of mixed material, but for products that require strength such as building boards, the amount of cotton mixed in should be kept at 40% or less by weight of the plant fibers. It is desirable to keep
By setting this range, the hydrogen bonding and bonding strength of plant fibers can be fully demonstrated, but on the other hand, cushioning properties and flexibility are required, such as cushioning materials for packaging. For some products, it is required to add more than this.

In addition, when adding and mixing the flocculent material into the slurry, it may be added while beating with a shaker etc. to ensure good dispersion of the flocculent material. If the body is completely destroyed and the synthetic fibers are separated, the effects of the present invention cannot be obtained, so it is preferable to perform strong beating to completely destroy the bonds of the short fibers that make up the flocculent body. do not have.

At this time, there is still a large amount of water present in the molded base, and when heated as described above in the presence of this water, the polyvinyl alcohol in the floc mixed with the vegetable fibers is removed. The water melts as the temperature rises, and as the water moves, it generates fluidity and acts on the intertwined parts of the flocculent and plant fibers, increasing the binding force of the fibers and increasing their strength and strength. An excellent molded body is formed.
