[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing string used for packing packages, and more particularly to a shape-disintegrating packing string which loses its shape and loses its strength after being discarded after use.

[0002]

2. Description of the Related Art In recent years, used and discarded synthetic resin products have become a pollution problem because they pollute and destroy the natural environment. As measures against this, for example, a method in which a photosensitizer is mixed with a synthetic resin to photolyze a synthetic resin product, or a method in which starch or the like is mixed with a synthetic resin and the synthetic resin product is decomposed by bacteria is proposed.

[0003]

However, the photo-decomposable one has a problem that the synthetic resin product does not decompose and remains bulky when the synthetic resin product is embedded in the soil after use before the decomposition. . In addition, even if it is discarded on the ground after use, there is a problem that the behavior of deterioration differs greatly between the sun and shade. What is decomposed by bacteria is decomposed when the synthetic resin product is embedded in the soil after use, but its effect is still insufficient and it is in a state of incompleteness.

In particular, in the field of packing strings used for packing packages, there has been no solution to the above pollution problem, it has strength suitable for packing, and it can easily collapse when discarded after use. Was long-awaited. The present invention has been made in view of the above circumstances, and an object thereof is to provide a shape-disintegrating packing string that solves the conventional problems.

[0005]

In order to solve the above problems, the present invention uses a non-woven fabric as a strength member, which is joined by using a binder in which the cord easily collapses in shape. That is, in the shape-disintegrating packing string of the present invention, a large number of child strings are aligned and joined through a binder of an adhesive agent using water as a solvent or an emulsion adhesive, and the child strings have a single fiber arrangement. Biasing amount biased to 15 to 50 g / m
The non-woven fabric of No. ² is cut into a width of 10 to 30 mm along the fiber arrangement direction and twisted by including the binder.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. In the drawings, 1 is a packing string of the present invention,
A large number of child strings 2 are aligned and joined and integrated via a binder. In general, the packing cord 1 has the cords 2 bundled in a band shape, but may be bundled in a rope shape or the like.

The cord 2 is formed of a non-woven fabric whose fiber arrangement is biased in one direction, that is, in the manufacturing direction. This child string 2 is
Nonwoven fabric with a basis weight of 15 to 50 g / m ² is 10 to 30 mm
Is cut along the fiber arrangement direction, and the binder described below is applied and twisted. The non-woven fabric is made of synthetic fibers such as polyethylene, polypropylene and polyester, and cellulosic fibers such as rayon, linter and pulp, and has a basis weight of 15 to 5 in terms of strength for packing.
It is set to 0 g / m ² . In addition, the above non-woven fabric is 10 to 3
The reason for cutting with a width of 0 mm is to make it easier to apply twist, and by applying the twist, the strength of the substring 2 is improved and the shape is easily collapsed.

As a binder for forming a packing string 1 by aligning a large number of child strings 2, it has poor water resistance, is weak against light,
A substance having a property of being decomposed by microorganisms such as bacteria is preferable, and various substances such as liquid, powder and fibrous can be used. This binder determines the life of the packing string 1 as a product depending on its durability. For example, an aqueous polyvinyl alcohol solution, an aqueous solution of partially acetylated polyvinyl alcohol, starch paste, or an emulsion-based adhesive such as ethylene-vinyl acetate emulsion. An agent or a mixture of these and a photosensitizer represented by an azo compound is suitably used.

For example, a non-woven fabric made of rayon fiber having a basis weight of 15 g / m ^{2 in which} the fiber arrangement is biased in one direction is cut along the fiber arrangement direction with a width of 18 mm, a 20% aqueous starch paste solution is applied as a binder, and then twisted. A cord was applied to the cords, and the cords were aligned in seven strips and dried to obtain a packing cord having a width of 15 mm and a thickness of 1.5 mm. The tensile strength of this packing string was 100 kg. In addition, when this packing string was exposed to the outdoors, the tensile strength after one month dropped to 20 kg, and
After almost a month, the shape remained almost unchanged.

[0010]

As described above in detail, in the shape-disintegrating packing string of the present invention, the child string made of the non-woven fabric in which the fiber arrangement is biased in one direction is a binder of water-solvent adhesive or emulsion adhesive. Since it is bonded via the binder, the life of the product can be set by the durability of the binder, the adhesive strength of the binder is rapidly lost due to the natural environment after use, the packing string collapses in shape, and finally it becomes a single fiber. Return to the soil and do not pollute or destroy the natural environment.

Moreover, in the case of a large number of cords, the nonwoven fabric having a basis weight of 15 to 50 g / m ^{2 with} the fiber arrangement biased in one direction is 10
Since it is cut in a width of 30 mm along the fiber arrangement direction and twisted, it is possible to freely adjust the strength by aligning a large number of the child cords to form a packing cord. It can be a string having a strength enough to endure.
