Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packing string used for packing a package, and more particularly to a shape-disintegrating packing string which loses its shape and loses its strength after being discarded after use.

[0002]

[Prior 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 of mixing a synthetic resin with a photosensitizer and photodegrading the synthetic resin product, and a method of mixing starch and the like with the synthetic resin and decomposing the synthetic resin product with bacteria have been proposed.

[0003]

[Problems to be solved by the device]

 However, the photo-decomposer has a problem that the synthetic resin product remains bulky without being decomposed when the synthetic resin product is buried in the soil before use after decomposition. In addition, even if it is discarded on the ground after use, 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 incomplete.

In particular, in the field of packing strings used for packing packages, there is no solution to the above-mentioned pollution problem, it has strength suitable for packing, and it can be easily destroyed when discarded after use. Was long-awaited. In view of the present situation, the present invention aims to provide a shape-disintegrating packing string that solves the conventional problems.

[0005]

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention uses a non-woven fabric as a strength member and joins the same with a binder in which the cord easily collapses. That is, in the shape-disintegrating packing string of the present invention, a large number of child strings are aligned and joined together through a binder of water-based adhesive or emulsion adhesive, and the child strings have a fiber arrangement. On the other hand, a non-woven fabric having a weight per unit area of 15 to 50 g / m ² was cut along a fiber arrangement direction with a width of 10 to 30 mm, and was twisted by including the binder.

[0006]

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a packing string of the present invention, in which a large number of child strings 2 are aligned and joined and integrated via a binder. Generally, in the packing string 1, the child strings 2 are 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. The cord 2 is formed by cutting a non-woven fabric having a basis weight of 15 to 50 g / m ² in a width of 10 to 30 mm along the fiber arrangement direction, applying a binder described below, and twisting it. 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 50 g / m ^{2 in} terms of strength for packing. The reason for cutting the above-mentioned non-woven fabric with a width of 10 to 30 mm is to make it easier to twist, and the twisting improves the strength of the cord 2 and makes it easier to collapse the shape.

As a binder for aligning a large number of child strings 2 to form the packing string 1, it is preferable that the binder has properties such as poor water resistance, weakness to light, and decomposition by microorganisms such as bacteria. Various types 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 system such as ethylene-vinyl acetate emulsion is used. Adhesives, or those in which a photosensitizer represented by an azo compound is appropriately mixed, and the like are preferably used.

For example, a nonwoven fabric made of rayon fibers 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, and a 20% aqueous starch paste solution is applied as a binder. Then, the cord was twisted to form a cord, and the cord was 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. Further, when this packing string was exposed to the outdoors, the tensile strength after one month decreased to 20 kg, and after two months, its shape remained almost unchanged.

[0010]

[Effect of the device]

 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 bonded through the binder of the water-solvent adhesive or emulsion adhesive. Therefore, the life of the product can be set by the durability of the binder, and after use the shape will collapse due to the natural environment, and eventually it will become a single fiber and return to the soil, without polluting or destroying the natural environment.

Moreover, in the large number of cords, a nonwoven fabric having a basis weight of 15 to 50 g / m ^{2 in which} the fiber arrangement is biased in one direction is cut along the fiber arrangement direction with a width of 10 to 30 mm and twisted. Since it is made of a material, it can be made into a string having sufficient strength for packaging.
