Description

  The present invention relates to a molded article for preventing birds and beasts intended to prevent damage caused by invasion of birds such as crows and pigeons and animals such as dogs and cats.

Traditionally, garbage dumps in residential and industrial areas, verandas in condominiums, and farmland such as fields and orchards have been damaged by the invasion of birds such as crows and pigeons, and animals such as dogs and cats. It is a problem.
For example, garbage collection sites have problems such as scattering of trash caused by the invasion of birds and beasts such as crows, cats, and dogs, and environmental pollution caused by them. Damage caused by parasites has become a social problem. Furthermore, in farmland such as fields and orchards, birds pick up the seeds just after sowing or pick up the crops just before harvesting to hinder the growth of crops, reduce their commercial value, and lettuce, Farmers who cultivate eggplants, etc. have been damaged by wild birds stopping on the roof of the house and breaking their plastic sheets with their claws.

  Conventionally, in order to prevent damage to these crops due to the invasion of birds and beasts, the eyeball-like bird chasing tool colored in black, red, yellow, etc. is hung on the rope or the eaves of the building to drive away the birds and animals Has been proposed (Patent Document 1). It has also been proposed to protect the grains and fruits while threatening birds and beasts by covering the grains and fruits of the fields with a light-reflective net that is knitted and knitted with light-reflective gold and silver knitting yarn members ( Patent Document 2).

  However, none of the methods for driving away wildlife and protecting agricultural products from birds as described above was effective when the wildlife was used, and was not an effective means for extermination of wildlife. In addition, gold and silver tapes and strips were sometimes hung on a rope so as to flutter in the wind, but this alone was not effective for chasing birds and beasts.

The present invention has been made in order to solve the above-mentioned conventional problems, and the first problem is to radiate strong stimulating light by irradiating with sunlight and to reliably and effectively protect birds and beasts. An object of the present invention is to provide a bird and beast prevention molded body that can be controlled.
Furthermore, the second object of the present invention is to provide a molded product for preventing birds and beasts that can control birds and beasts for a long time by emitting strong stimulating light by irradiation with sunlight.

  As a result of intensive studies to solve the above problems, the present inventor is composed of at least a thermoplastic resin and a fluorescent dye, and the blending ratio of the fluorescent dye to the thermoplastic resin is 0.001 to 2 weights. % Of the molded product for the prevention of birds and beasts is found to emit light that is a strong stimulus to birds and beasts when irradiated with sunlight, and a fluorescent dye is attached to the surface of the molded product made of thermoplastic resin. The present invention has also been found by finding that the same effect is exhibited in a molded product for prevention of birds and animals characterized by the above.

  The molded object for prevention of birds and animals of the first aspect of the present invention comprises at least a thermoplastic resin and a fluorescent dye, and the blending ratio of the fluorescent dye to the thermoplastic resin is 0.001 to 2.0% by weight. The radiant light generated by irradiating is stimulated to the eyes of birds and animals and has an effective control effect on birds and animals.

  In particular, when a red color is selected as the emitted light, it is preferable to use a fluorescent dye that absorbs light in a wavelength region of less than 400 to 600 nm and emits light in a wavelength region of 600 to 700 nm. Red sharp light is emitted, and it is possible to give birds and animals a strong stimulus several times, for example, three times or more, compared with ordinary red pigments.

According to a second aspect of the present invention, a surface of a molded body made of a thermoplastic resin is attached with a fluorescent dye that absorbs light in a wavelength region of less than 400 to 600 nm and emits light in a wavelength region of 500 to 700 nm. A molded product for prevention of birds and animals characterized in that, when irradiated with sunlight, the fluorescent dye attached to the molded product for prevention of birds and animals absorbs light in a wavelength region of less than 400 to 600 nm, and 500 to 700 nm. A strong stimulation light is emitted to birds in the wavelength region of, for example, a sharp red light is emitted, and a strong stimulation of several times, for example, three times or more is given to birds and beasts compared to ordinary red pigments. And can control birds and beasts for a long time reliably and effectively.

Hereinafter, the present invention will be described in detail.
The “molded product” of the molded product for preventing birds and animals according to the first invention, which will be described in detail later, is obtained by molding a composition comprising at least a thermoplastic resin and a fluorescent dye in a predetermined blending ratio. Various forms such as a film, a sheet (including a plate-like material), a tape, a flat yarn, a monofilament, a composite monofilament, a woven / knitted fabric, a non-woven fabric, and a bag-like material are included and are not particularly limited.
A bag-like product and a flat yarn are produced using a film as a raw material, and a woven or knitted fabric or a non-woven fabric is produced using at least one of a flat yarn and a monofilament as a raw material.
The molding method used for producing the molded product for preventing birds and animals of the present invention is not particularly limited, and extrusion molding, injection molding, compression molding and the like can be applied, and particularly extrusion molding is preferably used. Is done.

The requirement of “0.001 to 2% by weight, which is the blending ratio of the fluorescent dye to the thermoplastic resin” of the first invention will be described.
The present inventors began to stimulate birds and beasts when the blending ratio of the fluorescent dye to the thermoplastic resin is about 0.001% by weight. As the blending ratio is increased, a large amount of light (fluorescence) is generated to the birds and beasts. In particular, when the blending ratio is 0.01% by weight or more, it is confirmed that radiant light that is a strong stimulus effective for the control of birds and animals is generated, that is, the blending ratio is 0.01. More preferably, it is more than wt%.
When the amount of the fluorescent dye is less than 0.001% by weight, the effect of emitting light is remarkably reduced, which is not preferable.

However, when the molded body is a sheet or plate, on the other hand, when the blending ratio increases, a phenomenon occurs in which the emitted light generated from one pigment particle is reabsorbed by another pigment particle, and this phenomenon occurs. The amount of light radiated to the outside of the molded body is increased with the addition of the fact that the thermoplastic resin of the molded body that is generated between a large number of pigment particles is somewhat cloudy and the transparency is reduced. Although the blending amount is too large, 2% by weight is confirmed by repeated execution by the present inventors as the limit amount of the blending ratio of the fluorescent dye.

In the process of creating the invention, the present inventors have repeatedly used the molded product for the prevention of birds and animals, and the fluorescent dye gradually eluted from the molded product, resulting in a decrease in color resistance. The phenomenon that the controlling effect disappears was confirmed, and this is assumed to be due to the compatibility between the thermoplastic resin and the fluorescent dye or the dispersibility of the fluorescent dye in the thermoplastic resin. It was confirmed that it is preferable to select a combination having good compatibility as a combination with the dye.

Moreover, according to the examination results of the present inventors, among the above-mentioned ones cited as the molded product for preventing birds and animals of the present invention, the flat yarn has a thickness of about 5 to 150 μm, preferably about 10 to 100 μm. Even if the monofilament is extremely thin with a fiber diameter of about 140 to 1000 μm, preferably about 220 to 700 μm, even if the compatibility with the thermoplastic resin is good, it is repeated as described above. If used, the fluorescent dye may elute from the molded body. In such a case, the amount of fluorescent dye that can be blended per unit volume is more preferably 0.5% by weight or less. confirmed.
The thickness of the film used as the material of the flat yarn is about 10 to 300 μm, preferably about 20 to 200 μm, and the thickness of the film used for the bag-like material is about 5 to 150 μm, preferably about 10 to 100 μm. Can be used.

  That is, the molded product for preventing birds and animals of the present invention not only has a strong irradiation light by generating a strong irradiation light, but also has high compatibility between the thermoplastic resin and the fluorescent dye, has good color resistance, and has a long period of time. In order to be usable, the blending ratio of the fluorescent dye to the thermoplastic resin is preferably 0.01 to 0.5% by weight, particularly 0.02 to 0.3% by weight. preferable.

As described above, the film, flat yarn, and monofilament of the molded product for preventing birds and animals of the present invention are extremely thin or thin molded products, and the amount of the fluorescent dye is limited. It is assumed that the total amount of fluorescence generated from the dye will decrease.
However, since the surface of these extremely thin or thin molded bodies produced by various molding methods is not optically smooth but rough irregularities, the emitted light generated from the fluorescent dye inside the molded body However, the diffuse reflection on this rough surface increases the amount of light radiated from the molded body to the outside due to the diffuse reflection effect. Further, when these molded bodies are exposed to light from the outside, they are also diffusely reflected on the rough surface. Therefore, it is considered to be a strong stimulus for birds and beasts.
That is, in the case of films, flat yarns, and monofilaments, this diffuse reflection effect is added, and even when a fluorescent dye is blended with an upper limit of 0.5% by weight, a sufficient amount of light that can be a strong stimulus to birds and beasts is emitted. The amount of radiated light does not change even if it is added in an amount of more than 0.5% by weight. Rather, the amount of radiated light may decrease due to reabsorption phenomenon or dye elution phenomenon. Considering the increase in cost when used for the above, there are few advantages.

Furthermore, secondary processed bodies such as composite monofilaments, woven and knitted fabrics, etc., produced from these films, flat yarns and / or monofilaments, can be obtained by combining or weaving a plurality of these materials. In order to form various uneven states between the materials, the above-mentioned effects of the film, flat yarn and monofilament are exerted more strongly, and the light emitted from the molded body is extremely strong against birds and beasts. It is thought to give a stimulus.
The woven or knitted fabric made of flat yarn or monofilament will be described in detail later.

Examples of the thermoplastic resin used in the molded article for preventing birds and animals according to the present invention include polyester, nylon, polycarbonate, polyacrylate, polymethacrylate, polyolefin, polyvinyl chloride, and the like, and a translucent resin is used.
In particular, in order to be able to reliably and effectively control birds and beasts for a long period of time, the molded object for preventing birds and animals of the present invention needs to be stable for a long period of time. As described above, the dispersibility and compatibility between the thermoplastic resin and the fluorescent dye are good, and it is desirable that the dye does not come out of the molded body. Therefore, among the above thermoplastic resins, polyester, nylon, polyolefin Polyester is particularly preferably used.

Among these, it is preferable to use a polyester obtained by appropriately selecting and synthesizing the constituent acid component and glycol component for the above purpose.
As polyester, terephthalic acid, isophthalic acid, succinic acid, adipic acid, 2,6-naphthalenedicarboxylic acid and the like as acid components, and ethylene glycol, 1,4-butanediol, 1,6-hexanediol, , 4-cyclohexanedimethanol, cyclohexanediol, and the like, which are obtained by polycondensation, include copolymers in which a part of the acid component and / or glycol component is replaced with a copolymerization component. Specifically, polyethylene terephthalate and polybutylene terephthalate are used.

As nylon, nylon 6, nylon 6,6, nylon 6,10, nylon 11, nylon 12, nylon 6/11, nylon 6/12, or the like is used.

Furthermore, as the polyolefin, polyethylene resins such as high density polyethylene, medium density polyethylene, branched low density polyethylene, linear low density polyethylene, ethylene / α-olefin copolymer produced using a metallocene catalyst, Polypropylene resins such as a propylene homopolymer, an ethylene-propylene block copolymer, and an ethylene-propylene random copolymer are used.

  The fluorescent dye to be blended with the thermoplastic resin is not particularly limited as long as the emitted light (fluorescence) generated by irradiating the molded product with sunlight is irritating to the eyes of birds and animals and exhibits a controlling effect.

Therefore, when the emitted light is desired to be yellow, orange or red, the light absorption wavelength region is preferably 400 to 600 nm, particularly preferably 470 to 600 nm. A fluorescent dye having a wavelength region of 500 to 700 nm is effective for stimulating the eyes of birds and animals.
However, when the emitted light is selected to be red, the fluorescent dye preferably has a light absorption wavelength region of 400 to 600 nm, more preferably 470 to 600 nm, and radiation light generated by irradiating sunlight. It is preferable to use one having a wavelength region of 600 to 700 nm, and a molded article produced by extrusion molding is preferable, which emits a sharp red light, and is several times, for example, 3 times that of a normal red pigment. The above strong stimulation can be given to birds and beasts.

In the present invention, the fluorescent dye includes a fluorescent dye and a fluorescent pigment.
Examples of the fluorescent dye include nonionic fluorescent dyes, for example, violanthrone dyes, isoviolanthrone dyes, vilantron dyes, flavantron dyes, perylene dyes and bilene dyes, xanthene Dyes, thioxanthene dyes, naphthalimide dyes, naphtholactam dyes, anthraquinone dyes, benzoanthrone dyes, coumarin dyes, etc., among these having the above absorption wavelength range and light in the above wavelength range The radiating dye can be appropriately selected and used.
These fluorescent dyes can be used alone or in combination of two or more.

Examples of the perylene dye include Yellow 083, Orange 240, and Red 305 of trade names Lumogen F series manufactured by BASF Akchengezelshaft.
Moreover, as a naphthalimide type pigment | dye, the product name Lumogen F series Violet 570, Blue 650 etc. by the BASF Akchengezelshaft company are mentioned, for example.

  These fluorescent dyes are used by dissolving in an organic solvent such as glycols, aromatic hydrocarbons, chlorinated hydrocarbons, esters, ketones or amides, or water.

Next, the woven or knitted fabric of the present invention for preventing birds and animals will be described in detail.
As the form of the yarn used to manufacture the woven and knitted fabric, a flat yarn obtained by slitting a film produced by various molding machines and then stretching, a split yarn obtained by splitting a flat yarn, or a circular or A single-layer type such as a monofilament obtained by stretching a filament extruded from a special-shaped nozzle or a multifilament in which low-definition filaments are converged, or a composite yarn such as a multi-layer type, a core-sheath type, or a parallel type is used without limitation.

A film used for producing a flat yarn is prepared by first supplying a mixture prepared by using a mixer such as a Henschel mixer with a predetermined ratio of a fluorescent dye to a thermoplastic resin, and kneading the mixture. The thermoplastic resin and the fluorescent dye can be directly supplied to an extruder and kneaded, and then can be produced by employing a known method such as an extrusion molding method, an injection molding method, or a compression molding method.
However, a masterbatch in which a high-concentration fluorescent dye is previously contained in the same or similar resin as the base thermoplastic resin is manufactured, and the film is formed by adjusting the content to a predetermined content during film formation. The method is preferably adopted.

The flat yarn will be described by taking as an example the case of using a film by an extrusion method. For example, a kneaded product made of the above thermoplastic resin such as polyolefin, polyester or nylon and a fluorescent dye is put into an extruder, and a T die is used. It is formed by extruding in an amorphous state by the method or the inflation method and then cooling and solidifying. The resulting film is slit to a width of about 2 to 50 mm, preferably about 5 to 30 mm, stretched, and then heat treated.
In this case, the stretching process is performed at a temperature below the melting point of the high melting point thermoplastic resin and above the softening point of the low melting point thermoplastic resin. The heating method is any of a hot roll type, a hot plate type, a hot air type, etc. This method can also be adopted.
The slit thermoplastic resin film is heated and stretched by the difference in peripheral speed between the front and rear rolls. The draw ratio is 3 to 15 times, preferably 4 to 12 times, and more preferably 5 to 10 times.
If the draw ratio is less than 3 times, sufficient strength of the flat yarn cannot be obtained. On the other hand, if the draw ratio exceeds 15 times, the orientation in the drawing direction is too strong and the flat yarn is easily broken, and the production efficiency is extremely low. Inferiority is assumed. The single yarn fineness of the drawn yarn is usually 200 to 10,000 dtex (hereinafter abbreviated as dt), preferably 500 to 5000 dt.

The stretched thermoplastic resin yarn obtained above is woven using warp and weft to form a woven or knitted fabric to obtain a sheet.
The form of the woven or knitted fabric is not particularly limited. Examples of the woven fabric include plain weave, twill weave, imitation weave, leopard weave, woven fabric, etc. Can be mentioned.

In addition, as the above-mentioned thermoplastic resin nonwoven fabric, a fibrous material that has been melt-extruded using a thermoplastic resin, particularly polyolefin, polyester, nylon, or the like is randomly stacked, and the molten fibrous material is melt-bonded to form a sheet Either a melt-blow method for forming a sheet or a spunbond method for forming a sheet by melting and bonding the cooled fibrous materials with a hot embossing roll can be used.
Alternatively, a stretched thermoplastic resin yarn may be arranged at predetermined intervals along the background and overlapped to bond the intersecting portions to form a laminated nonwoven fabric.

  In the thermoplastic resin of the present invention, an antioxidant, a dispersant, a lubricant, an antistatic agent, a pigment, an inorganic filler, a cross-linking agent, a foaming agent, a nucleating agent and the like are usually used without departing from the spirit of the present invention. Additives may be blended.

Next, the second invention is an invention relating to a molded product for preventing birds and animals, wherein a fluorescent dye is adhered to the surface of a molded product made of a thermoplastic resin.
In this case, “attachment of fluorescent dye to the surface of the molded body” means that a fluorescent dye coating liquid is applied to the surface of the molded body to form a film made of fluorescent dye, and a dye is used as the fluorescent dye. As in the case of dyeing, the state of the fluorescent dye obtained by the surface treatment is generically referred to.
Furthermore, a woven or knitted fabric is formed once using a material such as a flat yarn or monofilament that does not contain a fluorescent dye, and then the woven or knitted fabric is immersed in a coating solution containing a fluorescent dye or dyed with a fluorescent dye. A fluorescent dye can be attached to the surface of the knitted fabric.

Examples of the thermoplastic resin used in the molded product for preventing birds and animals of the second invention include polyester, nylon, polycarbonate, polyacrylate, polymethacrylate, polyvinyl chloride, and the like as in the first invention.

Examples of polyester include terephthalic acid, isophthalic acid, succinic acid, adipic acid, 2,6-naphthalenedicarboxylic acid and the like as acid components, and ethylene glycol, 1,4-butanediol, 1,6-hexanediol as glycol components, , 4-cyclohexanedimethanol, cyclohexanediol, and the like, which are obtained by polycondensation, include copolymers in which a part of the acid component and / or glycol component is replaced with a copolymerization component. Specifically, polyethylene terephthalate and polybutylene terephthalate are used.

As nylon, nylon 6, nylon 6,6, nylon 6,10, nylon 11, nylon 12, nylon 6/11, nylon 6/12, or the like is used.

Furthermore, as the polyolefin, polyethylene resins such as high density polyethylene, medium density polyethylene, branched low density polyethylene, linear low density polyethylene, ethylene / α-olefin copolymer produced using a metallocene catalyst, Polypropylene resins such as a propylene homopolymer, an ethylene-propylene block copolymer, and an ethylene-propylene random copolymer are used.

  The thermoplastic resin molded body is an extruded body obtained by extrusion molding of a thermoplastic resin, for example, various forms such as a film, a sheet, a tape, a flat yarn, a monofilament, a composite monofilament, a woven knitted fabric, and a nonwoven fabric. Can be formed by a known molding method.

The case of a woven or knitted fabric will be described as an example of the molded body.
The yarns used for woven and knitted fabrics include flat yarns that are drawn by slitting the film, split yarns that are split from flat yarns, monofilaments that are drawn from circular or deformed nozzles, and low-fineness filaments. A single layer type such as a converged multifilament or a multi-layer type, a core-sheath type, a parallel type, etc. are used without limitation.

  In the case of flat yarn, the above thermoplastic resin, for example, polyolefin, polyester or nylon is put into an extruder, extruded in an amorphous state by T-die method or inflation method, and cooled and solidified film is about 2 to 50 mm. Preferably, after slitting to a width of about 5 to 30 mm, the film is stretched and then heat treated to form a flat yarn. In this case, the stretching process is performed at a temperature below the melting point of the high melting point thermoplastic resin and above the softening point of the low melting point thermoplastic resin. The heating method is any of a hot roll type, a hot plate type, a hot air type, etc. This method can also be adopted. The slit thermoplastic resin film is heated and stretched by the difference in peripheral speed between the front and rear rolls. The draw ratio is 3 to 15 times, preferably 4 to 12 times, and more preferably 5 to 10 times. If the draw ratio is less than 3 times, sufficient strength of the flat yarn cannot be obtained. On the other hand, if the draw ratio exceeds 15 times, the orientation in the drawing direction is too strong and the flat yarn is easily broken, and the production efficiency is extremely low. It is assumed that it is inferior. The single yarn fineness of the drawn yarn is usually 200 to 10,000 dtex (hereinafter abbreviated as dt), preferably 500 to 5000 dt.

  The stretched thermoplastic resin yarn obtained above is woven using warp and weft to form a woven or knitted fabric to obtain a sheet. The structure of the woven or knitted fabric is not particularly limited, and examples of the woven fabric include plain weave, twill weave, imitation weave, leopard weave, woven fabric, and the knitted fabric includes Russell knitting, tricot knitting, Miranese knitting and the like. Can be mentioned.

  In addition, as the nonwoven fabric of the thermoplastic resin, a fibrous material that is melt-extruded using thermoplastic resin, particularly polyolefin, polyester, nylon, or the like is randomly stacked, and the molten fibrous material is melt-bonded to form a sheet Either a melt-blow method for forming a sheet or a spunbond method for forming a sheet by melt-bonding cooled fibrous materials with a hot embossing roll can be used. Alternatively, a stretched thermoplastic resin yarn may be arranged at predetermined intervals along the background and overlapped to bond the intersecting portions to form a laminated nonwoven fabric.

  In the thermoplastic resin of the present invention, an antioxidant, a dispersant, a lubricant, an antistatic agent, a pigment, an inorganic filler, a cross-linking agent, a foaming agent, a nucleating agent and the like are usually used without departing from the spirit of the present invention. Additives may be blended.

The fluorescent dye used for the surface treatment of the molded article has a high light stability that absorbs light in a wavelength region of 400 to less than 600 nm, and preferably emits light in a wavelength region of 470 to 600 nm. A fluorescent dye is used. In the present invention, the fluorescent dye includes fluorescent dyes and fluorescent pigments.
Examples of the fluorescent dye include nonionic fluorescent dyes, for example, violanthrone dyes, isoviolanthrone dyes, vilantron dyes, flavantron dyes, perylene dyes and bilene dyes, xanthene Dyes, thioxanthene dyes, naphthalimide dyes, naphtholactam dyes, anthraquinone dyes, benzoanthrone dyes, coumarin dyes and the like. These fluorescent dyes can be used alone or in combination of two or more.
Examples of the perylene pigment include trade names Lumogen F series Yellow 083, Orange 240, and Red 305 manufactured by BSF Akchengezelshaft. Examples of naphthalimide dyes include Violet 570 and Blue 650 of the trade name Lumogen F series manufactured by BASF Akchengezelshaft.

Examples of the surface treatment of the molded body include a method in which the molded body is surface-coated or dyed with a fluorescent dye as described above.
As a method of coating the surface of the molded body with a fluorescent dye, a dip coating method in which the molded body is dipped in a fluorescent dye solution and applied, a spray coating method in which a fluorescent dye solution is sprayed and applied to the surface of the molded body, Examples thereof include a method of applying a fluorescent dye solution to the surface of the molded body using brush coating or a roll coater. The coating amount of the fluorescent dye is 0.01 to 2.0% by weight, preferably 0.05 to 0.5% by weight with respect to the molded body.
When the coating amount of the fluorescent dye is less than the lower limit, the effect of absorbing light in the wavelength region of 400 to less than 600 nm and emitting light in the wavelength region of 500 to 700 nm is remarkably reduced. This is not preferable because a problem of dispersibility occurs and the effect of addition does not increase any more, and the cost increases.

Examples of the method for dyeing the molded product include a method of dyeing the molded product in a dispersion solution of a fluorescent dye, and the same method as that for a normal disperse dye can be employed.
The dyeing temperature is in the range of 60 ° C. to 140 ° C., and when the dyeing is carried out while maintaining the tension applied to the article to be dyed in a substantially non-tensioned state, the strength of the molded product is not lowered, It is preferable because good dyeability can be obtained. The dyeing operation can be either continuous processing of web-like materials or batch processing of single sheets.

  Next, the present invention will be described more specifically with reference to examples.

As a result, the resulting Russell knitted net (mesh is 2.0 cm x 2.0 cm, size is 1.5 m ² ) is hung on a garbage bag collected in a garbage collection place to protect the garbage. Damage was seen due to the scattering of garbage by crows and cats.

Example 17:
A film having a thickness of 60 μm made of polyester and fluorescent dye was prepared in the same manner as in Example 1 except that 0.03% by weight of fluorescent dye RED 305 was blended with the polyester described in Example 1.
Cut this film to prepare two 90cm x 120cm square films, and after superposing them, add three sides at a temperature of about 120 ° C and heat-seal to produce a bag-like material, Two same bags were prepared.

This produced bag-like product is used as a prototype garbage bag, and about 500 g of unprocessed rice from each cafeteria is delivered and closed.
In addition, about 500 g of leftover food is similarly delivered to two commercially available polypropylene garbage bags and then closed.
They were placed in a garbage dump where crows flock frequently and installed early in the morning to observe how crows eat leftovers.
As a result, the two prototype raw garbage bags remained in the initial state without any evidence of leftovers even after 6 hours had passed since they were installed in the garbage disposal site.
On the other hand, about the commercially available garbage bag, 45 minutes after installation, the bag was devoured and punctured, and after 2.8 hours, almost all of the leftover food was eaten.
As a result, it was confirmed that one film of the molded product for preventing birds and animals of the present invention radiates strong fluorescence when irradiated with sunlight.

Example 18:
As a polyester, a polymer obtained by polycondensation of a glycol component having a weight ratio of ethylene glycol / 1,4 cyclohexanedimethanol of 60/40 and an acid component of terephthalic acid (trade name: PET-G manufactured by SK Chemicals) Using a brand: S2008), a film was formed by a T-die method using a 65 mmφ extruder at a melting temperature of 260 ° C., and the cooled and solidified film was slit and stretched to obtain a flat yarn having a fineness of 600 dt.
On the other hand, high-density polyethylene (MFR = 0.7 g / 10 min, density = 0.957 g / cm 3, Tm = 129 ° C.) was melt-extruded with a monofilament forming die, then cooled and solidified, and then stretched to obtain fineness. A 700 dt monofilament was obtained.
The obtained monofilament having a fineness of 700 dt was used as a chain knitting yarn, the obtained flat yarn having a fineness of 600 dt was used as an insertion yarn, and a raschel knitting machine was used to knit a raschel knitting net.
The obtained Russell knitted net is used as a fluorescent dye, soaked in a fluorescent dye solution containing 0.5% by weight of Lumogen F series Red 305, manufactured by BSF Akchengezelshaft, and dried. Then, a Russell-knitted net (mesh of 2.0 cm × 2.0 cm, size of 1.5 m ² ) coated with a fluorescent dye was obtained.
When the resulting Russell net was hung on a garbage bag collected in a garbage collection site to protect the garbage, there was no scattering of garbage by crows and cats, and no damage was seen.

Comparative Example 2:
In Example 18, the same procedure was performed except that the surface of the fluorescent dye was not coated.
As a result, when the obtained Russell knitted net was hung on a garbage bag collected in a garbage collection site to protect the garbage, damage was seen due to scattering of garbage by crows and cats.
